The creator of Fasting Mimicking Technology - Dr. Valter Longo, Ph.D
Dr. Valter Longo, Director of the Longevity Institute at the University of Southern California, was recognized by TIME as one of the top 50 most influential people in health. As the pioneering mind behind the Fasting Mimicking Diet, Dr. Longo was awarded the first-ever patent for Healthspan. His groundbreaking work revealed how cells sense nutrients, leading him to develop the FMD formulation. Through extensive mouse and human trials, he demonstrated the powerful benefits of this approach. These discoveries are the foundation of our Prolon product line, designed to bring the science of healthy aging to you.
