Straight niacin's flushing response can be bad enough, but take it for a couple of months and one day you will realize that your skin itches ALL THE TIME.

And the flush-free niacin will damage your liver over time.

I take 1500mg niacin a day (flushing type)....and my skin does not itch all the time....only when I miss a couple of doses, usually.
