The Active Ingredient Is: L-Carnitine (Fumarate Form)

L-Carnitine is an amino acid-like compound that plays a role in fat metabolism and energy production within cells. This formulation uses fumarate to support cellular energy pathways. The product employs Biosint Carnitines to provide a vegan, high-purity form of L-Carnitine fumarate.

This form is designed to be vegan and non-GMO, with a pharmaceutical-grade production process that emphasises purity and safety.

What Does L-Carnitine Do?

L-Carnitine participates in transporting long-chain fatty acids into mitochondria, where they can be used to generate energy. Fumarate functions as an intermediate in the Krebs cycle, contributing to cellular energy production. Dr. Stephens of the University notes these roles in energy metabolism.

EFSA-aligned understanding recognises energy metabolism and mitochondrial function as central to normal physiology.
