Description: Lysine is an essential amino acid. A dietary source of lysine is
required since the body cannot make this amino acid.
Use: Lysine, like all amino acids, is needed to make various proteins used for
the maintenance, repair, and growth of body tissues.
- Lysine helps the body absorb calcium.
- Collagen, a protein that forms the basis of bone, cartilage, and connective
tissue, requires lysine for proper formation.
How much do I need? The minimum daily requirement of lysine for an average-size
adult (150 pounds) is approximately 800mg.
Is it safe? The risks of consuming large amounts of lysine are unclear, so
intake should be limited to no more than 3g. daily.
- In animals, high doses of lysine have been linked to an increased risk of
gallstones and elevated cholesterol levels.
What foods are good sources? As with all amino acids, excellent sources of
lysine include meat, poultry, fish, eggs, and dairy products.
