Peter Attia on NAD+ Boosters: A Deep Dive

Peter Attia, MD, a physician specializing in longevity, has significantly influenced the conversation around preventative health and extending lifespan. A key component of his approach, and a frequent topic of discussion, revolves around NAD+ (Nicotinamide Adenine Dinucleotide) and strategies to boost its levels. This article delves into Attia’s perspective, the science behind NAD+, and the current state of NAD+ boosters.

What is NAD+ and Why is it Important?

NAD+ is a crucial coenzyme found in every cell in your body. It’s involved in hundreds of metabolic processes, including energy production, DNA repair, and cellular signaling. Levels naturally decline with age – a decline strongly correlated with age-related diseases like Alzheimer’s, heart disease, and type 2 diabetes. Attia emphasizes that this decline isn’t merely a correlation; it’s increasingly viewed as a potential driver of aging itself.

Attia’s Approach to NAD+ Enhancement

Attia doesn’t advocate for simply taking NAD+ directly. He believes the molecule has poor bioavailability – meaning the body doesn’t absorb it well when ingested. Instead, he focuses on precursors to NAD+, substances the body can convert into NAD+. His preferred methods, as of late 2023/early 2024, primarily involve:

• Nicotinamide Riboside (NR): Attia initially favored NR, citing its relatively good safety profile and ability to raise NAD+ levels.
• Nicotinamide Mononucleotide (NMN): More recently, Attia has shifted towards NMN, believing it may be more effective at increasing NAD+ levels, despite some lingering questions about its long-term effects.
• Trimethylglycine (TMG): Often taken with NMN, TMG supports the methylation process necessary for NMN conversion to NAD+.

He stresses the importance of cycling these precursors – using them for periods, then taking breaks – to potentially avoid downregulation of NAD+ salvage pathways. He also highlights the need for personalized dosing, guided by blood testing.

The Science Behind the Boosters

Research on NAD+ precursors is ongoing. Studies (primarily in mice and some early human trials) suggest potential benefits including:

• Improved insulin sensitivity
• Enhanced mitochondrial function
• Increased DNA repair capacity
• Neuroprotective effects

However, it’s crucial to note that much of the research is preliminary. Long-term effects in humans are still largely unknown. The optimal dosage, duration of use, and potential side effects require further investigation.

Controversies and Considerations

The NAD+ booster space isn’t without controversy. Concerns include:

• Purity and Quality Control: The supplement industry is often poorly regulated. Ensuring the quality and purity of NAD+ precursors is vital.
• Potential Side Effects: While generally considered safe, some individuals may experience side effects like nausea, flushing, or digestive upset.
• Long-Term Effects: The long-term consequences of chronically elevating NAD+ levels are unknown.
• Cost: NAD+ precursors can be expensive.

Attia’s Caveats & Future Directions

Attia consistently emphasizes that NAD+ boosting is just one piece of the longevity puzzle. He advocates for a holistic approach encompassing diet, exercise, sleep, and stress management. He also acknowledges that the science is evolving and his recommendations may change as new data emerges. He actively supports research aimed at better understanding NAD+ metabolism and its role in aging.
