NAD+ Injections: Benefits, Dosing and What to Expect

Last updated November 11, 2026 · Reviewed by the Gala Health team

Why people take NAD+ injections

NAD+ (nicotinamide adenine dinucleotide) sits at the center of how cells make energy. A 2021 review in Nature Reviews Molecular Cell Biology describes it as a coenzyme for the redox reactions of energy metabolism, and as fuel for enzymes involved in DNA repair and stress responses, such as PARPs and sirtuins.

The same review reports that tissue and cellular NAD+ falls gradually with age in several species, including humans, by 10 to 65 percent depending on organ and age. That is the idea behind NAD+ therapy: restore a resource that wanes. Newer human data are more mixed, though. A 2026 study across seven human cohorts found whole-blood NAD+ stable with age. For the full background, read what NAD+ is.

NAD+ injection benefits: what the evidence shows

Here is each benefit people ask about, next to what the published human research supports today:

Benefit people ask about	What human studies show
Higher NAD+ levels	Shown for oral precursors: in a 2026 systematic review, oral NR and NMN consistently raised NAD-related levels in blood or immune cells. For directly infused NAD+, a 2019 pilot found plasma NAD+ did not rise for the first 2 hours of a 6-hour IV infusion, then increased
Energy and fatigue	Not established. The 2026 review found effects on functional outcomes mixed, often null
Metabolism	Mixed. Some small oral precursor trials reported changes in one measure, such as muscle insulin sensitivity with NMN, while others found no difference from placebo
Healthy aging and longevity	Not shown in people. The 2026 review called clinical effectiveness for anti-aging or wellness inconclusive
Results from injected NAD+ itself	No eligible outcome trials of intravenous or intramuscular NAD+ for anti-aging or wellness, per the 2026 review. We found no published outcome trial of subcutaneous NAD+

So what is the real benefit of NAD+ injections? The biochemistry is solid, NAD+ is essential, and raising it is achievable. Whether that turns into a benefit you can feel or measure has not been proven in trials yet. A program worth trusting says so plainly, and so do we. Gala Longevity does not promise a timeline or an outcome.

Before-and-after claims you see online are anecdotes, not trial results. Results for NR and NMN by mouth do not automatically apply to NAD+ given by injection.

NAD+ injection vs IV vs oral

	Subcutaneous injection	IV infusion	Oral NR or NMN
What it is	NAD+ injected just under the skin, at home	NAD+ dripped into a vein over hours, in a clinic	A precursor capsule the body converts into NAD+
Human data	No published outcome trials found	A 2019 pilot in 8 healthy men: 750 mg over 6 hours, no adverse events observed during the infusion; no outcome trials	Many small randomized trials: NAD+ markers rise, outcomes mixed
Time per dose	A few minutes	Hours in a chair	Seconds
Where it fits	Gala's NAD+ format, after provider review	Clinics and IV lounges	Capsules bought without a prescription

The IV pilot is useful for one detail. Plasma NAD+ and its breakdown products did not change for the first 2 hours of infusion, which the authors read as infused NAD+ being rapidly and completely removed from the blood at that rate. In other words, a long drip does not simply top up blood NAD+.

NAD+ injection dosing and how often

There is no FDA-labeled dose for NAD+ injections, because there is no FDA-approved NAD+ injection. No published trial has set a subcutaneous dose or schedule either. That means dose and frequency are a clinical decision, not a number to copy from a forum.

At Gala, a licensed provider reviews your intake asynchronously and confirms the dosing that fits you before anything ships. Your instructions come with your prescription. Your initial visit covers up to a 3-month supply, one month plus two refills, and a short quarterly check-in keeps the next supply coming.

What to expect when you start

Day 1 to 2: a licensed provider reviews your online intake in a roughly 5 to 7 minute async consult, with no video call, and confirms the compound and format that fit your history.
Week 1: your first shipment arrives, with one month on hand and two refills on file.
Months 2 to 3: refills ship automatically as part of your initial supply.
Month 3 and on: a short async questionnaire keeps your provider current so your next supply ships without an office visit.

How you feel varies by person and by goal, and no single timeline can be promised. Injection-site redness or soreness is possible with any subcutaneous medicine. Read NAD+ injection side effects for what is known, and when to call a clinician.

Who should not take NAD+

Gala's intake screens out two groups before a provider reviews your case: anyone with a hematocrit of 52% or higher, and anyone with a known allergy to NAD. If you take a GLP-1/GIP medication that already contains a small amount of nicotinamide riboside, you can receive NAD+ as part of that prescription but not as a separate standalone prescription. Your provider confirms which applies.

Is NAD+ FDA-approved?

No. NAD+ injections offered by telehealth companies are compounded, and compounded medications are not FDA-approved. FDA states that it does not verify the safety, effectiveness or quality of compounded drugs before they are marketed. On FDA's list of bulk substances nominated for 503A compounding (updated May 14, 2026), nicotinamide adenine dinucleotide is in Category 1, substances under evaluation. That is not an approval and not a finding that NAD+ works.

NAD+ injection cost at Gala

NAD+ at Gala is from $149 a month for a 28-day supply, or $119 a month on the 3-month plan. The provider visit and shipping are included, and you can cancel anytime. You are charged at checkout, a licensed provider reviews before anything ships, and if they cannot prescribe for you, you are refunded in full. The program is cash-pay, with no insurance needed.

Frequently asked questions

What are the benefits of NAD+ injections?

NAD+ is essential for energy metabolism and DNA repair, and raising NAD+ levels is achievable. But no published trial has measured health outcomes from injected NAD+, and a 2026 systematic review called the effectiveness of NAD+ boosting for anti-aging or wellness inconclusive. Benefits you can feel are not yet proven.

How often should you get NAD+ injections?

There is no FDA-labeled schedule, and no published trial has set one for subcutaneous NAD+. Frequency and dose are a clinical decision. At Gala, a licensed provider confirms your dosing before anything ships.

Are NAD+ injections better than IV NAD+?

No trial has compared them on outcomes. The only published infusion study we found, a 2019 pilot in 8 healthy men, gave 750 mg over 6 hours and saw no rise in plasma NAD+ for the first 2 hours. Subcutaneous injections take minutes at home instead of hours in a clinic.

Are NAD+ injections better than NMN or NR pills?

They are different compounds and routes. Oral NR and NMN reliably raise NAD-related markers in trials, with mixed effects on outcomes. Injected NAD+ has no published outcome trials, so results from pills cannot be assumed to apply.

Are NAD+ injections FDA-approved?

No. NAD+ injections from telehealth providers are compounded, and compounded medications are not FDA-approved. FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed.

How much do NAD+ injections cost?

At Gala, NAD+ is from $149 a month for a 28-day supply, or $119 a month on the 3-month plan, with the provider visit and shipping included. If a provider cannot prescribe for you, you are refunded in full.
