Made a difference

Posted by iHerb Customer on March 13 2018 | Verified Purchase

I often fall sick, as frequently as once a month. But after incorporating this vitamin c into my daily routine, I've fallen sick less often, maybe once every 2 or 3 months. There were many times when I felt a sore throat or fever coming, but it always went away after I take my daily dose, no kidding. This is my 2nd bottle and I see no reason to stop!

Best value for money for a Vitamin C.

Posted by iHerb Customer on February 2 2018 | Verified Purchase

This vitamin C is really good. It does not have a lot of filler like most brands. Plus it's friendly to my stomach. It's not too acidic. My immune system is good when taking this Vitamin C. Rarely I catch a cold or a flu. The pills were a bit too big but I already used to swallow big pills. Overall it's a really good Vitamin C especially for a 1000mg per capsule. A great value for money from a trusted brand like Doctor's Best.

Unsure how much is absorbed without doing the studies on myself, however I like to have it on board anyway , Good price.
