NAD (ß-Nicotinamide Adenine Dinucleotide) is the biologically usable form of niacin (vitamin B-3). NAD is present in all living cells as a cofactor for many biochemical reactions, playing a central role in cellular energy production. Thus, the more NAD available to the cell, the more energy it can produce. NAD and its reduced form, NADH, are readily converted by the body, but unlike NADH, NAD is not altered by the acids present in the stomach.

Excellent Quality

Posted by healthandlongevity on Dec 27, 2013

Very good product. It's effects subjectively are very subtle, but on the cellular level are profound. NAD (product of Nicotinamide) shows serious promises in the field of life-extention and delay of cellular senescence.

The Missing Cofactor

Posted by Reviewer2167095 on Nov 10, 2012

After many years of illness I recently had a urinary amino acid test performed by Genova Diagnostics. There were many abnormal results (high in the red) indicating impaired metabolism of those amino acids. There was only one necessary cofactor that all of these amino acids shared in common & that is NAD. It turns out I am not making enough NAD from niacin to properly metabolise these amino acids. Taking this NAD supplement has literally switched me back on. This is the first NAD I have tried & will also try NADH to compare.
