Excellent ingredients and could feel the difference within a week of taking the pills whereby I interacted with some persons who have flu but, luckily nothing wrong happened to me. I believe my immunity system is much stronger now
I used to buy Frontier Stinging Nettle leaf to get the benefits. The downside was that it stained my teeth, badly. Now I can get the benefits of Stinging Nettle and keep my teeth white. The staining was so bad that it took the hygienist extra time to clean my teeth. Once I realized what was causing the problem, I haven't had any more staining on my teeth.
