The Active Ingredient Is: Acetyl-L-Carnitine (Acetyl-L-Carnitine Hydrochloride)

Acetyl-L-Carnitine is basically an acetylated cousin of L-carnitine, a compound involved in energy metabolism and nerve support, often linked with cognitive function as we age.

This variant is acetyl-L-carnitine hydrochloride and comes in a vegetarian capsule. The product is made to quality standards aligned with GMP and ISO 9001:2008 practices, reflecting high-purity ingredients and controlled production methods.

What Does Acetyl-L-Carnitine Do?

EFSA-aligned information suggests this nutrient helps with acetylcholine synthesis and supports energy production in tissues with high energy needs, including the brain and nerves.
