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!
Thank you Natural Factors - no unnecessary fillers or ingredients

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.

Excellent price, good dosage amount, ingredient is only Niacin, which is difficult to find.
Just experienced my first flush

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.

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.
Feel the flush

Feel the flush on and off, therefore feel the product must be working in my body.
The real deal

This Niacin is what I expected incl. the flushing.But when you eat something at forehand you don't have the flush.I take the tablets after each meal.That makes a total of 300 mg. I take it in combination with B complex and L-Glutamine powder. 2,5 month no alcohol graving any more and my cholesterol is much better. Al I can say: Give it a try!

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

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.
