What Prolon does

Prolon is the consumer longevity nutrition brand of L-Nutra Inc., a privately held US company headquartered in Culver City, California, founded by Dr. Valter Longo of the USC Longevity Institute. The company sells a precision nutrition platform built around the Fasting Mimicking Diet (FMD), a patented 5-day plant-based meal protocol designed to trigger cellular renewal through autophagy while keeping the body below key nutrient-sensing pathways (mTOR, IGF-1, PKA).

The company operates primarily as a direct-to-consumer e-commerce business through prolonlife.com, with a separate practitioner portal (l-nutraprofessional.com) enabling healthcare professionals to recommend products to patients. Prolon targets health-conscious consumers focused on longevity and healthy aging, weight management seekers, intermittent fasting practitioners, and clinicians seeking evidence-based nutritional tools. Customer segments are served through a hybrid distribution approach that combines DTC subscription and one-time purchases with healthcare professional referrals.

The business is supported by a substantial scientific evidence base: 25+ years of foundational research, 47 clinical trials, 41+ peer-reviewed publications, 130+ global patents, $48M+ cumulative R&D investment, and partnerships with 18 leading research institutions including USC, Stanford, Mayo Clinic, Cedars-Sinai, and UT Health San Antonio.
