What is L-Lysine?

L-Lysine, or simply lysine, is one of the body’s eight essential amino acids. It does not appear naturally and is not produced in the human body, therefore, L-Lysine has to be taken into the digestive system through food sources or L-Lysine dietary supplements. 1,2,3
L-Lysine is an amino acid essential for health by building protein and distributing calcium. It’s important for proper human bone and connective muscle tissue growth as well as playing a role essential in producing carnitine, a nutrient that converts fatty acids into energy. L-Lysine also helps the body form collagen that’s vital to skin health and production. A proper amount of L-Lysine is crucial in regulating cholesterol and triglycerides. 1,2,3
Most people who maintain a healthy and balanced natural diet have no need for L-Lysine supplements as their normal food sources contain ample amounts of L-Lysine. Deficiencies happen in people who have a protein lack or need additional L-Lysine for tissue repair. L-Lysine supplements are commonly taken by bodybuilders wanting to build muscle bulk, burn victims who need muscle tissue repair and vegetarians who do not consume protein-rich food. 2
Natural food sources that contain high amounts of L-Lysine are: 

  • Red meats, pork and poultry
  • Cheese and dairy products
  • Eggs
  • Nuts
  • Fish, especially sardines and cod
  • Beans, including all soy products
  • Spirulina
  • Fenugreek seeds
  • Brewer’s yeast

Aside from natural foods that are the best source of healthy L-Lysine intake, supplements are available in liquid, capsule, tablet and cream forms. 1
