Magtein® is a highly regarded branded form of magnesium L-threonate, widely recognised for its superior bioavailability compared with standard magnesium forms. Each daily serving of 3 capsules delivers 2000 mg of Magtein®, providing 144 mg of elemental magnesium (38% NRV). What sets this form apart is its ability to cross the blood-brain barrier, making it a particularly appealing option for those prioritising cognitive support alongside general magnesium intake.
Magnesium contributes to normal psychological function, the reduction of tiredness and fatigue, normal muscle function, and the maintenance of electrolyte balance — making it a versatile mineral for both mentally demanding periods and physical training. Magtein® is especially popular with students, professionals, and athletes who want targeted nutritional support from a well-researched ingredient.
Each capsule uses a vegetable pullulan shell with no fillers or anti-caking agents — just the active ingredient and its casing. The formula is completely free from animal-derived ingredients, making it suitable for vegans and vegetarians. Ninety capsules per pack ensures a generous supply at the full recommended daily dose.
