Two running mice
Scientists from Mayo Clinic have significantly extended lifespan in male mice by inhibiting the enzyme CD38, which lowers NAD levels [1]. The age-related decline of nicotinamide dinucleotide (NAD) has been associated with various metabolic abnormalities, age-related diseases, and fitness loss. Nicotinamide Adenine DinucleotideNicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. It...
White Blood Cells
A study published in the Nature journal Aging and Mechanisms of Disease has shown that supplementation with nicotinamide riboside (NR) substantially improves the immune systems of older mice due to its effects on stem cell fate. However, the benefits do not persist after NR is removed. The destiny of blood cells As the researchers explain,...
Brad Stanfield Interview
In this interview with Steve Hill of Lifespan.io, Dr. Brad Stanfield discusses the various forms of niacin along with NAD+ boosters such as NR and NMN, and he touches upon supplements, rapamycin, and other facets of the longevity world. Brad is very active in the community and runs the successful Dr. Brad Stanfield Youtube channel....
NR molecule
Nicotinamide riboside (NR) is part of the B3 vitamin family. Like other forms of vitamin B3, nicotinamide riboside gets converted into nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for life. For this reason, it is often called a NAD+ precursor because it is part of the series of chemical steps that are required to create...
Diagram of NADH
What is NAD+? Nicotinamide adenine dinucleotide (NAD+) is a key coenzyme found in all living cells. It is a dinucleotide, which means that it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base, and the other contains nicotinamide. NAD+ is essential for life, one of the most versatile molecules...
Blood cells
Researchers have reversed the age-related decline in the function of hematopoietic stem cells (HSCs) in older mice using nicotinamide riboside. This success can make our blood more youthful and increase the effectiveness of stem cell transplantation [1]. There will be blood HSCs are the progenitors of all our blood cells. HSCs reside in the bone...
