Magnesium drives ATP production — the energy currency your muscles run on — and plays a critical role in muscle contraction, recovery, and sleep quality. The bisglycinate form is bonded to glycine, which allows your intestines to absorb it significantly better than cheaper forms like oxide or citrate.

Mix one scoop with 8 oz of water once or twice daily. Many athletes take it in the evening to support sleep and overnight recovery. If you're using it twice daily, a morning dose and an evening dose works well.

Most drugstore magnesium is magnesium oxide — it has low absorption rates and often causes loose stools. Bisglycinate bonds magnesium to an amino acid (glycine) your gut readily absorbs, delivering more magnesium to your cells with far less GI irritation.

It's specifically formulated to minimize GI distress. The bisglycinate chelate is one of the gentlest forms of magnesium on the digestive system, which is one reason it's preferred over magnesium citrate or oxide for daily supplementation.
