Lysine, also known as L-lysine, is an important amino acid that your body needs for healthy growth and development of body tissues. Lysine is essential for production of collagen, the primary building block of the cartilage, tendons, bones and skin. Lysine is also required for absorbing calcium from foods. It is involved in production of the amino acid carnitine. Deficiency of lysine causes lethargy, loss of appetite, anemia, irritation, dizziness and nausea. Depletion of the lysine reserve of the body causes stunted growth in children and fertility problems in adults. Insufficient intake of lysine rich foods causes deficiency of this important nutrient.
