What is NAD+?
You may have never heard of NAD⁺, but this tiny molecule is working hard inside every cell in your body — right now. It's like a behind-the-scenes helper that keeps you energized, healthy, and resilient as you get older.
What is NAD⁺?
NAD⁺ (short for Nicotinamide Adenine Dinucleotide) is something your body needs to turn food into energy your cells can use. Think of it as a spark plug for your body’s engine. Without NAD⁺, your cells can’t do their job — and you wouldn’t feel your best.
Why is NAD⁺ important?
Here are some of the things NAD⁺ helps your body with every single day:
-
It gives your body energy
Your cells turn food into fuel using NAD⁺. That fuel powers everything — from your heartbeat to your brain activity. -
It repairs your DNA
Your body is constantly fixing small bits of damage inside your cells. NAD⁺ helps repair DNA and keeps your cells strong and healthy. -
It helps control body functions
NAD⁺ helps manage things like aging, inflammation, and your sleep-wake cycle. It does this by supporting special proteins called sirtuins that help keep your body in balance. -
It supports your immune system
When your body is under stress or fighting illness, NAD⁺ helps your immune system respond and recover.
What happens as we get older?
As we age, our NAD⁺ levels naturally go down. This may be one reason why we start to feel more tired, heal more slowly, and face more health problems over time.
That’s why scientists are studying how we can support or boost NAD⁺ levels — especially in older adults.
Can supplements help?
Some researchers are looking at special forms of vitamin B3 that your body can turn into NAD⁺. Two examples are:
-
NR (Nicotinamide Riboside)
-
NMN (Nicotinamide Mononucleotide)
These supplements are being studied for how they may support energy, brain function, and healthy aging.
In summary
NAD⁺ may be tiny, but it does a big job.
It gives you energy, helps repair your body, supports your immune system, and may help you stay healthier as you age.
Keeping your NAD⁺ levels strong might be one of the keys to feeling good — no matter your age.
