Prolon

Prolon UK sells 5-day fasting-mimicking meal kits (£189–£199 per cycle) and single-item “Fast Bars” (£29–£35 per box). All products are plant-based, shelf-stable, and portion-controlled to keep daily intake at ~770 kcal. Sales are online-only through prolon.co.uk; no retail presence. The brand is the consumer arm of L-Nutra, a nutrition company spun out of USC longevity research. Its patented Fasting Mimicking Diet (FMD) is clinically tested to trigger cellular clean-up and metabolic reset without total food abstinence. Each kit is pre-labelled by day to remove guesswork and is marketed as a quarterly “metabolic intervention” rather than everyday food. Core buyers are 30-55-year-old health-optimisers, biohackers, and time-poor professionals who want autophagy benefits without water-only fasting. They value data-backed wellness, measurable biomarkers, and the convenience of a ready-to-follow protocol. Prolon competes in the premium “scientific wellness” niche against DIY fasting apps, juice-cleanse brands, and subscription nutrition programmes. It differentiates with peer-reviewed studies, medical-grade formulation, and a positioning that frames fasting as a temporary, clinically validated tool rather than a lifestyle diet.
