NAD+ IV Therapy, considered.
NAD+ is essential biology with a complicated marketing footprint. The molecule is real and important. The IV protocols sold around it are often promoted ahead of the data. A measured assessment is overdue.
What NAD+ does.
Nicotinamide adenine dinucleotide is a coenzyme present in every cell, central to energy metabolism, DNA repair, and sirtuin activity. NAD+ levels decline with age. Restoring them, in animal models, produces measurable health effects.
Whether IV NAD+ at the doses used clinically (250–1,000 mg per session) measurably restores tissue NAD+ in humans, and whether that translates to clinical benefit, is an open question. Plasma NAD+ rises during infusion. Tissue penetration and durability are less well-characterized.
What the evidence supports — and doesn't.
Strongest data: small studies and case reports for chronic fatigue, addiction recovery (long-protocol, 8–10 days inpatient), Parkinson's-related symptoms. Plausible but underpowered: cognition, energy, exercise tolerance.
Marketing claims that outpace evidence: anti-aging, lifespan extension, dramatic cognitive enhancement. NAD+ may participate in those processes — that is not the same as IV NAD+ producing those outcomes at clinical doses.
Oral precursors as the alternative.
Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are oral NAD+ precursors. Bioavailability studies show measurable plasma NAD+ elevation. Cost is dramatically lower ($30–$80/month vs $300+/infusion).
For a longevity-oriented patient curious about NAD+ status, oral precursors plus periodic blood NAD+ measurement is more cost-effective than IV protocols. IV is reasonable for acute interventions (recovery from illness, jet lag, post-procedure) where the goal is short-term plasma elevation.
Common questions.
What does an infusion feel like?
Most patients experience facial flushing, chest pressure, and mild nausea during fast infusions. Slowing the drip resolves these. A 500 mg session typically runs 2–4 hours.
How often should I do it?
Protocols vary widely. Common: a loading course of 4–6 sessions over 2–3 weeks, followed by monthly maintenance. There is no consensus protocol. Ask the clinic for their reasoning, not just their schedule.
Is it safe?
At standard clinical doses, adverse events are rare and minor. Long-term safety at very high cumulative doses is undefined. Most clinicians cap individual sessions at 1,000 mg and avoid daily protocols.
Will I feel different?
Subjective improvements in energy, mood, and clarity are commonly reported, especially in patients with low baseline NAD+ (chronic fatigue, post-viral). Healthy patients with normal energy may notice nothing.
IV vs NMN/NR pills?
Pills raise NAD+ measurably, slowly, cheaply. IV raises it acutely and dramatically, expensively. Both are reasonable. Choose based on goal: chronic optimization (pills) vs acute intervention (IV).
