Flush-Free Niacin 4.7 5 15 24
this flush free is the way to go 2 of my family members take niacin. Before trying this product, I had purchased an expensive time release niacin from the drug store that claimed it would not cause a reaction...huh! They were both bright red, hot, and very itchy. They also had some troubles with a couple of brands of so called flush free. I was nervous about trying another one, but they agreed to give this one a try. So far, so good. I am ordering another bottle because that one is almost gone. September 8, 2013
Affordable Flush Free Niacin Great product. My husband takes it and no flushing or hot reaction. Affordable also! June 5, 2013
Flush Free Niacin I am very happy with this product. I have not had any stomach upset and it truly is flush-free. I find this a great supplement to take in the evening to help with the sugar cravings! November 15, 2012
I much prefer the flush free niacin to the horrible hot, red, burning skin I got from regular 100-mg niacin. It is very effective, and I could sure tell the difference in my lab values when I stopped taking it for a while. I am always very pleased with the quality of Swanson's. October 22, 2012
Nice benefits I've been using flush-free niacin (inositol) for several years. I am impressed with sleeping better and my skin stays soft. These benefits keep this item on my shelf. September 8, 2012
Not what expected It states to take 3 caps a day with water and food. I did and it gave me a headache. So I cut down to two caps then one, but still getting a headache from both doses. Once I discontinued taking it, headache left. May 27, 2011
Flush-free Niacin This particular type of niacin doesn't cause me to flush but it also isn't effective for me like the regular type. January 21, 2011
good quality product. wish it had 1000 mg per capsule, that's why i just have 4 leaves for effectiveness & convenience, but other than that, great product! easy to swallow, too, despite being the 2nd biggest size SW-brand capsule. June 29, 2010
This does not upset your stomach and there is no flushing like it says. April 27, 2010
works well! Have tried other types of niacin that have made my husband really turn red. this niacin truly is an effective time-released formula. March 14, 2010
Niacin maintains normal blood pressure We have been using flush-free niacin for over 3 years to help keep blood pressure levels within the normal range. Nothing works better. August 12, 2009
no problems with this Niacin, in regard to the flush July 26, 2009
Best product I love Swanson Flush-Free Niacin. It has improved my health in so many ways. Its better than any other niacin I have used because it doesn't cause the flush that you would get with other niacin products. July 24, 2009
No hot stuff Does the job without the niacin flush. I use them to keep warm in the winter and have had excellent cholesterol numbers ever since I started the flush free version. No warm tingles but all the good effects March 26, 2008
No-Flush Helps support healthy lipid metabolism and energy metabolism without the flush. October 11, 2007
