We’re all getting older, and we’re all looking for ways to preserve our youth, feel fresh, live healthier, and enjoy a good life longer.
And that’s where NAD+ comes in.
In the hustle of daily life, you juggle a lot of balls. You have work, you have family, you have systemic issues, you have the everyday grind that can leave you short on sleep and long on feeling bleh.
Whether you suffer from persistent fatigue or endless brain fog, or you’re just not feeling as good as you could, ‘feeling old’ will hit us all from time to time. Eventually, Father Time is always victorious.
But here’s the thing.
The latest science now points to a key player in slowing our biological and cellular aging. NAD+, or nicotinamide adenine dinucleotide, is a vital coenzyme that powers our mitochondria.
If you’re looking to restore vitality, sharpen the mind, and support long-term health in ways that are real, not fiction, you’ve come to the right place…

The main reason NAD+ is so essential is that it helps convert glucose into usable energy, in the form of ATP. In this form, your body can effectively repair DNA while even keeping your longevity proteins – sirtuins – active.
Because animal studies suggest that NAD+ levels can drop by up to half in middle age, and human studies report age-related declines in NAD+ levels in the skin, brain, liver, and blood, keeping them fresh is key. Any improvements mean less sluggish mitochondria, less oxidative stress, and less metabolic slowdown.
For many Black adults, this is especially important. Why? Because decline can feel amplified in Black adults, triggered by higher levels of cortisol and inflammation, and thereby higher rates of cellular wear and tear. Researchers often call this ‘weathering’ and attribute it to increased biological aging in Black women in particular.
Whether it’s environmental factors like pollution in urban neighborhoods, food deserts, or limited socioeconomic opportunities, these stressors take their toll over time. These challenges are reflected in the fact that Black communities are disproportionately affected by high blood pressure, diabetes, and obesity.
This isn’t just ‘getting older.’
It’s an indirect or even direct result of low NAD+ levels, leading to less supply for your neurons and muscles. As a result, the mental haze and physical drain you feel become greater and greater, mistaken by many professionals as just normal aging.
Fortunately, proper NAD+ intake can help offset many of these effects.

Understanding the Science-Backed Benefits
When you replenish your NAD+ levels, you’re basically ramping up your mitochondrial function. And, as you may know, mitochondria are essentially the powerhouses of your cells. Without consistent, robust mitochondrial function, you could easily end up exhausted.
Here’s the good thing. When you boost NAD+, you’re boosting ATP production for potential energy gains. This is why many users report less fatigue, better exercise recovery, and improved daily vitality. On the brain side, NAD+ helps support healthy neurons. It repairs DNA and reduces oxidative stress – one of the main reasons people swear that it clears up their brain fog.
But the possible benefits don’t stop there. Metabolically speaking, NAD+ enhances insulin sensitivity and supports healthy blood pressure regulation. Small human trials have shown modest reductions in systolic blood pressure, improved vascular function, and reduced arterial stiffness.
Again, this is why NAD+ can be a game-changer in Black communities. Given the higher rates of cardiovascular conditions among Black adults, improved NAD+ levels may yield greater heart and vascular health while addressing the physical and mental fatigue associated with these issues.
Are larger-scale trials still needed? Absolutely, but given the emerging evidence and plenty of now-supported anecdotes, it doesn’t hurt to have some healthy optimism.
Of course, part of success with NAD+ comes down to your unique physiology and brain health.
Your NAD+ Protocol Options
There are various options to consider as you look into the potential of NAD+. One of those is the infusion option. If you’ve never heard of it, IV therapy essentially delivers NAD+ directly into the bloodstream with near-100% bioavailability.
Your typical session includes 500-1000 mg over several hours. Some people report noticeable energy and clarity lifts within just days.
But there are some downsides. Firstly, it’s costly, and it’s time-intensive. In some cases, it may cause temporary discomfort, such as chest tightness, but the good news is that many clinics now offer shorter IVs for better tolerance.
Research on intravenous NAD+ also remains limited. In one small study, a 6-hour NAD+ infusion increased NAD+ metabolites in blood and urine, showing that IV NAD+ can enter the body and affect NAD+ metabolism. Another pilot study of 15 healthy men found that 750 mg of IV NAD+ daily for 5 days led to greater improvements on several cognitive tests than saline. Notably, some of the researchers had a financial stake in IV NAD+ therapy, so the results should be interpreted cautiously.
Besides the intravenous option, another option is oral precursors that can help your body make more NAD+, such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN).
These are known as vitamin B3 derivatives; they’re readily available and convert efficiently to NAD+ inside your cells. These options may increase NAD+ levels in your blood more than other forms, particularly improving outcomes related to metabolism, insulin sensitivity, and neuroprotection.
Just make sure you look for quality brands that have undergone third-party testing.
Your typical doses include 300-1000mg daily. And don’t forget: the positive effects may build over weeks, so you should definitely combine NAD+ with lifestyle tweaks too. Supplements work best alongside habits that naturally preserve or boost NAD+.
For instance, exercise. HIIT and resistance training are especially powerful in activating NAD+ pathways and sirtuins, your longevity proteins. Then there’s nutrition. Eating and working out are equally important because you can’t do one well without the other. For nutrition, focus on foods rich in precursors, like wild-caught fish, lean meats, dairy, mushrooms, avocados, and whole grains.
Intermittent fasting or time-restricted eating also elevates your NAD+ levels naturally.
And of course, last but not least, you need to prioritize sleep and stress management. Deep rest is critically important because that’s where the repair happens. The cool thing is, when your NAD+ levels are higher, your circadian rhythms are more natural. So, they go hand-in-hand.
Because at the end of the day, this isn’t some elitist science — it’s empowerment. These protocols and lifestyle changes are extremely accessible, no matter your budget or circumstance. If you’re seeking a smart, science-driven tool for vitality, NAD+ may be a helpful piece of the puzzle.
For Black communities, disproportionately affected by chronic inflammation, NAD+ may just be the game-changer people have been seeking…
