Frequently Asked Questions

What is Magnesium L-Threonate and how is it different from other magnesium supplements?

Magnesium L-Threonate (Magtein®) is the only form of magnesium clinically shown to cross the blood-brain barrier. Developed by MIT researchers, it raises magnesium levels directly in the brain, supporting cognitive function, memory, and mental clarity — something other forms like magnesium oxide or citrate cannot do effectively.

How many servings are in the 90-capsule bottle?

The 90-capsule bottle provides 30 servings, with 3 capsules per serving delivering 2,000 mg of Magtein® Magnesium L-Threonate. This is the starter or travel-friendly size; the 270-capsule bottle provides 90 servings.

Will this cause digestive issues or act as a laxative?

No. Unlike magnesium oxide or citrate, magnesium L-threonate does not act as a laxative and is gentle on the digestive system. It is absorbed at the cellular level without causing GI discomfort or loose stools.

When is the best time to take this supplement?

The recommended dosing is 1g (approximately 1.5 capsules) after lunch and 1g at bedtime for optimal results. Taking a portion at bedtime may also support relaxation and sleep quality.

Is this product free from common allergens?

Yes. Dr. Mercola's Magnesium Advanced is GMO-free, gluten-free, and soy-free.

What health benefits does Magnesium L-Threonate support?

Magnesium L-Threonate supports cognitive function and memory, relaxation and sleep quality, healthy brain aging, and overall nervous system health. Its ability to cross the blood-brain barrier makes it uniquely effective for brain-focused magnesium support compared to other forms.
