It does not say so clearly on the bottle- but this is time released niacin which could cause LIVER DAMAGE!!!! I prefer to take the regular fast-acting niacin which does not have those side effects!!!!

I'm switching to another brand, because this sometimes gives me a flush that itches and looks like hives (for about half an hour).

I take this without food and so I do feel a slight flush which feels good to me.

A good vitamin, although on the packaging state that it is flush-free, I can still feel the flushing of my skin. But other than that it is good to have everyday.

Nice to take B6 without going red in the process.

This is just a basic niacin. The tablets are reasonably small, which is nice.

Great product, but I chewed it up and got some unpleasant flush... Recommend eating whole.

No flushing here, seems fine. However time will tell as to if its making any difference. No side effects. All OK.

Took me a while to work out that the rapid onset, short duration, blotchy pink/red, raised, prickly rash across my face, neck, shoulders and upper arms was from the Niacin. It only lasts about 1/2 hour but is a little uncomfortable and doesn't look too attractive. When I don't take the Niacin for a while, there is no flushing. Withing days of recommencing, these random rashes reappear at will though not every day.

This isn't flush free - I get a definite flush from it, sometimes quite pronounced.
