A smiling middle-aged woman with a water bottle on a walk in the park — NAD+ benefits, cellular energy and the anti-aging supplement trend

NAD+ is a molecule your cells can’t produce energy without, and you have less of it as you age. We look at what NAD+ is, which NAD+ benefits and side effects are proven in humans, what’s known about IV drips and how to support cellular energy without trendy vials.

Questions and answers

What is NAD+?
It’s a molecule found in every cell that helps turn food into energy: it carries electrons to the mitochondria, where ATP is produced. NAD+ levels naturally decline with age.
What are the benefits and side effects of NAD+?
NAD+ precursor supplements raise its levels in the blood, but benefits for energy or “rejuvenation” in humans haven’t been proven yet. Possible side effects include nausea, headache and digestive upset, and niacin-based supplements can cause flushing.
What are NAD+ IV drips used for?
They’re promoted as a way to “rejuvenate” and boost energy. But a large 2026 review didn’t find a single suitable controlled study of NAD+ IV drips for these purposes, so any procedures should only be discussed with a doctor.
How can you boost NAD+ naturally?
Experts advise regular movement and eating foods that give your body the building blocks it needs: poultry, fish, eggs, dairy, whole grains and nuts. Sleep and moderation with alcohol matter too.
