Best NMN Supplements Comparison Table

Best NMN Supplement Overall: Omre NMN + Resveratrol

Our Thoughts on Omre NMN + Resveratrol

Omre NMN + Resveratrol is our pick for the best NMN supplement overall because it includes a clinically backed dose of 500 milligrams of ultra-pure NMN and 500 milligrams of micronized trans-resveratrol, paired with BioPerine®, which may help with absorption. 

The resveratrol in this formula is beneficial because it amplifies the benefits of NMN through complementary cellular pathways. We also like Omre’s commitment to third-party testing (COAs are available on the product page) and GMP-certified production, ensuring ingredient purity and safety.

Pete tested this NMN supplement, rating it a 5 out of 5 for his first impression. The supplement comes in a “small, black plastic container with a screw top lid that opens and closes easily,” he said. “The label looks sophisticated, and the company logo is written in gold lettering.” Our team loved the clean, aesthetic look.

He found the instructions to be clear and easily understood, rating them a 5 out of 5. “It says to take two capsules daily in the morning with food, or as recommended by your healthcare professional,” Pete noted. We liked the serving size with this product, making it more convenient for folks who may be taking other supplements. 

Pete rated swallowability of this supplement as a 3 out of 5. He described the pills as “average size clear capsules with an off-white powder inside. The capsules are about one inch in length and one centimeter in diameter.”

Best NMN + Resveratrol Supplement: Wonderfeel Youngr NMN

Our Thoughts on Wonderfeel Youngr NMN

Wonderfeel Youngr NMN earned our pick for the best NMN + resveratrol supplement because of its science-backed formula that goes beyond basic NAD+ activation. Developed by a Harvard-trained medical expert, it includes NMN, resveratrol, and antioxidants. When paired, NMN and resveratrol have been studied and found to work together to help support healthy aging and improved energy.

This formula combines 20 micrograms of vitamin D (100% of your daily recommended value) with 900 milligrams of NMN and 100 milligrams of trans-resveratrol. Most human study data does start on a lower dose of 100 to 200 milligrams of NMN, slowly working up to 500 milligrams, according to Jillian Robillard, MS, RD, LDN. So, you may want to start with a lower dose than Wonderfeel’s serving size. Unique to Wonderfeel, this product also includes 50 milligrams of olive extract, which may offer some anti-inflammatory properties. 

Pete tested this NMN supplement, rating it a 5 out of 5 for his first impression. “The container for this supplement is interesting, it looks like a pill and has an easy-to-open screw top lid. The label is blue with both white and yellow labeling, and it’s easy to read,” he said. He thinks the container size should be pretty travel friendly. 

Our tester found the instructions straightforward and easy to understand and follow, rating them a 5 out of 5.  “Take two capsules in the morning with or without food,” he noted. “They’re average size white capsules, about one inch in length and one centimeter in diameter,” Pete said, rating the swallowability a 3 out of 5.

Pete didn’t experience any negative side effects from Wonderfeel Youngr NMN. “The full capsule serving size contains nearly 1,000 milligrams of NMN,” he said. “Most studies on humans are using dosages between 250 and 500 milligrams per day, so this is above that. That said, dosages up to 1,200 milligrams per day have been studied with no serious adverse effects reported.”

However, there isn’t much long-term research with high doses of NMN, according to Jillian. So, for the sake of safety, we recommend starting at a lower serving or taking the product for a shorter period of time to assess your body’s tolerance and response.

Best Budget NMN Supplement: Nutricost NMN

Our Thoughts on Nutricost NMN

Nutricost NMN is our pick for the best budget NMN supplement due to its simple, single ingredient and price per serving of $1.13. It’s a budget-friendly way to purchase and start a NMN routine. This product offers a straightforward formula, packing 500 milligrams of NMN per serving. 

Pete tested this NMN supplement, giving it a 5 out of 5 rating for his first impression. “The capsules come in a small, white plastic container with a screw top lid. It’s small enough to be travel-friendly,” he said.

He rated the instructions and ease of following them as a 5 out of 5. The directions say, “As a dietary supplement, take two capsules daily with eight to twelve ounces of water or as directed by your healthcare professional,” Pete noted.

Our tester rated swallowability and taste both as 3 out of 5. He observed that the capsules are of roughly average size, about 1 inch in length and 1 centimeter in diameter. Each pill is a clear capsule with a tan powder inside. Pete felt the pills have a “slightly bitter taste.” 

He thinks the dose is plenty, as 500 milligrams of NMN is the amount that’s commonly used in most human studies. “Efficacy in humans is still being studied, and it seems to be well tolerated by most people,” Pete said. However, this product isn’t ideal for folks who want resveratrol included. In that case, we recommend Wonderfeel Youngr NMN.

Best Natural NMN Supplement: GenuinePurity Liposomal NMN

Our Thoughts on GenuinePurity Liposomal NMN

GenuinePurity Liposomal NMN is our pick for the best natural NMN supplement because the brand uses all-natural ingredients, combined with a patented liposomal delivery system that improves NMN bioavailability. This helps ensure that each dose survives the digestive process and reaches cells where it supports NAD+ production for energy, repair, and healthy aging. Each batch is third-party tested in cGMP and FDA-registered US facilities, with certificates of analysis provided to verify its filler-free, non-GMO, and allergen-free formulation.

GenuinePurity’s formula is pretty simple, offering 250 milligrams of NMN per serving. That said, the serving size is only one capsule, so if you want a higher dose of NMN, you can simply take two capsules. 

Pete’s first impression of the product was positive; he rated it a 5 out of 5 in this category. The supplement comes in a “small, white plastic container with a screw top lid. It opens and closes easily, and is small enough to be travel-friendly,” Pete said.

The instructions were easy to read and to follow, so Pete rated them a 5 out of 5. “The suggested use is to take one capsule daily, preferably with meals or as by directed by a healthcare professional,” he said. The pills are “small, clear capsules with an off-white powder inside.”

Pete didn’t have any negative side effects or taste. Unlike other options on this list, though, GenuinePurity’s formula does not offer any added, beneficial ingredients. If you’re wanting a product that offers a few more potential perks, we suggest Omre NMN + Resveratrol.

Best Vegan NMN Supplement: PartiQlar Pure NMN

Our Thoughts on PartiQlar Pure NMN

PartiQlar Pure NMN is our pick for the best vegan NMN supplement because it includes pharmaceutical-grade, plant-based NMN with over 99% purity. Pure NMN is third-party tested for purity and potency, free from fillers, allergens, GMOs, and gluten, and manufactured in FDA-registered, GMP-compliant US facilities to ensure quality. 

PartiQlar offers 500 milligrams of NMN per serving in a vegetable cellulose capsule, which is safe for those following a vegan diet. We also especially love that PartiQlar displays their lab testing data directly on the product page—this is exactly the level of transparency you want with a supplement.

Pete rated this product a 5 out of 5 for first impressions. “It’s a small white plastic container with a screw top lid. The label is a dark gray with white lettering that’s easy to read,” he said.

Our tester rated the instructions and ease of understanding them as a 5 out of 5 as well. Of the supplement, Pete said: “It’s an average sized clear capsule with a white powder inside. The recommended serving size is one capsule per day.” Many NMN supplements on our list require at least two capsules per serving size, so we love that this product supplies a clinical dose in one pill.

Pete didn’t experience any side effects or aftertaste when testing these capsules. He says the 500 milligrams of NMN is a dose that’s been clinically studied and should provide the potential benefits that one would look to an NMN supplement for.

Other NMN Supplements We Tested

We tested many NMN supplements hands-on in our lab. Here are a few that we considered but didn’t make our list of top picks, and why.

• We tried Double Wood Supplements NMNH supplement but left it off our list because it’s slightly different from NMN, and is a reduced form. NMNH hasn’t been studied to the same extent and is less proven to have potential anti-aging benefits.
• We also tried Life Force’s Peak NMN. It didn’t make our list because the serving size is three larger-than-usual capsules, and this is a less appealing daily dose.

What is an NMN Supplement?

An NMN supplement is a dietary supplement that has nicotinamide mononucleotide. It’s a molecule found in all living cells that acts as a direct precursor to NAD+ (nicotinamide adenine dinucleotide), which is an important coenzyme for cellular energy, metabolism, and DNA repair. NMN is naturally present in foods like broccoli and avocados, but only in very small amounts, which is why you might be interested in trying a supplement to boost your NMN intake. As we age, our natural NAD+ levels decline, which can lead to decreased energy and slower metabolism. People take NMN supplements to potentially help promote longevity, improve energy production, and protect their cells from oxidative stress.

How We Tested and Selected the Best NMN Supplements

We tested and evaluated NMN supplements and scored them on a scale of 1-5 for factors such as first impressions, easy-to-follow directions, swallowability, side effects, and value. Our testers evaluate the products based on their own individual experiences and preferences. We then review their testing feedback and data to share our findings and recommendations with you.

Formula

When selecting and testing NMN supplements, we worked with a certified nutrition coach to ensure each formula meets the highest standards for efficacy and safety. The evaluation process focuses on clinically supported dosages that reflect current research, seeking NMN products that deliver the optimal amounts shown in peer-reviewed studies. Ingredient quality and transparency are top priorities, and we favored NMN supplements made in GMP-certified facilities, with third-party testing, and free of unnecessary additives.

Taste and Texture

Flavor is a big part of our testing process. We ask our testers to provide feedback on the taste, aftertaste, and swallowability of the NMN supplements. 

Serving Size

Serving sizes for NMN supplements range from a single capsule to multiple pills. Whenever possible, we chose NMN products that required fewer capsules per serving for added convenience.

Third-Party Testing

We selected NMN supplements that have been verified through third-party testing for safety, purity, and label accuracy. This process also screens for harmful substances like heavy metals and pesticides.

For athletes, third-party testing is crucial to confirm there are no banned substances—products should be sport certified. Since the FDA does not regulate supplements, independent verification is essential for safety, accuracy, and consumer trust.

Value

When considering value, we place a higher value on brands that source their ingredients in America and have certifications, such as Informed Choice.

How to Find the Top NMN Supplements for You

NMN supplement needs vary based on your age, lifestyle, and any specific health goals you may have related to energy or cellular support.

Consider these factors when choosing the most suitable NMN supplement for you.

Your Body’s Needs

NMN supplements can support cellular health and energy production, but they aren’t essential for everyone. Think of them as an optional addition to a balanced lifestyle rather than a must-have supplement.

Formula

Everyone has different dietary needs, so it’s worth checking the ingredient list before purchasing. Some NMN formulas include added vitamins, minerals, or supportive compounds like resveratrol, which might align differently with various diet types or fitness goals. If a supplement includes additional nutrients, compare them with your recommended daily values (RDVs) to avoid excess intake. Choosing a formula that complements your existing nutrition can help you make the most of your NMN supplement.

Cost

NMN supplements are typically taken every day, and can be pricey, so you may want to consider your budget before purchasing. Cleaner formulations, meaning those without artificial sweeteners or additives, may cost more because of their higher quality and ingredient sourcing.

Third-Party Testing

Because the FDA does not regulate supplements, third-party testing provides independent verification of a NMN supplement’s safety, purity, and label accuracy. This process protects against risks like mislabeling, contamination, or banned substances, giving you confidence in the products you choose. Independent testing is crucial for ensuring both product quality and safety.

Benefits of NMN Supplements

Much like a protein powder or creatine supplement, NMN supplements can offer an array of health benefits, potentially helping your longevity and metabolic health.

• Supports healthy aging: NMN supplements can potentially slow age-related decline by increasing NAD+ levels, which assist in DNA repair, cellular metabolism, and energy production. Clinical trials show NMN supplementation may improve muscle strength, insulin sensitivity, and protect cellular integrity, leading to healthier aging and longer lifespan.
• Enhances metabolic and physical function: NMN supplementation has been shown to increase physical performance, energy, and metabolic health through its effect on NAD+ levels. Studies reveal improvements in insulin sensitivity and muscle function, with users reporting increased stamina and healthier metabolism, which may help combat fatigue and support active lifestyles.

How to Take NMN Supplements

NMN supplements are typically taken in the morning, ideally on an empty stomach, to align with your body’s natural NAD+ production cycle and to optimize absorption and daytime energy benefits. Consistent daily use is important to ensure that you get the benefits of the supplement. NMN supplements aren’t a magic pill, unfortunately. While they may help support healthy aging when taken consistently over time, we still recommend prioritizing healthy habits, like a well-rounded diet and regular exercise plan.

What to Avoid in NMN Supplements

There are important factors to avoid when selecting a NMN supplement:

• Avoid impurities and poor manufacturing practices: Choose a NMN supplement that is certified by third-party organizations, such as cGMP-certified. It’s also important to look for the product’s certificate of analysis showing test results on the product page.
• Avoid unnecessary filler ingredients: Some NMN supplements include fillers or preservatives that can cause allergic reactions or digestive discomfort, especially in those sensitive to soy, gluten, or common preservatives. Avoid proprietary blends that do not transparently disclose the NMN content, as these make it harder to track the exact dosage you are getting.

Frequently asked questions

What brand of NMN is best?

Omre NMN + Resveratrol is our pick for the best NMN supplement thanks to its clinically dosed blend of ultra-pure NMN and micronized trans-resveratrol, enhanced with BioPerine® for improved absorption. The inclusion of resveratrol helps support NMN’s benefits by working through complementary cellular pathways, offering enhanced support for energy and longevity. Omre’s strong focus on quality is reflected in its commitment to third-party testing (COAs available directly on their site) and manufacturing in GMP-certified, FDA-registered facilities, ensuring a high standard of purity and safety.

What is the best form of NMN to take?

The clinically dosed amount of 500 milligrams is generally the best form of NMN to take. NMN supplements typically come in capsule form.

Do NMN supplements really work?

NMN supplements have shown promising effects in raising NAD+ levels, supporting cellular energy, and promoting healthy aging in both animal and early human studies, suggesting that they can be effective for some people. Clinical trials in humans indicate NMN may improve metabolic health, insulin sensitivity, and physical performance, but research is ongoing and long-term benefits in large populations are still being studied.
