Thank you Natural Factors - no unnecessary fillers or ingredients
Posted by Health-Is-Wealth on Oct 24, 2013
Effective! I've started to look at Natural Factors more and more - often good value and/or don't contain lots of unnecessary junk. These tablets are small and well utilised - can easily be cut in half if needed (e.g. to avoid a niacin flush) and hold together well. Would prefer a 50mg tablet. Recommend.

hard to find!

I have been using this for some time after reading Andrew Saul's Doctor Yourself books. I have to split them in half to not get an overwhelming niacin flush reaction. But it's a good way to see if you're short niacin or not. No flush, you're short, take more later. Flush, you're doing fine. It's a good buy, too!

Excellent price, good dosage amount, ingredient is only Niacin, which is difficult to find.
Just experienced my first flush
Posted by Reviewer2329940 on Oct 11, 2011
I started taking these about a week ago, and had not experienced any flushing until about three days ago...I work in a very cold office :( so the flushing was a welcomed feeling.

This did cause a flush (I was aware of) which from my understanding is a good thing because it helps to eliminate toxins.

I always test the potency of any niacin supplement by taking it on empty stomach with juice in the morning. this brand pass the test with flying colors. the flushing is rapid and quite intense. plus there are no other unnecessary ingredients in it. recommend to all.
Trying out for high cholesterol
Posted by Reviewer2000421 on Jan 26, 2010
Trying to see if it help high cholesterol. So far can feel it thins my blood which is good. So I take 50 mg (half a pill) every other day to avoid too much thinning of blood.
Niacin in its pure form without any additional unneeded ingredients

Bought this after listening to numerous lectures by Andrew Saul. Seems to be the only "original" niacin on iherb without any unneeded and harmful ingredient.

I use the natural niacin to lower high blood pressure and cholesterol. It works great for both and I don't mind the flush it gives as it is healthier and works better than the flush-free kind.
