MRM Nutrition Magnesium Glycinate

The exact amount depends on the current bottle and serving size, so shoppers should use the Supplement Facts panel rather than the larger magnesium-glycinate compound weight. Elemental magnesium is the number that should be compared with other products and with a clinician's dosage advice.

Some magnesium glycinate products use magnesium oxide alongside the glycinate complex to increase the elemental-magnesium content. Check the current MRM ingredient list for both forms because retailers sometimes retain images from older formulations.

Glycinate is often chosen because it may be gentler on the digestive system than magnesium citrate, which is also used for its laxative effect. Any magnesium supplement can still cause diarrhea, nausea, or abdominal discomfort, particularly at higher doses.

Magnesium can interfere with absorption of medicines such as levothyroxine and certain antibiotics if taken too close together. A pharmacist can provide the correct spacing for the specific drug, and people with kidney disease should seek medical advice before supplementing.
