Acetyl L-Carnitine
Acetyl-L-Carnitine also known as MRM, Methylationand. ALCAR is a natural remedy super antioxidant, occurring form of L-Carnitine that specifically benefits the brain. ALCAR helps supply the brain with energy by improving energetics in the mitochondrion, the cell's energy generator. ALCAR promotes biosynthesis of acetylcholine, a key neurotransmitter for brain and nerve function. Acetyl-L-Carnitine has been shown in clinical studies to benefit cognitive ability, memory and mood.
Acetyl-L-Carnitine is an amino acid the body uses to turn fat into energy. It is not normally considered an essential nutrient because the body can manufacture all it needs. However, supplemental Carnitine may improve the ability of certain tissues to produce energy. This effect has led to the use of Carnitine in various muscle diseases as well as heart conditions.
