They better change the recommended intake of Niacin then. Without being able to read the full article, I am interested in what they constitute as "excess niacin". There have been studies on the consumption on energy drinks namely Redbull, given that they have added Niacinamide. The recommended daily intake of Niacin is 16mg for Men, with an upper tolerable limit of 35mg. A single can of Redbull 250ml has 20mg of Niacinamide.
