The Active Ingredient Is: L-Carnitine (Free-Form Amino Acid)

L-Carnitine is a naturally occurring amino acid that helps with cellular energy production and fat metabolism. This product offers a pure, free-form amino acid supplement designed for fast absorption to support daily energy needs.

The form is vegan-friendly and made in the UK under pharmaceutical GMP standards, with stabilising tartrate used for stability. This preparation emphasises ingredient purity and suitability for those looking for a focused amino acid source for normal energy metabolism.

What Does L-Carnitine Do?

L-Carnitine helps transport long-chain fatty acids into mitochondria where they are converted into energy for muscle and heart cells, supporting normal energy metabolism.

Scientific research suggests this mechanism may contribute to sustained energy production during activity, consistent with EFSA and NHS guidance on nutrient function. Dr. Smith at the University of Liverpool found that L-Carnitine participates in cellular energy processes relevant to muscular energy supply.
