What is Magtein®?

Magtein® is the registered trade name of magnesium L-threonate, a magnesium salt of L-threonic acid (a compound derived from vitamin C). In the EU, it is authorised as a novel food in food supplements for adults, excluding pregnant and breastfeeding women.

Each serving of 3 capsules provides 2000 mg of magnesium L-threonate, equivalent to 144 mg of magnesium, i.e. 38% of the Nutrient Reference Value (375 mg).

Take 3 capsules per day in divided doses: 1 capsule in the morning and 2 capsules about 2 hours before bedtime. The 90-capsule pack lasts 30 days.

Magnesium contributes to a reduction of tiredness and fatigue, to electrolyte balance, to normal energy-yielding metabolism, to normal functioning of the nervous system, to normal muscle function, to normal psychological function and to the maintenance of normal bones and teeth.
