L-Nutra and Parsley Health announced a strategic partnership to broaden access to nutrition-based interventions for metabolic conditions, according to the company. Under the alliance, patients of Parsley Health will gain access to L-Nutra’s Prolon® product suite, including the Prolon 5-Day Program, L-Protein, and Fasting Bars, via Parsley’s online store.
Parsley’s clinical team—comprising more than 80 board-certified physicians, nurses, and health coaches—has been trained in L-Nutra’s clinical programs and will incorporate them into individualized care plans. The programs are structured to support goals such as reduced reliance on medications, lower HbA1c levels, fat-focused weight loss while preserving lean muscle, and improved glycemic control via food-led, personalized care.
L-Nutra claims its innovations are grounded in decades of clinical research and patented nutrition protocols, with more than 130 patents and over 47 clinical trials conducted in partnership with global research institutions. Parsley Health offers a digital-first platform and operates centers in New York City and Los Angeles, providing care under a root-cause, personalized medicine model.
The companies present this collaboration as a model for embedding advanced nutrition science into routine medical practice to address the escalating prevalence of metabolic dysfunction and type 2 diabetes.
