The best form is NMN, which stands for nicotinamide mononucleotide, a molecule naturally occurring in all life forms. At the molecular level, it is a ribo-nucleotide, which is a basic structural unit of the nucleic acid RNA. Structurally, the molecule is composed of a nicotinamide group, a ribose and a phosphate group. NMN is the direct precursor of the essential molecule nicotinamide adenine dinucleotide (NAD+) and is considered a key component to increase NAD+ levels in cells.

What is Nicotinamide Adenine Dinucleotide (NAD+)?
NAD+ is an essential coenzyme required for life and cellular functions. Enzymes are catalysts that make biochemical reactions possible. Coenzymes are ‘helper’ molecules that enzymes need in order to function.

What Does NAD+ Do?
NAD+ is the most abundant molecule in the body besides water, and without it, an organism would die. NAD+ is used by many proteins throughout the body, such as the sirtuins, which repair damaged DNA. It is also important for mitochondria, which are the powerhouses of the cell and generate the chemical energy that our bodies use.

NAD+ Functions as a Coenzyme in Mitochondria
NAD+ plays an especially active role in metabolic processes, such as glycolysis, the TCA Cycle (AKA Krebs Cycle or Citric Acid cycle), and the electron transport chain, which occurs in our mitochondria and is how we obtain cellular energy.

In its role as a ligand,
NAD+ binds to enzymes and transfers electrons between molecules. Electrons are the atomic basis for cellular energy and by transferring them from one molecule to the next, NAD+ acts through a cellular mechanism similar to recharging a battery. A battery is depleted when electrons are expended to provide energy. Those electrons can’t return to their starting point without a boost. In cells,

NAD+ serves as that booster.
In this way, NAD+ can decrease or increase enzyme activity, gene expression, and cell signaling. NAD+ Helps Control DNA DamageAs organisms grow older, they accrue DNA damage due to environmental factors such as radiation, pollution, and imprecise DNA replication. According to the current aging theory, the accumulation of DNA damage is the main cause of aging. Almost all cells contain the ‘molecular machinery’ to repair this damage. This machinery consumes NAD+ and energy molecules. Therefore, excessive DNA damage can drain valuable cellular resources.

One important DNA repair protein, PARP (Poly (ADP-ribose) polymerase), depends on NAD+ to function. Older individuals experience decreased levels of NAD+. The accumulation of DNA damage as a result of the normal aging process leads to increased PARP, which causes decreased NAD+ concentration. This depletion is exacerbated by any further DNA damage in the mitochondria.

Immune System
As adults get older the immune system declines, people get ill more easily, and it becomes harder for people to bounce back from illnesses such as the seasonal flu, or even COVID-19. Recent studies have suggested that NAD+ levels play an important role in regulating inflammation and cell survival during the immune response and aging. The study underscored the therapeutic potential of NAD+ for immune dysfunction.

Leading cardiologist, Dr Ross Walker, who I heard a couple of years ago recommended the taking of NAD+ as a potential anti-aging therapy. He himself is taking NAD+ or other forms such as MNM.

You are correct Shikari, your levels of NAD+ decrease dramatically with age and that is primarily what causes aging
I've noticed since taking MNM that my hair colour is changing to near normal again plus other important things as well.
