L-Lysine is an essential amino acid that supports immune function, collagen production, and calcium absorption. It is crucial for the synthesis of carnitine, which helps convert fatty acids into energy, making it beneficial for athletes and active individuals. L-Lysine also plays a role in the production of enzymes, hormones, and antibodies.
This amino acid is particularly known for its potential to support skin health and reduce the frequency of cold sores caused by the herpes simplex virus. It is often included in supplements aimed at promoting overall wellness and recovery.
While L-Lysine is generally safe, excessive intake may lead to gastrointestinal issues or kidney stress. It is important to balance L-Lysine intake with other amino acids to avoid potential imbalances.
