What is Magnesium good for?

Magnesium is an essential mineral required for more than 300 enzymatic reactions in the body. Magnesium benefits include support for essential muscle, heart and nerve function and for converting food into cellular energy. Magnesium also helps relax the body. However, over half of American adults (54%) have daily Magnesium intake levels below recommendations.[1] For those who do not consume enough from their diet, Magnesium supplements help provide this essential nutrient to help close the nutrient gap.†

What is Magnesium L-Threonate?

Magnesium L-threonate, or Magnesium threonate, is a form of the mineral magnesium. Other forms found in magnesium supplements include magnesium citrate, magnesium glycinate, magnesium malate, and magnesium oxide. Magtein® is a proprietary form of Magnesium L-Threonate. Magtein® Magnesium L-Threonate has been clinically studied to support healthy cognitive function, including short-term memory, in older adults in 12 weeks‡.†

Does Magnesium L-Threonate cross the blood-brain barrier to raise Magnesium levels in the brain?

Maybe. The blood-brain barrier is a network of blood vessels and tissue that moderates which substances can pass through to the brain, and we understand the way this form of magnesium works in humans based on studies that have been performed on animals. Because the Magnesium L-Threonate form was studied in a series of pre-clinical trials that involved testing on animals (not humans), it has not yet been proven that this form of Magnesium crosses the blood-brain barrier in the human brain.

Can I give this Magnesium supplement to my child?

No, these Magnesium L-Threonate capsules are designed for adults. Check out our Kids First® Gummies for some kid-friendly supplements.

How do I take these Magnesium capsules?

Adults, take 3 capsules daily with water and a meal. Consult with a healthcare practitioner for use beyond 3 months.†

When does this product expire?

Good question. Please refer to the expiration date on the bottle.
