L-lysine for shingles
If you’re among the growing number of Americans affected by shingles, you may decide to take L-lysine supplements, a long-standing natural remedy.
Lysine is a naturally occurring building block for protein. This makes it a necessary part of a balanced diet. L-lysine refers to the dietary supplement. It’s thought that L-lysine can help relieve cold sores.
Herpes simplex virus type 1 (HSV-1) causes cold sores. HSV-1 is under the same umbrella of viruses as the virus that causes shingles. This virus is called the varicella-zoster virus. It’s the same virus that causes chickenpox.
After a bout of chickenpox, this virus is dormant in the body. The virus can then reemerge, usually years later, as shingles.
While L-lysine is said to relieve cold sores, there’s no evidence to support its treatment of shingles.

What are the benefits of L-lysine?

A L-lysine regimen may prevent or reduce the occurrence of cold sores. If you already have a cold sore, L-lysine may help the sore heal more quickly.
The protein-building amino acid may also aid in digestion. It’s said to help your gastrointestinal tract absorb calcium. This added calcium can contribute to new bone tissue.
Your body doesn’t produce lysine, so you must consume it through the foods you eat. If your diet is lacking in lysine, you may have a compromised immune system. You may also develop higher levels of stress and anxiety. One 2004 study found that a diet rich in lysine can reduce these levels.
