Magnesium powers over 300 enzymatic reactions in the body, muscle relaxation, nervous-system regulation, and the cascade of processes that prepare you for sleep.
Not all magnesium is created equal. Magnesium oxide is cheap and poorly absorbed (often less than 5% bioavailability). Magnesium glycinate, magnesium bound to glycine, absorbs more efficiently and is gentler on the digestive system.
DRIFT contains 75 mg of magnesium glycinate per can (18% DV). The glycine binding does double duty: it carries the magnesium and is itself a calming amino acid.
