Where longevity meets medical support


L-Nutra Health is the medical division of L-Nutra, Prolon’s parent company.

How it works

L-Nutra Health programs go beyond symptom management by addressing the underlying causes of metabolic conditions—such as muscle loss, abdominal fat, and cellular aging. Through clinically validated, dietitian-guided comprehensive programs centered around cycles of a low-glycemic FMD, L-Nutra Health programs offer a proactive solution for prevention, management, remission, and even reversal.
