The Active Ingredient Is: Acetyl L-Carnitine

Acetyl L-Carnitine is a naturally occurring amino acid derivative that plays a role in mitochondrial energy production and cognitive function support. This form is commonly used to help with cellular energy metabolism and neurotransmitter synthesis.

This form is typically derived from acetylation processes and is present in various tissues, including the brain, where it may support energy utilisation and nerve function.

What Does Acetyl L-Carnitine Do?

Acetyl L-Carnitine helps mitochondrial energy production by transporting fatty acids into mitochondria for fuel, aided by its role in supporting acetylcholine synthesis, a neurotransmitter involved in memory and focus. Scientific research suggests these mechanisms may contribute to cellular energy and cognitive vitality, in line with EFSA observations.

The primary benefit is enhanced cellular energy and cognitive vitality, supported by the combination with Alpha-Lipoic Acid which acts as an antioxidant and supports metabolic processes.
