Decoding the Wellness Trend: Which NAD Do the Kardashians Use?

October 4, 2025 •

4 min read

In a 2022 episode of The Kardashians, Hailey Bieber declared to Kendall Jenner, “I’m going to NAD for the rest of my life, and I’m never going to age,” as they received NAD+ IV therapy. This public endorsement, among others by the family and their associates, has spurred significant interest in the anti-aging molecule and the specific forms they use. The reality is that the family uses different types and methods to boost their NAD+ levels.

Quick Summary

Several members of the Kardashian family and their inner circle, including Kendall Jenner and Kim Kardashian, use NAD+ boosters for energy and longevity. The methods range from intravenous (IV) infusions, famously featured on their show, to oral supplements and injections of precursors like NMN. Their endorsements have amplified the popularity of these cellular health treatments.

Key Points

IV Therapy Endorsed by Kendall and Hailey: Kendall Jenner and her friend Hailey Bieber have publicly received NAD+ IV drips on their reality show, citing benefits like energy and anti-aging.
Kim Kardashian's Use of NMN: Reports indicate Kim Kardashian uses NAD+ precursors like NMN, potentially via injection, as part of her longevity and wellness routine.
Kourtney Kardashian's Supplement Advocacy: While not featuring an NAD+ product in her Lemme line, Kourtney Kardashian has publicly praised NAD+ supplements for their anti-aging benefits.
Oral Supplements Are an Alternative: While IV drips are known for high bioavailability, oral supplements containing NAD+ precursors like NR (found in Tru Niagen) and NMN are a more accessible option.
High Cost of IV Therapy: Celebrity-endorsed NAD+ IV infusions can be expensive, with some treatments costing upwards of $1,000, while oral supplements are significantly cheaper for daily use.
Biohacking Drives the Trend: The Kardashians' use of NAD+ is part of a broader celebrity 'biohacking' trend that seeks to optimize health and wellness through advanced treatments.
Consult a Professional: Experts advise consulting with a healthcare professional before starting any NAD+ therapy, as research on long-term effects is still ongoing.

The Kardashian's Approach to NAD+ Boosting

While the Kardashian-Jenner clan is known for setting beauty and wellness trends, their approach to Nicotinamide Adenine Dinucleotide (NAD+) is not uniform. Several prominent members and their close associates have publicly endorsed different methods, from high-end IV infusions to oral supplements. This variation reflects not only individual preferences but also the diverse options available on the market for boosting cellular energy and promoting longevity.

Kendall Jenner and Hailey Bieber: NAD+ IV Drips

The most high-profile and visual example of the family's NAD+ use is the IV infusion. On an episode of their reality series, Kendall Jenner and Hailey Bieber were shown receiving NAD+ intravenously. This method involves administering the coenzyme directly into the bloodstream, bypassing the digestive system for maximum absorption. Known for being the most potent and immediate form of delivery, NAD+ IV therapy is a luxury treatment that can be administered in a clinic or at home.

The Benefits and Considerations of IV Therapy:

Bioavailability: IV delivery provides 100% bioavailability, meaning the body absorbs the highest possible amount.
Speed: Benefits like increased energy and mental clarity can sometimes be felt more quickly than with oral supplements.
Experience: For wellness-conscious individuals like Jenner, the practice is a part of their health routine and is often seen as a social activity.

Kim Kardashian and NMN

In recent reports, Kim Kardashian has been associated with nootropics and longevity supplements, including Nicotinamide Mononucleotide (NMN), a precursor that the body converts into NAD+. While specific brand information is not readily publicized, this suggests a different, and perhaps more frequent, approach to boosting NAD+ levels. Some reports also mention injectable NAD+ as a method used for faster delivery and absorption.

Kourtney Kardashian and Oral Supplements

As the founder of the supplement brand Lemme, Kourtney Kardashian has cemented her place in the wellness industry. While her product line, including gummies for sleep, immunity, and weight management, does not explicitly feature an NAD+ supplement, she has publicly spoken about taking NAD+ supplements and calling the molecule the "genetic key to longevity". This demonstrates her belief in the benefits of oral supplementation for boosting NAD+. This approach is often more accessible and integrated into a daily routine.

Comparison of NAD+ Boosting Methods


Feature	NAD+ IV Therapy	Oral NAD+ Supplements (NR/NMN)
Administration	Intravenous drip, administered by a professional.	Capsules, tablets, or powders, self-administered.
Bioavailability	100% absorption, bypassing the digestive system entirely.	Varied absorption, as the supplement must be broken down in the digestive system.
Cost	High, often several hundred to over a thousand dollars per session.	More affordable and suitable for long-term daily use.
Convenience	Less convenient, requiring an appointment and time commitment.	Very convenient for daily, at-home use.
Celebrity Association	Kendall Jenner, Hailey Bieber.	Kim Kardashian (NMN), Kourtney Kardashian (Supplements).

Understanding the Science of NAD+

NAD+ is a crucial coenzyme found in every cell of the body, playing a central role in energy metabolism, DNA repair, and gene expression. Our NAD+ levels naturally decline with age, which is why boosting these levels has become a popular strategy in the anti-aging and longevity space. By supporting cellular health, some hope to counteract the effects of aging, from cognitive decline to decreased energy.

The most common oral supplements, Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN), are precursors that help the body produce more NAD+. Brands like Tru Niagen, which features NR, are associated with celebrities like Kendall Jenner and Hailey Bieber.

Expert Perspectives and Practical Takeaways

While celebrity endorsements bring attention to NAD+ therapy, it is vital to approach it with a balanced perspective. Medical professionals and researchers acknowledge that while NAD+ levels can be boosted, the long-term effects of many therapies, especially IV infusions, are still under investigation. It is essential to consult a healthcare provider to determine the best approach for individual health goals and to ensure safety. Ultimately, the Kardashian-Jenner family's different choices reflect that there is no one-size-fits-all solution, but a growing interest in leveraging cellular science for health and longevity.

Conclusion

For those wondering which NAD the Kardashians use, the answer is that it varies. Kendall Jenner and Hailey Bieber have famously used IV therapy for a potent, fast-acting boost, while Kim and Kourtney have explored oral supplements or injections, including precursors like NMN. This celebrity-driven trend has highlighted NAD+ as a critical molecule for cellular health, energy, and anti-aging. While their endorsements have boosted the compound's popularity, potential users should research the different delivery methods, consider the cost, and seek medical advice before beginning any new supplement or therapy. The science of longevity is evolving, and the Kardashians' wellness choices offer a high-profile window into this cutting-edge field.
