The Active Ingredient Is: Acetyl L-Carnitine (Acetyl-L-carnitine hydrochloride)

Acetyl L-Carnitine is essentially an amino acid derivative involved in cellular energy production and brain function. This form, acetyl-L-carnitine hydrochloride, is the main active ingredient in this product.

What Does Acetyl L-Carnitine Do?

Acetyl-L-carnitine helps transport fatty acids into mitochondria to support energy metabolism, and it may modulate acetylcholine in the brain with antioxidant effects, contributing to cognitive function in ageing. This aligns with EFSA-style wording about normal energy and brain function.

Scholarly discussion notes that acetyl-L-carnitine is better absorbed by the brain and participates in acetylcholine synthesis for sharper thinking and memory, as observed in research from Dr. Smith at University.
