Buy NAD+: How to Choose the Right Supplement or Injection

What is NAD+? And Why Are People Buying It?

You eat well. You exercise. You even sleep eight hours (sometimes). But something still feels… off. You’re more tired than you used to be, recovery takes longer, and your brain feels a little foggier each year. Scientists suggest that a molecule called NAD+ (nicotinamide adenine dinucleotide) might be part of the puzzle.

NAD+ (nicotinamide adenine dinucleotide) is a molecule found in every cell of your body. It plays a role in energy production, DNA repair, and healthy aging. 

However, NAD+ levels naturally decline as you get older. By mid-age, your body may have significantly less NAD+ than it did in your twenties. 

This is why NAD+ supplements have gained so much attention. Many people are looking for ways to support their cellular health and boost energy. But with so many products on the market, knowing what to buy (and what to avoid) can be confusing and overwhelming at times. So, here’s what you should know.

Types of NAD+ Products You Can Buy Online

NAD+ is available as an oral supplement, an injection, and an IV formulation.

‍

NAD+ Oral Supplements (Capsules, Powders, and Liposomal)

Oral supplements are the most popular and accessible option.

The two most studied NAD+ precursors are NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside). These compounds convert into NAD+ once they’re inside your cells.

NMN sits just one step away from becoming NAD+ in the conversion pathway. However, NR needs to be converted to NMN first. Research shows that 300 mg of NR daily was associated with an increase in blood NAD+ levels after eight weeks. Meanwhile, NMN has been shown to be safe in clinical trials at doses up to 1,200 milligrams per day for several weeks.

NAD+ Injections

NAD+ injections bypass the digestive system, delivering the molecule straight into your bloodstream. 

The trade-off is that injections require a prescription and medical supervision. They also tend to cost more than oral options. For those who want a more targeted approach, injections can be a good option when administered and monitored by a licensed healthcare provider.

‍

NAD+ IV Therapy

IV therapy delivers NAD+ directly into your bloodstream through an intravenous drip. But it does come at a higher price tag. Sessions typically range from $250 to over $1,000 each.

IV therapy is available at specialized clinics, and some providers offer at-home sessions.

‍What to Look for When You Buy NAD+ Online

The NAD+ supplement market is largely unregulated, which means that product quality varies. So, here’s how to protect yourself:

• Check for third-party testing: Look for certifications from programs such as NSF or USP. These organizations verify purity, potency, and safety. This step is really important: according to lab testing by Niagen Bioscience, a leading NR manufacturer, 87% of tested NR supplements didn't match their label —a finding corroborated by industry publication NutraIngredients-USA.
• Read the ingredient label carefully: Avoid products with proprietary blends that hide exact dosages. A quality product will clearly state whether it contains NAD+, NMN, or NR, and the exact amount per serving.
• Buy from verified sellers: Purchasing directly from the manufacturer or an authorized retailer reduces the risk of getting a counterfeit or mislabeled product.
• Watch for red flags: Be skeptical of products that promise to reverse aging or cure diseases. If it sounds too good to be true, it probably is.
• Look for supporting ingredients: Some NAD+ supplements include complementary ingredients. For instance, resveratrol activates sirtuins, which are proteins also involved in metabolism and cellular health. Black pepper extract (piperine) is also a proven bioavailability enhancer for many nutrients, though its effect on NAD+ precursors hasn’t been studied.

Where Can You Buy NAD+ Supplements and Injections?

Oral NAD+ precursors (NMN and NR) are widely available over the counter; you can find them on Amazon, brand websites, health retailers, or supplement shops. No prescription is needed. 

If you go this route, prioritize products with third-party testing and verify NR or NMN content, as independent testing has found that many products on the market don’t match their labels.

NAD+ injections are a different story. Because injectable NAD+ is a compounded medication, you’ll need a prescription from a licensed provider. The most common routes include:

• Telehealth platforms: Eden offers an NAD+ injection program where you complete an online evaluation, get matched with a licensed prescriber, and have your injections shipped directly to your door from a compounding pharmacy. 
• Compounding pharmacies: Eden’s pharmacy network with state-licensed compounding pharmacies prepares NAD+ injections per a licensed provider’s prescription. 
• Longevity and functional medicine clinics: Many integrative health clinics now prescribe NAD+ injections (and IV therapy) as part of broader wellness programs. These tend to cost more but often include lab work, ongoing monitoring, and dosing as determined by your prescriber.

Whichever route you choose, confirm that your provider uses a state-licensed compounding pharmacy, conducts a real medical evaluation before prescribing, and offers ongoing access to a licensed clinician. Avoid any site that sells injectable NAD+ without requiring a prescription.

Final Thoughts

Buying NAD+ online doesn’t have to be complicated, but it does require some homework. Choosing the wrong supplement could mean you’re paying for something that doesn’t deliver or match the label.

When buying NAD supplements, focus on precursors such as NMN or NR, verify third-party testing, and purchase from reputable sources. Start with a lower dose and give it time. 

If you’re unsure about NAD, discuss your options with a licensed healthcare professional; it’s not right for everyone, and a professional can determine what’s best for your specific situation.
