Easy to consume

With non-acid vitamins, you also can consume it anytime even before the meal or during the day.

Strong, has bioflavenoids, and is non-GMO

Posted by philosophicalcat on April 6 2018 | Verified Purchase

I regularly take high doses of vitamin C to combat the oxidizing stress of smoking. I`m happy to find a product that supplies a large dose and has the bioflavonoids and co-factors that help the body to utilize the vitamin C. There is some controversy about whether ascorbic acid is the complete form of vitamin C, or if it is simply the "envelope" for the co-factors and all must be taken together to work properly. I`ve found that high doses of simple ascorbic acid sometimes causes scurvy-like symptoms: bruising and bleeding gums. If I take extra bioflavonoids, the condition stops. So, I prefer a form that already has the co-factors included, and also take extra of the co-factors. I take 2,000 mg at a time, which is the "safe upper limit," because higher doses often result in diarhea. I find that it depends on the state of your health whether more than 2,000 mg will trigger diarrhea; when I`m sick (with a cold, for example), I can take more. In this case, I think the "safe upper limit" is more likely to be the "safe convenient limit," since your body gets rid of whatever it can`t handle but I don`t think there is any harm. "Safe" seems to be too strong. I can take 2,000 mg every four hours if I`m battling a cold and be perfectly fine. However, it`s best to use a buffered type of vitamin C like this one; otherwise, too much ascorbic acid will disturb the lining of the stomach. I`ve been using this brand and strength of vitamin C for years.

very large pills

Posted by iHerb Customer on March 20 2018 | Verified Purchase

These are too big to safely swallow in my opinion.

Thanks for your feedback!

I wanted a stronger vitamin C which these are but I discovered the tablets are quite large and not always so easy to swallow. I’ll probably stick with the capsules next time as they’re easier to swallow.
