Prolon is the only nutrition program patented for its nutrition biotechnology that promotes longevity and healthspan while protecting lean body mass. Prolon has unlocked nutrition science that provides the benefits of an extended water fast while still allowing food and nourishment. Backed by over 25+ years of rigorous research, Prolon stands as the top doctor-recommended Fasting Mimicking Diet (FMD). After its three-month onboarding period, experts advise following the program three times annually (only 15 days of your year) for optimal benefits.

The nutrition biotechnology of the Fasting Mimicking Diet (FMD) is at the core of the extensive health benefits of Prolon products. The precise nutrition formulations within the elements of the 5-Day program provide the maximum calories and macronutrient ratios while still maintaining a fasted state. This allows the body to stay nourished, protects the muscles from degradation, and optimizes the cells and metabolism. Its products are entirely plant-based and clean. Prolon is the only Fasting Mimicking Diet (FMD) and was developed at the Longevity Institute of the University of Southern California and at L-Nutra Inc. by a global team of Longevity experts led by Professor Valter Longo (TIME Top 50 Most Influential People in Health).
