NAD+ Injections: What They Are, What the Science Says, and What to Expect

Quick answer: NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential to cellular energy production and DNA repair that naturally declines with age. NAD+ injections aim to support cellular energy and recovery. The evidence base is still developing — human trials confirm NAD+ precursors are safe and raise cellular NAD+ levels, with modest metabolic benefits, though long-term healthspan effects remain unproven. FaroRx offers NAD+ injections starting at $179/month.

NAD+ has become one of the most talked-about names in the longevity world — and also one of the most hyped. Here’s a grounded look at what it is, what it isn’t, and what a reasonable set of expectations looks like.

What NAD+ actually does

NAD+ is a coenzyme found in every cell in your body. It’s central to two critical processes:

• Cellular energy production — helping convert food into usable energy in your mitochondria
• DNA repair — supporting enzymes that fix cellular damage over time

NAD+ levels decline naturally as you age, and that decline is accelerated by things like poor sleep, high stress, alcohol use, and prolonged sun exposure. That decline is part of why NAD+ has become closely tied to conversations around aging and cellular health.

What the evidence actually shows (as of 2026)

It’s worth being direct here, because there’s a real gap between marketing enthusiasm and clinical evidence. Human trials of NAD+ and its precursors have consistently shown they’re safe and effectively raise NAD+ levels in the body, with modest measurable metabolic benefits. What hasn’t been established yet is whether raising NAD+ levels translates into a longer or meaningfully healthier lifespan in humans — that research is still ongoing.

That doesn’t mean NAD+ is without value; it means the honest framing is “supports cellular energy metabolism,” not “reverses aging.” Longevity researchers generally recommend treating it as one piece of a broader approach — alongside exercise, sleep, and other well-established healthy-aging habits — rather than a stand-alone solution.

How it’s typically administered

NAD+ has traditionally been delivered via IV infusion, but subcutaneous injection has become a more accessible, lower-hassle option that doesn’t require an infusion chair or clinic visit. FaroRx’s NAD+ protocol is a subcutaneous injection you can do at home.

How to get it through FaroRx

1. Take the health quiz — covers your goals and health history.
2. Meet your provider online — a licensed U.S. provider reviews your intake and builds a longevity-focused dosing plan.
3. Get it shipped monthly — free, discreet delivery, with care team messaging along the way.

Pricing: $179/month, with quarterly ($479) and six-month ($969) options.

What to expect

Many patients report improved focus, energy, and recovery, particularly with consistent use over weeks to months. As with any longevity-oriented treatment, individual response varies, and NAD+ is best understood as a supportive addition to — not a replacement for — sleep, exercise, and nutrition fundamentals.

Frequently Asked Questions

What does NAD+ do for the body? NAD+ is a coenzyme essential to converting food into cellular energy and supporting DNA repair processes that decline with age.

Does NAD+ actually slow aging? Human research confirms NAD+ supplementation is safe and raises cellular NAD+ levels with some metabolic benefits, but evidence that it extends healthspan or lifespan in humans is still developing. It’s best approached as cellular energy support, not a proven anti-aging cure.

Is NAD+ injection better than an IV infusion? Both raise NAD+ levels. Injections are generally more convenient — no infusion chair or clinic visit required — while IV infusions can deliver a larger dose in a single session. Your provider can help you decide what fits your goals.

How often do I need a NAD+ injection? FaroRx’s protocol is dosed on a longevity-focused schedule set by your provider, typically administered weekly.

Are there side effects to NAD+ injections? Reported side effects are generally mild — some people notice temporary flushing, warmth, or injection-site discomfort. Your provider will review what’s typical based on your health history.

Is it right for you?

If you’re interested in supporting cellular energy and recovery as part of a broader healthy-aging routine — and want a grounded, evidence-aware approach rather than hype — NAD+ is worth discussing with a provider.
