5 out of 5 stars review

Real Niacin!

This is a comfortable dose of niacin and even though it's a tablet, it has a slick finish that doesn't stick in my throat when swallowing. Dosage seems very consistent per tab, which speaks well for the quality of this brand. Attractively priced, this one is a keeper!

great product

I was looking for Niacin as a cholesterol reducer. These give just the right amount of "flush," which is needed to be beneficial.
