Years ago scientists from a major patent medicine company published an article about niacinamide research in animals. They compared niacinamide to the patent medicines Valium and Librium and found their activities were much the same.

Niacinamide is very effective for improving the mood, attitude, and mental clarity of those with type 2 diabetes or insulin resistance/metabolic syndrome. Some users also report that their thinking… or their head… is much clearer when using niacinamide.

I take only 500 mg once in the morning and feel better within a couple of hours. At night I take 1,500 because of its sedative effect in higher doses.
