Amino acids are building blocks of protein, and lysine is one of them. This is one of the 9 essential amino acids that are produced by the body. Lysine helps in proper calcium absorption and creation of collagen. It’s also vital in carnitine production, which is a nutrient that helps lower the level of cholesterol and turn fatty acids to energy. This amino acid is also used in treating herpes. The recommended daily intake or RDI of lysine is 13.6 mg per pound or 30 mg per kilogram of the total body weight.
