The Active Ingredient Is: L-Carnitine

L-Carnitine is an amino acid derivative that plays a pivotal role in normal energy metabolism. In its free form, it participates in transporting fatty acids into cellular powerhouses to support energy production during activity.

This form is the active nutrient responsible for lipid metabolism and is derived from natural biochemical pathways involving methionine and lysine, supporting the body’s ongoing energy management processes.

What Does L-Carnitine Do?

L-Carnitine is involved in transporting long-chain fatty acids into mitochondria where they undergo beta-oxidation to generate energy. It may support fat metabolism and endurance aspects of physical activity, aligning with recognised energy metabolism roles in EFSA/EU guidance.

Alongside other nutrients, this ingredient helps the body optimise energy production during exercise and may contribute to body composition goals through its role in fatty acid utilisation.
