9 Best Nicotinamide Riboside Supplements Backed By Science (2021 Review & Comparison)

Looking for a fountain of youth?

Anti-aging and longevity researcher David Sinclair brought nicotinamide adenine dinucleotide (NAD) into the limelight. Here’s what you might not know though: scientists discovered NAD in the early 20th century. Why is it making a comeback?

It’s the energetic currency keeping your body functioning at its peak. NAD deficiency dramatically speeds up how fast you age age.

Nicotinamide Riboside (NR) is one of the most popular biohacks because it directly quenches low NAD levels.

Fix that deficiency, and maintain youthfulness longer.

Today’s post will give you essential background on choosing the best Nicotinamide Riboside products on the market, and the essential background on why these products stand out.

For quick reference…

The Best Nicotinamide Riboside Supplements of 2021

Best Overall NR: Tru Niagen
Best All-in-One NR Formula: Life Extension NAD+ Cell Regenerator with Resveratrol
Best NR Powder: Botany Biosciences Nicotinamide Riboside Chloride
Best Quality NR: Thorne Research ResveraCel Nicotinamide Riboside
Best Budget NR: Ultra Health Nicotinamide Riboside (use coupon URBAN)

On to the background and then product comparison.

What is NAD+ and How Does NR Help?

Nicotinamide riboside is a form of vitamin B3 (also called niacin or nicotinic acid). Unlike the other forms, reearch shows that NR increases levels of NAD+, a key central metabolism regulator. Core functions of NAD include:

  • Converting food to energy
  • Repairing DNA
  • Creating androgen hormones
  • Building muscles
  • Recovery
  • Activating a group of seven essential longevity proteins called sirtuins

Over 500 different enzymes rely on NAD. Without it, you’d die in 30-seconds.

You’ll live with suboptimal NAD levels. But you’ll age faster and have difficultly performing at your peak.

Supplementing with nicotinamide riboside is an insurance policy against low cellular energy.

Benefits of Nicotinamide Riboside Supplementation

NR’s works primarily to increase the energy available to the body’s many organs and cellular processes. It slows down the aging of tissues throughout the body that become susceptible to degenerative disease

Using NR as a longevity compound is new and we need more studies to fully elucidate uses and effects. Much of the current understanding is based on animal models.

Powerful Nicotinamide Riboside benefits include:

  1. Improved muscle function
  2. Cellular energy generation
  3. Overcoming jet lag
  4. Boosts physical and mental energy
  5. Repairing DNA faster
  6. Restores exercise capacity
  7. Fighting diseases of the brain and body (like Alzheimer’s)
  8. Protecting the brain, liver, and mitochondria
  9. Reducing blood pressure
  10. Decreasing symptoms of diabetes
  11. Helping prevent hearing loss
  12. Increasing metabolism
  13. Enhances blood sugar control
  14. Improving weight loss
  15. Mitigating damage from oxidative stress
  16. Regulating your sleep/wake cycle, (known as the circadian rhythm)
  17. Extending lifespan

The research suggests that taking Nicotinamide Riboside to optimize NAD will restore systems affected by a cellular energy deficit. I always recommend boosting NAD levels naturally and with the precursors first.

Natural Ways to Boost NAD

You can increase your levels two primary ways:

  1. Adding boosting supplements
  2. Making your body more efficient with the current process (salvage pathway)

You’ll get better, longer-lasting results from the latter.

Natural ways to boost your NAD levels without NR or NMN include:

  • Raw honey
  • Fermented foods
  • Sauna sessions
  • Pau D’ Arco tea
  • Fasting

Certain foods contain trace amounts of nicotinamide riboside:

Before you run to the grocery store and stock up: you won’t be able to chug enough milk to get appreciable amounts of NR.

I wrote a mega-guide to naturally boosting your NAD here.

Once you’ve optimized the salvage pathway and are looking for more, these are the best products.

The Problem With Most NR

Heavy metals, impurities, and other banned ingredients regularly contaminate supplements. Third-party reports across brands and ingredients have found outright fraud: some products contain absolutely zero of the stated ingredient but rather another unrelated compound instead.

Since it’s new to supplement manufacturers and commercial sources have only began appearing in the last two years. Suppliers cannot match the demand spike. The market and online stores have become littered with fake (and expensive) NAD boosters.

The brands I trust most have either been directly used in clinical studies, or undergo strict third-party testing. Below is a list of some popular nicotinamide riboside products.

Best Overall NR: Tru Niagen Nicotinamide Riboside

LiftMode is a company popular amongst nootropics and smart drug connoisseurs. They offered NR powders ranging in size from a one gram tub all the way up to ten grams. Their Nicotinamide Ribosides are on the more expensive side. Occasionally I get an email about sales. I’d suggest waiting for one of these blowout sales to purchase.

UPDATE: LiftMode has stopped carrying NR in favor of the related NAD Booster, NMN.

Frequently Asked Questions

Each of the above products should boost your NAD levels. But here is some additional information to help you make the best informed choice for your specific situation.

NR vs MNM: which is superior?

Nicotinamide mononucleotide and nicotinamide riboside are both NAD+ precursors. NMN is more stable than NR and this stability confers additional health benefits. However, in order to use it, first your body must convert NMN into nicotinamide riboside. Some of the NMN is wasted in the process. There’s less evidence behind NMN, and NR has been proven to extend lifespan in mice. Making NR the science-backed best NAD precursor.

Is NR Safe?

Nicotinamide riboside a naturally occurring form of vitamin B3 and thus has been Generally Recognized as Safe (GRAS) by the FDA. Although some users report minor side effects from extremely high doses, there have not been any cases of overdose. Always consult with your doctor before starting new supplements.

What is the best NR dosage?

Research suggests that the ideal dose for nicotinamide riboside is anywhere between 100 to 2000mg per day. Although minimal, side effects do increase with higher doses. The more NR, the greater NAD+ levels. For longevity, 300mg is sufficient. A larger dose of around 1000mg is more effective for increasing energy.

What are the side effects of NR?

Current nicotinamide riboside research has discovered zero side effects in humans. However, some users report trouble sleeping because of the increased energy. A study done in mice found worsened physical performance by 35 percent. These findings have not been replicated in humans, but athletes should be cautious of taking NR.

Should You Supplement Nicotinamide Riboside?

Nicotinamide riboside is one of the best and most effective NAD boosters available.
