NAD+: Separating the Science From the Hype

NAD+ is one of four wellness injections offered at Arkatiea Aesthetics & Wellness, alongside Methylated B12, the Tri-Immune Injection, and Glutathione. It's also the one most closely tied to the "longevity" conversation — a genuinely interesting area of science that's still very much in progress.

What NAD+ Actually Is

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every cell of the body. According to a Cleveland Clinic naturopathic medicine specialist, NAD's primary role is energy production — helping turn the food you eat into usable fuel — though it's involved in many processes throughout the body, including DNA repair and cell signaling. This part of the science is well established and isn't in dispute.

Does NAD+ Really Decline With Age?

This is where the popular narrative gets ahead of the data. It's often stated as settled fact that NAD+ drops dramatically with age, but a 2025 review in Nature Metabolism found that evidence for an age-related decline in NAD+ levels in humans has actually been consistently observed in only a limited number of studies — a more cautious conclusion than the confident claims you'll often see in wellness marketing. That doesn't mean the decline isn't real; it means the human evidence for it is thinner than commonly assumed.

What the Research Actually Shows

The same Nature Metabolism review found that while preclinical studies support NAD+ precursor supplementation as a promising strategy, human clinical trials have shown limited efficacy so far. Cleveland Clinic's own overview strikes a similarly measured tone, noting that research in this area is still developing.

Worth knowing: Almost all of the human clinical research on NAD+ has studied oral precursor compounds (like nicotinamide riboside or nicotinamide mononucleotide) rather than direct NAD+ injections. Animal studies showing lifespan extension and improved cellular aging markers are genuinely promising — but as of now, no human trials have demonstrated anti-aging effects specifically from NAD+ injections, and reports of improved focus or energy from injections remain largely anecdotal rather than confirmed in controlled studies. That's a meaningfully different evidence picture than "NAD+ reverses aging," even though the underlying cell biology is real.

Who It Tends to Be a Good Fit For

NAD+ tends to appeal most to clients already interested in the broader longevity and cellular-health space, who understand they're trying something with a promising biological rationale and early human data — not a proven anti-aging treatment. It's a reasonable thing to be curious about; it's just worth going in with accurate expectations about where the science currently stands.

What to Expect

The NAD+ Injection is administered as a quick intramuscular shot, typically taking just a few minutes with no downtime. It can be booked on its own or added to another appointment, and is often chosen by clients focused on longevity-minded wellness support.
