Buying Guide
Form and Bioavailability
Not all magnesium supplements are created equal. Magnesium L-threonate stands out because it is the only form that can significantly raise magnesium levels in the brain. This is thanks to the threonic acid molecule, which acts as a carrier. Both Double Wood and Sports Research use Magtein, the patented compound developed by MIT researchers. That means you get the same clinically studied ingredient, regardless of which brand you choose. When evaluating any magnesium threonate product, always confirm it contains Magtein to ensure you are getting the real, brain-targeting formula.
Dosage and Serving Size
Magnesium threonate is typically dosed at 2000 mg per serving, which provides a meaningful amount of elemental magnesium. Double Wood offers 120 capsules per bottle, while Sports Research provides 90 capsules. Both recommend taking two capsules daily, so the Double Wood bottle lasts 60 days and the Sports Research bottle lasts 45 days. Consider how often you plan to take the supplement and whether you prefer a longer supply or a smaller commitment. Consistency is key for cognitive benefits, so choose a serving size that fits your routine.
Quality and Purity
Third-party verification is a hallmark of trustworthy supplements. Double Wood emphasizes rigorous third-party analysis for potency and purity. Sports Research also highlights that their product is non-GMO verified and free from gluten and gelatin. Both brands manufacture in the United States in cGMP compliant facilities. When you invest in a magnesium threonate supplement, you want assurance that what is on the label matches what is in the capsule. These two brands deliver that peace of mind.
