About this ingredient
Ingredients
Magtein® is the patented, trademarked name for magnesium L-threonate, a specialized form of magnesium developed for brain-focused nutritional formulations. It combines magnesium with L-threonic acid, a compound derived from vitamin C metabolism. The exact elemental magnesium amount depends on the finished product and formulation.
Magtein® is a branded form of magnesium L-threonate used in nutritional supplements focused on magnesium and brain health. It is a specific branded ingredient rather than a generic name for all magnesium L-threonate products.
Magnesium is an essential mineral involved in more than 300 enzyme systems and contributes to normal nerve and muscle function, energy metabolism, electrolyte balance, bone structure, and normal heart rhythm.
Magtein® has been studied in relation to cognitive function, memory, attention, mood, and sleep quality. The manufacturer's information describes it as a brain-bioavailable form of magnesium, while research continues to evaluate the effects of magnesium L-threonate in humans. These findings should not be interpreted as evidence that Magtein® treats or prevents a medical condition.
Magtein® products may be available as capsules, gummies, or other nutritional formulations. The amount of magnesium L-threonate and elemental magnesium can vary by finished product, so check the product label for serving size, magnesium content, additional ingredients, and directions.
