NAD+ and Cellular Energy
What It Is, Why It Declines With Age, and What People Do About It
The Molecule of Longevity
If you follow the world of longevity and “anti-aging,” you’ve likely heard about NAD+. It is currently one of the most talked-about molecules in science, touted by researchers as a cornerstone of cellular health.
But what exactly is it, and why are people suddenly so focused on “boosting” it? Let’s break down the science of cellular energy and why your NAD+ levels matter more than you might think.
What NAD+ Does: The Spark Plug of the Cell
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every single living cell in your body. If your cells were an engine, NAD+ would be the spark plug that allows the fuel to ignite.
It plays two primary roles:
- Energy Metabolism: It helps turn the food you eat into ATP, the energy your cells need to function. Without enough NAD+, your “engine” begins to stall.
- Cellular Repair: NAD+ is the fuel for Sirtuins (often called “longevity genes”) and PARPs, which are enzymes that repair damaged DNA and protect cells from the wear and tear of daily life.
Why Levels Change Over Time
The catch with NAD+ is that our bodies don’t have an infinite supply. Our levels tend to decline naturally as we age—often dropping by as much as 50% by the time we reach middle age.
It’s not just birthdays that drain the tank, though. Modern life can accelerate the decline:
- Chronic Stress: High stress forces the body to use more NAD+ for repair.
- Poor Sleep: Circadian rhythm disruptions interfere with how the body produces and recycles this coenzyme.
- Excessive Inflammation: When the body is in a state of high inflammation, it “consumes” NAD+ at a much faster rate, leaving less for energy and DNA repair.
How People Support Their NAD+ Levels
Several strategies have emerged that may support healthy levels:
- Lifestyle Foundations: High-intensity exercise and intermittent fasting can naturally “nudge” the body into producing more NAD+.
- Nutritional Support: Foods rich in Vitamin B3 provide the raw materials the body needs.
- Supplements: Oral precursors (like NMN or NR) are popular for daily maintenance.
- I.V. Therapy: NAD+ I.V. infusions deliver the coenzyme directly into the bloodstream for 100% bioavailability.

What to Expect from an NAD+ I.V. Visit
If you decide to explore I.V. therapy, a session can take anywhere from 2 to 4 hours. Pacing is key to staying comfortable.
- The “NAD+ Sensation”: If the drip goes too fast, you might feel a heavy sensation in your chest or mild headache. Your provider will monitor you and adjust the rate immediately.
- Hydration & Comfort: You can read, work, or nap while your cells get a “recharge.”
Who Should Talk to a Clinician First?
While supporting cellular energy is a goal for many, NAD+ therapy isn’t for everyone. Always consult with a provider if you have an active cancer diagnosis, are pregnant/breastfeeding, or have a history of liver/kidney conditions.
