Approximately 54% of Americans do not consume enough magnesium from their diet alone, making supplementation a common practice. In his comprehensive approach to longevity, Dr. Peter Attia strategically uses multiple brands and forms of magnesium to target various health objectives, rather than relying on a single brand. He tailors his supplement choices based on desired effects, ranging from cognitive function to gut health.

Quick Summary

Dr. Peter Attia incorporates several forms of magnesium, including SlowMag (magnesium chloride) for general absorption and muscle health, Magtein (magnesium L-threonate) for cognitive function, and magnesium oxide for gastrointestinal support. His strategy involves tailoring the type of magnesium to specific health goals.

Key Points

  • Multiple Forms: Peter Attia uses several types of magnesium, not just one brand.

  • SlowMag: He takes SlowMag (magnesium chloride) for general absorption and muscle health.

  • Magtein: Magtein (magnesium L-threonate) is used for cognitive benefits and brain function.

  • Magnesium Oxide: This form is utilized for gastrointestinal support due to its lower absorption.

  • Personalized Approach: Attia's supplementation is highly tailored to his individual health markers and goals.

  • Goal-Oriented: Different forms of magnesium are chosen based on the specific health outcome desired.

Peter Attia's Multi-Faceted Magnesium Strategy

Dr. Peter Attia's approach to supplementation is highly personalized and evidence-based, focusing on maximizing healthspan and longevity. When it comes to magnesium, he does not rely on just one brand or form, but rather employs a strategic combination of several, each chosen for its specific properties and benefits. This section details the specific brands and types of magnesium he uses and the rationale behind each choice.

SlowMag (Magnesium Chloride) for Systemic Absorption

For foundational, well-absorbed systemic magnesium, Dr. Attia favors the brand SlowMag. SlowMag is a slow-releasing magnesium chloride supplement that is formulated with an enteric coating. This coating allows it to bypass the stomach and break down in the small intestine, which can help minimize the gastrointestinal upset that some people experience with other forms of magnesium. He uses this form to support general cardiovascular health and help with muscle cramping. Magnesium chloride is a highly bioavailable form, making it effective for boosting overall magnesium levels in the body.

Magtein (Magnesium L-Threonate) for Cognitive Health

For brain health and cognitive support, Dr. Attia specifically takes magnesium L-threonate from the brand Magtein. The unique benefit of this patented form is its ability to effectively cross the blood-brain barrier. This means it can increase magnesium concentrations in the brain more effectively than other forms, which is important for cognitive functions like learning and memory. He typically takes this form before sleep to aid with his nightly recovery and cognitive function. He has emphasized the importance of ensuring a product contains the patented Magtein ingredient when seeking out magnesium L-threonate.

Magnesium Oxide for Gastrointestinal Regulation

Dr. Attia also uses magnesium oxide, a form with significantly lower bioavailability, for a different purpose: gastrointestinal support. Because it is not well-absorbed, it stays in the digestive tract and can help with regulating bowel function and mitigating issues like constipation. This demonstrates his meticulous approach to supplementation, where a form of a nutrient that is poorly absorbed for one purpose can be highly effective for another.

Comparison of Magnesium Forms Taken by Peter Attia

Feature SlowMag (Magnesium Chloride) Magtein (Magnesium L-Threonate) Magnesium Oxide
Primary Use General absorption, cardiovascular health, muscle cramps Cognitive function, memory, sleep Gastrointestinal support, constipation relief
Bioavailability High High (specifically for the brain) Low
Brand SlowMag Patented Magtein Standard magnesium oxide
Mechanism Slow-release, enteric coating Crosses blood-brain barrier Acts as an osmotic laxative
Benefit Sustained magnesium levels, less GI upset Supports brain function and sleep Regulates bowel movements effectively

The Importance of Individualized Nutrition

Dr. Attia's strategy highlights a crucial point in nutrition: not all supplements are created equal, and not every supplement is right for every person. His regimen is highly tailored to his specific biomarkers and health goals, based on regular bloodwork and clinical insight. For the average person, it is not recommended to blindly copy a complex supplement stack. Instead, the takeaway is to understand the different forms of a nutrient and how they might best serve individual health needs.

Conclusion: Beyond the Brand Name

Rather than endorsing a single brand, Peter Attia's dietary practice involves selecting specific forms of magnesium—SlowMag for general health, Magtein for the brain, and magnesium oxide for gut function—to achieve distinct health outcomes. This personalized, evidence-based approach is a hallmark of his philosophy on proactive health management. For those interested in supplementing, this means understanding the nuances of different magnesium types and consulting with a healthcare professional to determine the most suitable option for their own unique needs.

Key Factors for Choosing Your Magnesium Supplement

  • Analyze your primary health goals: Decide if you are targeting brain function, sleep, muscle recovery, or digestion before choosing a specific form.
  • Consider bioavailability: Opt for highly absorbable forms like magnesium glycinate or citrate for better overall magnesium status, while reserving less absorbed forms like oxide for specific uses like constipation.
  • Check for third-party testing: Look for certifications from reputable organizations like NSF or USP to ensure product quality, purity, and potency.
  • Consult with a healthcare provider: Always speak with a doctor before starting any new supplement, especially with existing conditions or other medications.
  • Factor in potential side effects: Be aware that certain forms like magnesium citrate or oxide are more likely to cause gastrointestinal issues.
  • Assess your overall diet first: Prioritize magnesium-rich foods such as leafy greens, nuts, seeds, and whole grains, and use supplements to fill any dietary gaps.
