Lysine is recognized as an amino acid necessary as a building block for all proteins in your body. It plays a major role in calcium absorption, as well as in helping building muscle protein. Besides, Lysine aids in recovering from surgery or traumas and helps your body produce hormones, enzymes, and antibodies. This amino acid was also proved to depress the central nervous system while having antiseizure properties.

Lysine is an essential amino acid, implying that it is important for human health, though our body cannot produce it. Therefore, it has to be obtained from food. Lysine is a type of amino acids that are the building blocks of proteins. It is vital for proper growth and plays an important role in the production of carnitine, which is a nutrient that transforms fatty acids into energy and lowers cholesterol levels. In addition, this amino acid is proved to help the human body absorb calcium, while playing an essential role in the formation of collagen - a substance necessary for both bones and connective tissues like skin, cartilage, and tendon.

Naturally, people obtain enough Lysine from foods, but athletes, vegans, and people who do not like beans may need more. A lack of Lysine in the body can cause such symptoms as slow growth, fatigue, nausea, dizziness, and even reproductive disorders. Vegans are recommended to consume more legumes like beans, peas, and lentils to obtain enough Lysine.

Benefits of Lysine
There are numerous studies proving that Lysine may help prevent outbreaks of cold sores and genital herpes. Other studies revealed that it helps the body absorb calcium and decrease the amount of calcium lost in urine. Since calcium is essential for bone health, you can conclude that Lysine may help prevent the bone loss caused by osteoporosis.
