I always get this brand! I trust it, it works. Both my husband and I take it. It's very good for those with some anxiety. This with Vitamin C is the perfect match. I only take UP TO 3 per day. It's not the flush free kind of Niacin. It's not Niacin, but Niacinamide - doesn't flush ever. - Tamara Jack
