Supplement FAQ

Can magnesium upset your stomach?

Yes, some magnesium forms are more likely to affect stool or digestion. Form, dose, and sensitivity matter.

Short answer

Magnesium can cause digestive changes, especially at higher doses or with forms commonly associated with stool effects. Citrate is often compared for digestion-oriented use, while glycinate is commonly compared for gentler tolerance. The label's elemental magnesium amount matters more than the front-label compound weight.
