The Newest Craze in Celebrity Wellness: NAD+

From Hollywood icons to health gurus and social media influencers, there’s one molecule that’s gaining serious traction in the wellness world: NAD⁺. Praised for its potential anti-ageing benefits and energy-boosting properties, it’s quickly becoming a staple in high-profile health routines — but is it really the key to slowing down the ageing process?

Let’s take a closer look at what NAD⁺ actually is, why it’s trending and whether the hype is supported by science.

What Is NAD+?

First identified in 1906, our understanding of Nicotinamide Adenine Dinucleotide (NAD⁺) has evolved dramatically over the last century. Today, NAD⁺ is recognised as a vital coenzyme found in all living cells, where it plays a key role in multiple biological processes.

At a cellular level, NAD⁺ is involved in:

• Energy metabolism – helping convert food into usable energy (ATP)
• Mitochondrial function – supporting the powerhouses of our cells
• DNA repair – assisting in the maintenance of genetic material
• Cellular ageing – activating sirtuins, a group of proteins linked with longevity

Research suggests that NAD⁺ helps regulate inflammation, maintain metabolic health and may contribute to cellular resilience over time. However, NAD⁺ levels naturally decline as we age, a process thought to be influenced by increased DNA damage and overactivity of NAD⁺-consuming enzymes.

This decline is believed to contribute to some of the more common signs of ageing, including fatigue, slower recovery and reduced cognitive sharpness. As a result, NAD⁺ supplementation has emerged as a potential way to support cellular health from the inside out.

It’s not just a wellness buzzword — the science is there to back it up.

What Are The Celebrities Saying?

NAD⁺ has moved from the lab to the limelight, with many high-profile names incorporating it into their health routines. Celebrities including Hailey and Justin Bieber, Kendall Jenner, Gwyneth Paltrow, Joe Rogan and Jennifer Aniston have all expressed enthusiasm for NAD⁺ therapy.

In an episode of The Kardashians Bieber and Jenner are seen receiving NAD⁺ IV infusions side-by-side. “I’m gonna NAD for the rest of my life and I’m never gonna age,” claims Bieber. Jenner, meanwhile, noted that incorporating NAD⁺ into her post-COVID wellness routine brought comfort and a renewed sense of wellbeing: “Things like this, they comfort me. They help because it just makes me happy.”

Elsewhere, Gwyneth Paltrow has spotlighted NAD+ in wellness content, and Jennifer Aniston has reportedly described NAD+ therapy as “the future” — a sentiment echoed by many in the biohacking and longevity space.

The Bottom Line: Is It Worth The Hype?

The volume of celebrity endorsements in the last few years reflect a growing interest in NAD+ as a potential tool for supporting long-term health. From aiding energy levels to supporting brain function and recovery, there is emerging evidence that boosting NAD⁺ levels could offer meaningful benefits — particularly as part of a broader lifestyle approach to healthy ageing.

Conclusion

NAD+ is certainly taking the industry by storm, not just for its celebrity following, but for the genuine scientific interest behind it. 

So while it might be making headlines for its A-list fans, NAD+ is far more than just another passing trend. Backed by decades of research and growing clinical insight, it’s becoming a mainstay in the future of health optimisation.
