NAD+ Therapy: What It Is, What It Does, and What the Science Actually Shows

NAD+ has become a major focus in the longevity and wellness world, marketed as everything from an energy booster to an anti-aging breakthrough. The biology behind it is real, but it's worth separating what's well-established from what's still being studied. Here's a balanced look at NAD+ therapy.

What Is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell in your body. It's essential for converting nutrients into cellular energy and supports important processes like DNA repair and cell survival. NAD+ levels naturally decline with age, and lower levels have been linked to reduced cellular resilience and slower DNA repair.

Peptide Dispensary offers NAD+ as a 300mg pen (per 3ml pen), dosed two to three times per week, with a recommended maximum of 50mg to 100mg per week.

How NAD+ Supplementation Is Thought to Work

The theory behind NAD+ therapy is that replenishing declining levels could support mitochondrial function, energy production, and cellular repair. Much of the most compelling evidence for these benefits comes from animal studies, which have shown improvements in mitochondrial health, exercise performance, and markers of inflammation.

Human research is still catching up. It's important to know that, as of current research, there are no large-scale outcome trials specifically evaluating injectable or IV NAD+ for anti-aging or general wellness in humans, and NAD+ isn't expected to enter cells fully intact, meaning the 'direct cellular refill' framing used in some marketing oversimplifies the biology. We think it's important to be upfront about this: the excitement is grounded in real cellular biology, but the human clinical evidence for injectable NAD+ specifically is still developing.

How It's Used

NAD+ is typically administered as a subcutaneous injection, two to three times weekly, within a recommended weekly maximum. Your prescriber will help you determine an appropriate schedule based on your goals and how you respond.

What People Use NAD+ For

•       Supporting general energy and vitality as part of a wellness routine

•       Complementing recovery and cellular health protocols

•       Supporting healthy aging routines alongside diet, exercise, and sleep

Setting Honest Expectations

We'd rather be upfront than oversell this: if you're considering NAD+ therapy, it's worth going in with tempered expectations, some people report noticeable improvements in energy and mental clarity, but individual response varies widely and isn't yet well quantified in controlled human trials. NAD+ is best approached as one component of a broader wellness routine, alongside sleep, nutrition, and exercise, rather than a standalone solution. A conversation with your prescriber can help you weigh the current evidence against the cost and decide whether it fits your goals.

Frequently Asked Questions

Does NAD+ therapy really slow aging?

The underlying biology, NAD+'s role in cellular energy and repair, is well established, but robust human trials on injectable NAD+ for anti-aging specifically are still limited. Most of the strongest evidence so far comes from animal studies. Approach marketing claims with healthy scepticism and discuss realistic expectations with your prescriber.

How is NAD+ administered?

As a subcutaneous injection, typically two to three times per week, up to a recommended weekly maximum set by your prescriber.

Are there side effects with NAD+ injections?

Reported effects are generally mild, such as injection site reactions, but you should discuss your full health history with your prescriber before starting.

Is NAD+ regulated as an approved anti-aging treatment?

No. NAD+ is not an approved anti-aging drug. It's dispensed at Peptide Dispensary as a compounded preparation, and should be considered within a broader, medically supervised wellness plan rather than a standalone cure.
