L-Lysine Info
Amino Profile:
Lysine is an essential amino acid. This means that the human body cannot produce L-Lysine and this important amino acid must be obtained from dietary intake.
Use in the Body:
L-Lysine is a necessary building block for all protein in the body. L-Lysine plays a major role in calcium absorption; building muscle protein; recovering from surgery or sports injuries; and the body’s production of hormones, enzymes, and antibodies. Lysine appears to help the body absorb and conserve calcium. Lysine has many functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes. For years, lysine has been considered in the treatment of herpes and cold sores, and more recently, has been attracting attention as a possible addition to the fast-growing list of muscle-building nutrients.
Supplement Usage:
Brewer’s yeast, legumes, dairy, fish, and meat all contain significant amounts of lysine. Most people, including vegans (vegetarians who also avoid dairy and eggs), consume adequate amounts of lysine. Athletes involved in frequent vigorous exercise have an increased need for essential amino acids. Taking normal amounts of Lysine, no consistent problems have been reported in humans, though abdominal cramps and transient diarrhea have occasionally been reported at very high intakes of 15 – 40 grams.
Lysine supplementation has been shown to increase the absorption of calcium and it may reduce its excretion. Lysine works with other essential amino acids to maintain growth, lean body mass, and the body’s store of nitrogen.
