Comparing Magnesium L-Threonate and Magnesium Glycinate for Mental Health
Comparing Magnesium L-Threonate and Magnesium Glycinate for Mental Health
Living with conditions such as anxiety, insomnia, ADHD, or cognitive decline can be challenging. At Philadelphia Integrative Psychiatry, Dr. Danish and his team are committed to offering evidence-based, integrative care tailored to each patient’s needs. Magnesium supplementation is one such approach that has shown promise in addressing various mental health concerns. Dr. Danish prefers Magnesium L-Threonate and Magnesium Glycinate over other forms like magnesium oxide, chloride, or hydroxide, which are less effective due to poor absorption and higher rates of side effects such as diarrhea. In this blog, we’ll explore the differences between these two superior forms of magnesium and how they may benefit specific conditions.
Less Desirable Magnesium Forms
Before diving into the benefits of Magnesium L-Threonate and Glycinate, it’s important to understand why other forms are less ideal:
Magnesium Oxide: Poorly absorbed and often causes diarrhea, making it unsuitable for most therapeutic uses[1][9].
Magnesium Chloride: Better absorption but often unstable in tablet form; usually taken as a liquid[2][14].
Magnesium Hydroxide (Milk of Magnesia): Primarily used as a laxative due to its strong gastrointestinal effects, not suitable for mental health applications[3][17].
Efficacy of Magnesium L-Threonate vs. Magnesium Glycinate
Magnesium L-Threonate
This form is specifically designed to cross the blood-brain barrier, making it highly effective for cognitive and neurological health:
Cognition & ADHD: Increases brain magnesium levels, enhancing memory, learning, and focus. Studies suggest it supports neuroplasticity and executive functioning[5][11][35].
Dementia Prevention: Protects against cognitive decline by preserving brain volume and reducing white matter lesions[4][28].
Anxiety & Stress: Modulates neurotransmitters like GABA and glutamate, reducing stress while promoting mental clarity[5][55].
Sleep Support: Improves deep sleep stages (REM) by calming the brain’s excitatory pathways[11][58].
Magnesium Glycinate
This form combines magnesium with glycine, an amino acid with calming properties:
Anxiety & Insomnia: Promotes relaxation by supporting GABA activity and regulating melatonin production. Ideal for individuals with sleep disturbances or high stress[6][33].
Tic Disorders: Stabilizes nerve cells and reduces excitability when paired with vitamin B6, but is usually given at higher doses than for the other conditions it is used for [7][44].
General Mental Health: Useful for alleviating muscle tension and improving mood through serotonin production[6][33].
Recommended Dosing and Timing
Magnesium L-Threonate
Typical dosage: 1–2 grams daily (equivalent to 144–200 mg elemental magnesium), divided into morning and evening doses.
Onset: Cognitive benefits may appear within 4–6 weeks; sleep improvements within 2–4 weeks.
Best taken with food to minimize gastrointestinal discomfort[5][35].
Magnesium Glycinate
Typical dosage: 300–400 mg daily for adults; lower doses (50–200 mg) for children based on age.
Onset: Anxiety relief and improved sleep may be noticeable within 1–2 weeks.
Best taken in the evening to maximize its calming effects before bedtime[6][30].
Potential Side Effects
Both forms are well-tolerated but may cause mild side effects at higher doses:
Magnesium L-Threonate: Headaches or gastrointestinal upset if taken in excessive amounts[5][35].
Magnesium Glycinate: Nausea or diarrhea at high doses, though it is gentler on the stomach compared to other forms like oxide or citrate[6][33].
Interactions with Other Medications
Both supplements can interact with certain medications:
May reduce absorption of antibiotics (e.g., tetracyclines) or bisphosphonates used for osteoporosis.
Can interact with thyroid medications or anticoagulants like warfarin. Always consult a healthcare provider before starting supplementation if you are taking other medications[9][15].
How to Choose Between Them
The choice between Magnesium L-Threonate and Magnesium Glycinate depends on individual needs:
Condition
Best Option
Reason
Anxiety
Magnesium Glycinate
Calming effects via GABA modulation; promotes relaxation.
Insomnia
Magnesium Glycinate
Superior for improving sleep quality through muscle relaxation.
ADHD/Cognition
Magnesium L-Threonate
Enhances focus, memory, and learning by increasing brain magnesium levels.
Dementia Prevention
Magnesium L-Threonate
Strong evidence for neuroprotection and cognitive preservation.
Tic Disorders
Either form
Both stabilize nerve cells; glycinate is preferred when paired with vitamin B6.
In cases where multiple concerns overlap (e.g., ADHD with anxiety), combining both forms under medical supervision may provide synergistic benefits.
