You may have never heard of NAD+ before, but this little molecule plays a big role in how your body functions—and how you feel as you get older. NAD+ (short for nicotinamide adenine dinucleotide) is a coenzyme found in every cell in your body. It helps your cells produce energy, repair DNA, and maintain healthy brain and muscle function. Simply put, NAD+ helps keep your body running smoothly.
But here’s the catch—your levels of NAD+ naturally decline as you age. And as those levels drop, it can lead to noticeable changes in how your body feels and functions. Let’s take a closer look at how NAD+ declines over time, what that means for your health, and the options you have to boost those levels and feel your best. Wondering how often NAD injections are needed? Most people start with weekly sessions and adjust based on their energy levels and wellness goals.
What Is NAD+ and Why Does It Matter?
NAD+ works like a fuel helper in your cells. It helps turn food you eat into energy your body can use. It also supports the processes that repair cell damage, manage inflammation, and regulate your sleep-wake cycle (circadian rhythm). It’s involved in over 500 biological processes.
When your NAD+ levels are high, your cells function better. You may feel more energetic, mentally sharp, and physically resilient. But when levels decline, things start to slow down—literally.
Why NAD+ Levels Drop With Age
NAD+ levels peak in your youth and begin to decrease as early as your 30s. By the time you’re in your 60s, your NAD+ levels may be less than half of what they were in your 20s. Several factors contribute to this decline:
- Increased demand for NAD+: As your body ages, more NAD+ is needed to repair damaged cells and manage stress.
- Less efficient production: Your body becomes less effective at making NAD+ from the nutrients you eat.
- Enzyme activity: Certain enzymes that break down NAD+ become more active as you age, reducing the amount of it available in your cells.
- Chronic inflammation: Known as “inflammaging,” this low-level inflammation that builds over time can also drain your NAD+ reserves.
All of this means that even if you’re living a healthy lifestyle, your body may still be struggling to keep NAD+ levels high.
Signs Your NAD+ Levels Might Be Low
While you can’t test NAD+ levels at home, there are some signs that your body might be running low on it. Common symptoms include:
- Fatigue or low energy
- Slower recovery from exercise
- Brain fog or memory issues
- Poor sleep
- Muscle weakness
- Feeling generally “sluggish” as you age
These symptoms can also be caused by other things, of course, but low NAD+ might be playing a role.
What You Can Do To Boost NAD+ Naturally
The good news is there are ways to support your body’s NAD+ levels—both through lifestyle changes and more targeted therapies. Here are some effective options:
1. Exercise Regularly
Physical activity naturally increases NAD+ levels. High-intensity interval training (HIIT) and resistance training seem especially beneficial. Exercise also reduces inflammation and supports healthy aging overall.
2. Eat a NAD+-Supportive Diet
Some foods help provide the building blocks your body needs to make NAD+. Try to include:
- Fish (like tuna and salmon)
- Chicken
- Whole grains
- Green vegetables (like broccoli and spinach)
- Mushrooms
Avoiding too much processed food and sugar also helps reduce inflammation, which in turn protects NAD+.
3. Try Intermittent Fasting
Fasting or time-restricted eating can boost NAD+ by activating certain proteins (like sirtuins) that rely on NAD+ to work. Fasting gives your body a break from continuously digesting food and encourages it to switch into repair mode, where NAD+ plays a big part.
4. Get Quality Sleep
Good sleep helps regulate many processes in the body, including the production and use of NAD+. Aim for 7–9 hours of sleep to keep your body balanced.
Supplementing NAD+: What About NAD+ IV Therapy?
If you want to take things a step further, there are ways to increase NAD+ more directly. NAD+ Montauk IV therapy has grown in popularity as a way to deliver NAD+ straight into your bloodstream, allowing your body to absorb and use it immediately.
People who get NAD+ IV therapy often report:
- More energy
- Better focus
- Improved mood
- Better recovery after exercise or travel
- A general sense of feeling “recharged”
While the science is still growing, early research and personal experiences show promise. NAD+ therapy is often used as part of wellness routines, anti-aging programs, or even addiction recovery protocols.
There are also oral supplements like NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside), which are NAD+ precursors. These don’t deliver NAD+ directly, but they help your body produce more of it. These can be a good option if you want something more affordable or easy to use at home.
The Bottom Line
NAD+ may not be something you’ve thought about before, but it’s worth your attention—especially if you’re noticing the effects of aging. While it’s normal for NAD+ levels to drop over time, you can take steps to support your body and potentially slow down that decline.
A combination of healthy habits like exercise, a good diet, and proper sleep can make a big difference. If you’re looking for a more immediate boost, NAD+ IV therapy or supplements might help you feel more energized and focused.
