The Active Ingredient Is: L-Carnitine (base)

L-Carnitine is a nutrient that helps transport long-chain fatty acids into the mitochondria where they are used to produce cellular energy.

This formulation uses a vegetarian L-Carnitine base and includes calcium as an excipient to support the overall product structure.

What Does L-Carnitine Do?

L-Carnitine contributes to fat metabolism by enabling fatty acids to enter energy-producing pathways, supporting energy production during activity. Scientific research suggests this can aid in exercise recovery and fat utilisation; NHS and EFSA recognise energy metabolism as a normal function of these nutrients.

Dr. Pooyandjoo of University of Tehran found that L-Carnitine can improve fat metabolism and support exercise recovery in adults.
