Generalized Anxiety Disorder and Lysine

Read more about Lysine.

Overview

Lysine is an essential amino acid, one that you need to get from food. Some evidence suggests that supplemental lysine may be able to help some conditions including herpes infections and anxiety.

Effect of Lysine on Generalized Anxiety Disorder

Though the mechanism of action is unknown, Lysine when used in combination with Arginine might be useful for helping treat anxiety.

Research Evidence on Lysine

One study found that week-long oral treatment with lysine (2.64 g per day) and arginine (2.64 g per day) could reduce general levels of anxiety.57

Side Effects and Warnings

#Safety Issues

Although lysine is an essential part of the diet, the safety of concentrated lysine supplements has not been well studied. In animal studies, high dosages have caused gallstones and elevated cholesterol levels, ^[1] so you may want to use caution when using lysine if you have either of these problems. Maximum safe dosages for young children, pregnant or nursing women, or those with severe liver or kidney disease have not been established.

#Interactions You Should Know About

If you are taking lysine to treat herpes, arginine might counteract the potential benefit. ^[3]
