Growing up as kids, you always heard about drinking milk to get your calcium and eating bananas to get your potassium. But something you never really heard about is getting enough of a different mineral…Magnesium. Which is crazy when you think about it. Health surveys have found 48% of Americans of all ages are not consuming the recommended amount of magnesium in their diet [1].
Magnesium might be the unsung hero of all the minerals. It’s a cofactor in over 300 enzyme systems and plays a role in important processes including:
- Protein synthesis
- Muscle function
- Nerve function
- Bone building
- Energy production
- Heart function
- DNA synthesis
- …and more
