How to Choose the Right Magnesium Glycinate
1) Look at elemental magnesium
The number that matters is elemental magnesium (the amount of actual magnesium you get per serving). In the table above, you’ll see options ranging from 150 mg to 500 mg per serving.
2) Consider your stomach sensitivity
Many people choose glycinate because it’s often easier on digestion than some other forms. Still, everyone is different—start with a smaller serving if you’re sensitive.
3) Decide your “best fit” goal
- Simple daily support: a straightforward bisglycinate capsule product.
- Higher-dose preference: higher mg per serving, if appropriate for you.
- Convenience: fewer pills per serving (even 1 tablet).
- Powder: flexible and easier if you dislike capsules.

Possible side effects can include stomach upset or bowel changes (more common with some forms and higher doses). Be cautious and speak with a clinician if you:
- Have kidney disease
