Top 10 functions of L-lysine in the human body

The complex biochemistry of the human body demands hundreds and thousands of chemicals for proper body functioning. The L-lysine, an essential amino acid is a similar chemical that promotes body function when obtained in the right amount from the food sources or supplements. As it is an essential amino acid, it is not produced by the body. The functions that it plays in the human body include the following:

1. Essential for child’s growth

There are tons of metabolic processes going on in the body. L-lysine supports the diabetic patients by inhibiting the production of advanced glycation end products. This helps in lowering the risk of infections and helps the body stay away from other diabetes complications.

4. Treats herpes disease

According to British Society for Antimicrobial Chemotherapy, a study proved that L-lysine supplements have an anti-viral effect that helps in treating viral diseases like the herpes infection. The cold sores, mouth and genital blisters, as well as, pain can be reduced by its use.

5. Produces carnitine

L-lysine helps in producing carnitine but what is carnitine and how does it help the body? This element is found in all the body cells and it participates in generating energy from fatty acids. Sufficient amount of lysine in the body keeps it active and fatigue-free.

6. Heals Osteoarthritis

The function mentioned in point number ten – improved calcium absorption, helps in treating osteoarthritis. It helps in preventing bone loss that occurs in this joint degenerative disease. Along L-arginine, Lysine promotes the bone-building cells in the body and enhances bone growth.

7. Reduces acne outbreaks

No direct studies are present to prove the function of lysine in improving acne but many patients are in its favor. They say that the frequency of acne outbreaks reduces with L-lysine supplements. As collagen plays an important role in supporting and repairing the skin, the supplement promotes collagen formation which in return benefits the skin.

8. Boosts athletic performance

The evidence stated in the journal named Current Medical Research and Opinion talks about eight times increase in the growth hormone in the body by taking L-Lysine. This hormone boosts the body’s athletic performance, increases muscle mass, and reduces fatigue by rapid muscular healing.

9. Relieves stress

The animal protein like red meat, eggs, and fatty fish are rich sources of this nutrient. A study shows that sufficient intake of the foods containing L-lysine helps the body fight stressful situations.

10. Improves calcium absorption

It is seen that L-lysine promotes calcium absorption from the digestive tract. As calcium is important for healthy bones, dental and muscle health, the supplement proves beneficial. It also helps in fighting cancer, reducing PMS symptoms and gaining weight.
