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!!!!

Thanks for your feedback!

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

Thanks for your feedback!

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

Thanks for your feedback!

A must have for those with anxiety challenges

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.

Thanks for your feedback!

No flush

Nice to take B6 without going red in the process.

Thanks for your feedback!

A basic niacin

Posted by iHerb Customer on Apr 24, 2015 | Verified Purchase

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

Thanks for your feedback!

Don't chew!

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

Thanks for your feedback!

No Flushing here

Posted by iHerb Customer on Mar 27, 2017 | Verified Purchase

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

Thanks for your feedback!

Definitely a "flush"

Posted by iHerb Customer on Nov 20, 2012 | Verified Purchase

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.

Thanks for your feedback!

This does flush!

Posted by iHerb Customer on Sep 02, 2012 | Verified Purchase

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

Thanks for your feedback!
