Acetyl-L-Carnitine 250 mg Vegetable Capsules (Free Form)
Our daily protein requirement is really a need for amino acids. Dietary amino acids are classified as "essential" or "non-essential". Essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine) cannot be manufactured by the body and must be supplied in the diet or ill-health results. The non-essential amino acids are also essential for health but can be synthesised in the body from the essential amino acids. Both the essential and non-essential amin acids are reassembled as hormones, enzymes, neurotransmitters (chemical messengers), antibodies and nutrient carriers.
