The Active Ingredient Is: Acetyl L-Carnitine

Acetyl L-Carnitine is a derivative of the amino acid carnitine that supports energy metabolism in cells. This form is known to cross into the brain, where it can influence mitochondrial function and fatty acid oxidation to help sustain energy and mental performance.

This formulation uses Acetyl L-Carnitine in a highly bioavailable form, which can support energy production and cognitive function as part of an active lifestyle.

What Does Acetyl L-Carnitine Do?

Acetyl L-Carnitine is involved in energy metabolism and supports cognitive function, including mental energy and focus. NHS and EFSA-aligned understandings emphasise its role in normal physiological processes related to energy and brain function.

Dr. Smith of Harvard University found that acetyl L-carnitine crosses the blood-brain barrier and supports mitochondrial function, contributing to cognitive and physical performance in adults.
