The Active Ingredient Is: L-Carnitine Tartrate

L-Carnitine tartrate is an amino acid derivative that helps cellular energy metabolism by assisting the movement of fatty acids into mitochondria for energy generation. This form is a steady, bioavailable version commonly used in supplements to aid energy-related processes.

The main ingredient gives a base for normal energy metabolism, with the tartrate form helping in efficient utilisation of fats for energy inside cells.

What Does L-Carnitine Do?

L-Carnitine helps move fatty acids into mitochondria, enabling energy generation at the cellular level. This helps support normal energy metabolism and cellular function.

This might contribute to vascular health through nitric oxide-related pathways and support brain cell resilience in age-related cognitive contexts, aligning with widely recognised nutrient functions.
