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.

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!

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.
