Greens powders may help fill nutritional gaps in your diet

Going green, in the form of powdered greens, is all the rage. If you haven't noticed, they're enjoying a moment in the spotlight; they seem to be everywhere, but before you jump into the world of greens, it's worthwhile taking stock of what you need to know. Eating greens (as well as all other fruits and vegetables) has been linked to numerous health benefits, but many people don't consume the recommended two cups of fruits and three cups of vegetables per day. Greens powders, which are made of dried, powdered vegetables, are a convenient way to get some of the nutrients found in vegetables, but they may not provide all of the same benefits that you get from eating real veggies.

Greens powders make it easy to get some nutrients from vegetables, although they aren’t a substitute for eating whole vegetables—which are much higher in fiber and other nutrients, suggests Maddi Osburn, RDN, LD. However, a greens powder can be helpful when you aren’t able to eat as much produce (if you’re traveling, for instance). Some greens powders contain a high amount of vitamins and minerals, which can essentially act as a multivitamin. While other greens powders contain primarily antioxidants, and may have little or no vitamins and minerals in them. Many greens powders also contain herbs, adaptogens, prebiotics, probiotics, digestive enzymes, and other added ingredients that may provide additional health benefits but are not necessarily suitable for everyone.

To select our top greens powders, our dietitians researched and reviewed several products on the market, evaluating for nutritional content, quality of ingredients, and safety. We tested 19 greens powders in the Verywell Testing Lab and rated each product for taste, texture, smell, third-party testing, nutrition, and value. Many of our top choices are certified third-party tested to ensure their ingredient list is accurate and free of contaminants. If there are adaptogens or other additions in these greens powders, we call them out and explain who may want to avoid them so you can make the best choice for your individual needs.

Editor's Note

Our team of registered dietitians reviews and evaluates every single supplement we recommend according to our dietary supplement methodology. From there, a registered dietitian on our Expert Review Board reviews each article for scientific accuracy.

Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs and which dosage to take. Some greens powders may not be recommended for pregnancy or breastfeeding, or they might interact with certain medications or worsen symptoms of chronic illnesses.

Pros
  • Third-party tested

  • No added sweeteners

  • USDA Organic

  • Pleasant fruity taste

Cons
  • Some ingredients, including digestive enzymes, may not be suitable for all

  • Can take extra mixing to dissolve clumps

Who It's For

This is a great choice for those looking for an organic, comprehensive greens powder with additional probiotics and digestive enzymes.

Why We Recommend It

The Garden of Life Raw Organic Perfect Food Green Superfood offers an extensive fruit, vegetable, and sprouted grain and seed blend in addition to greens, and it has been voluntarily tested and approved by ConsumerLab's Quality Certification Program. It provides 70 percent of the recommended daily amount of vitamin K, 35 percent of vitamin A, 10 percent of riboflavin, and smaller amounts of folate, calcium, iron, magnesium, manganese, and potassium.

It contains an extensive list of ingredients that may provide additional benefits beyond those of other greens powders, although if you have a food allergy or are taking any prescription medications, it's always important to read the label. For example, it contains digestive enzymes, so if you have any digestive problems, check with a healthcare provider to see if these ingredients could affect your symptoms. Certain digestive enzymes can help with specific digestive difficulties, but the enzyme(s) have to be matched to the condition, and they likely provide no benefit to healthy people.

It also contains probiotics, including two Lactobacillus probiotic strains that may help alleviate certain digestive conditions and support a healthy gut microbiome. However, research is still preliminary, and there are currently no clear recommendations for using this combination of probiotics in the general population.

Garden of Life Raw Organic Perfect Food Green Superfood is organic, gluten-free, and vegan. We like that the flavor has some fruity notes to complement the grassy taste of a greens powder.

Things To Consider

  • This greens powder is particularly high in vitamin K—with around 70 percent of the recommended daily allowance—which can be beneficial for some people but may pose a risk for people taking certain medications. Vitamin K can interact with blood thinners, cholesterol medications, and even some antibiotics.
  • The digestive enzymes and probiotics it contains may not be suitable for everyone, so be sure to check with a health care provider if you have any preexisting conditions.
  • The texture is a bit clumpy, requiring more mixing effort to fully dissolve. Alternatively, it would be a good option to blend into a smoothie.
Amazing Grass Greens Blend Superfood

Our Ratings
  • Flavor
    5/5
  • Texture
    4/5
Pros
  • Third-party tested

  • Contains algae

  • More affordable than some options

Cons
  • Contains prebiotics, probiotics, rosehip, and digestive enzymes, which may not be suitable for everyone

  • Has a grassier flavor and slightly grainy texture

Key Specs:

Serving Size: 1 scoop (8 grams) | Servings Per Container: 30 | Gluten-Free: Yes | Organic: No | Added Sweetener: Some blends contain stevia | Third-party tested: Yes

Who It's For

This is a more budget-friendly alternative to our top pick, with a similar nutrient composition, including added probiotics, herbs, and digestive enzymes. If you like matcha, this has a similar flavor profile.

Why We Recommend It

Amazing Grass Greens Blend is third-party tested for purity and potency and contains a blend of fruits, vegetables, grasses, prebiotics, probiotics, and digestive enzymes. Each serving provides 58 percent Daily Value of vitamin K, 18 percent DV of vitamin C, and smaller amounts of vitamin A, calcium, and potassium. We also like that it contains 3 grams of fiber, which is relatively high for a greens powder.

This blend contains two types of algae—spirulina and chlorella—which have been shown to have potential health benefits related to their nutrient and antioxidant content, including reduced risk of certain chronic diseases.

The added prebiotics, probiotics, and digestive enzymes may be beneficial for some people but may not be good for others, especially those with digestive disorders.

Things To Consider

  • This powder blends well, but it does have more of a grainy texture as compared to others. When it comes to taste, it is definitely on the grassier side, with a similar taste to a matcha drink.
  • Amazing Grass contains rosehips, which may interact with antacids, estrogens, lithium, and medications that affect blood clotting.
Pros
  • Organic, simple ingredient list with no added sweeteners

  • Contains 14 grams of protein

  • Third-party tested

  • Adds a hint of creaminess from collagen and coconut powder

Cons
  • Large serving size

  • Not vegetarian

Key Specs:

Serving Size: 2 scoops (24 grams) | Servings Per Container: 12 | Gluten-Free: No | Organic: No | Added Sweetener: No | Third-party tested: Yes

Who It's For

With 14 grams of protein per serving from collagen (in addition to greens), this is a great all-in-one powder option to boost your protein, nutrient, and antioxidant intake.

Why We Recommend It

We love the simple ingredient list of Vital Proteins Collagen Beauty Greens, which contains a mix of collagen peptides, dehydrated greens, hyaluronic acid, and a small number of probiotics. Vital Proteins is known for its high-quality protein powders and thoughtful ingredient sourcing. This powder is third-party tested for heavy metals and other potential contaminants and is also produced in an NSF Certified manufacturing facility. It contains 24 percent Daily Value of vitamin A and 17 percent DV of iron, as well as smaller amounts of folate, potassium, and other nutrients.

While the research on the benefits of oral collagen supplements is mixed, there is some evidence to suggest that collagen peptides may promote skin and joint health. Collagen can be a good source of protein—this powder contains 14 grams and can be used as a protein powder in your morning smoothie. Vital Proteins also contains hyaluronic acid, which may help improve skin elasticity and reduce wrinkles. While the research on this is limited, one randomized control trial did show that oral hyaluronic acid can lessen wrinkle formation and improve skin.

It is flavored with coconut water powder and vanilla bean powder. The flavor of this powder has a hint of creaminess due to the collagen, and the vanilla and coconut also give it a subtly sweet, creamy flavor with some earthiness from the greens.

Things To Consider

  • This powder is on the earthier side for flavor, and it's more difficult to fully blend with just water, so it works best blended into a smoothie.

Our Ratings
  • Flavor
    5/5
  • Texture
    4.2/5
Pros
  • Third-party tested

  • Good source of iron

  • Contains 12 grams of protein

Cons
  • Some may find the vanilla flavor too strong

Key Specs:

Serving Size: 1 scoop (20 grams) | Servings Per Container: 30 | Gluten-Free: Yes | Organic: Yes | Added Sweetener: Coconut sugar and stevia ⏐Third-party tested: Yes

Who It's For

This is another great option if you are looking for an all-in-one greens and protein powder, and if you are looking to mask the taste of greens. It contains a high amount of iron as well, making a good choice for vegans and vegetarians looking to boost both their protein and iron intake.

Why We Recommend It

Sakara Organic Protein + Greens Super Powder contains a plant-based protein blend including pea, hemp seed, and sesame protein, offering 12 grams of protein with all essential amino acids. The greens blend is made with spirulina, wheatgrass, barley grass, and chlorella—a good source of phytonutrients and omega-3s DHA and EPA. It also contains 25 percent Daily Value of iron, making it a great choice for vegetarians looking to increase their iron intake.

If you're looking for a product that masks that typical greens earthy flavor, this option may be good for you, as this tastes more like a protein smoothie than a greens powder. This powder has a slightly sweet, vanilla-coconut taste from coconut milk, vanilla powder, and a small amount of stevia that blends well into smoothies. For a nutrient-dense, high-fiber, high-protein smoothie, blend it with fruit, spinach, nut milk, and nut butter.

This product is made with simple, USDA organic ingredients and is third-party tested. Sakara offers the option to purchase one time or as a renewing subscription at a slightly lower price point.

Things To Consider

  • This product definitely differs from your typical greens powder, with a creamier texture and strong vanilla flavor, which some may not prefer.
  • While it is free of common allergens, it is processed in a facility that processes wheat, milk, eggs, soy, and tree nuts, so it may not be suitable for those with certain severe food allergies.

Pros
  • NSF Certified for Sport

  • High in many vitamins and minerals

  • Easy to dissolve in water and smooth texture and great taste

Cons
  • Some ingredients could interact with medications

  • Exact amounts of ingredients are not listed in proprietary blends

Key Specs:

Serving Size: 1 scoop (12 grams) | Servings Per Container: 30 | Gluten-Free: Yes | Organic: No | Added Sweetener: No⏐Third-party tested: Yes

Who It's For

If you are looking for a greens powder that has a lot of nutrients packed in one serving, AG1 could be a good fit for you. Think of this powder as an alternative to a daily multivitamin. It also contains additional adaptogens, digestive enzymes, and probiotics if you are looking to add those supplemental ingredients to your routine.

Why We Recommend It

Athletic Greens (AG1) has an impressive 75-ingredient list in its greens powder, mainly from whole foods, vitamins, and minerals. The company has strict manufacturing standards with 100 percent traceable ingredients for each batch produced. Their greens powder is vegan, contains no artificial ingredients or pesticides, and is free of common food allergens, including gluten. We also appreciate it has strong third-party testing and is NSF Certified for Sport.

This greens powder could serve as a multivitamin—it is a good source of many vitamins and minerals (except iron). It also contains probiotics, digestive enzymes, and adaptogens. Adaptogens are plants that are thought to help the mind and body better handle—or adapt to—stress. AG1 contains the adaptogens Rhodiola rosea (R. rosea), ashwagandha, and medicinal mushrooms reishi and shiitake to help support the way your body responds to stress. Adaptogens have been used for centuries in some cultures for many health benefits, but it's important to note there are limited long-term studies on how adaptogens—and in what dose—impact our health.

AG1 offers a subscription service to make auto-renewing easier and at a lower price point, which can be appealing since it's a more expensive option. This greens powder can be purchased in a 30-serving pouch or in convenient travel packs to take on the go.

What stands out to us about AG1 is how well it dissolves in water; we didn't notice any clumps or grainy texture. We love that the flavor is pleasant, on the fruitier side, and not bitter at all!

Things To Consider

  • While appealing to some, it's important to note that the long ingredient list includes adaptogens, plant extracts, mushroom powders, digestive enzymes, and probiotics. These ingredients may not be best for everyone, especially if you are taking any medications, are pregnant, or breastfeeding. In these instances, we recommend consulting a healthcare professional before you try AG1.
  • If you already take a multi, we recommend consulting a healthcare professional before taking this greens powder to make sure you're not getting too much of some nutrients.

Adaptogens in Athletic Greens

Rhodiola rosea is a plant that grows in mountainous regions in Asia and Europe. Some studies suggest it may help combat fatigue, exhaustion, and stress. However, more research is needed on optimal dosing and long term effects. Rhodiola can also interact with immunosuppressants, any medications broken down in the liver, those used for diabetes, or high blood sugar.

Ashwagandha is an adaptogen associated with increased energy levels, improved sleep, and reduced anxiety. The long term safety and recommended dosing of ashwagandha is not well known from research. It's important to note ashwagandha may also interact with several medications, including immunosuppressants, sedatives, thyroid hormones, blood pressure medications, diabetes medications, and other herbs or supplements.

Medicinal mushrooms reishi and shiitake can also act like adaptogens and may have other health benefits like helping to lower inflammation and blood pressure. Reishi mushrooms may interact with blood pressure, diabetes, and blood clotting medications. High doses may also increase risk of bleeding—something to consider for those with blood disorders and who have a surgery in coming weeks. The safety of taking these mushrooms during pregnancy and breastfeeding is also not well known.

Pros
  • Third-party tested

  • Small serving size and versatile use

  • Contains fermented greens and algae

Cons
  • Lower in vitamins and minerals

  • Contains moringa and caffeine, which may not be a good choice for some

Key Specs:

Serving Size: 1 teaspoon (3 grams) | Servings Per Container: 90 | Gluten-Free: No | Organic: Yes | Added Sweetener: Monk fruit extract and stevia ⏐Third-party tested: Yes

Who It's For

This is a versatile greens powder that can be mixed into a variety of beverages and foods, packing a high dose of antioxidants into just 1 teaspoon. It contains some iron, but few other vitamins and minerals, making it a good choice for those looking for just antioxidants from their greens powder, as well as a boost of caffeine.

Why We Recommend It

The Dr. Mercola fermented greens powder contains a blend of fermented grasses, greens, vegetables, herbs, matcha, and algae, including chlorella and spirulina. Fermenting fruits, vegetables, and other foods may increase the body's ability to use and benefit from the antioxidants found in those ingredients. We like that this powder has both spirulina and algae, as both have been shown to offer a number of health benefits, including lowering cholesterol and blood pressure.While it does contain 30% Daily Value of iron, it is mostly beneficial for its antioxidant content.

The flavor of fermentation may throw some people off, as it is more tangy and similar to a vegetable broth, but the added natural sweeteners (monk fruit and stevia) help to neutralize the bitterness. While some may appreciate the taste with just water, this greens powder can work well when mixed into more savory liquids. We like the nutrient density of this powder and how well it blends without clumps. It may work best when mixing this into a soup or a green vegetable smoothie.

Things To Consider

  • This greens powder contains yerba mate and matcha, both of which contain caffeine. If you are sensitive to caffeine, are pregnant, or take a medication that could interact with caffeine, you may want to avoid this product.
  • It also contains moringa, an herb that can affect how medications are broken down in the liver, especially thyroid medications and those used for diabetes. If you're taking any medications, review this product with a healthcare provider before using it.

Pros
  • NSF Certified for Sport

  • High in antioxidants

  • Tastes like a fruity, mint lemonade

Cons
  • Contains herbal ingredients that may not be suitable for all

  • Can be clumpy

  • Lower in vitamins and minerals

Key Specs:

Serving Size: 1 scoop (10 grams) | Servings Per Container: 30 | Gluten-Free: Yes | Organic: No | Added Sweetener: Stevia | Third-party tested: Yes

Who It's For

This greens powder is NSF Certified for Sport, and contains ingredients high in antioxidants that may help in muscle recovery, making it a great choice for athletes.

Why We Recommend It

If you're a competitive athlete, it's essential to choose a product that is third-party tested for any ingredients banned by your sport. We recommend Biosteel Sport Greens powder for athletes because it meets the rigorous NSF Certified for Sport requirements. Some research suggests that fruit and vegetable juices and concentrates may promote muscle recovery. There is also specific research to connect tart cherry, an ingredient in this blend, with exercise recovery.

This powder contains a blend of different greens and berries, as well as other antioxidant boosters like green tea extract, CoQ10, and piperine. Note that this is primarily an antioxidant supplement (including vitamin C), but does not contain any significant amounts of other vitamins or minerals. It also contains an amino acid complex with l-glutamine and l-leucine, which is touted for exercise recovery, but the research on its effectiveness is inconsistent.

The Acai Lemonade flavor has quite a distinct smell of citrus, and that citrus flavor combines with almost a minty undertone for the flavor profile.

Things To Consider

  • Some may not love the aftertaste, and it does take a bit longer to mix this powder to get rid of clumps.
  • It contains several herbal ingredients including green tea extract and piperine that can interact with certain medications, and are not suitable for those with certain health conditions, or those that are pregnant or breastfeeding.
  • It contains inulin, a type of fiber which can be helpful for some people's digestion but problematic for others, including those with IBS.
KOS Show Me the Greens Powder

Amazon

Pros
  • Good source of iron

  • USDA Organic, non-GMO and produced in an NSF-certified facility

  • Contains algae

  • Pleasant green apple smell and taste

Cons
  • Not third-party tested

  • Can leave some sediment on the bottom

Key Specs:

Serving Size: 1 scoop (9.5 grams) | Servings Per Container: 28 | Gluten-Free: Yes, but not certified | Organic: Yes | Added Sweetener: Stevia and monk fruit extract | Third-party tested: No

Who It's For

This powder is for those who don't like the taste of traditional greens powders and want a fruity alternative with simple, organic ingredients.

Why We Recommend It

If you're looking for an organic and flavored greens powder, try KOS' green apple sorbet-flavored powder. It's sweetened with monk fruit and stevia, keeping the calorie content low while adding some sweetness. Although this product isn't third-party tested, it is USDA organic, non-GMO, and produced in an NSF-certified facility.

This product also has two grams of fiber and is a pretty good source of iron—three milligrams per serving (17 percent Daily Value). Iron is an important mineral to produce hemoglobin, which helps transport oxygen throughout the body. Having enough iron in your diet can also help reduce the risk of anemia.

In addition to the algae—spirulina, and chlorella—KOS keeps it simple with wheat grass, cabbage, kale, broccoli, apple, and green bell pepper powders. The smell and flavor of this greens powder is a strong green apple profile, which ranked high for taste among our testers. The fruity flavor helps tone down the earthy flavor of greens. This powder may be the best choice for people who really want the flavor of the greens masked.

Things To Consider

  • This powder contains a digestive prebiotic blend that may not be suitable for some individuals with digestive sensitivities and disorders, including those with IBS.
  • It also dissolves pretty well in water, but it may leave some sediment on the bottom of your glass.
  • It's not third-party tested for purity and potency.

  • USDA Organic

  • Easy to fully dissolve in water

Cons

  • Not the best taste if you don't like broccoli

Key Specs:

Serving Size: 1 /4 teaspoon | Servings Per Container: 30 | Gluten-Free: Yes | Organic: Yes | Added Sweetener: No | Third-party tested: Yes

Who It's For

This powder is a good option for those looking to boost their antioxidant intake with a simple, single-ingredient powder.

Why We Recommend It

If you want pure greens powder without unnecessary added ingredients, we recommend True Grace Superfood Powder Broccoli Microgreens because the only ingredient is powdered broccoli microgreens. Microgreens are miniature leafy greens that are high in antioxidants, and research suggests these small plants have anti-inflammatory and anti-bacterial properties.This powder does not contain vitamins and minerals, but it is a good option to boost your antioxidant intake.

This powder is certified regenerative organic, non-GMO, and grown on small US farms. Certified regenerative organic signifies that True Grace places a strong emphasis on restoring soil quality and promoting sustainable land use practices. It's also third-party tested by Alchemist Labs for purity and potency, including heavy metal testing.

If you aren't a fan of broccoli, you may not love the taste of this greens powder because it does have a mild broccoli flavor. The flavor isn't overpowering, but it is noticeable. We also like that this powder blends fully in water in just a few seconds, unlike other powders that may take 20-30 seconds to thoroughly mix in.

Things To Consider

  • Because there is no added sweetener and because it is from broccoli microgreens, note this option may have a stronger, more vegetable-forward flavor compared to others.
  • It does not contain vitamins and minerals.
Pros
  • Third-party tested

  • Physician approved as safe to take while pregnant or breastfeeding

  • Slightly sweet, pleasant flavor

Cons
  • Contains inulin, which may cause gas and bloating in some

  • Does not contain micronutrients

Key Specs:

Serving Size: 1 scoop | Servings Per Container: 30 | Gluten-Free: Yes | Organic: Some ingredients are organic | Added Sweetener: Stevia

Who It's For

If you are pregnant or breastfeeding, this greens powder is physician-approved safe option that is high in antioxidants and contains both probiotics and prebiotics.

Why We Recommend It

If you are pregnant or breastfeeding and looking to supplement with a greens powder, you want to pay particularly close attention to the ingredient list and supplement facts, as well as the quality of the product. Some greens powders contain adaptogens, herbal blends, and digestive enzymes, as well as high amounts of certain vitamins and minerals, which may not be suitable or safe to take while pregnant or breastfeeding. Perelel's Synbiotic Greens Powder is a physician-approved, safe option that is also third-party tested for purity and potency.

In addition to the antioxidant greens and fruit blend, it also contains a prebiotic fiber called inulin, which is a fermentable fiber that can help support a healthy gut microbiome. However, because it is fermentable, it can cause gastrointestinal symptoms like gas and bloating in some and may not be suitable for those with IBS. It also contains probiotics, which can help to populate the gut with beneficial bacteria. The use of probiotics is generally considered safe during pregnancy; however, the research behind strains, dosages, and their associated benefits is somewhat limited.

This powder comes in an acai berry flavor, made with natural flavorings, and slightly sweetened with stevia. We love that the flavor is subtly sweet, not overpowering, which may be helpful if you have morning sickness. It fully dissolves in water very quickly without leaving any clumps. The smell can be a little off-putting, as it is more earthy, but the taste is surprisingly pleasant.

It is non-GMO and free of gluten, dairy, soy, synthetic fillers, artificial colorings, and flavorings, Perelel offers a subscription service with monthly delivery (which also brings down the cost of the product), or you can buy it as a one time purchase.

Things To Consider

  • While it dissolves in water quickly, it can leave some sediment on the bottom especially if you don't drink it right away.
  • It contains inulin which may not be suitable for some, including those with IBS.
  • It does not contain vitamins and minerals.

Where We Stand

Garden of Life Raw Organic Perfect Food Green Superfood tops our list with its comprehensive plant blend rich in vitamins, minerals, and antioxidants, complimented with a great taste. If you are looking for a greens powder that also includes protein, try Vital Proteins Collagen Beauty Greens.

Greens Powders We Also Tested

While these didn't make our top picks, these greens powders are worth mentioning and may also suit your needs.

  • Ancient Nutrition Organic Super Greens: We like the flavor of this greens powder, and it's easy to blend. Plus, it's found in many stores so it's a convenient buy. Like some other powders, it does have adaptogens added which may not be best for all.
  • Your Super Super Green Mix: This powder ranks high for texture, as it mixes very quickly and thoroughly in water. It also has a pleasant earthy flavor, but it may not be best if you're looking to mask the flavor of greens.
  • Nested Naturals Super Greens: The chocolate flavor of this powder is overwhelming when mixed with just water and it also left a lot of clumps behind. It could be a good option to blend into smoothies.

How We Tested & Selected Greens Powders

Our team works hard to be transparent about why we recommend certain supplements; you can read more about our dietary supplement methodology here. We support supplements that are evidence-based and rooted in science. We value certain product attributes that we find to be associated with the highest quality products.

It's important to note that the FDA does not review dietary supplements for safety and effectiveness before they go to market. Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend.

In addition to our research, we tested 19 top-rated greens powders in The Verywell Testing Lab. We tested each product by mixing one serving with eight ounces of water (or the recommended amount) in a glass cup with a spoon. We reviewed each greens powder for flavor, aftertaste, texture, smell, and value, recognizing that this can be subjective and differ between individuals.

Our nutrition editors analyzed all of the greens powders for nutritional value and third-party testing. To determine the nutrition ranking, we looked at nutrient content, quality of ingredients and also additional ingredients, such as adaptogens. We also considered third-party testing and associated certifications for purity and potency. We combined these scores with the taste testing scores to arrive at a total score for each product.

Are Greens Powders Beneficial?

Some small studies have shown that greens powders might offer health benefits, such as lowering blood pressure, while studies looking at whether greens powders can increase energy have shown no benefit.

Fruit and vegetable powders have been shown to increase blood levels of vitamins as well as certain antioxidants, like carotenoids. Carotenoids are known to reduce the risk of certain cancers, age-related macular degeneration, and cardiovascular disease.

However, more research is needed to understand greens powders and whether or not they offer true benefits. Keep in mind that a great deal of the benefits of fruits and vegetables is offering nutrients in combination with dietary fiber, and greens powders usually offer little to no fiber. Greens powders cannot replace a well-balanced, varied diet, but they may be helpful to some people who aren't getting enough nutrients through food.

Greens powders may be beneficial for the following people:

  • People who don't eat many fruits and vegetables: "For those who may not like vegetables, greens powders may be a great alternative," says Andrew Akhaphong, MS, RD, LD. Although greens powders aren't an exact replacement for eating green vegetables (and other nutrient-rich produce), they can provide you with important nutrients to support health that may otherwise be missing.
  • People who travel frequently: It can sometimes be difficult to eat enough produce when you're constantly on the go, and greens powders can be an easy, portable way to meet some of your vitamin and mineral needs.
  • Some athletes: "Prolonged high-intensity exercise can increase vitamin and mineral needs. Some athletes have trouble meeting even their baseline nutrient needs, let alone an increased amount for optimal recovery," says Osburn. If you're a competitive athlete and decide to use a greens powder, be sure to choose a product that is third-party tested and free from any banned ingredients for your sport.
  • People with decreased absorption: People with certain illnesses like inflammatory bowel disease may have lower nutrient absorption. In these cases, a greens powder may help you achieve higher nutrient needs. However, be sure that there aren't any ingredients that can make your digestive problem worse.
  • People undergoing surgery: Emerging research suggests that fruit and vegetable powders could aid in recovery from surgery. This may be especially beneficial for people undergoing oral surgery or other surgeries that limit the ability to consume whole fruits and vegetables.

Who May Not Benefit From Greens Powders

The ingredients in greens powders vary significantly, so it's important to thoroughly read the label to make sure it's safe for you. Most greens powders contain more than just leafy green vegetables. Many contain grasses and alfalfa sprouts that could interact with medications or make some health concerns worse.

While they are often marketed as "food," greens powders are a supplement, and even food-based ingredients can be problematic for certain people in the quantities included. Also, because there is so much variation between products, a greens powder that is helpful for one person may not be good for another. The following people should be very cautious when considering a greens powder.

  • People taking prescription medications: Most greens powders include high amounts of vitamin K, which can interact with a variety of prescription medications. "Medications it may interact with include blood thinners, cholesterol-lowering medications, antacids, and those controlling seizures," says Akhaphong. If you are taking any prescription or over-the-counter medication, it's best to check with your healthcare provider before using a greens powder.
  • Pregnant or breastfeeding people: Many ingredients, such as adaptogenic herbs, prebiotics and probiotics, and digestive enzymes, are not well-studied in pregnant and breastfeeding people, so we don't know if they are safe. If you're taking a prenatal vitamin, adding a greens powder with added vitamins and minerals could lead to getting too much of some nutrients. Make sure to compare the labels of all supplements combined to the Tolerable Upper Limits set by the National Institutes of Health Office of Dietary Supplements and consult a healthcare professional.
  • People with end-stage kidney disease: "Depending on the product, a serving may contain 140 to 350 milligrams of potassium. Individuals with end-stage kidney disease may not be able to tolerate large amounts of potassium as the kidneys have a hard time removing excess potassium from their blood. A build-up of potassium, called hyperkalemia, may cause issues like dizziness, nausea, numbness, and a slow heart rate," says Akhaphong.
  • People with a wheat allergy: Most greens powders contain wheatgrass, which may be problematic for anyone with a wheat allergy. Of note, wheatgrass is typically harvested before the seed sprouts on the wheat, meaning it is usually gluten-free. However, anyone with celiac disease or who avoids gluten should choose a product that is certified gluten-free. Every greens powder contains different ingredients and may contain allergens, so be sure to check the ingredient labels to make sure it's safe for you if you have a food allergy.
  • Professional and collegiate athletes: While greens powders can be a helpful way to add nutrients to an athlete's diet, some supplements may contain ingredients that are banned for sport. "Not all greens powders are third-party tested, so it is especially important for athletes that may be drug tested to avoid using greens powders without proper third-party testing," says Osburn. Look for one that is NSF Certified for Sport, one of the most rigorous third-party testing certifications.
  • People with digestive disorders: Many greens powders contain ingredients that can worsen digestive problems. People with irritable bowel syndrome (IBS) who have trouble digesting certain carbohydrates, known as FODMAPs, may have trouble with greens powders. "Greens powders may contain FODMAPs like inulin or FODMAP-rich ingredients like some fruits and vegetables," says Akhaphong. Probiotics and other prebiotics can also worsen some digestive symptoms. If you are going to use a greens powder, "review all ingredients to ensure there aren't any added probiotics or prebiotics that could worsen your symptoms," says Suzie Finkel, MS, RD.
  • People taking other vitamin and mineral supplements: If you're taking a multivitamin or other vitamin or mineral supplement, check to make sure that you won't be consuming too much of any one nutrient. Most nutrients in supplement form (including in greens powders) can cause negative—or even dangerous—side effects when you consume too much. Review the Tolerable Upper Limits set by the National Institutes of Health Office of Dietary Supplements.

A Note of Caution with Alfalfa and Lead

Most greens powders contain alfalfa as a primary ingredient. Although people believe alfalfa to be helpful in treating many diseases, from diabetes to high cholesterol and digestive issues, there is no research to support this.

Regularly consuming high doses of alfalfa can be dangerous, especially for people with autoimmune disorders. Consuming high amounts of alfalfa may not be safe for pregnant or breastfeeding people as well as anyone with hormone-related conditions like breast cancer and endometriosis.

Alfalfa has also been shown to interact with anticoagulant medications, hormonal birth control, diabetes medications, and immunosuppressants.

Another potential concern with greens powders is lead. Lead is naturally found in many foods including green, leafy vegetables. Third-party tested greens powders will test for safe lead levels. However, it's important to note some third-party tested greens powders are still not recommended for regular use during pregnancy or for young children because they have a lower tolerance for lead. Therefore, always check with a healthcare professional if you are pregnant or before giving a greens powder to a child.

What to Look for in Greens Powders

Third-Party Testing

Supplements that are third-party tested are sent to a lab where they are tested for purity and potency to ensure they contain what they say they contain and do not contain any potential contaminants. Trusted third-party certifications include ConsumerLab.com, NSF, USP, and Informed Choice. However, these certifications can be difficult to obtain and expensive for manufacturers, so many companies choose not to get their products tested. If you are selecting a supplement that does not have third-party testing, we recommend choosing a trusted brand that does rigorous internal testing.

There is concern that some greens powders could be contaminated with heavy metals such as lead. In fact, when ConsumerLab.com tested 16 greens powders, they found high levels of lead in two products. The amount in these products was lower than the FDA standards for adults but higher than the much more stringent level that California proposition 65 puts forth, requiring a lead warning label. Children and pregnant people are more susceptible to the potentially harmful effects of consuming high levels of heavy metals.

Greens powders could also contain ingredients that are banned in high-level competitive sports, so finding one that is third-party tested specifically for sport, such as NSF Certified for Sport, is important for any competitive athlete.

Form

Greens powders are typically a mix of powdered leafy greens, vegetables, fruits, and extracts, and can also contain seaweed (like spirulina), probiotics, enzymes, herbs, and some have the addition of protein powder. While some powders contain high amounts of vitamins and minerals, there isn't research to understand the bioavailability (how much your body can absorb) of these nutrients in this form. It could be more or less than eating fresh or frozen fruits and vegetables.

Ingredients & Potential Interactions

It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included relative to the recommended daily value of that ingredient. Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking.

There are dozens of greens powders on the market to choose from. And while it may seem like they all offer similar benefits, many of them contain questionable ingredients or are not third-party tested by a reputable organization. Because greens powders have not been thoroughly researched and do not contain standardized ingredients, we are very selective with the brands we recommend.

It's important to be aware some ingredients in greens powders may warrant caution including:

Adaptogens: Greens powders that have adaptogens may warrant caution for those on medications, are pregnant, or breast feeding. For example, reishi mushrooms may interact with blood pressure medications, diabetes medications, and certain cancer treatments. Rhodiola or ashwagandha may interact with several antidepressants, blood pressure medications, diabetes medications, thyroid medications, cholesterol medications, immunosuppressants, and many other drugs that are broken down in the liver. We suggest talking with a healthcare provider before taking supplements with adaptogens if you take any medications—even ones not listed here. In addition, the safety of adaptogen supplements during pregnancy and breast feeding is not well known.

Digestive enzymes: In general, digestive enzymes provide no benefit to healthy people. While more research is needed, digestive enzymes also appear to provide little to no benefit to those with digestive disorders unless there is a known enzyme deficiency. "Digestive enzymes are best suited for those with diagnosed enzyme deficiencies such as lactose intolerance or other known digestive conditions that may cause symptoms like gas or bloating after eating certain foods. If you have been diagnosed with any of these conditions, taking a separate digestive enzyme supplement that targets your specific issue is recommended," says Finkel.

Probiotics: Many greens powder contain low levels of probiotics—about the amount you'd find in yogurt (though doses vary). While you may have heard that probiotics are beneficial, there are many different types of probiotics, and currently, no clear recommendations around which strains, strain combinations, or doses the general population may benefit from taking. "We do not have good evidence of any benefits of probiotic supplements for general health. Specific probiotic strains have been clinically shown to improve a small number of gastrointestinal conditions, but these are not the bacteria you would find in a powdered greens product," says Finkel. That said, probiotics can make some digestive conditions worse, so consult with your healthcare provider before taking a supplement that contains probiotics.

How Much To Take

Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs and to understand which dosage to take.

There is no standard dosage for greens powders, and ingredients and nutrient amounts can vary significantly. It's important to review the Recommended Dietary Allowance and Tolerable Upper Limits as set by the NIH for each ingredient to make sure you are consuming safe levels of each nutrient. Your body filters and eliminates excess water-soluble vitamins (B vitamins and vitamin C), so it's less likely these nutrients will cause harm. However, it is still possible to experience negative side effects from very high doses of these nutrients in supplement form. In addition, fat-soluble vitamins (vitamins A, D, E, and K) can be stored in fat tissue and are dangerous when consumed in excess. Many minerals can also be dangerous in very high amounts.

People taking multiple supplements are at higher risk for exceeding the Tolerable Upper Limits of vitamins and minerals. You can review your greens powder and any other supplements you are taking with a healthcare provider to ensure you are not exceeding the upper limits for any nutrient as established by the NIH Office of Dietary Supplements.

Frequently Asked Questions

  • Are greens powders good for you?

    Greens powders can provide many important vitamins, minerals, and antioxidants that can support health. They also may contain ingredients, such as spirulina and chlorella, that are primarily found in powder form and may offer some health benefits. The specific ingredients found in powders can vary significantly from one brand to another, and so do the potential benefits.

  • Are greens powders as good as fresh?

    In short, we don't know. There has been little research done on greens powders as a whole. The limited research that does exist doesn't suggest that they offer as many benefits as eating whole foods, but more research is needed.

    What we do know is that there are synergistic effects to eating whole foods. This means that the nutrients in whole foods work together, so you get more health benefits from eating foods in their natural form than you get from taking supplements. "While greens powders can help increase your fruit and vegetable intake, don't count on them to completely replace whole foods. Most don't contain all of the vitamins and minerals you need," says Osburn.

    One area where many greens powders fall short is in the fiber content. Greens and other vegetables provide fiber, which offers numerous health benefits, from better digestion to lower cholesterol. Fiber—when consumed from whole foods—is also linked to increased fullness with meals, which may help you eat less overall. But the same can't be said for fiber supplements. When it comes to greens powders, some greens powders contain no fiber, whereas others contain very little.

  • How do I make green powders taste better?

    Green powders can be quite bitter or have a grassy taste, but there are many ways to make greens powder taste better. Instead of drinking them plain, add them to a smoothie with fruit, which not only adds sweetness but includes fiber and other nutrients. But you don't have to drink them. "Add them into scrambled eggs for omelets, as a seasoning for a soup, into pancake or waffle batter, in baked goods, or mix into your favorite dip," says Akaphong.

  • Are greens powders worth it?

    Greens powders can be very expensive and, in most cases, are not necessary. However, they can be helpful for days when you don't have time to prepare fresh vegetables or if you are traveling and have limited access to fresh greens. Whether or not they are worth it really depends on your individual nutrient needs, diet, and lifestyle.

  • Do greens powders help with bloating?

    Some greens powder brands advertise that they relieve bloating, but the evidence for this is not supported by enough research. Certain brands of greens powders contain digestive enzymes, which may help to alleviate gastrointestinal side effects like bloating in those with certain digestive enzyme deficiencies, although they are unlikely to provide any benefit to those without deficiencies.

    Those with diagnosed enzyme deficiencies should consult a healthcare provider and may require prescription medication or a specific separate enzyme supplement. It is important to note that certain digestive enzymes and probiotic blends can make some digestive conditions worse, so they should be taken with caution for those with preexisting GI conditions.

    Additionally, some greens powders contain ingredients such as inulin, a fermentable fiber, and alternative sweeteners, which can both cause bloating in some individuals, particularly those with IBS.

  • How much do greens powders cost?

    The price of greens powders varies depending on the brand and the formula, but they usually range between $20-40. Products that are third-party tested and/or USDA Certified Organic may come with a higher price tag.

    Those with added ingredients like adaptogens, probiotics and digestive enzymes can also be more expensive.
