Our Story

Precision nutrition for health and longevity.

Tailored to reverse and slow down biological age (through our 5-Day and daily nutrition), Prolon Nutritional products are discovered and licensed from the Longevity Institute of the University of Southern California and 18 other university research institutions. Food is the only product we consume every day of our lives. It was time for ethical science, instead of for-profit business, to develop nutrition formulations aimed at enhancing human health and supporting medicine. 

The Longevity Diet Book summarizes the main discoveries behind Nutrition for Longevity and Food as Medicine.
