Because our cells’ energy production slows down as we get older, our bodies become less efficient. We start putting on excess weight, feeling more fatigued, and having more difficulty fighting off diseases commonly associated with aging.

Scientists are looking into dietary supplements as a potential method of boosting energy and supporting healthy aging. One of the most promising of these is NMN (nicotinamide mononucleotide supplements).

But where can you buy NMN online? Which form of NMN supplementation should you buy? And can it be combined with other anti-aging supplements? Keep reading our guide to help you narrow down your choices and help you decide which online NMN supplement is best!

What Are NMN Supplements?

An NMN supplement is a dietary supplement made with nicotinamide mononucleotide (NMN). NMN is a naturally occurring molecule derived from vitamin B3 (a.k.a. niacin), and it’s a direct precursor of nicotinamide adenine dinucleotide (NAD).

NAD plays a crucial role in our body’s cellular health, as it regulates processes like energy production, nutrient delivery, and cell repair. NMN transforms into the NAD precursor nicotinamide riboside (NR) to enter cells and boost NAD production.

However, as we age, our NAD levels drop and we become at risk of developing age-related conditions like cardiac disease, poor eyesight, and reduced fertility.

The Benefits Of NMN

Taking a regular NMN dose can increase your body’s NAD levels and help slow the aging process. Here are some of the ways that taking NMN capsules can benefit your health.

NMN heart benefitsBetter Cardiac Health

As people age, they become more prone to developing cardiac problems. This is because our blood vessels stiffen or start building up plaque, restricting blood flow and reducing our cardiovascular system’s efficiency at distributing oxygen and other nutrients.

Taking an NMN dose can increase your NAD levels, which reduces cell death and oxidative stress. These benefits can improve your stamina and lower your risk of developing heart disease.

Increased Insulin Sensitivity

Insulin sensitivity refers to how responsive your body is to insulin. When your insulin sensitivity is too low, this causes insulin resistance, which leads to excess weight gain and metabolic disorders.

NMN supplements can improve your insulin sensitivity, lowering your blood sugar levels and reducing your risk of developing type 2 diabetes and obesity.

Improved Brain Function

NMN (nicotinamide mononucleotide) can cross the blood-brain barrier and increase NAD levels, stimulating neural cell repair. As a result, people may feel more focused and alert.

The Risks Of NMN

NMN supplements are safe to take and pose few to no side effects. Human trials have shown no serious changes to factors such as blood pressure and body temperature. However, if you exceed the maximum recommended NMN dose of 1,200 mg/day, you may experience the following:

  • Dizziness
  • Headaches
  • Diarrhea
  • Stomach discomfort

These effects can be avoided by starting with the minimum recommended NMN dose for your weight and age, then increasing it slowly. Discontinue the use of your NMN supplement if you experience any adverse effects.

Different Types Of NMN Supplementation

While browsing online stores for NMN supplements, you may have noticed that NMN comes in different forms. Each one has different release mechanisms and may be more suitable for your needs and preferences. Here’s a quick breakdown of each so you can choose the best NMN supplements for you.


A liquid liposomal form of NMN offers one of the fastest methods of absorption and conversion into NAD. However, this form of NMN is the least shelf-stable and needs to be constantly refrigerated to preserve its ingredients.

Sublingual Tablets

NMN sublingual tablets offer quick, enhanced absorption, making them a popular form for those who have trouble swallowing capsules. These NMN tablets offer more accurate doses than an NMN powder and swiftly boost NAD levels.

NMN Sublingual Powder

A sublingual NMN powder form is easy to dissolve under your tongue and take quickly. Alternatively, you can mix NMN powder into a drink and sip it over a short period as part of your daily routine.

Note that it can be difficult to measure out an exact NMN dose in powder form, so use a milligram measuring scale to ensure you’re taking the correct amount of nicotinamide mononucleotide.

NMN Capsules

NMN capsules offer a delayed-release, precise NMN dosage in a familiar supplement form. These typically break down in the small intestine instead of the stomach to reduce gastric irritation. While some NMN capsules can be dissolved in water, note that this liquid form needs to be consumed immediately or refrigerated to maintain product stability.

Traditional Tablets

Tablets offer a slower-release mechanism, maintaining a steady concentration of nicotinamide mononucleotide (NMN) in your bloodstream. This keeps NAD levels elevated for longer.

However, this slower, reduced absorption means tablets also typically have higher doses of NMN to be effective. This method of supplementation is recommended for those who are wary of experiencing side effects from absorbing high doses quickly.


Lozenges are taken sublingually and allow quick absorption of nicotinamide mononucleotide through the bloodstream. By avoiding digestion in your gastrointestinal tract, you can reduce stomach irritation. This is especially helpful to those with sensitive digestive systems or who need to take supplements on an empty stomach.

Buy The Highest Quality NMN Online From Trustworthy Sources

There are many different NMN supplements available online, but not all of them will be as effective at encouraging good health. Some won’t have enough pure NMN to help with DNA repair or boost energy; others will make broad claims but have no research to back their alleged anti-aging benefits.

Here are some useful tips to help you buy high-quality NMN from trustworthy companies online. Keep these in mind to avoid being ripped off by cost-cutting manufacturers!

Read Customer Reviews

Customer testimonials can give you a lot of valuable insights into an NMN product and its manufacturer. They can tell you if an NMN supplement works, what its benefits and side effects were, and how the company may have dealt with any consumer issues.

Check If The NMN Product Is Third-Party Tested

Many NMN dietary supplements aren’t FDA-regulated and haven’t undergone quality testing, despite their sweeping claims. If it’s too good to be true, it probably is. This is why it’s important to research the product and how rigorously it’s been tested.

The best anti-aging NMN supplements are tested by independent labs to verify ingredients and quality. These independent tests also establish claims about benefits and efficacy. Be wary of manufacturers that claim to be third-party tested but don’t publicly post the results.

Look For A Money-Back Guarantee

There’s always some apprehension if you’re trying out a dietary supplement for the first time. Fortunately, a money-back guarantee can ease some of your woes. If you try a nicotinamide mononucleotide supplement but find that it isn’t working for you, a money-back guarantee entitles you to a refund.

All you have to do is ship back the remaining amount of your NMN product back within a certain period of time. After that, the manufacturer will refund you. Most reputable manufacturers will have this policy to ensure customer satisfaction.

Review Shipping And Payment Policies

If you’re buying your NMN/NAD boosters from an online store, it’s important to find out how much your shipping will cost and how long it will take for your products to arrive. Some stores offer same-day shipping or two-day shipping. Others will ship your order for free if it reaches a certain value.

Don’t forget to check which online payment methods are available for your nicotinamide mononucleotide supplements. Other online stores offer payment in installments, while others will give discounts or cash-back rewards if you pay through specific portals.

Compare Product Ingredient Lists

Some NMN supplements seem to have a great price for the quantity until you start looking at the ingredient list. Be wary of any listed fillers and additives, as well as any ingredients you may be allergic to. Some companies may process their dietary supplement in facilities that handle allergens like dairy or tree nuts, so keep an eye out for this warning on the ingredient label.

Note that many big and small businesses alike add other ingredients to help with your body’s absorption or boost each NMN dose, such as mannitol or vegetarian cellulose. Most NMN supplement brands also indicate if they’re vegan-friendly, soy-free, or gluten-free.

Assess Product Prices

When buying other supplements, it’s important to remember that you get what you pay for. While an NMN product doesn’t have to be outrageously expensive to be effective, be wary if the product is too cheap. A cut-rate NMN supplement may contain too low an NMN dose to have anti-aging benefits.

The best-value NMN supplements will cost roughly $70 per bottle. If a product is priced lower than that, evaluate its manufacturing process and efficacy claims carefully.

Check The Manufacturer’s Website

Viewing product detail pages can have a wealth of information about a company’s business practices and the amount of research done to ensure efficacy. Companies should have the following information on their sites:

  • Ingredient lists
  • Dosage
  • Suggested storage methods
  • Warnings about any side effects
  • Instructions for taking your NMN dose

The best sites will have FAQ sections that will address your basic questions, or live chat agents to handle your requests ASAP. However, it shouldn’t take too long for you to browse for relevant, accurate information on the site on your own.

Forest Leaf’s vegetarian capsules are free of common allergens, so they’re a popular choice for those who want to get more energy from NMN without triggering allergies. However, 250 mg is a low dose for an anti-aging NMN supplement, so you’ll need to take more capsules per dose and it won’t be absorbed as quickly.

Note that while Forest Leaf posts its third-party test results, these tests only measure the relative absorption rates of their NMN dosage – not product purity.

Natural Stacks NMN Capsules

Supplement form: Capsules


  • 250 mg of NMN per capsule
  • 150 mg of Vitamin B3 per capsule
  • 250 mg of Trimethylglycine per capsule

Each bottle of Natural Stacks has 60 capsules, with one pill containing 250 mg of NMN and other ingredients to boost NAD levels. One major advantage that Natural Stacks has over other brands is its transparency about third-party testing. You can easily read current reports about its ingredient suppliers and test results.

Quicksilver NAD+ Gold Liposomal NMN

Supplement form: Liquid


  • 50 mg of NMN per 1 ml dose
  • 50 mg of Trimethylglycine (as betaine) per 1 ml dose
  • Gluten-free, non-GMO
  • Allergen-free

Quicksilver NAD+ Gold delivers gluten-free liposomal NMN in a liquid form, which allows faster NMN absorption into the bloodstream than vegetarian capsules or NMN pills. The company, Quicksilver Scientific, claims to test all its products for heavy metals, ingredient identity, and pesticide residue.

Note that this supplement is temperature-sensitive and needs to be refrigerated upon receipt.

The Bottom Line

Taking NMN can boost your NAD levels and help fight the effects of age-related decline, like lower stamina, excess weight gain, and brain fog. However, with the sheer number and different types of anti-aging supplements made with NMN, it can be tricky to choose the best one online.

If you’re looking for a safe, high-purity dietary supplement for NMN online, Pure NMN powder can give you anti-aging benefits.

FAQs About Buying NMN Products Online

How do I store my nicotinamide mononucleotide supplement?

Store nicotinamide mononucleotide products in a cool, dry place like your refrigerator. High temperatures, extreme temperature changes, and humidity can degrade your NMN supplements, making them less effective.

What is the best form of NMN supplement?

The best form of NMN supplement will depend on your lifestyle and preferences. If you want a fast-acting supplement, a liquid or sublingual powder form is best. If you’re concerned about side effects, a slower-release pill form may be better for you.

Are the best NMN supplements expensive?

No, the best NMN supplements aren’t necessarily expensive. On average, you can get a nicotinamide mononucleotide supplement for $70 a bottle, though prices can go up to $100. Be wary of other brands that sell NMN too cheaply, as they may be packed with fillers or dangerous impurities like heavy metals.

Is a nicotinamide mononucleotide supplement better than NR?

Yes, NMN supplements are better than NR supplements. Research suggests that though both substances increase NAD, NMN (nicotinamide mononucleotide) has several advantages over NR as a NAD precursor. These include its ability to increase insulin sensitivity, its greater number of bioavailable delivery methods, and its lower cost.
