Magnesium comes in many forms, and glycinate is the one people favour for its good absorption and gentleness on the stomach · This article explains how it differs from other forms and who it suits
Magnesium glycinate is magnesium bound to the amino acid glycine · This chelated bond makes it well absorbed and gentle on the digestive tract, so it rarely loosens the stools the way some magnesium forms do (such as oxide, or citrate at high doses) · Glycine itself is also talked about for a sense of calm, which is why it is popular before bed
1 How it differs from other forms
| Glycinate | Other forms |
|---|---|
| Well absorbed, gentle on the stomach | Oxide: poorly absorbed · Citrate: may loosen stools |
| Popular for relaxation/sleep | Citrate is popular for constipation |
2 Who it suits
- People who get loose stools from magnesium — glycinate is gentler
- People focused on relaxation/sleep
- People who want good absorption at a dose that sits well in the stomach
⚠️ It is a nutrient, not a sleeping pill
3 Cautions
People with kidney disease should be careful with magnesium supplements and consult a doctor, because the kidneys excrete magnesium · Take it as directed on the label, and if it is used for sleep it is usually taken in the evening/before bed
