Niacin 3.7 5 3 3
A nice alternative supplement and a good price. August 21, 2013
Not niacin The material in these containers is not niacin. It's is probably also not niacinamide. It is most likely just chalk. It is labeled niacin. October 20, 2012
I like it! This has helped me greatly. For me taking this 250 mg Niacin twice a day is a lot easier to take than it is to take 500 mg once a day. I like taking it after lunch and dinner. In my way of thinking, that is when it does me the most good. It's a good product which I am confident to recommend to anyone. January 8, 2011
