ProLon’s revolutionary Fasting Mimicking Nutrition Technology delivers the transformative power of fasting without complete food deprivation. Developed through decades of research at the Longevity Institute of the University of Southern California, this precision nutrition formulation nourishes the body while keeping metabolic processes in fasting mode. Unlike traditional fasting, it provides essential nutrients while triggering cellular rejuvenation and metabolic reset. Backed by over 32 clinical trials at leading research institutions, including Stanford, Mayo Clinic, and the University of Miami, ProLon’s fasting programme supports longevity, enhances metabolic health, and promotes overall wellbeing.
ProLon is redefining the science of fasting with cutting-edge nutrition designed to support long-term health. Founded by Dr. Valter Longo, a world-renowned longevity expert and Director of the Longevity Institute at USC, the brand emerged from a mission to harness the power of fasting for disease prevention and cellular renewal. Through over 20 years of scientific research, ProLon continues to pioneer the field of longevity-focused nutrition, making fasting more accessible while advancing the concept of food as medicine.

Enjoy a simple approach to fasting with Prolon Reset 1.
1. Use as a full-day nutrition kit whenever you want to support your fasting routine.
2. Add to your weekly schedule once or twice a week to help maintain healthy habits.
3. Ideal for use with intermittent fasting (such as the 5:2 Diet).
Intermittent fasting (IF) involves alternating between periods of eating and fasting. The 5:2 Diet, for example, means eating normally for five days and following a fasting routine for two non-consecutive days each week. Prolon Reset 1 is designed to fit seamlessly into this approach, providing balanced nutrition on your fasting days.
