10 Best NAD+ Supplements to Buy in 2023

Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. Most cells in your body use NAD as a coenzyme in the production of energy from glucose. NAD exists in two forms: an oxidized form and a reduced form, which are NAD+ and NADH (H for hydrogen).

best nad supplement on the market

Nicotinamide Adenine Dinucleotide Market size is anticipated to exceed USD 1.4 billion by 2030, as per research report announced by Global Market Insights Inc. NAD market size was recorded at over USD 488 million in 2021. Driven by changing lifestyle choices, the industry is expected to grow at around 13% CAGR (compound annual growth rate) from 2022 to 2030.

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.

Recent years have seen a surge of interest in supplements designed to boost levels of nicotinamide adenine dinucleotide (NAD). Research suggests NAD+ can help your body to repair DNA, boost immune systems and slow the aging process, but people also take supplements for short term gains such as increased energy levels. 

When choosing between the various options available, much will depend on your current health condition and what you’re hoping to get from it. To help you out, we’ve had a look at what’s going on the market to offer a varying selection in the hope that one of them will hit the sweet spot for you.

NMN stands for nicotinamide mononucleotide, a molecule naturally occurring in all life forms. NMN is the direct precursor of the essential molecule nicotinamide adenine dinucleotide (NAD+) and is considered a key component to increase NAD+ levels in cells.

What is NAD+ and What is its Function?

Over 500 different enzymes rely on NAD and without it, you'd die in 30-seconds.

Nicotinamide riboside 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

Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. It exists in two forms: an oxidized form and a reduced form, which are NAD+ and NADH (H for hydrogen).

It is central to energy metabolism and maintaining proper cell function. It plays a crucial role for our mitochondria function, which turn food and oxygen into energy for our body to use. NAD+ also supports the function of sirtuins. Sirtuins are proteins that help protect cells from age-related decline, regulate biological pathways and turn certain genes on and off. However, NAD+ levels decline with age which drive the aging process.

If you have suboptimal NAD levels, you’ll age faster and have difficultly performing at your peak.

Most NAD Supplements Are Fake or Dangerous?

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.

Although there are many NAD+ supplement customer reviews on many online sites, we have curated some of the helpful ones below.

1. TRU Niagen NAD+ Booster Supplement

This is one of the most popular supplements on the market. It contains nicotinamide riboside (NR) which is thought to be one of the fastest and most efficient NAD+ precursors available. It comes FDA approved with doses of 300mg of NR and makes all the usual claims associated with NAD+ of promoting cellular repair, accelerating metabolism and cellular energy production in order to improve your overall health and well-being. Taken over a period of time, therefore, it should have a positive impact on your health and may protect you against the onset of long-term disease. What makes it so popular, if online reviews are anything to go by, is that it can have a more immediate effect by boosting your energy levels. 

TRU Niagen NAD+ Supplements come in 3 sizes:

Amazon Best Sellers: #1 in Vitamin B3 (Niacin) Supplements.

- ChromaDex markets TruNiagen, which is based on its branded Niagen ingredient, which is a form of nicotinamide riboside (NR), the form of nicotinamide that actively crosses into the cell to participate in the NAD+ pathway. 
- Reduces the cellular effects of aging by elevating NAD+, a key coenzyme your body uses for healthy cellular metabolism.
- Nicotinamide Riboside for Energy, Metabolism, Vitality, Muscle Health, Healthy Aging, Cellular Repair 
- Unlike NMN, our key ingredient Niagen was successfully notified two times as an NDI (New Dietary Ingredient) and reviewed as GRAS (Generally Recognized As Safe) under the United States notification programs.

Everyday Renewal
Tru Niagen takes repair down to the foundation of our health, your cells. Every day, our cells are exposed to environmental toxins, hazardous compounds, and pathogens. These environmental factors and pathogens attempt to attack our DNA. Tru Niagen helps counteract this damage by activating tiny repair enzymes called sirtuins.

Fight Daily Stressors
Things like poor diet, alcohol consumption, lack of sleep, sun-exposure, and lack of exercise can be taxing on the body. These stressors affect us on the cellular level, putting our cells into overdrive in order to repair the damage. Tru Niagen helps combat these metabolic stressors.

Fitness Support
Tru Niagen helps fuel your workout and helps you recover after. It gives you fuel by supercharging your cells—focusing on continuous energy, not jolts of energy. After your workout is over, Tru Niagen helps you recover from intense exercise by boosting NAD+, a key coenzyme needed for cellular repair.

Lasting Energy
Tru Niagen promotes natural energy production deep in your cells. There are no stimulants like caffeine added. Tru Niagen helps provide every day sustaining energy through your body's natural energy-generating mechanisms.

"While this is not a scientific review I have been taking Niagen in one form or another non stop for several years. I have been gradually increasing my doses with what I can only describe as a profound effect. Without a doubt I feel younger than 46. I also think I look younger than most people my age. I certainly don't feel my age and have a ton of energy every single day. I also try to eat plenty of vegetables with lots of non meat proteins along with limited meat consumption. I am not a health nut but basically try to stay away excess sugars and processed foods whenever I can. I also do a hard bike ride once or twice a week. I think this also helps the entire aging process some." - Amazon

Over 75% of registered ongoing or completed nicotinamide riboside trials use Niagen®. Here are five of their studies, just to name a few.

- 500mg of Vitamin B3 (Niacinamide) Per Capsule
- No "Niacin Flush"
- Non-GMO, Gluten Free, Soy Free, and Made in a GMP Compliant, FDA Registered Facility

Nutricost Niacinamide Review
After a recent news article about this being a favorite supplement in Australia for sun damage protection, I asked my dermatologist about it. She said it might help prevent me getting as many 'barnacles' as she calls them. You know, those nasty, old-age, sun-damage, crunchy brown or white patches all over your body. (I have many). I'm still on my first bottle but after about two weeks the most amazing thing happened. I happened to scratch an area near one of my barnacles and it just flaked off in my hand. Since then, many more have succumbed. Not all; just some. But I'm happy. Even one less of those ugly bumps is an improvement.

Niacinamide Review
Dr. Conlon has concluded, and Dr Mercola thoroughly agree with her, that the best single NAD+ precursor is niacinamide (also known as nicotinamide), not niacin, NR or NMN. It is now beyond obvious to me why no one is promoting niacinamide. This is because it costs less than one cent a day and as a result there is simply no money to be made in promoting it. Ideally you buy niacinamide powder and use 1 to 1/2 of 1/64th of a teaspoon three times a day (25-50 mg). - Mercola.com.

6. Nuchido TIME+ Nicotinamide, EGCG, Vitamin C, Alpha Lipoic Acid, Zinc

At Nuchido Laboratories science is at the core of everything they do. This is why they conducted a clinical trial on their next generation NAD+ boosting supplement, Nuchido TIME+.

In this trial, they measured levels of NAMPT (Nicotinamide PhosphoribosylTransferase). This is the key enzyme which powers NAD+ production and recycling (the Salvage Pathway) in youthful cells.

Unfortunately, levels of this enzyme decline as we get older and this is one of the main causes of NAD+ decline.

According to Nuchido, their Nuchido TIME+ is the only product clinically proven to restore NAMPT and fix the root causes of NAD+ decline. Precursor supplements such as NR or NMN fail to fix the Salvage Pathway and therefore, fail to address the root causes of NAD+ decline.

This is why precursor supplements can cause further cellular dysfunction such as methyl donor depletion and inadvertently driving inflammation.

Review - My husband and I are in our 60s and have been taking these capsules for a few weeks. We both started with 2 capsules daily and experienced an increase in energy and in focus. We also both had trouble remaining asleep at night and had strange dreams. We have decreased our consumption of the capsules to one per day and have had a resolution to the sleep problems. We both continue to enjoy an increase in energy and in focus. We have reordered this Thorne product and are very satisfied with the results. It would be best to start with one capsule per day and work up from there until you find your own correct dosage.

Review - This product is probably about as close as you can get to the niagen supplements, like Thorne ResveraCel, without actually containing niagen or using the patented process. Nicotinamide is a form of niacin easily processed by the body. And it contains bonus resveratrol. I've only been taking these two weeks, but I've found these supplements give me some mental boost/clarity and physical energy. My skin seems more elastic. I have less appetite (my usual tendency is to over eat) and sleep better. I've lost a couple of pounds. One side effect I get is upset stomach, but the seller/manufacturer claims this will go away with time. Overall, while these supplements are no "miracle cure," I think they are providing some benefit, and I will continue to take them. I'll reevaluate once I've made it through the first bottle.

TWO MONTH UPDATE: I still feel that I am benefiting from this product. Stomach upset has diminished. I have less joint pain. I have more energy and mental clarity. Better sleep. Skin feels younger. No additional weight loss.

10. Peak Performance NMN + Resveratrol

Buy on Amazon (Not available)

About this item
  • Not all NMN supplements are created equal! Many supplements come with just NMN, which by itself is less effective to produce higher levels of NAD which the body needs to prevent cellular degeneration as we age. Peak Performance combines NMN with Resveratrol. Resveratrol works synergistically with NMN as it acts as an accelerator to produce better results in DNA repair.
  • Anti Aging = NMN + Resveratrol! Our cells use NAD+ to produce energy and to activate proteins that repair damaged DNA. Scientists believe that the decline of NAD+ as we age results in many health-related problems. To sustain healthy levels of NAD+ we can supplement this with its precursor, nicotinamide mononucleotide (NMN) . When combined with Resveratrol this supplement becomes even more powerful. Great for cellular + DNA repair, muscle endurance and strength, vascular health and blood flow.
  • What's in your supplement? - Many supplements on the market use standard formulas that may contain cheap fillers and sometimes questionable ingredients. All of our ingredients are carefully chosen and 3rd party tested for purity.
  • Vegan & Allergy Free - Free Of Soy, Milk, Egg, Shellfish, Corn, Wheat & Peanuts. Contains NO Gluten or Preservatives. Manufactured Under The Highest Quality GMP Regulations and USA Standards.

64% of NMN Supplements Fail Tests

ChromaDex NMN Report (Oct 2021): Supplement manufacturer ChromaDex alleges that testing has revealed that more than half of NMN anti aging supplements being sold on Amazon contained almost none of the bioactive molecule.

ChromaDex markets TruNiagen, which is based on its branded Niagen ingredient, which is a form of nicotinamide riboside (NR), the form of nicotinamide that actively crosses into the cell to participate in the NAD+ pathway. Boosting this pathway, and thus maintaining cellular function at a lively, youthful level, has become a prominent theme in recent anti aging research.

Credit: ChromaDex

* The same distributor (SerumLab S&C International LLC) was listed on the product packaging from 10 of the 22 product brands.

Recently researchers have argued that a transporter exists for NMN too, which is something that ChromaDex disputes. It claims that NMN must first be converted into NR in the blood before it can be used by the cells.

In the several years since the NMN transporter discovery was asserted, the NAD+ anti aging field has become crowded with NMN based supplements all seeking a piece of the pie created by ChromaDex and its competitor and one time customer Elysium. (The two companies have been locked in various patent infringement and breach of contract suits for several years.)

Last fall, ChromaDex obtained 22 samples of NMN products being sold on Amazon. Of these, 14 claimed to contain 500 mg of NMN. A further two products claimed 300 mg on the label; five claimed 250 mg and one product claimed 125 mg.

Only one of the 500 mg products came close to meeting label claim. It had 456 mg of NMN. All of the other 13 products in the 500 mg group either came in at below reporting limit (BRL, defined as less than 1% of the stated amount) or, in the case of 3 products, no NMN was detected at all.

Almost all of the rest of the products performed better, having at least 88% of the label claim. A lone 250 mg product was identified as BRL.

In summary, ChromaDex said that 64% of the products tested contained less than 1% of the stated amount of the active ingredient, which should give consumers pause, the company said.

"While this is a limited snapshot of the vast NMN finished product landscape, it does provide a glimpse into the high variability of product quality that is available... According to this study, the majority of the products one might purchase online contain such a small amount of NMN that there would be no clinical benefits achieved from the dose. Another concern with these adulterated products is that the actual contents are not known and could pose a risk to the user," the company said in a statement.

The key question is what ratio of NAD+ does your body need compared to NADH. While the optimal NAD to NADH ratio remains elusive, research suggests that a generally higher NAD to NADH ratio is favorable. 

When it comes to a plain NAD label, it’s not wrong to be identified as a NAD booster. Generating more NAD+ will naturally generate more NADH. However, the specificity of NAD+ is more indicative of what your cells are truly building when using NAD+ boosting supplements.

How can I increase my NAD+ naturally?

- Exercise
- Reduce sun exposure
- Spend more time in warm places, like hot tubs or saunas
- Consume more food with Vitamin B like avocados, steam fish or milk
- Consume fermented food and drinks which contain NAD+ like sauerkraut and kombucha
- Intermittent fasting : Popular fasting plans often include 16- to 24-hour fasting periods twice a week, followed by healthy meals. This eating pattern triggers body shock, which can boost your natural supply of NAD+.- Ketosis Diets : a low-carb, high-protein, healthy fats food plan.

Do NAD+ Supplements Work?

The answer may not be so simple. NAD+ is a ubiquitous and fundamental molecule, involved in many biological pathways and cellular operations. Its ingestion could lead to a mix of positive and negative outcomes, the balance of which might depend on context. NAD+ precursors, consumed orally, may be taken up by some tissues more than others. And different cell types are known to employ distinct metabolic programs, which could lead to tissue-specific responses to NAD+.

Concerns and Cautions: Be aware that some of these NAD supplements provide amounts of vitamin B-3 above the established daily upper tolerable intake level. There is also a theoretical safety concern that compounds that raise NAD+ levels like, nicotinamide riboside, as well as NAD, NADH, and possibly NMN, may promote the growth of existing cancers.
