Frequently Asked Questions
Q1: Is L-threonate Magnesium powder the same as Magtein®?
A: Magtein® is the patented, trademarked brand name for the specific magnesium L-threonate compound developed by AIDP/ThreoTech. While generic L-threonate Magnesium powder exists chemically, Magtein is the most clinically studied version, holding the majority of the intellectual property for brain health claims.
Q2: What is the recommended daily dosage for clinical efficacy?
A: Clinical trials demonstrating cognitive improvement typically use a dosage of 2 grams per day (providing approximately 144-168 mg of elemental magnesium). This is often split into two doses (morning and evening) to maintain serum levels.
Q3: Does it help with sleep or just cognition?
A: While the primary mechanism is cognitive, studies show mixed results. The 2026 clinical trial noted significant improvements in self-reported sleep impairment (feeling rested) and a reduction in resting heart rate during sleep, even if it didn't drastically change sleep architecture. It is excellent for stress reduction which leads to better sleep quality.
Q4: Is it safe for long-term use?
A: Yes. It has received FDA GRAS status and positive safety reviews from EFSA in Europe. It is generally recognized as safe for adults, though pregnant or lactating women are currently excluded from the EU usage conditions
