Looking for your fountain of youth?
Anti-aging and longevity celebrity Dr. 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.
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 the best Nicotinamide Riboside products on the market, and what makes each of these products stand out.
For quick reference…
The Best Nicotinamide Riboside Supplements of 2025
Best Overall NR: Ultra Health 300C Bulk
Strongest NR: Ultra Health Liposomal Nicotinamide Riboside
Most Recommended NR: Tru Niagen
Best All-in-One Formula: ProHealth Nicotinamide Riboside Pro Complete
Highest Quality NR: Thorne Research ResveraCel Nicotinamide Riboside
On to the background and then product comparison.
What is Nicotinamide Riboside?
Nicotinamide riboside (NR) is a form of vitamin B3 (also called niacin or nicotinic acid). Unlike the other forms, research 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
You’ll live with suboptimal NAD levels. But you’ll age faster and have difficulty performing at your peak.
Supplementing with nicotinamide riboside is an insurance policy against low cellular energy.
Benefits of Nicotinamide Riboside Supplementation
NR 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 most 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:
- Improved muscle function
- Cellular energy generation
- Overcoming jet lag
- Boosts physical and mental energy
- Repairing DNA faster
- Restores exercise capacity
- Fighting diseases of the brain and body (like Alzheimer’s)
- Protecting the brain, liver, and mitochondria
- Reducing blood pressure
- Decreasing symptoms of diabetes
- Helping prevent hearing loss
- Increasing metabolism
- Enhances blood sugar control
- Improving weight loss
- Mitigating damage from oxidative stress
- Regulating your sleep/wake cycle, (known as the circadian rhythm)
- Extending lifespan
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 via two primary strategies:
- Adding boosting supplements
- 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.
Most NR Supplements Are Fake or Dangerous?
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, supplement manufacturers and commercial sources have only begun appearing in the last few years. Suppliers cannot match the demand spike. The market and online stores have become littered with fake (and expensive) NAD boosters.
The Top NR Products Currently Available
The brands I trust most have either been directly used in clinical studies, or undergone strict third-party testing. Below is a list of some popular nicotinamide riboside products.
Best Overall: Ultra Health NR 300C (Bulk)
Overview
NR Dose: 300mg RiboGEN NR
Contents: 300 capsules
Serving Size: 1 capsule
Specialty: Best value & very pure
Quality: No excipients or additives
Rating: 4.8
Each capsule contains the samepatented RiboGENTM as inside their best-selling product. Ribogen is the strongest NR on the market. If you can get over the sticker shock, the 30C line of Ultra Health NR comes out to under $0.90 per serving. A price that’s usually only available to vitamin shops, doctors, and clinics.
As with all their products, 30C is pure pharmaceutical-grade nicotinamide riboside, with zero excipients or additives. Recently, they upgraded this line to use a lipid polymer (enteric) coating. This helps it remain intact through abrasive stomach acid. Resulting in better absorption in the small intestine, and outstanding bioavailability. Since this line is intended for resale by medical professionals, it comes in a sealed mylar pouch.
With Ultra Health 300C, you get the same quality NR used in medical research and clinical studies, but at the lowest price per dose.

NR Questions & Answers
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. There’s less evidence behind NMN, and NR has been proven to extend lifespan in mice.
Is NR Safe?
Nicotinamide riboside is 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.
The Best Nicotinamide Riboside Supplements on Earth: Final Verdict
Nicotinamide riboside is one of the best and most effective NAD boosters available (though longevity scientists like David Sinclair prefer NMN supplements).
Anti-aging biohackers have reported reversing their “biological age” and dramatic energy improvements from this new supplement.

Depending on your genes and lifestyle (see my review of SelfDecode, the top DNA analytics software to easily understand your genes), you may benefit tremendously from taking either NR or NMN. SelfDecode will tell you if supplementation is a waste of money or crucial.

Beware of the many fake and adulterated products that have flooded the NAD supplement market.
Using a contaminated product will do more harm than good. Choose one of the products above to slow aging, increase your energy, and feel your best.

Please add #18 to this article: nicotinamide riboside causes breast and brain cancer
Hi Kane,
I believe you are referring to this study which shows a correlation between the metastases of certain cancers and nicotinamide riboside supplementation. While I agree that it’s an important observation, I couldn’t find anything in this study that shows NR causes cancer. Any more than anabolic (and vital) factors like essential amino acids, mTOR activators, or even other NAD+ precursors. I have a feeling that if they replicated this study for anything that dramatically increases NAD+, molecule or lifestyle habits, they will find something similar.
It’s quite possible that I am missing something or perhaps you were referring to another study?
