for anxiety and depression

Posted by iHerb Customer on Jan 17, 2014 | Verified Purchase

I recommend niacinamide to my patients for anxiety and depression, it works, Dr Abram Hoffer found mid last century the power of Vit B3 in mental health. Need 1000 mg to 4000 mg daily in divided doses.

Thanks for your feedback!

Timed release niacinamide

Posted by iHerb Customer on Dec 08, 2013 | Verified Purchase

This is a good brand, and I think these have worked well. However, I didn't notice when I ordered that these are timed-release, and for my purpose, I will go back and look for 1000 mg option that is not.

Thanks for your feedback!
