The Science Behind NAD+: Why More People (and Celebrities) Are Turning to Cellular Health
In the quest for better health and a longer, more vibrant life, one molecule has taken center stage: NAD+ (nicotinamide adenine dinucleotide).
Once a term reserved for biochemistry textbooks, NAD+ is now generating buzz in wellness clinics, scientific journals, and even Hollywood circles.
At Defy Medical, we’ve been offering NAD+ therapy for years as part of our integrative approach to optimizing health.
But why is NAD+ being hailed as the future of longevity, and why are so many celebrities and health enthusiasts investing in it?
Let’s dive into the science of NAD+, the critical role it plays in your body, and how some of the world’s most recognizable names are embracing it as part of their personal wellness strategy.

What is NAD+?
NAD+ is a coenzyme found in every living cell. It’s essential for basic biological processes, including:
- Energy production: NAD+ helps convert the food you eat into usable energy through cellular respiration.
- DNA repair: It assists in maintaining the integrity of your DNA, reducing the cellular damage that contributes to aging.
- Cell signaling: NAD+ regulates key communication pathways within and between cells, promoting overall health.
- Enzyme activation: It plays a critical role in activating enzymes like sirtuins, which are involved in aging and inflammation control.
In short, without NAD+, your body cannot function properly, and maintaining healthy NAD+ levels is crucial to long-term vitality.
How NAD+ Declines with Age
Unfortunately, NAD+ levels naturally decline as we age — sometimes by as much as 50% by middle age. This decline is associated with:
- Fatigue and reduced energy
- Cognitive decline
- Slower recovery from injury or illness
- Increased risk for chronic diseases
Modern stressors like poor diet, lack of sleep, and environmental toxins can accelerate NAD+ depletion even further.
At Defy Medical, we focus on helping patients replenish NAD+ levels through targeted therapies designed to support energy, mental clarity, and overall well-being.
The Science Behind NAD+ Therapy
At Defy Medical, NAD+ therapy typically involves injectable protocols that deliver NAD+ directly into the bloodstream for maximum absorption. This approach bypasses digestion and allows higher concentrations to reach your cells quickly and effectively.
Defy Medical offers access to NAD+ topical cream and NAD+ nasal spray for patients who want to avoid injections.
Clinical benefits reported by patients and supported by early research include:
- Increased energy and stamina
- Improved cognitive performance (focus, memory, mental clarity)
- Enhanced mood and stress resilience
- Better sleep quality
- Support for healthy metabolism
- Assistance in addiction recovery programs
We approach NAD+ therapy using personalized protocols, often combining it with vitamin therapies, hormone optimization, and integrative wellness strategies for maximum benefit.
It’s important to note that NAD+ therapy is not a magic bullet, but for many, it serves as a powerful tool to optimize cellular health and help support a longer, healthier life.
Celebrities Are Betting on NAD+ for Longevity
While Defy Medical focuses on the science, it’s impossible to ignore the surge of celebrity interest in NAD+. High-profile names are tapping into this therapy to stay sharp, energized, and seemingly ageless.
Joe Rogan, known for his emphasis on health optimization, has spoken openly about using NAD+ infusions to support his intense podcasting, comedy, and fitness schedule.
Hailey Bieber has been linked to NAD+ drips as part of her wellness and beauty routines, focusing on maintaining skin vitality and youthful energy.
Kendall Jenner and Kourtney Kardashian have both reportedly tried NAD+ IVs, tying into the growing trend of biohacking for beauty and longevity.
Meanwhile, Ben Greenfield, a well-known health and fitness expert, calls NAD+ therapy a “game-changer” for brain health and endurance.
Jennifer Aniston has spoken publicly about her enthusiasm for NAD+ therapy, calling it “the future” in an interview with The Wall Street Journal. She highlights NAD+ treatments as a key part of her wellness strategy for maintaining energy and healthy aging.
Science should always guide your health choices, not celebrity endorsements. However, it’s interesting to see how many public figures are turning to NAD+ therapies as part of a larger trend toward preventative health and living longer, healthier lives.
At Defy Medical, we focus on the science-backed benefits of NAD+ therapy, offering personalized programs that prioritize real, sustainable results over fads or trends.
