Liosin

Liosin is a supplement containing L-lysine, an essential amino acid your body needs to build proteins. It's often used to support immune function, improve skin health, and reduce cold sore outbreaks caused by the herpes simplex virus. Since your body can’t produce L-lysine on its own, it must be obtained from food or supplements. People take Liosin to help maintain overall health or to manage specific conditions like cold sores, though scientific evidence varies regarding its effectiveness. Always consult a healthcare professional before starting any new supplement.
