There are over a dozen types of magnesium, but only a few actually work.
The problem? Most drugstore magnesium is magnesium oxide — a cheap form with only 4% absorption.
One researcher put it perfectly: "Taking magnesium oxide is like swallowing a pebble and hoping your body gets something out of it."
You see "400mg Magnesium" on the label and think you're covered. But if it's oxide, you're absorbing only 15mg of actual magnesium. The rest goes straight through you — often as diarrhea.
ProLabs uses four highly bioavailable forms — the same types used in clinical research at Harvard and Johns Hopkins.
Why does this matter to you?
Each form targets a specific system. Together, they cover everything:
- Your nervous system gets calmed (glycinate)
- Your muscles get relaxed (malate)
- Your digestion gets supported (citrate)
- Your brain gets clarity (threonate)
At a combined potency designed for real results — not just to look good on a label.
