NAD+ IV therapy claims: what the evidence actually supports

What did @ohmichellelee actually say?

She made three core claims: NAD is "a molecule found in every cell, fueling the mitochondria," that NAD levels "naturally decline" with age, and that monthly IV therapy personally helps her "brain fog, energy levels, sleep score, and mood." She also plugged Next Health, the clinic where she gets her drips. The framing is personal testimony mixed with basic biology, which is a combination that tends to blur the line between anecdote and evidence. Credit where it's due: she didn't promise NAD IV therapy would cure anything. She kept most of it in first-person. But personal results presented over b-roll of IV bags carry weight with viewers who may not distinguish "this worked for me" from "this is proven to work."

Does the science back this up?

The basic biology is solid. The personal claims are plausible but unverifiable. The clinical evidence for IV NAD+ in healthy adults is thin. NAD+ (nicotinamide adenine dinucleotide) is genuinely a coenzyme present in every cell and central to mitochondrial energy metabolism. Age-related NAD+ decline is well-documented in animal models and increasingly in human tissue samples (Yoshino et al., 2018, Cell Metabolism). Where things get complicated is the jump from "NAD declines with age" to "infusing NAD+ intravenously reverses that decline in meaningful ways." Most human clinical trials have used oral precursors like NMN or NR, not IV NAD+ directly. A 2023 review in Nature Aging noted that while NAD+ precursor supplementation shows promise, the bioavailability advantage of IV over oral delivery in humans has not been cleanly established. The studies showing dramatic cognitive or energy benefits in healthy, non-deficient adults simply don't exist yet at the scale influencers imply.

What did they get wrong (or right)?

The biology she described is largely accurate. The implication that monthly infusions are a necessary maintenance protocol for a healthy adult is where the evidence doesn't keep up. She got it right that NAD+ fuels mitochondria and that levels drop with age. Those are textbook facts supported by research going back decades, including Guarente's work at MIT. What she glossed over: IV NAD+ therapy is expensive (often $500-$1,000 per session), not covered by insurance, and the clinical evidence base for subjective outcomes like brain fog and mood in otherwise healthy people is primarily anecdotal or from small, uncontrolled studies. There's also a real question about whether the bioavailability of IV NAD+ translates to the specific tissue improvements people report. A 2022 pilot study by Brakedal et al. in Cell Metabolism showed IV NAD+ raised blood NAD+ levels, but connecting that to mood or sleep scores in healthy adults is a significant leap.

What should you actually know?

NAD+ IV therapy is not approved by the FDA for anti-aging or cognitive enhancement. It is used in some clinical settings for addiction treatment and is being actively studied. If you're considering it, there are real things to weigh. First, the side effect profile during infusion is not trivial. Many people experience nausea, flushing, and chest tightness during administration, which is why it requires slow infusion rates. Second, the research on oral NAD+ precursors (NMN, NR) is further along than IV-specific research for general wellness. Third, "I feel better after getting one" is not a controlled observation. Travel disrupts sleep, hydration, and routine. Any intervention given at a wellness clinic, including saline, can produce a perceived benefit. That doesn't make the experience fake, but it does make it hard to attribute to NAD+ specifically. If you have a clinician you trust, this is worth a real conversation, not a TikTok consultation.
