If you’ve been exploring the world of longevity, energy optimization, or anti-aging science, there’s a good chance you’ve come across NAD+. But what exactly is it — and why is everyone from Harvard scientists to health influencers talking about it?
Let’s break it down in plain English.
🧬 What Is NAD+?
NAD+ (short for Nicotinamide Adenine Dinucleotide) is a molecule found in every cell of your body. Think of it like the spark plug that helps your cells produce energy. Without NAD+, your body wouldn’t be able to convert the food you eat into usable fuel.
But that’s just the beginning.
NAD+ also plays a major role in:
-
DNA repair
-
Cellular metabolism
-
Brain function
-
Skin health
-
Healthy aging
In short, NAD+ helps keep your cells functioning at their best.
⏳ Why Do NAD+ Levels Decline with Age?
One of the key reasons NAD+ has become a focus in the health world is that your natural levels decline significantly as you get older — starting as early as your mid-20s.
By the time you hit your 40s or 50s, NAD+ production may be less than half of what it was in your youth. Scientists believe this drop may be linked to many common signs of aging, including:
-
Lower energy
-
Slower recovery
-
Brain fog
-
Wrinkles and skin dullness
That’s why boosting or supporting your NAD+ levels has become a go-to strategy for people looking to optimize how they age.
⚙️ How Does NAD+ Work in the Body?
At a basic level, NAD+ works like this:
-
You eat food → Your body breaks it down into glucose and fatty acids.
-
NAD+ helps convert those molecules into ATP (your cells' energy source).
-
NAD+ also supports enzymes called sirtuins, which are involved in cellular repair and longevity pathways.
So it’s not just about energy — NAD+ is deeply tied to how your body repairs itself and maintains balance as you age.
🌿 Can You Boost NAD+ Naturally?
Yes — there are both lifestyle habits and supplements that can help support healthy NAD+ levels.
Here’s what research and anecdotal evidence suggest:
🥗 Diet:
-
Eating a diet rich in niacin (Vitamin B3) — found in turkey, chicken, and tuna — may support NAD+ production.
-
Intermittent fasting and caloric restriction have also been linked to increased NAD+ activity in animal studies.
💪 Lifestyle:
-
Exercise is a powerful NAD+ booster. Even moderate activity like walking or yoga may help.
-
Quality sleep and stress management play a key role in preserving NAD+ levels.
💊 Supplements:
Some compounds are being studied for their ability to support or replenish NAD+ in the body:
-
Nicotinamide
-
Coenzyme Q10 (CoQ10)
-
NAD+ precursors like NMN or NR
These ingredients are often found in modern longevity supplements — including our own RE:SKIN blend — formulated to support healthy NAD+ function from the inside out.
🔍 What About Safety?
NAD+ is naturally produced in the body, and many of the ingredients used to support it are considered well-tolerated. Still, it’s always smart to consult your doctor before starting any new supplement — especially if you’re on medication or managing health conditions.
🧠 Final Thoughts: Should You Care About NAD+?
If you're someone who values long-term energy, brain function, and aging gracefully — yes.
NAD+ isn’t a magic bullet, but it is one of the most important molecules you’ve probably never heard of. Supporting your body’s natural NAD+ levels can be a powerful step toward better health, better skin, and better aging.
