ProHealth Magnesium L-Threonate

A three-capsule serving provides 144 mg of elemental magnesium from 2,000 mg of Magtein magnesium L-threonate. The larger 2,000 mg figure is the weight of the full compound, not elemental magnesium.

Magtein is the branded magnesium L-threonate ingredient used in Brain-Mag Pro. It should not be confused with magnesium glycinate, citrate, or oxide, which are chemically different magnesium salts.

Not necessarily, because its three-capsule serving contains 144 mg of elemental magnesium. That is much less elemental magnesium than the 2,000 mg compound weight printed prominently on many L-threonate labels.

ProHealth markets Brain-Mag Pro for cognitive support, and Magtein has been studied in controlled trials, but results do not guarantee an individual benefit. It is a dietary supplement, not an approved treatment for dementia, memory loss, or another neurological disease.
