Magtein Magnesium L-Threonate Thorne Cognitive Vitality Three capsules provide 2,000 mg of Magtein magnesium L-threonate, delivering 144 mg of elemental magnesium. The form is the entire point: magnesium L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, which is what lets it raise magnesium levels in the brain specifically rather than only in the body.* The magnesium here is bound to threonic acid, a compound derived from vitamin C. Magtein is patented and clinically studied, and has been shown to support neurological processes involved in memory formation, learning, relaxation, and healthy sleep regulation.* It is also NSF Certified for Sport, which is unusual for a cognitive product.

Reaching neural tissue is a different problem, and it comes down to what the mineral is bound to. 🧠 Magnesium L-Threonate Magnesium regulates neural pathways and supports healthy cognitive function, but getting it into the brain is the constraint. L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, so this form raises magnesium levels in the brain rather than only elsewhere.* The magnesium is bound to threonic acid, derived from vitamin C. 144 mg elemental · Blood-brain barrier 🔬 Magtein A patented and clinically studied form of magnesium L-threonate, shown to support key neurological processes involved in memory formation, learning, relaxation, and healthy sleep regulation.* Magtein is a trademark licensed exclusively by ThreoTech LLC and is protected under a family of global and pending patents. 2,000 mg · Patented form What It Supports Cognition First, Everything Magnesium Does Second 🎯 Cognitive function, focus and learning Cognition 🧠 Short and long-term memory Memory 🙂 Positive mood and emotional well-being Mood ☀️ Mental alertness and daytime energy Alertness 😴 Sleep quality and quantity Sleep ❤️ Heart, vessels, bones and muscles Systemic 🫀 Normal heart rate and rhythm Electrical activity 🩸 Vasodilation and blood flow Circulation Full Spec Sheet Specifications Supplement Facts (Per 3 Capsules) Serving size 3 capsules Servings per container 30 Magtein Magnesium L-Threonate 2,000 mg Magnesium (elemental) 144 mg Formula & Product Details Other ingredients Hypromellose (derived from cellulose) capsule, Microcrystalline Cellulose, Ascorbyl Palmitate Magnesium bound to Threonic acid, derived from vitamin C Ingredient source Magtein, a trademark licensed exclusively by ThreoTech LLC, protected under a family of global and pending patents Unit count 90 capsules Dietary Gluten free, dairy free, soy free Certification NSF Certified for Sport Trusted & Certified Tested Batch By Batch NSF NSF Certified for Sport Every batch tested for compliance with label claims and for the absence of nearly 300 substances banned by many major athletic organizations Questions Frequently Asked Questions How much do I take? + Three capsules daily, or as recommended by your health-care practitioner. Note that the full serving is three capsules rather than one or two, so the 90-capsule bottle is a 30-day supply. Why does the label say 2,000 mg but only 144 mg of magnesium? + Those are two different measurements. 2,000 mg is the amount of the Magtein magnesium L-threonate compound; 144 mg is the elemental magnesium inside it. Elemental magnesium is the figure to use when comparing against other magnesium products, since every form carries a different proportion of it. Why L-threonate rather than another form of magnesium? + Because of where it goes. Magnesium L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, so it raises magnesium levels in the brain rather than only in circulation.* If your reason for taking magnesium is cognition, that is the difference. For sleep and muscle relaxation, glycinate is the usual choice; for digestive regularity, citrate. What is Magtein? + A patented and clinically studied form of magnesium L-threonate, shown to support neurological processes involved in memory formation, learning, relaxation, and healthy sleep regulation.* It is licensed exclusively by ThreoTech LLC and protected under a family of global and pending patents. Can it cause digestive upset? + Thorne's label carries the standard magnesium note: gas, bloating, or diarrhea may occur in some individuals taking magnesium supplements. The amount at which this happens varies by person and it resolves when the amount is reduced. Am I getting enough magnesium generally? + Thorne cites an estimate that around 75% of US adults fall short of the FDA's 420 mg recommended daily intake. Magnesium is involved in more than 600 enzymatic processes affecting cardiac, immune, musculoskeletal, nerve, urinary tract and gastrointestinal function, and low levels can present as muscle cramps, soreness, fatigue, poor sleep, or digestive irregularity. Are there any warnings or interactions? + This product is contraindicated in anyone with a history of hypersensitivity to any of its ingredients. If pregnant, consult your health-care practitioner before using this product. Thorne reports no known adverse interactions or contraindications as of the label's publication date. * These statements have not been evaluated by the Food and Drug Administration.
