- Vitamin Supplement
Niacinamide, also known as vitamin B-3, functions in over 50 metabolic reactions, most of which are enzymatic. Its bioactive forms - NAD+, NADH, NADP, and NADPH - play important roles as catalysts in the energy production process in the cells, the breakdown of proteins and fatty acids, the synthesis of fatty acids, and the formation of steroid hormones and red blood cells. Source Naturals Niacinamide is prepared to provide a gradual release over a prolonged period of time.
1 tablet daily.

iHerb Customer Reviews
A Word About “Time-Released” Supplements To make it easier to take high doses of niacinamide, a few companies have come out with time-released niacinamide products. The problem with these time-released products is that they can possibly cause liver problems, so you would need to get periodic tests to monitor liver function. I don’t recommend taking these products. Taking straight niacinamide in smaller doses throughout the day has never caused any liver problems or other side effects. Apparently, the carefully balanced blood levels allow both the liver and the kidneys to deal with the higher levels of niacinamide.
I bought this because I don't like taking niacinamide every 3 hrs.I take 500mg for RH and it really works but I sometimes forget to take it or am busy.This I only have to take 3 times per day and it works almost as well.Nothing works better.

Taking half tablet with breakfast seems to help our old knees - taken with a multi-vitamin.
Good,, but large tablet

This product seems to be effective but it is a VERY large tablet and difficult to swallow. I break it in pieces which may effect the time release.
Har tro på denne

Fikk anbefalt å ta store doser av vitamin B3 og har gjort det over en lang tid nå. Merker bedre energi, men sammen med B12 og D3 som jeg også tar store doser av
