When blood levels dropped below this level, cold sore breakouts increased 4. Though this study is promising, it did not state the amount of lysine or other ingredients used in the cream 1. Furthermore, not all studies show that lysine is effective in reducing cold sore occurrence or duration. One review found insufficient evidence to recommend it for treating cold sores 5.

Lysine may play a role in reducing anxiety. One study found that it blocked receptors involved in stress response.

However, the women who also received mg of lysine lost less calcium through their urine Lysine appears to protect your bones and may also play a part in controlling whereto calcium is transported in your body. For example, it has been shown to prevent the buildup of calcium in blood vessels in rats.
This kind of buildup is a risk factor for heart disease Furthermore, one test-tube study found that cells that were grown without lysine had an increased movement of calcium out of the cell. This increase did not occur in the cells that had lysine present Summary Lysine may help you absorb more calcium and reduce the loss of calcium in your urine.
It could even reduce the risk of calcium buildup in your blood vessels. In animal tissue, lysine becomes more active at the site of a wound and helps speed up the repair process Lysine is required for the formation of collagen , a protein that acts as a scaffold and helps support and give structure to skin and bones Lysine itself may also act as a binding agent, thereby increasing the number of new cells at a wound.
