ATP Science Acetyl L-Carnitine

Acetyl L-Carnitine is a naturally occurring derivative of the amino acid L-Carnitine that plays a critical role in cellular energy metabolism. In the body, it facilitates the transport of long-chain fatty acids across the mitochondrial membrane, where they are converted into ATP. This fat-shuttling function is central to how cells derive energy from lipid sources.

Compared to plain L-Carnitine, the acetylated form offers improved solubility and may cross the blood–brain barrier more readily, supporting nerve and neurotransmitter pathways. As a result, it’s often chosen when both metabolic and cognitive support are desired. Available in powder or capsule form, Acetyl L-Carnitine provides a versatile way to supplement your routine with a compound that underpins fatty-acid utilization and contributes to overall mitochondrial function.

For best results take 2 grams before, during, or directly after training. Don’t let the smell turn you off, the right amount mixed into water only has a slightly bitter taste, like lemon water or powdered vinegar. Get on it – don’t be a sook!
