Yes, you can buy NAD+ injections online, but the process looks different from adding a supplement to your cart. Injectable NAD+ therapy requires a licensed provider, a prescription, and a compounding pharmacy.
This article breaks down exactly how to get NAD+ safely, what to expect, and whether you're actually a good candidate for treatment.
What Is NAD+ and Why Does It Decline?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell in your body. It's involved in energy metabolism, DNA repair, and the activation of proteins called sirtuins -- which play a central role in how cells respond to stress, aging, and inflammation.
The problem: your levels don't stay constant. Your NAD+ levels at 50 are not your NAD+ levels at 25. Research measuring human tissue confirms what most people feel before they can name it -- a steady, significant decline that tracks directly with age. That decline is associated with reduced mitochondrial efficiency, slower cellular repair, and the kind of fatigue that doesn't resolve with more sleep.
If you've been doing everything right -- sleeping enough, exercising, managing stress -- and still feel like you're running on half a tank, declining NAD+ is one mechanism worth understanding.

Injectable NAD+ vs. Oral Supplements: What's the Actual Difference?
This is the question most people skip, and it's the most important one to answer before you spend a dollar on either.
Oral NAD+ precursors--like NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) are converted to NAD+ through a multi-step metabolic process. They may work, and the research supporting them is real. But there are two absorption problems that compound with age.
- The first is first-pass metabolism: your gut and liver process a meaningful portion of the dose before it reaches systemic circulation.
- The second is more specific to aging: NAMPT, the enzyme that drives NAD+ biosynthesis from these precursors, declines in activity as you get older.
So the oral route becomes less efficient at exactly the moment your baseline NAD+ is already falling. Injectable therapy sidesteps both issues.
Injectable NAD+ delivers the coenzyme more directly into your bloodstream or tissue, which changes the absorption profile. That doesn't mean injections are automatically better for every person–it means they're a different tool, with a different use case.
Is It Legal and Safe to Buy NAD+ Injections Online?
Yes, with the right provider. However, injectable NAD+ does require a prescription in the US. That means the only legal route to purchasing NAD+ injections online is through a telehealth platform that connects you with a licensed provider who can evaluate your case and issue a prescription.
What that process looks like at a legitimate telehealth company: you complete an online medical intake form, a licensed clinician reviews your medical history, and if appropriate, your prescription is sent to a licensed compounding pharmacy. The medication is then shipped to your door. At Strut Health we do just that and we offer follow up care to make sure everything is going well and adjust dosing accordingly.
The red flags to avoid: any site selling injectable NAD+ without requiring medical intake, without provider sign-off, platforms operating outside the US without clear regulatory oversight, or anything marketed as 'no prescription needed.' Injectable medications require prescriptions for a reason, dosing, contraindications, and quality control all matter.

What Does NAD+ Therapy Actually Do?
Your cells can't make energy without it. Every time your body converts food into usable fuel, NAD+ is involved in the process. It's what allows your mitochondria to produce ATP, the energy molecule your body actually runs on. When NAD+ drops, energy production gets compromised at the source.
And as we age (and NAD dips), it’s the mechanism behind the fatigue and mental fog that tend to creep in and don't resolve no matter how well you sleep.
NAD+ also activates a family of enzymes called sirtuins, which manage DNA repair, stress responses, and inflammation. Sirtuins have been studied extensively for their role in longevity, activating them has been shown to extend lifespan in mammals. But they can't do their job without adequate NAD+. When your levels fall, sirtuin activity falls with it, even if the enzymes themselves are still there.
Think of NAD+ as a real-time signal your cells use to gauge their own health. When levels are sufficient, your cells prioritize repair and performance. When they're not, your cells shift into a kind of conservation mode -- and you feel it.

What to Expect When You Start NAD+ Injections
The experience varies by person, but here's a realistic picture.
Most protocols involve subcutaneous injections, so the injection is just right under the skin, not into a vein or muscle. Depending on your provider's recommendation and your goals, frequency can range from daily to a few times per week. Strut's compounding pharmacy formulations are designed for at-home self-administration, and your provider will walk you through technique.
Timeline-wise: don't expect overnight results. Some people report noticing improved energy and mental clarity within the first two to three weeks. Others need a longer consistent run before seeing meaningful changes. NAD+ isn't a stimulant, it's working at a cellular level, which means the effects build rather than spike and fall.
Side effects are generally mild when the therapy is dosed and administered correctly: possible injection site discomfort, flushing, or nausea at higher doses. These typically resolve quickly. If you have a history of conditions affecting energy metabolism, kidney function, or are pregnant, your provider will need to factor that into the evaluation.
What the process looks like at Strut Health:
1. Complete your online intake form (10 minutes)
2. Licensed provider reviews your history and goals
3. If appropriate, prescription sent to a compounding pharmacy
4. Medication shipped directly to your door
5. Ongoing provider access for any questions
Who Is a Good Candidate for NAD+ Therapy?
NAD+ injections aren't a universal prescription. Here are the situations where the therapy tends to make the most clinical sense:
- Persistent fatigue that doesn't improve with sleep, nutrition, or exercise adjustments
- Cognitive sluggishness or difficulty with focus and mental clarity
- Adults over 40 experiencing the metabolic and energy shifts associated with age-related NAD+ decline
- People recovering from significant physical stress
- Those looking to support long-term cellular health alongside other wellness interventions
A few groups who should discuss carefully with their provider before starting: people with active kidney disease, those taking medications that interact with NAD+ metabolism, and anyone who is pregnant or breastfeeding. Your Strut provider will flag anything relevant during your intake review.
Frequently Asked Questions
What is the best way to get NAD+ therapy online?
The most practical and medically sound way to access NAD+ therapy is through a licensed telehealth provider. This ensures you're getting a properly dosed prescription from a quality-controlled compounding pharmacy, with a clinician evaluating whether the therapy is appropriate for your specific situation. OTC oral supplements are an option for some people, but injectable therapy requires provider oversight.
