L-Lysine supplements are a dietary addition that aim to provide immune support for individuals. These supplements contain an essential amino acid that the body cannot produce on its own, meaning it must be obtained through diet or supplementation. L-Lysine has been shown to help the body produce antibodies, enzymes, and hormones that contribute to a healthy immune system. Additionally, L-Lysine may help reduce the severity and duration of cold sores caused by the herpes simplex virus. These supplements are widely available and come in various forms, including capsules, tablets, and powders.
