Overview

NOW Acetyl-L-Carnitine (ALCAR) provides 500mg per capsule of the acetylated form of L-carnitine that crosses the blood-brain barrier. Unlike regular L-carnitine (which primarily supports fat metabolism), ALCAR specifically supports brain energy production by transporting fatty acids into mitochondria within brain cells. Research supports ALCAR for cognitive function, mood, neuroprotection, and age-related cognitive decline. The 200-capsule count provides exceptional value.
