1,035mg of MOXIO Zonated Magnesium is the star of the show. 246% of your daily needs, in the exact form your body actually recognizes and uses. Citric Acid is the key that unlocks the magnesium so your body actually absorbs it (this is what cheap tablets miss). Potassium Citrate is the balancer that keeps your energy steady while the magnesium goes to work. The capsule itself is plant-based cellulose. That's the whole label.
