2Treat Cold Sores
Cold sores are often the sign of an infection by the HSV-1 virus on your mouth or lip. They are typically manifested as fluid-filled blisters that would lead to burning, pain, and tingling. Studies have shown that lysine supplements can help replicate and reduce the duration of cold sores. This effect is achieved as this component is able to block arginine, another form of amino acid that is needed for HSV-1 to thrive. When the lysine levels in your blood drop to a specific threshold, the frequency and intensity of cold sores tend to increase noticeably. However, you need to combine with many other factors to have a successful treatment. [2]
