🔬 The science, kept simple
Magnesium helps more than 300 enzymes do their work, from turning food into energy to relaxing muscle fibers after they contract to steadying nerve signals. It sits at the center of the chlorophyll molecule, which is why green leaves are such a dependable source.
Why you need it: Relaxed muscles, steady nerves, sound sleep, strong bones (about 60% of your magnesium is stored there), and normal blood sugar handling.
Daily target: About 400-420 mg a day for men, 310-320 mg for women.
📖 In Scripture
Every green leaf runs on magnesium... it is the atom at the heart of chlorophyll. 'Behold, I have given you every herb bearing seed' (Genesis 1:29) turns out to be a magnesium prescription.
