Safety, Side Effects, and Who Should Be Careful
Magnesium is one of the safest minerals when used sensibly. The most common side effect is loose stools if you go too high too fast.
Avoid high-dose supplementation or consult your doctor if you have:
- Kidney disease
- Myasthenia gravis
- Extremely low heart rate or heart block
Always choose third-party tested brands (USP, NSF, or ConsumerLab approved).
