Dr. Mercola Magnesium Advanced, 90 Capsules

Dr. Mercola Magnesium Advanced is a dietary supplement formulated to support brain health and overall bodily functions with a focus on absorption and minimal gastrointestinal discomfort. It features Magtein, a patented form of Magnesium L-Threonate, which is noted in manufacturer-provided research for its ability to cross the blood-brain barrier and raise brain magnesium levels. Each three-capsule serving delivers 2,000 mg of this compound, providing 145 mg of elemental magnesium, a dosage aligned with clinical studies on cognitive support.

This product is distinguished by its use of Magtein, a trademarked ingredient backed by peer-reviewed studies on absorption and brain penetration. The manufacturer emphasizes that this form is designed to reduce laxative effects common with other magnesium types, and it carries a 'green' label in their Stoplight System to indicate gentleness on the gut. Available in a 90-capsule bottle, it is produced without GMOs or gluten, following Dr. Mercola's quality standards established over decades.
