This is a meaningful distinction: virtually all other magnesium supplements increase serum magnesium and may improve general tissue magnesium status, but they have minimal impact on brain magnesium — which is regulated independently and is critical for synaptic plasticity, the cellular mechanism underlying memory formation, learning, and cognitive flexibility.\u003c\/p\u003e\u003cp\u003eEach 3-capsule serving provides 2,000mg of Magtein magnesium L-threonate, delivering approximately 144mg of elemental magnesium per serving. Animal studies demonstrated that Magtein supplementation increased brain magnesium levels by over 15% compared to other forms and improved both short-term and long-term memory performance. Human clinical trials have shown improvements in cognitive composite scores, with benefits appearing particularly meaningful in the context of age-associated cognitive decline. The morning\/evening split dosing protocol (2 capsules AM, 1 capsule PM) is specifically designed to optimize brain magnesium levels throughout the day and support sleep quality at night.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagtein® magnesium L-threonate 2,000mg per serving (3 capsules)\u003c\/strong\u003e — MIT-patented form\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eOnly magnesium form proven to significantly raise brain magnesium levels\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSupports memory, learning, synaptic plasticity, and cognitive performance\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSplit dosing protocol\u003c\/strong\u003e — 2 caps AM, 1 cap PM for optimal brain magnesium throughout the day\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e270 capsules\u003c\/strong\u003e — 90-day supply; non-GMO, gluten-free\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTake 2 capsules in the morning and 1 capsule in the evening, or as directed by your healthcare provider.\u003c\/p\u003e","brand":"Dr. Mercola","offers":[{"title":"Default Title","offer_id":51252271153454,"sku":"000000000300086723","price":108.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/3297\/1822\/files\/515x515-0009018-magnesium-l-threonate-270-capsules.png?v=1779658445","url":"https:\/\/www.drmattgianforte.com\/products\/magnesium-l-threonate-270-capsules","provider":"Dr Matt Gianforte","version":"1.0","type":"link"}
