Powerzone Nutrition Acetyl-L-Carnitine (ALC) is the biologically active form of the amino acid L-Carnitine. ALC occurs naturally in the body and it plays an important role in the production of acetylcholine, one of the body's key neurotransmitters. But one of the most important roles of ALC is the transport of fats into mitochondria (the powerhouses of the cells) where most of the cell's energy is produced. ALCAR has been studied extensively and found to have significant anti-ageing and cognitive benefits. Several clinical trials suggest it can be effective in improving memory, mood and response to stress. ALCAR is a cognitive enhancer and neuroprotective agent that protects against a wide range of age-related degenerative changes in the brain and nervous system.
