Not flush free!

I have always been sensitive to niacin and I mistook sustained release for a no flush type niacin. This stuff made me flush sometimes five hours after taking it. If you are sensitive to niacin, make sure you get a flush free brand like Spring Valley. I am sure Now is a good brand, and I use some of their other products but this one just doesn't work for me.

Caused Flushing On Me

This caused me flushing, that progressed to almost whole body, I won't be taking it anymore.

Now Niacin 500 mg - 250 Tablets per bottle

Great value for 2 bottles of Niacin (250 Tablets per bottle) from a brand that I trust. The sustained release makes it so there is almost no flushing. Does a good job for helping lower my cholesterol as well.
