You get a really nice flush with these. After >1month still flush w/500mg/day. Good to manage cholesterol. Watch your liver if taking >1500mg/day.

Just be prepared for the Niacin Flush. The first couple of weeks of taking this I got a good healthy flush out of this every time. Problem is I did not know that B3 did this to a person. Turns out it is a very good thing. You should at least research "Niacin Flush" before you take it so you are not surprised or think you are having an allergic reaction. I am sure that a person might also look to see if it has any bad side effects, but I found nothing only good remarks about how wonderful it is for your health. I recommend this product.

Besides the strong flushing, it works good.

Definitely have a flush with these which is supposed to be a sign of it working. However the flush seems to be rather delayed in onset. Sometimes even hours later, sometimes no flush at all which makes me wonder if it is a result of the combination of other supplements taken at the same time or just some are dud.
