If you've scrolled past ads for NAD "drip bars" or heard a podcaster rave about NAD infusions for energy and anti-aging, you're not alone. Clinics now charge hundreds of dollars per session for intravenous NAD+, promising everything from sharper thinking to slower aging. But almost all of the promising research on NAD+ boosting comes from animal studies or small human trials using oral supplements, not the IV injections being sold at wellness clinics. Direct IV NAD+ in healthy humans is scarcely studied.

It’s not often that a molecule catapults from obscure biochemical pathways to center stage in the world of anti-aging. But nicotinamide mononucleotide (NMN) has done exactly that. Once studied mostly in academic labs, NMN is now the headline ingredient in countless supplements that promise energy, cellular rejuvenation, and even longer life.
Why the buzz? NMN is a precursor to NAD+, a compound critical to cellular energy production and metabolic health. As we age, NAD+ levels naturally decline, and this drop is linked to everything from fatigue and insulin resistance to neurodegeneration. Supplementing with NMN, the thinking goes, could restore NAD+ levels and slow the tide of aging. But there’s a catch. Just because a molecule has promise doesn’t mean any product containing it will deliver results.

When healthy adults received a six-hour intravenous NAD+ infusion, their plasma NAD+ was rapidly cleared. What showed up instead were metabolites in the urine, proving the body processed it but offering no tested clinical benefit. That's a significant gap between what NAD shot marketing suggests and what the research actually supports.
NAD+ itself is genuinely important. It's central to energy production, redox balance, DNA repair, and the activity of sirtuins (enzymes involved in aging and metabolism). Levels decline with age and in conditions like heart failure and neurodegeneration. The logic of boosting it makes sense on paper. The problem is that the leap from "NAD+ matters" to "injecting it helps you" skips over most of the science.

It is hard to visit a health store or listen to a biohacking podcast without encountering three letters: NAD. Touted as the molecule of youth, nicotinamide adenine dinucleotide (better known as NAD+) has exploded into public consciousness. It promises everything from sharper memory and faster metabolism to a longer life.
This hype is not without basis. NAD is essential for life. It fuels hundreds of enzymatic reactions, supports DNA repair, and powers our cellular energy factories. Moreover, NAD+ levels decline as we age, a drop linked to metabolic disorders, neurodegeneration, and possibly aging itself.
