From Vitamin B3 To Nad
N macro- and micronutrients is the basis for health and well-being. One of these supplements, vitamin B 3 , is known to be effective against pellagra, a disease caused by malnutrition. Lately, some preparations of vitamin B 3 have garnered huge attention for their seeming ability to counteract symptoms of metabolic disease and ageing decline in preclinical studies.
From VITAMIN B 3 TO NAD
Vitamin B 3 comprises a group of molecules that can act as precursors for the classical enzyme cofactor nicotinamide adenine dinucleotide (NAD), which consists of nicotinic acid (NA), nicotinamide (NAM) and the more recently discovered nicotinamide mononucleotide (NMN)2 and nicotinamide riboside (NR).3 NAD is a central mediator of cellular energy metabolism and a crucial link between nutritional intake, cellular metabolism and health. There are several routes to synthesise NAD. Individuals with vitamin B 6 deficiency are not able to sufficiently metabolise Trp,4 pointing to the importance of a well-balanced diet with adequate amounts of necessary micronutrients.
They are very efficient at increasing NAD levels in many tissues, while circumventing the undesirable side effects of NAM and NA.
Potential Benefits
However, it’s unclear whether it would have the same effect in humans and how strong this effect really is Nicotinamide riboside helped speed up the metabolism of mice.
May lower cancer risk: High NAD+ levels help protect against DNA damage and oxidative stress, which are linked to cancer development May promote healthy muscle aging: Raising NAD+ levels helped improve muscle function, strength and endurance in older mice Potential Risks and Side Effects Nicotinamide riboside is likely safe with few — if any — side effects.
However, most human studies are short in duration and have very few participants. For a more accurate idea of its safety, more robust human studies are needed. Some people have reported mild to moderate side effects, such as nausea, fatigue, headaches, diarrhea, stomach discomfort and indigestion In animals, taking 300 mg per kg of body weight (136 mg per pound) daily for 90 days had no harmful effects What’s more, unlike vitamin B3 (niacin) supplements, nicotinamide riboside should not cause facial flushing Dosage and Recommendations Nicotinamide riboside is available in tablet or capsule form and is commonly called niagen.
It is available at select health-food stores, on Amazon or through online retailers. Niagen supplements typically contain just nicotinamide riboside, but some manufacturers combine it with other ingredients like Pterostilbene, which is a polyphenol — an antioxidant that is chemically similar to resveratrol Most niagen supplement brands recommend taking 250–300 mg per day, the equivalent of 1–2 capsules per day depending on the brand.
Summary Most niagen manufacturers recommend taking 250–300 mg of nicotinamide riboside per day.

Health and disease is of increased interest as the use of niacin (nicotinic acid) has emerged as a major therapy for treatment of hyperlipidemias and with the recognition that nicotinamide can protect tissues and NAD(+) metabolism in a variety of disease states, including ischemia/reperfusion. In addition, a growing body of evidence supports the view that NAD(+) metabolism regulates important biological effects, including lifespan.
Nad(+) exerts potent effects through the poly(ADP-ribose) polymerases, mono-ADP-ribosyltransferases, and the recently characterized sirtuin enzymes. These enzymes catalyze protein modifications, such as ADP-ribosylation and deacetylation, leading to changes in protein function. This review considers current knowledge of NAD(+) metabolism in humans and microbes, including new insights into mechanisms that regulate NAD(+) biosynthetic pathways, current use of nicotinamide and nicotinic acid as pharmacological agents, and opportunities for drug design that are directed at modulation of NAD(+) biosynthesis for treatment of human disorders and infection.
Trends In Food Science & Technology
Orm of cellular nicotinamide adenine dinucleotide (NAD+) is implicated in longevity, health improvement and even attenuation of some neurodegenerative processes. Scope and approach Moderate by-effects, like flushing, may have limited supplementation with some B3 precursors so far. Here we review the safety data on the vitamin B3 precursors as supplement.
