NAD+ IV Therapy for Energy and Recovery: What the Evidence Shows

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell, and it is marketed for energy, recovery, and anti-aging effects, but it is not FDA-approved for any of those uses, and large, well-controlled trials showing IV NAD+ infusions improve energy are lacking. The FDA has received reports of adverse reactions after NAD+ injectable use. At Zest 4 Wellness in Columbia, Maryland, an infusion is therefore offered as part of physician-supervised care after a medical evaluation and candidacy review, never as a walk-in wellness product.

What NAD+ is

NAD+ is a coenzyme found in every cell of the body. It plays a central role in cellular energy production and in processes like DNA repair and cellular signaling. Levels of NAD+ naturally decline with age, which is why supplements and infusions marketed around aging and energy have grown popular. Whether raising NAD+ through an IV infusion produces meaningful clinical benefits remains an open question rather than an established fact.

How IV NAD+ is given

IV NAD+ therapy delivers the compound directly into the bloodstream through a vein over a set period, usually under observation. Because it bypasses digestion, it reaches tissues quickly, but that same route carries the risks shared by all IV infusions, plus reactions tied to the product itself.

What the current evidence shows

• The FDA has stated that NAD+ injectables are not FDA-approved and has reminded sterile compounders about adverse event reports after NAD+ injectable use, including severe chills, shaking, vomiting, and fatigue.
• A 2024 systematic review of NAD in clinical conditions found that the included studies reported side effects, and it notes the absence of large placebo-controlled trials establishing benefit for energy or wellness uses.
• A real-world tolerability pilot study found that IV NAD+ infusions were associated with moderate to severe side effects in a notable portion of recipients.
• The FDA has also sent advisory and warning letters characterizing certain marketed NAD+ products as unapproved new drugs sold in violation of federal law.

Why supervision matters

An IV infusion is a medical procedure. Evaluating your history, confirming candidacy, screening for contraindications, and monitoring the infusion are all steps that reduce, though cannot eliminate, risk. A clinic worth visiting talks openly about what the evidence does and does not support, and it does not promise that a single drip will fix fatigue that may have causes like thyroid, sleep, or stress issues.
