NMN seems to be the most efficient form of B3 for this purpose.

A little about Niacin. 

WHAT IS IT?

Niacin is one of 8 water-soluble vitamins.  Its number is B3.  And because it's water-soluble, it means that your body does not store it.  You get Niacin through food.  One notable source of niacin is tryptophan which can be found in turkey and other animal meats.  

Its key role is in the formation of NAD and NADP, which help your body process components from food into usable energy.  

Your body can make Niacin through tryptophan.  

Why take Niacin?

One, we need it.  It's a B vitamin, B3, that improves circulation in all vessels--arteries, veins, capillaries, arterioles, et al.  The circulation improves the skin and the health of organs.  

We may not know it, but we take Niacin to increase the NAD, nicotinamide adenine dinucleotide (NAD), the active coenzyme form of vitamin B3, involved in most of the body's essential functions.  NAD helps boost energy, improve mental clarity, and promote a youthful appearance.

It's the NAD that we're all after.  That's where the anti-aging magic occurs.

The Qyral Team explains that,

You can take NMN, niacinamide, or even niacin, which are small enough to get into your cells, break down, and convert into NAD+ naturally. NMN seems to be the most efficient form of B3 for this purpose.

The Qyral Team says,

Niacin is good for helping cholesterol levels.  It raises HDL (good cholesterol) and lowers LDL (bad cholesterol) levels.  One downside is that it causes skin flushing and rashes in some people.  It is generally  harmless, but not everyone likes the effect. 

Some food sources of Niacin are: 

Niacin is found in both plant and animal foods. Lean red meat, poultry, and liver contain high levels of both niacin and tryptophan and, together with legumes, are important sources of the vitamin. Peanut butter is an excellent source of niacin. Cheese and eggs are relatively poor sources of preformed niacin, but these high-protein foods contain ample amounts of tryptophan and therefore have a high niacin equivalent. Fruits and vegetables provide useful amounts, depending upon the dietary intake. Other useful sources are whole grain cereals, bread, tea, and coffee. Predominantly in maize and other cereals, vitamin occurs in an unabsorbable form called niacytin. The milling of cereals removes most of the niacin since it is concentrated in the aleurone and germ layers. 

Coffee, raw peanuts, and Cornflakes contain the highest sources of niacin in food. 

Niacinamide is also a form of vitamin B3, but it’s slightly different from niacin.  Niacinamide is the vitamin B3 that you get from meat and poultry.  In other words, it comes from animal-based foods.  

Many grain products are also fortified with it.  You can take NMN, niacinamide, or even niacin, which are small enough to get into your cells, break down, and convert into NAD+ naturally. NMN seems to be the most efficient form of B3 for this purpose.

NAD+ is also required for sirtuins to do their thing.  Sirtuins are proteins that help us live longer and can help us stay thin.  Learn more about sirtuins in this blog post.  

Niacin is a major component of NAD and NADP, two coenzymes involved in cellular metabolism.  NMN plays a role in producing NAD+ and NADP.

NMN can increase muscle function in older men. 

NMN has anti-aging properties because it helps our bodies produce NAD+.  NAD+ (NICOTINAMIDE ADENINE DINUCLEOTIDE) IS THE STUFF WE WANT.  

Qyral Team explains that,

All of these forms of B3 have benefits, but NAD+ is what we ultimately want.  Your cells need NAD to function.  It’s a molecule that helps your body turn food into energy.  You need that energy for moving and thinking, which slow down as you age.  Healthy cells mean your body can more easily repair itself.
