Magnesium glycinate and magnesium chloride are different magnesium compounds used in different product formats. Glycinate is common in oral supplements; chloride is used in some oral products and many topical formulations. Neither is automatically better for everyone.
What is magnesium glycinate?
Magnesium glycinate combines magnesium with the amino acid glycine. It is usually sold as an oral supplement and is often selected for its measured dosing and digestive tolerability.
What is magnesium chloride?
Magnesium chloride is highly soluble and is used in tablets, liquids, bath products, sprays and roll-ons. In topical products, the concentration describes the formulation, not the amount proven to enter the body.
Can a topical magnesium chloride product replace an oral supplement?
Current evidence does not support treating a topical product as a dose-equivalent replacement for an oral supplement or clinician-directed treatment.
Which should you choose?
Choose based on the purpose and advice you have received. An oral supplement may suit someone who needs a measurable intake. A topical roll-on may suit someone who wants a convenient external body-care ritual.
Safety
Consult a healthcare professional before oral supplementation if you have kidney disease, take regular medicines, are pregnant or breastfeeding, or have been advised to restrict magnesium. Patch test topical products and avoid broken or irritated skin.
