iHerb Customer Reviews

So far so good

Posted by iHerb Customer on Aug 04, 2017 | Verified Purchase

My boyfriend has been taking Niacin for four years now and has tried a few different brands, both in stores and on line. So far he has been using this particular product for a week now and NO flushing which is a good thing, The only thing I would like from this product is offering it in 1000 mg. The price was good, I will reorder.

Thanks for your feedback!

I have been instructed to take this as it has been shown to lessen the frequency of skin cancers.

Bought these for my husband who takes them to help lower his cholesterol. He says they don't cause "flushing", a plus, but we're not sure how they'll affect his cholesterol numbers. Will post when we know.

Thanks for your feedback!
