Product Overview

  • 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.

Time-Released Supplements

Posted by Reviewer2624927 on Oct 18, 2012

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.

Good for what ails you

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.

Excellent for controlling cholesterol levels. Also brought the feeling back to my feet and toes. Great for blood flow.

The pill is huge. I guess it would be better if it had a split line in the middle, in order to be able to cut it in half for easy swalllowing.

Some natural reviews indicate this may prevent the onset of Alzheimers. This is correct item and strength at a good price.
