iHerb Customer Reviews

Best value for money for a Vitamin C.

Posted by iHerb Customer on Feb 02, 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.

Thanks for your feedback!

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

Thanks for your feedback!

Unmissable For The Body

Posted by iHerb Customer on Jan 13, 2018 | Verified Purchase

For allergies, for avoid flu, for make it shorter, for gums, for collagen forming... I personally feel i can’t go without it. It makes me be ok. And when I don’t have it I feel the consequences. Important is to never miss it, ‘cause body gets used to it and you can create a sudden scurvy situation if you suddenly stop taking your C. What I like from Doctors best is that is non GMO (no other ascorbic acid states that)

Thanks for your feedback!
