L-Lysine Benefits and Side Effects
L-Lysine Benefits and Side Effects
Lysine is one of eight essential amino acids – building blocks of protein – that the body cannot manufacture on its own. L-lysine is a specific configuration of the lysine molecule often used in dietary supplements.
As a building block of protein, l-lysine benefits the body by contributing to growth.
L-lysine benefits also include production of carnitine, a substance that converts fatty acids into energy and lowers levels of LDL (“bad cholesterol”) in the bloodstream.
In addition, l-lysine benefits the skeletal system by contributing to the production of collagen, the protein used to make bone, tendons, cartilage and connective tissue. Calcium absorption and use is also facilitated by this supplement, which also benefits the skin by helping to maintain its health and elasticity.
Without enough lysine in the diet, a range of health conditions may result. Though most people can easily obtain sufficient amounts of this critical amino acid through diet, those who eat large amounts of sugary cereals and baked good may minimize l-lysine benefits.
This is because lysine is involved in the browning of sugar, which occurs when the two substances bind together. As a result, it is difficult for the body to absorb the lysine in sugary foods. So, in cases where a person’s diet is high in foods that contain a lot of simple sugars, supplements may be of use.
There may be other l-lysine benefits from supplements for people with specific health concerns.
