it was a special offer, so I decided to go for it, because normally I buy a larger size of a package . Any immunity boosters from this site work brilliantly I must admit. This one proves with and energy improvement as immunity benefits. Thank you iherb for bringing high quality supplements to the market.
I have been taking this supplement for many years, when the packaging was different. This supplement is awesome. In one pill, you get the main immune fighting vitamins and minerals in an easy to swallow pill. When I first took this pill, I was at the beginning stages of a cold. I notice in a few days, I felt better. I didn't take any other cold medication, just the Immune Boost. I have been taking them daily ever since.I haven't had a cold of any kind since I discovered these pills. If you want to give your body more protection on the inside, I absolutely recommend you try Natrol Immune Boost.
