Lysine is found in great quantities in muscle tissues, stimulates calcium absorption, carnitine synthesis, and growth and repair of muscle tissue. In diabetics, it can increase insulin sensitivity and decrease blood sugar levels. Excessive supplementation can add to the total-body nitrogen load, challenging ammonia clearance and leading to kidney problems.
Lysine is a component of structural proteins and enzymes in the body. Transamination of amino acids requires lysine as an ”anchor” point for coenzyme pyridoxal phoshate. Some individuals who exhibit symptoms of B-6 deficiency actually have a lysine deficiency that limits functional B-6 activity. Lysine is abundant in animal source proteins and legumes, but is often deficient in vegetarian diets that are based on corn, rice and cereal grains. Symptoms commonly associated with lysine deficiency include poor appetite, muscle weakness/poor muscle tone, weight loss, anemia, and poor dream recall.
Although rare, high levels may be due to lysine supplementation or impaired metabolism of lysine. Add vitamin C, niacin, vitamin B6, α-ketoglutarate and iron to enhance utilization of lysine.
