The Active Ingredient Is: L-Carnitine

L-Carnitine is a molecule involved in energy metabolism by ferrying long-chain fatty acids into mitochondria for energy generation.

This ready-to-drink liquid formula delivers L-Carnitine in a handy form to support muscle energy workflows during workouts.

What Does L-Carnitine Do?

L-Carnitine participates in fatty acid transport into mitochondria, helping to generate ATP during physical activity. Dr. Pooyandjoo of Tehran University found that L-Carnitine supplementation can aid exercise performance and fat oxidation. This aligns with the role of energy metabolism in sustaining normal activity levels.

This section explains how the nutrient functions in normal body processes and supports energy production during routine physical activity.
