Dr. Haver's Top Recommendation: Magnesium L-Threonate
For those wondering what type of magnesium does Dr. Mary Claire Haver recommend, her answer is unequivocally Magnesium L-Threonate. The reason she prioritizes this specific form is its unique ability to cross the blood-brain barrier, allowing it to directly benefit brain function. Developed by researchers at MIT, Magnesium L-Threonate has shown promise in studies for supporting overall brain health, including learning, memory, and cognitive function. Dr. Haver personally takes Life Extension Neuro Mag, a supplement formulated with Magnesium L-Threonate, to aid in sleep and cognitive health. This focus on a highly bioavailable form that targets the brain sets her recommendation apart from generic magnesium supplements that may be less effectively absorbed.
Why Magnesium L-Threonate is Key for Menopause
During perimenopause and menopause, many women experience a range of symptoms that affect mental clarity and sleep quality. These include brain fog, anxiety, and insomnia. Dr. Haver's recommendation for Magnesium L-Threonate is a strategic one, aimed at addressing these specific concerns. As she has noted, it is especially helpful for improving sleep and managing night sweats, common issues in menopausal women. By enhancing nerve signal transmission and protecting brain cells, this form of magnesium can make a significant difference in a woman's quality of life. It is a targeted approach to supplementation, focusing on a form with specific, scientifically-supported benefits rather than just increasing general magnesium levels.
Understanding the Different Forms of Magnesium
While Magnesium L-Threonate is Dr. Haver's go-to for brain and sleep support, it's helpful to understand how it compares to other common forms. Many magnesium supplements are available, each with a different absorption rate and purpose. For example, Magnesium Glycinate is also a well-absorbed form known for its calming effects, making it a popular choice for anxiety and sleep. On the other hand, Magnesium Citrate is often used to relieve constipation due to its laxative effect. Being aware of these differences is crucial for choosing the right supplement for your specific health needs.
A Comparison of Common Magnesium Forms
| Magnesium Form | Primary Benefit | Absorption Rate | Key Use Case |
|---|---|---|---|
| L-Threonate | Brain health, cognitive function, sleep | Very good, crosses blood-brain barrier | Cognitive support, insomnia, brain fog |
| Glycinate | Relaxation, anxiety, sleep | Very good | Calming effects, stress reduction, anxiety relief |
| Citrate | Constipation relief | Good | Constipation, effectively raises magnesium levels |
| Malate | Energy, muscle pain | Good | Chronic pain, fatigue |
| Oxide | Laxative effect | Poor | Generally not recommended for increasing levels |
Dietary Sources and Daily Requirements
Even with supplementation, incorporating magnesium-rich foods into your diet is vital. Dr. Haver emphasizes the importance of getting nutrients from whole foods whenever possible. The recommended daily allowance for adult women is around 320 mg/day, though some research suggests a higher intake might be beneficial for brain health as we age. Some excellent dietary sources of magnesium include:
- Pumpkin Seeds: A small serving can provide a significant amount.
- Spinach: This leafy green is packed with magnesium.
- Almonds: A great snack option for boosting magnesium intake.
- Avocados: Loaded with healthy fats and magnesium.
- Fatty fish: Including salmon and mackerel.
Dr. Haver points out that while some plant-based foods like spinach and certain seeds are rich in magnesium, factors like oxalates and phytic acid can inhibit absorption, so bioavailability is key. This further underscores why supplementation with a highly absorbable form like L-Threonate can be so important.
Supplementing Wisely
Dr. Haver's approach to supplementation is strategic, not speculative. She advises patients to first assess their nutritional needs, possibly using a tracker, to see where their diet falls short before adding supplements. Always consult with a healthcare professional before beginning any new supplement regimen, especially during menopause when hormonal shifts can complicate matters. A doctor can provide personalized advice based on your specific health profile and symptoms.

Conclusion
When it comes to addressing brain fog, sleep issues, and other cognitive symptoms related to menopause, Dr. Mary Claire Haver recommends a specific and targeted approach. Her preference for Magnesium L-Threonate is based on its unique ability to cross the blood-brain barrier, providing direct support for the brain. While a nutrient-dense, anti-inflammatory diet is always the foundation of good health, a high-quality Magnesium L-Threonate supplement can be a powerful tool for filling nutritional gaps and mitigating menopausal symptoms. By understanding the different types of magnesium and consulting with a healthcare provider, women can make an informed decision to support their brain and body during this life stage.
