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

Acetyl-L-Carnitine is a mitochondrial energy supporter used in capsules to aid cellular energy production and metabolic function.

This form includes the acetyl group, allowing for brain access and supporting acetylcholine synthesis, with vegan, non-GMO and gluten-free sourcing where stated.

What Does Acetyl-L-Carnitine Do?

Scientific research suggests it helps transport fatty acids into mitochondria for energy production and plays a role in neurotransmitter formation that supports neural communication.

This mechanism aligns with recognised nutrient functions involved in energy metabolism and brain function.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
