Lysine Plus: What Patients Should Know Before Taking It
Lysine Plus is a dietary supplement that provides L-lysine, an amino acid the body uses to make proteins. It is marketed for general nutrition and sometimes for cold-sore prevention, wound healing, or bone support, although it does not cure an infection and evidence for some uses is limited. Products named “Lysine Plus” may contain additional ingredients, so check the package label for the exact formulation.
Lysine Plus is a supplement, not a prescription medicine, and there is no single dose suitable for everyone. Follow the product label and ask a doctor or pharmacist before using it, especially if you take other medicines or have medical conditions.
