What is Nicotinamide Riboside?

Nicotinamide riboside is a newly appreciated form of Vitamin B3, with unique properties, it is a formal precursor of NAD+.

Nicotinamide riboside (NR), first described in 1944 as a growth factor (Factor V) for Haemophilus influenza, and in 1951, NR, first investigated as a metabolic fate in mammalian tissues.

Famous patented Brand named NIAGEN®(Nicotinamide riboside chloride), released by Chromadex, Inc in 2003, aims to reverse signs of aging from inside your body.

This article will show you multi-faceted NR details; please continue reading the following:

What food sources of Nicotinamide Riboside?

The amounts of NR in food are minute, compared to a nutritional supplement, and what food sources contain nicotinamide riboside (NR)?

1.Cow milk

Cow milk usually have ∼12 μmol NAD(+) precursor vitamins/L, of which 60% was present as nicotinamide, and 40% was current as NR.(conventional milk contained more NR than organic milk ), a study published by the University of Iowa, in 2016

2.Yeast

An old study has stated, "One inhibitory substance was isolated from yeast and was found to be nicotinamide riboside, it may have from NAD(P) during the preparation of yeast extracts, or from dietary yeast supplements during digestion in vivo." While there is no quantitative data on yeast

3.Beer

The beer has a fair amount of carbs and drinking those in a liquid form like that will have a glycemic impact; various research papers have mentioned beer as being a food source of nicotinamide riboside.

Also, there may be trace amounts of NR like whey protein, mushrooms, etc.

For many people, dairy is off limits for other reasons. The nicotinamide riboside food sources might be useful, but are less efficient than an NR supplement.

Why Nicotinamide Riboside (NR) designate as an authentic NAD+ precursor vitamin invertebrates?

There are five lines of reasoning support it:

1. Haemophilus influenza, a flu-causing bacterium, which has no de novo pathway and cannot utilize Na or Nam, is strictly dependent on NR, NMN, or NAD+ for growth in the host bloodstream.

2. Milk is a source of NR.

3.NR protects murine DRG neurons in an ex vivo axonopathy assay via transcriptional induction of the nicotinamide riboside kinase (NRK) 2 gene.

4. Exogenously added NR and derivatives increase NAD+ accumulation in a dose-dependent fashion in human cell lines.

5. Candida glabrata, an opportunistic fungus that depends on NAD+ precursor vitamins for growth, utilizes NR during disseminated infection.

Nicotinamide Riboside VS Nicotinamide VS Niacin 

Niacin(or nicotinic acid), is an organic compound and a form of vitamin B3, an essential human nutrient. It has the formula C₆H₅NO₂.

Nicotinamide or called niacinamide is a form of vitamin B3 found in food and used as a dietary supplement and medication. It has the formula C₆H₆N₂O.

Nicotinamide riboside is a pyridine-nucleoside form of vitamin B3 that functions as a precursor to nicotinamide adenine dinucleotide or NAD+. It has the formula C₁₁H₁₅N₂O₅+.

Niacin(nicotinic acid), nicotinamide and Nicotinamide riboside (NR) are all NAD+ precursors, and they can be used by cells to create more NAD.

But NR is more potent than nicotinamide and nicotinic acid at increasing NAD+, also NR does not cause flushing and does not inhibit sirtuins when supplementing with high dosage compared with nicotinamide and nicotinic acid.

Nicotinamide riboside (NR) VS Nicotinamide mononucleotide (NMN)

NMN is same as NR, is a derivative of niacin. And the two materials could use to increase NAD+.

But there are differences.

Nicotinamide Riboside Health Benefits

• Nicotinamide Riboside helps energy generation

In animals, NR supplementation reduced NAD consumption, which improved mitochondrial function, rapidly restored muscle mass, and conserve strength NAD levels and exercise volume in older mice, helping maintain muscle mass and function, supports more energy generation.

• Nicotinamide Riboside improved cognitive function

NR preserves the nerve cells in the brain by activating the SIRT3 and Supplementation stimulates the NAD pathways and helps prevent degeneration in mind.

NR boosted cognitive function and slowed progression of Alzheimer's disease in mice given NR for three months.

• Nicotinamide Riboside prevents hearing loss.

By activating the SIRT3 pathway, a UNC study found it helped protect rodents against noise-induced hearing loss.

• Nicotinamide Riboside Protects the Liver

Taken NR Orally increases NAD in the body, which helps protect the liver. NR stopped fat accumulation, lowered oxidative stress, prevented inflammation, and improved insulin sensitivity in the liver of mice.

Furthermore, NR could extend longevity, Increases metabolism, supports the fight against cancer, reduce diabetic symptoms, increases metabolism, may help with weight loss.

Is Nicotinamide Riboside Safe?

Yes, NR is safe.

NR has three published clinical trials confirming it is safe for human consumption

Careful analyzing and stressed all the preclinical and clinical information available on NR assure it is safe and well-tolerated.

Niagen is safe and GRAS, using scientific procedures, under the Federal Food, Drug, and Cosmetic Act (FFDCA).

Nicotinamide Riboside Human Trials

There are many pre-clinical studies have been conducted testing NR in various model systems.

In 2015, the first human clinical studies completed, and the results demonstrated that NR safely and effectively boosts levels of NAD in healthy human volunteers.

A placebo-controlled clinical trial of nicotinamide riboside in obese men by randomized: safety, insulin-sensitivity, and lipid-mobilizing effects

                                 --Published in The American/Journal of Clinical Nutrition

Results: 12 wk of NR supplementation in doses of 2000 mg/d appears safe, but does not improve insulin sensitivity and whole-body glucose metabolism in obese, insulin-resistant men.

Chronic nicotinamide riboside supplementation is well-tolerated and raises NAD+ in healthy middle-aged and older adults.

Nicotinamide Riboside is Especially and Orally Bioavailable in Mice and Humans

                                                   --Published in Nature Communications

Here we define the time and dose-dependent effects of NR on blood NAD metabolism in humans. The report shows that human blood NAD can rise as much as 2.7-fold with a single oral dose of NR in pilot research of one individual and that oral NR elevates mouse hepatic NAD with apparent and superior pharmacokinetics to those of nicotinic acid and nicotinamide. The further show, single doses of 100, 300 and 1,000 mg of NR produce dose-dependent increases in the blood NAD metabolome at first clinical trial of NR pharmacokinetics in humans. Also inform that nicotinic acid adenine dinucleotide (NAAD), which was not considered to be en route for the changing of NR to NAD, is formed from NR and discover that the rise in NAAD is a very sensitive biomarker of effective NAD repletion.

Open-Label, non-randomized research of the pharmacokinetics of the nutritional supplement nicotinamide riboside (NR) and its have effects  on blood NAD+ levels in healthy volunteers

 -Published in PLoS One

This study provides measurable evidence that when we age, and our bodies produce a lot of extra PARP due to accumulated oxidative damage to our DNA, this may result in reduced levels of NAD in our tissues. These lower NAD levels may play a significant role in the aging process by limiting energy production, DNA repair and other vital communications between cells.

Repeat dose NRPT (nicotinamide riboside and pterostilbene) enhances NAD+ levels in humans safely and sustainably: a randomized, double-blind, placebo-controlled study

--Published in NPJ Aging Mechanisms of Disease

Here, we show this first-in-humans clinical trial designed to assess the safety and efficacy of a repeat dose of NRPT. NRPT evaluated in a randomized, double-blind, and placebo-controlled study in a population of 120 healthy adults ages at 60 ~80 years old. The study composed of three treatment arms: placebo, the recommended dose of NRPT (NRPT 1X), and the double dose of NRPT (NRPT 2X). It shows that a repeat dose of NRPT is a safe and effective way to increase NAD+ levels sustainably.

Nicotinamide Riboside optimal dosage

Getting the NR dosage correct can help avoid nicotinamide riboside side effects as well. Most of the researches are in the thousands of milligrams per kilogram of body weight, but the suggested NR supplement dose is 1-200 mg per day.

There are many anecdotal reports of doses up to 600 mg per day, which can increase mental energy and focus, but these do not recommend for first-time users. NIAGEN® has a successful New Dietary Ingredient Notification with FDA (NDIN 882) for daily recommended intake of not more than 180 mg/day.

Nicotinamide Riboside side effects

There are few nicotinamide riboside side effects. A compound is a natural form of vitamin B3 suggesting it's generally safe.

Most users will not have nicotinamide riboside side effects unless physically active. Even then, the loss of physical performance was based on theoretical animal models while there is no human evidence.
