Hey there. I'd hesitate to give you medical/dosage advice since I'm not a trained medical professional. But IF you were trying to match my dosage what I would do personally is: - Split the magnesium pill if possible - Double check the directions on the bottle. Mine is a 250mg dosage per 2 magnesium capsules. Which is practice is 125mg per capsule. Some of these supplements are misleading like that Hope I've been able to help
