Only 12.3 percent of adults in the U.S. are hitting their fruit and vegetable requirements daily, according to the Centers for Disease control and Prevention (CDC). Luckily, greens powders can help bridge that gap. In addition to providing a hearty serving of fruits and veggies, there are many more benefits to greens powders, too. The micronutrients located in leafy greens as well as fruits help provide you with higher energy levels and improved immunity to help keep you healthy.

Many greens powders also offer prebiotic fibers and probiotics which support bloat relief and overall gut health. “Greens powders are packed with veggies, fruits, and lots of other ingredients like vitamins and herbs that are processed and ground into a fine powder. Because they're packed with so much in a scoop, they can potentially help fill nutrient gaps in someone's diet,” says Jamie Nadeau, RD, founder of The Balanced Nutritionist.

In this review, we discuss nine of our top picks for the best greens powders currently on the market in 2024.

This information is meant to be educational, be sure to talk to a medical provider or healthcare professional about your individual needs and appropriate dosages before adding a supplement to your routine.

  • Dosages per container: 30 servings

You’ve probably tried a greens powder that tasted like...well...greens—very earthy with a grass-like flavor. Probably not what you want to drink each day if you’re trying to up your nutrient intake. That’s why we recommend Legion Athletics Genesis as our best-tasting greens powder. Each scoop of this acai berry-flavored powder contains 70 calories and zero sugar, making it a great keto-friendly option. We also love that this powder is soy-free, dairy-free and plant-based.

Legion Athletics Genesis contains multiple nutrients and vegetables like reishi mushroom, maca and traditional Chinese medicine herbs like astragalus membranaceus; plus flavors of apple, pineapple, and natural, zero-calorie stevia leaf extract sweetener. Spirulina rounds out this robust green superfood powder. Experts say spirulina is a powerful antioxidant that may fight inflammation and is good for your heart.

This greens powder gets rave reviews for its flavor on the company’s website, with one user writing, “This is one of the best tasting greens supplements I have tried. It dissolves very well with water and a few shakes and goes down smooth.” Another user raved about the acai berry taste in particular, writing, “Whether on its own in water or mixed in a smoothie or protein fluff, it really enhances the flavor.”

Prebiotics are the food source for our stomach’s microorganisms which metabolize and ferment, becoming beneficial to our gut health. Prebiotics offer several health benefits for our gut and more, such as helping to regulate bowel movements, improving bone density and even boosting our immune system. 

Each scoop of Transparent Labs Prebiotic Greens contains important prebiotic fibers like chicory root, banana and Jerusalem artichoke fiber. You’ll also get added benefits of superfoods spirulina and chlorella, which may reduce inflammation and contain powerful antioxidants.

This product, although it’s not a meal replacement, offers a well-rounded greens powder with a solid 70 calories.

Best Greens Powder for Inflammation: AG1

AG1 is a greens powder containing vitamins, minerals, superfoods, antioxidants, enzymes, therapeutic mushrooms, prebiotics and probiotics.

Key info:

  • Buyer rating: 4.5/5 (AG1 website)
  • Certifications: NSF Certified for Sport
  • Key greens, minerals and vitamins: Ashwagandha, lactobacillus acidophilus, bifidobacterium
  • Sugar/sweetener: None
  • Dose: 1 scoop (12 grams)
  • Dosages per container: 30 servings
  • Taste & texture: Earthy, citrusy flavor (similar to pineapples); mixes easily, but needs to be shaken up after sitting

AG1 is a greens powder that has 75 vitamins, minerals and micronutrients sourced from whole foods. It’s intended to supplement any and all nutrient gaps you may have in your diet. However, there are three key ingredients that make AG1 the best greens powder for inflammation: ashwagandha, lactobacillus acidophilus and bifidobacterium.

Ashwagandha has been used in traditional medicine for centuries, and it has well-documented anti-inflammatory properties if you supplement daily with between 250 and 500 milligrams. It is unknown how many milligrams of ashwagandha AG1 has because it is part of a 2,732-milligram blend in the formula.

AG1 also contains two probiotic strains: lactobacillus acidophilus and bifidobacterium. Lactobacillus acidophilus has been shown in some studies to reduce inflammation in the upper and lower intestines, which can allow healthy gut bacteria to grow and relieve chronic GI symptoms like bloating, gas pain, nausea and diarrhea. Similarly, bifidobacterium reduces inflammation in the intestinal barrier, which can keep your body from absorbing bad bacteria that lead to viral infections and seasonal respiratory infections.

Pros:

  • All-natural ingredients sourced from whole foods
  • Has a relatively pleasant taste for a greens powder
  • Formula reviewed by a scientific advisory board

Cons:

  • It is unclear how much of each ingredient is contained in the proprietary blends
  • A common complaint among users is constipation after using AG1

Best Budget Greens Powder: KOS Show Me the Greens

A lime green and cream colored container of KOS Show Me the Greens powder supplement in Green Apple Sorbet flavor

Key info:

  • Buyer rating: 4.2/5 (Amazon)
  • Certifications: Non-GMO, vegan, organic, produced in NSF certified facility
  • Key greens, minerals and vitamins: Organic spirulina, organic chlorella, organic wheat grass, organic oat grass
  • Sugar/sweetener: Stevia
  • Dose: 1 scoop (9.5 grams)
  • Dosages per container: 28 servings
  • Taste & texture: Green Apple Sorbet flavor; most reviews say it tastes true to the flavor and mixes well

Scan the shelves of any health food store or look online, and you'll give double takes to the prices for greens powders. These supplements are expensive, probably because of the lengthy nutrient lists and expensive manufacturing processes, but you can find quality greens powders for around $1 per day if you know where to look (fortunately, we do).

KOS Show Me the Greens powder stands out as a wallet-friendly greens powder option, costing around $1.32 per serving size (compared with $3.30 per serving for a single pouch of AG1). One serving of KOS Show Me the Greens is a 9.5-gram scoop that, according to reviewers, easily mixes with cold water in a shaker bottle. True to the description, it has a flavor resembling green apple sorbet, and many Amazon customers note that, while it still has an earthy taste, it's more tolerable than most greens powders they've tried—with only 1 gram of sugar.

For the price, you get an excellent value of nutrients. While KOS Show Me the Greens doesn't have the novel's-worth of ingredients of more expensive greens powders, it still packs in a note-worthy amount of nutrients worth your attention, including the antioxidant spirulina and the nutrient-dense algae chlorella.

Our only qualm with KOS Show Me the Greens is the use of proprietary blends, which, while keeping the brand's unique formula top secret from competitors, also keeps users in the dark about the exact amount of each ingredient that they're getting. Still, most consumers highlight positive health changes after using KOS Show Me the Greens for anywhere from a few days to weeks; these include improved energy levels, less bloating and feeling cleansed or detoxified.

Pros:

  • Budget-friendly
  • No artificial sweeteners, preservatives or coloring
  • Non-GMO, vegan, certified organic
  • Good price point compared to other products on our list

Cons:

  • Some users complained of feeling nauseous after taking on an empty stomach
  • Smaller dosage compared to other products on our list

  • Sugar/sweetener: None
  • Dose: 1 scoop (12 grams)

  • Taste & texture: Earthy, citrusy flavor (similar to pineapples); mixes easily, but needs to be shaken up after sitting

AG1 is an all-in-one greens powder designed with a comprehensive formula for overall health support.

AG1 is full of vitamins including B complex vitamins like thiamine, folate and biotin in addition to CoQ10, an antioxidant that supports cardiovascular health. You’ll also get a serving of vitamins C, E and A plus calcium and selenium among others to help support thyroid function and your immune system.

Sprout Living’s Epic Protein Green Kingdom could be used for a morning smoothie or post-workout shake since it contains protein to help rebuild muscle tissue. This protein powder contains no additional flavoring, thickeners or fillers and includes some superfood properties, too.

We chose this organic plant protein and superfood blend as the best greens powder with protein because it's free of gums, additives, gluten, soy and dairy and comes in Chocolate Maca, Vanilla Lucuma, Original and Green Kingdom flavors. Green Kingdom features hints of ginger and citrus as well as hearty servings of spirulina, kale and moringa (a plant packed with tons of vitamin C and potassium).

We chose Country Farms Collagen + Greens as the best greens powder with collagen because it's derived from 100 percent pasture-raised and grass-fed cattle and features a mushroom blend. Collagen is a protein that is found in connective tissue, skin, tendons, bones and cartilage. Consuming collagen may help improve the health of your skin, hair and nails. 

This powder also contains a greens blend that can help your energy levels as well as aid in boosting your immunity. Country Farms packed several nourishing ingredients into this greens powder including superfoods such as kale, flax seeds, chlorella and ten different types of mushrooms in addition to featuring type I and type III collagen peptides (which help support skin elasticity and amino acid production).

Collagen + Greens is unflavored and free of gluten and sugar as well as being non-GMO. You can blend it in with coffee, water or even your daily smoothie. Some users note that although this greens powder is labeled as unflavored, they still get an earthy taste. One reviewer mentions adding Collagen + Greens to chocolate milk to mask the flavor while others don’t mind it.

Several reviewers mention feeling more energized after consuming Collagen + Greens and one user notes that it has helped curb sugar cravings in addition to noticing less hair fallout and clearer skin.

Pros:

  • Contains collagen for skin, hair and nail health
  • Fairly inexpensive

What Is a Greens Powder?

Greens powders are powdered supplements containing whole fruits, green vegetables, herbs, prebiotics, probiotics and digestive enzymes among other ingredients. Most products are a simple scoop in an eight to 10-ounce cup of water. That’s all that it takes to effectively consume a large dose of micronutrients that can provide you with a slew of health benefits.

What Are the Health Benefits of Greens Powder?

Greens powders offer the same benefit as a multivitamin—they're an insurance policy to fill in any deficiencies in micronutrients that you may have in your diet. Most greens powders offer the benefits of promoting gut health, supporting immunity and boosting energy levels. Prebiotic fiber and probiotics are great for gut health. Prebiotic fiber can be found in foods such as beans, asparagus and legumes. These foods actually feed probiotics, which are the good bacteria found in your stomach. And vegetables and fruits, which are key ingredients in a powdered greens supplement, provide you with energy and support your immune system. Common ingredients include spinach, kale, broccoli and wheat grass.

What Should I Look for When Buying Powdered Greens?

Your intent

Many powdered greens offer similar ingredients and claims. I suggest that you first ask yourself why you think you want to take a greens product. Do you follow a healthy diet or could you be lacking nutrients? Check to see that you will be getting a variety of nutrients from your powder. “Many greens powders also include digestive enzymes and probiotics, which can be helpful for individuals struggling with gut issues,” Oswald says.

Doses

Keep an eye on the actual doses, and you may start to notice some products may be underdosed and not the best value. Look for supplements that have transparent labels (watch out for proprietary blends), so you know exactly how much of each ingredient you're getting per serving.

Ingredient quality

Opt for products that source their nutrients from organic whole foods. It's even better if a brand shares where they source their ingredients from. Even if a brand claims they have the "best superfood powder" on the front of the package, read the nutrition facts and ingredients list to make sure you aren't getting just a couple of low-dose ingredients.

Third-party testing

Be sure to look into whether or not the party is third-party tested and has any certifications. Since the supplement industry is not regulated by the FDA, it is important to find a company that goes the extra mile to prove that their products contain what they claim and at the proper dosages.

“Third-party testing ensures that what the brand is claiming is in the product is actually in there. Third-party testing also tests for harmful contaminants,” says Nadeau.

Who Should Take Greens Powders?

  • Greens powders are a great option for those who do not consume as many fruits and vegetables as they should. In a way, they're like a super multivitamin that has other benefits. 
  • Greens powders also benefit busy parents or professionals who are always on the go and may struggle to eat enough nutrient-dense whole foods. You can pack a shaker bottle with a scoop of greens and put a water bottle in your bag and you are set to start your day off right.
  • Athletes may also benefit from a greens powder as their dietary requirements may be higher than a sedentary person, although they'll need to make sure their greens powder doesn't contain any ingredients that are banned from competitive sports.
  • Someone might need a greens powder if they are not able to eat or absorb enough of these nutrients from their food, Oswald says.
  • Those with diseases that affect nutrient absorption can benefit from the high levels of concentrated nutrients in greens powder, though they should check to make sure no ingredients will cause additional GI issues.

Who Should Not Take Greens Powders?

  • People who are on medications that include blood thinners, cholesterol-lowering medication, antacids or seizure-controlling medication may have a contradiction with the high levels of vitamin K found in greens powders.
  • Pregnant women may need to steer clear of greens powders as prebiotics, probiotics and digestive enzyme levels may be too high combined with prenatal vitamins. Alfalfa is a common ingredient in greens powders that may also counteract pregnant women as well as anyone with an autoimmune disease. 
  • Those who eat a balanced diet full of colorful fruits and vegetables, lean proteins and healthy carbohydrates should get enough nutrients from their food, and may not need the extra nutrients from a greens powder.
  • Additionally, those who already take a multivitamin or mineral supplement should consult their doctor to make sure they aren't consuming too much of any particular nutrient.

Greens Powder Safety: What to Know Before You Start a Greens Powder Supplement

Generally, greens powders are designed to be good for you by providing essential vitamins and nutrients. It's important to note that greens powders shouldn't be used to replace whole foods completely.

“Even if you try a greens powder, I still recommend trying to add more whole-form fruits and veggies to your diet,” says Nadeau. “Luckily most greens powders are unlikely to do harm.”

However, you should consult with a healthcare provider, nutritionist or registered dietitian to discuss whether or not a greens powder is a good fit for your diet, current medication schedule and lifestyle.

Greens Powder FAQs

Is consuming greens powder daily good for you?

A daily greens powder can be good for you if you are the type that does not like to consume many fruits and vegetables throughout the day. If you already eat a ton of fruits and veggies, then you may not benefit from a greens powder as much.

Do greens help you lose weight?

Greens are not necessarily a direct weight loss supplement but there are some key features that may help you on your weight loss journey. Most will feel tired and lethargic while dieting due to a lack of calories. Greens supplements can provide you with more energy thus helping you carry on with your progress.

Can too many greens be harmful?

Leafy greens are rich in vitamin K which is fat-soluble and can become toxic if too much is consumed. It is important to stick to the recommended dose of each greens product, according to Trista Best, MPH, RD, LDN, a registered dietitian at the Whitfield County Health Department in Dalton, GA. Excessive vitamin K can also act as a blood thickener which may cause complications for those on blood thinner medication. Please consult with your physician on whether or not a greens powder is right for you especially if you are on medications.

Do greens powders replace vegetables?

You should treat greens powders as dietary supplements, not total replacements for whole foods like fruits and vegetables.

“For someone who isn't eating a lot of fruits and vegetables, it can certainly be helpful to fill in nutrient gaps that you're not getting otherwise,” Nadeau says. “But, you can fill those nutrient gaps by adding more whole fruits and vegetables to your diet. In fact, if you're someone who isn't eating enough fruits and vegetables, I highly recommend turning to whole foods first.”

Are greens powders healthy?

Greens powders can be a healthy addition to your diet but it is important to understand that a supplement is just one part of a person’s nutrition and dietary habits. A balanced lifestyle with a healthy diet and regular physical activity are also important factors for general health and well-being.

“For some people, they may also help with digestion because many brands are packed with prebiotics and probiotics,” says Nadeau. ”Another benefit of greens powder is simply that it feels like a healthy habit. Starting your day with a big glass of ‘greens’ can often set the tone to continue with healthy habits for the day. If it gives you a boost in the morning and helps you to make healthier decisions throughout the day, that's a huge benefit," she adds.

Are greens powders FDA-approved?

The FDA (U.S. Food and Drug Administration) does not regulate the supplement industry. This is why it is paramount to search for a product that is third-party tested and allows customers to view the testing results.

It‘s also important to note that greens supplements haven't been researched enough to back most claims with science. “There is certainly some potentially promising research on greens powders, but more needs to be done. Plus, most research that does exist has been done by greens powders companies,” Nedeau says.

Do greens powders help with inflammation?

Greens powders may help with inflammation, but the research is still unclear. Some studies have shown antioxidants such as vitamin C, selenium, vitamin A, beta carotene, lycopene and vitamin E can help fight inflammation.

What is spirulina and what does it do?

Spirulina is a blue-green algae that is safe for consumption by humans and is considered a nutritional superfood. It contains phycocyanin which is a powerful plant-based protein that reportedly offers several benefits including: anti-inflammatory effects as an antioxidant, heart health support by helping to lower cholesterol and triglyceride levels and allergy relief and immune system support by boosting the production of white blood cells.

Should I keep my greens powder in my fridge?

It is not necessary to keep greens powders in a fridge; typically, you can store powder in a cool and dry place such as a kitchen cabinet or pantry. Unless a greens powder specifically states that it needs to be stored in a refrigerator, it should be fine if left unrefrigerated.

How long does it take for greens powder to start working?

This varies from individual to individual based on numerous factors such as a person’s health, diet and lifestyle. Some people could see improvements in a few days and some may need a few weeks before they feel or notice a difference. You can help improve the efficacy of a greens supplement by taking exactly it as directed but remember that it may take some time for your body to adjust.

Are all green powders the same?

While it may seem that many green powders have the same basic ingredients, it is important to pay attention to the amounts of the individual ingredients. There are certain thresholds that are recommended for a nutrient to be effective. It is also important to look for a certification such as NSF Certified for Sport to ensure that the supplement is tested to contain an accurate amount of ingredients claimed by the manufacturer.
