400 mg of elemental magnesium per serving, from a 2000 mg blend of four magnesium compounds. The full breakdown is on the Supplement Facts panel.

Different magnesium compounds are absorbed differently. Using four gives broader coverage than betting everything on one.

The blend is mostly bisglycinate, which is bound to glycine and is the gentlest of the common forms. Citrate is present but is not the main ingredient.

Give it two to three weeks. Magnesium is a mineral your body builds up — it isn't a sedative and it won't work like one.

This is a food supplement and does not replace a varied diet. If you are pregnant, nursing, or taking medication, talk to your doctor before starting.
