By last spring, Maria felt the afternoon slump hit so hard she skipped her usual walk and stayed on the sofa instead. A friend told her that age, stress, and long workdays might be draining a tiny helper molecule in her cells named NAD+.

Why energy feels lower after 40

NAD+ is a helper that turns food and oxygen into fuel inside each cell. Levels fall as the years pass. Social media is full of people talking about NAD+ capsules and drips, and this plain summary from Health.com shows how big that trend has become while also stressing limits and safety questions. See how NAD supplements took over social feeds.

What NAD+ does in your body

You can think of NAD+ as a pass that helps your cells run repair and clean up jobs. It helps enzymes fix daily wear and tear in DNA and support steady energy in brain and muscle. When levels drop, that system may struggle, so many studies in people past mid forties test ways to restore it.

Supplements that raise NAD+

Most shelf NAD+ helpers are forms of vitamin B3 such as nicotinamide riboside and nicotinamide mononucleotide. Human trials show that these can raise blood NAD+ in adults. This guide explains in simple language how nicotinamide riboside works, plus what early human research has seen so far. Plain language guide to nicotinamide riboside.
A large review in 2024 pulled together human trials of nicotinamide mononucleotide and found that doses used in studies raised blood NAD+ and looked safe for healthy adults over weeks to months, while asking for longer tracking. Research round up on NMN in adults.

A calm way to test this

If you are curious, treat NAD+ boosters as a small experiment, not a magic fix. Start with basics first: regular movement, steady meal times, light strength work, and sleep that feels regular. Then talk with your doctor about whether a low dose NR or NMN supplement fits your health history and medicines, and agree on a time frame to review how you feel. Be wary of high price IV drips or big promises, and stick with clinics and brands your doctor trusts. NutritionFacts.org has a short video review that lays out possible upsides and safety questions in plain language. Short video tour of NR risks and rewards.
