My life saver!

The effects for me have been nothing short of miraculous. It's the only thing I use anymore. At first I didn't think much of it because i thought i wasn't that sick and didn't feel much difference. But when i stopped taking it I realized that it was why I was feeling better. Now mind you, I don't get sick often and i take no other medication regularly- maybe that has something to do with it.

Yes, I recommend this product
