Lysine Supplements
Lysine is a type of amino acid that would reduce the duration of a cold sore outbreak. While more scientific evidence is necessary, several studies have suggested that this substance would interfere with how amino acid arginine is absorbed in the intestine. As the herpes virus requires this element to multiply, lysine can be helpful in reducing the risk of outbreaks. You can apply it topically or take a supplement. Both forms are available at pharmacies without a prescription. Do not take lysine supplements over a long period as it may lead to some side effects. Also, make sure to follow the instructions and take the right dosages to prevent stomach pain or diarrhea. [2]
