Adults, as a dietary supplement, take three (3) capsules daily. One (1) mid-day and two (2) at night, two (2) hours before bed.

With each three-capsule serving, you receive 2,000 mg of Magtein^® Magnesium L-Threonate, which provides 145 mg of elemental magnesium.

While the amount of elemental magnesium may be lower than some other products on the market, our product is formulated for optimal brain absorption. Because it utilizes a more efficient delivery system, your body receives greater benefit from less magnesium.*

Unlike other forms of magnesium, which can cause gastrointestinal discomfort and loose stools, Magnesium L-Threonate does not act as a laxative and can actually help reduce gastrointestinal discomfort.*

This product was not formulated specifically for pregnant or nursing women. We always recommend consulting with your health care provider before taking a new dietary supplement.
