Is Lysine effective in preventing Shingles?

I take L-Lysine for cold sores and rarely have them, but when I do get one, I run to the Lysine. Recently I decided to take 500 mg of the L-Lysine/day in the hopes that it will keep me from ever having Shingles. Experimenting on myself, you might say. I cannot afford the shot for Shingles and I don't like taking that kind of stuff anyway. I don't take flu shots for the same reasons, I don't trust their content. I just work on keeping myself healthy. I am 68 yrs old.
Thank you for any ideas or advice or experience that you might have had or heard of on this subject. Mary

HI,
Thanks for writing in.
There are sporadic reports of use of L lysine supplementation for herpes prevention.But it is not approved and not proven to help in preventing herpes.
L-lysine is essential amino acid and supplement intake may help in general well being nevertheless.
Hope this helps.
