What You Need to Know Before Trying NAD⁺ to Slow Aging
Why I am Sharing This
The science around aging is evolving fast, and with it comes a wave of new supplements and claims. One that keeps coming up is NAD⁺, a molecule tied to energy, DNA repair, and the aging process. I had heard about NAD⁺ and the fact that it may slow aging, but I didn’t know much about it, so when this video by SciShow came up in my feed, I watched and it brought a little more clarity.
Here is a short summary of the video and a cheat sheet with the points I found most useful. The video is embedded at the bottom of the page so you can watch it without leaving this site. Below that, you’ll find links to related articles.
Video Summary
This video by SciShow explains what NAD⁺ is, how it supports cellular health, and why its decline with age has become a focus in longevity research. It introduces two supplements (NR and NMN) that may help restore NAD⁺ levels, potentially improving insulin sensitivity, inflammation markers, and overall metabolic function. The video also discusses natural ways to maintain NAD⁺, including exercise and calorie restriction, and critiques the growing wellness trend of costly NAD⁺ infusions. Rather than promising longer life, the focus is on improving healthspan, the years you remain healthy and independent.
Cheat Sheet
Can NAD+ Truly Slow Aging?
Based on the video by SciShow
What Is NAD⁺?
NAD⁺ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells.
It supports DNA repair, mitochondrial function, and inflammation control.
NAD⁺ levels decline with age, which may contribute to fatigue, reduced cell repair, and age-related diseases.
Why Boost NAD⁺?
Scientists believe that restoring NAD⁺ levels may help slow cellular aging.
It's not about living longer, but about staying healthy longer and extending your healthspan.
How to Boost It:
Supplements (Precursors):
NR (Nicotinamide Riboside) and NMN (Nicotinamide Mononucleotide) are easier to absorb than NAD⁺ itself.
NR has been shown to raise NAD⁺ levels in older adults without major side effects.
NMN improved insulin sensitivity in postmenopausal women with pre-diabetes.
A 2022 meta-analysis showed potential benefits for cholesterol and inflammation, though results were modest.
Natural Methods to Boost NAD
Regular exercise
Calorie restriction and intermittent fasting
Avoiding smoking and managing chronic stress
Industry Trends & Cautions
NAD⁺ IV drips are promoted in luxury wellness centers and celebrity circles.
These treatments are costly and not backed by strong clinical evidence.
Supplements are widely available but not regulated by the FDA.
Bottom Line
NAD⁺ boosters are promising but still early-stage.
Focus first on proven strategies: diet, movement, and stress management.
These supplements may support healthy aging, but they’re not a substitute for lifestyle choices.
