Where did you hear about that? You only take the B12 once you feel symptoms?
I did a lot of research when my Mother was suffering. Sent her the included info. She was cleared up in about 72 hours and never had another outbreak. When my daughter had an outbreak I sent her the same info and hers cleared up in less than 2 days. I’m a believer.
The info:
TAKE:
L-Lysine - clobbers the herpes zoster virus and props up the immune system.
Vitamin D3 boosts your immune system, wards off viruses.
When you have an outbreak, take 6000-8000 milligrams of L-Lysine a day. Also up your dose of Vitamin D to 4000 milligrams.
The first time I had shingles, the Dr gave me a B12 shot. Cured within days. However, shingles remains in the body and can cause infrequent pains. I don't get them often, but if I don't take a B12, the pains will continue.
