Prolonged Release Niacin is rated 3.7 out of 5 by 3.
Rated 5 out of 5 by from A nice alternative supplement and a good price.

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from 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.
