L-Nutra is a company centered around longevity and healthy aging. Decades of research have led to the creation of nutrition technologies, programs, and foods that support a healthy life.


The company is most known for their ProLon® 5-day fasting-mimicking (FMD) nutrition program, carefully researched and developed to give you the benefits of prolonged fasting, while still providing food and nourishing your body with specific nutrients that won’t activate your food sensing radars. The ProLon 5-day program focuses on natural, plant-based, gluten-free, and low glycemic index ingredients.


ProLon products are designed around L-Nutra’s patented FMD longevity formulations to support healthy aging, cellular rejuvenation, metabolic balance, weight loss, lean muscle maintenance, improved relationships with food and more.


L-Nutra Health offers medically supervised metabolic health programs designed to prevent, regress, and remit type 2 diabetes without drugs. The programs are centered on L-Nutra’s patented FMD nutrition solution, originally funded by the NIH.
