The science behind longevity and medical nutrition therapy

L-Nutra's Fasting Mimicking Diet (FMD) was created by Dr. Valter Longo and developed with the Longevity Institute at USC, building on 25+ years of his research, backed by more than $36 million in National Institutes of Health and European Union funding. It is the subject of 41 human clinical trials, completed and ongoing.

 

Our research spans 42 collaborations with universities, medical centers, and research institutes, including Stanford, Mayo Clinic, Cedars-Sinai, Charité Berlin, and Leiden University Medical Center. A 2025 randomized pilot trial found that the FMD increased autophagic flux, a marker of cellular renewal, in human immune cells.

 
We publish our research in peer-reviewed journals (61 so far), so it can be tested, built on and brought into mainstream care. Browse the studies below.
