What is NECTAR7 Niagen?

NECTAR7 delivers Niagen which is the first commercially available form of Nicotinamide Riboside (NR), offered in a capsule. The following is a step by step guide to get you learning.
What is Nicotinamide Riboside?
Niagen is Nicotinamide Riboside (or NR, a version of vitamin B3). By itself, Nicotinamide Riboside is not very useful. But once inside your body, it binds with proteins to create an enzyme known as nicotinamide adenine dinucleotide, or NAD+. Just remember this — “NR is a precursor to NAD+”
What is NAD+?
NAD+ can help mitochondria (the powerhouse inside your cells) generate energy and improve communication between other cells. In 2013 when a study conducted at Harvard University discovered that “raising NAD+ levels in old mice restored mitochondrial function to that of a young mouse.” More specifically, the tissue of the mice decreased in age significantly. And, “In human years, this would be like a 60-year-old converting to a 20-year-old in these specific areas.” Not so exciting until you read the next study completed by Dr. Charles Brenner.
What did Dr. Charles Brenner show the world?
Dr. Charles Brenner, a Biochemistry Professor at the University of Iowa Carver College of Medicine, recently completed a human clinical study showing a single dose of Niagen® increased NAD+ levels in human blood up to 2.7 times.

The NAD+ metabolomics analyses were performed in the laboratory of Dr. Charles Brenner, the Roy J. Carver Chair of Biochemistry and Professor of Internal Medicine at the University of Iowa. Dr. Charles Brenner, who was then a faculty member at Dartmouth College, discovered NR to be a vital precursor of NAD+, which is made available by nicotinamide riboside kinases (Nrks) that are conserved between yeast and humans. In 2007, Dr. Charles Brenner’s lab discovered a second pathway by which NR is converted to NAD+ and showed that NR can extend the lifespan of yeast cells by virtue of elevating NAD+ levels and increasing the activity of the NAD+-dependent Sir2 enzyme.
