The Rise of NAD+ in the Wellness World
Every so often, a wellness trend emerges that changes our understanding of health and longevity. These trends often gain traction on social media, but some go beyond fleeting popularity to become integral parts of modern health routines. One such trend is the use of NAD+.
NAD+, or nicotinamide adenine dinucleotide, is a molecule found in every cell of the body. It plays a crucial role in energy production, DNA repair, reducing inflammation, and maintaining overall cellular health. While it has been available as a supplement for years, its popularity has surged in recent times, especially within the longevity movement.
This increased interest has been fueled by high-profile figures like Bryan Johnson and Gary Brecka, who have brought attention to the importance of living well and aging gracefully. Their advocacy has encouraged people to look beyond external appearances and consider what’s happening inside the body.
Understanding NAD+ and Its Role
As we age, our NAD+ levels naturally decline. This decline has led to the idea that replenishing NAD+ through supplements could help maintain mobility and reduce the risk of age-related diseases. However, while the science behind NAD+ is promising, much of the evidence still comes from animal studies or small human trials.
Dr Suzanne Wylie, a GP and medical adviser for IQdoctor, explains that while NAD+ is essential for life and its declining levels are linked to aging and disease, claims about dramatic life extension or powerful anti-aging effects in humans are not yet supported by robust clinical data. She notes that most users report subtle improvements in energy levels, mental clarity, or exercise tolerance over time, but these results are gradual and long-term.
Searches for NAD+ supplements have increased significantly, with a more than 200% rise in 2025. This surge has led many to wonder which form of NAD+ is best suited for their needs.
Different Forms of NAD+ and Their Efficacy
There are various ways to take NAD+, each with its own set of benefits and drawbacks. Oral supplements such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) are often considered the safest options, as they have the best safety data and can effectively raise NAD+ levels in the body.
In contrast, intravenous (IV) NAD+ is frequently marketed as being more powerful, despite limited evidence suggesting it leads to better or more durable outcomes. IV treatments are also more expensive and carry higher medical risks.
Topical or skincare products containing NAD+ may improve the appearance of the skin, but they are unlikely to have significant effects on whole-body aging or cellular NAD+ levels. This means that while NAD+ in skincare might be popular at the surface level, it may not lead to major skin barrier repair or cell turnover underneath.
Common Misconceptions About NAD+
One of the biggest misconceptions surrounding NAD+ is the belief that it can reverse aging or act as a shortcut to longevity. Another common myth is that higher doses automatically lead to greater benefits or that intravenous treatments are inherently superior. However, none of these claims have been convincingly proven in well-designed human studies.
Despite these misconceptions, NAD+ should not be overlooked. New research is continually emerging, and Dr Wylie suggests that we may see more developments in this area in the future.
“While it is unlikely to disappear completely given the real biology behind it, at present it should be viewed as an interesting and evolving area rather than a medical essential,” she says. “It’s certainly not a replacement for the fundamentals of good health that we know make the biggest difference over the long term.”
Conclusion
As the wellness landscape continues to evolve, NAD+ remains a topic of interest for those seeking to enhance their health and longevity. While the science is still developing, the potential of NAD+ is worth exploring. However, it’s important to approach it with realistic expectations and a balanced perspective. Always consult with a healthcare professional before starting any new supplement regimen.
