Solgar L-Lysine 500mg Vegetable Capsules is part of the premium amino acid range. Amino acids are the building blocks of protein and are needed in several internal functions of the body. They are classified as \"essential\" or \"non-essential\", essential amino acids mean they cannot be manufactured by the body and must be supplied in the diet to maintain good all-round health. A suboptimal intake of the essential amino acids increases the body\'s need for the non-essential amino acids either through diet or supplementation. Foods that increase amino acid intake are meat, beans, cheese and eggs. L-Lysine is an essential amino acid and is found in the muscle tissue. It is also a supplement that is popular with people for seasonal support.
