How It Works
How It Works
Magnesium L-Threonate was specifically engineered to cross the blood-brain barrier — something regular magnesium forms can't do effectively. Once in the brain, it supports the synaptic connections that are crucial for memory formation and cognitive function. This targeted delivery makes it fundamentally different from other magnesium supplements.
Who It's For
Adults concerned about memory and cognitive performance, especially those over 40. Students and professionals who rely on mental sharpness. Anyone looking for brain-specific magnesium benefits rather than general muscle or sleep support.
Who It's Not For
Not ideal if you're primarily seeking magnesium for muscle cramps, sleep, or general relaxation — other forms work better for those needs.
About This Product
Natural Factors Magnesium L-Threonate is made with Magtein, a branded magnesium L-threonate. One vegetarian capsule holds 667 mg of Magtein, supplying 48 mg of elemental magnesium. Helps to support cognitive function in the elderly with mild cognitive impairment.
What is magnesium L-threonate?
Magnesium L-threonate is a compound in which magnesium is bound to L-threonic acid, a substance related to vitamin C. Like every magnesium compound, only part of its weight is the mineral itself. That is why 667 mg of Magtein works out to 48 mg of magnesium, and three capsules (2000 mg of Magtein) give 144 mg.

- 90 vegetarian capsules
