Doctors Best Quali C

Posted by iHerb Customer on March 11 2018 | Verified Purchase

Very high quality product. I usually swallow 2 caps on an empty stomach when I get the scratchy throat syndrome or the ahem bug and it zaps them within an hour. It does not seem to work as well on a full stomach. I will be buying this for a long time. Highly recommended

Thanks for your feedback!
