@wellpickedapp: Seven supplement pairs that want space, sourced to NIH: iron and calcium at different times of day. Levothyroxine not within 4 hours of calcium carbonate. Magnesium 2 hours before or 4 to 6 hours after cipro or doxycycline. Zinc over 40 mg a day for weeks lowers copper. Fish oil plus a blood thinner, greens powder plus warfarin, St. John's wort plus many meds: ask first. Save it. Wellpicked checks your stack against your meds, free. Not medical advice. #supplements #vitamins #magnesium #iron #calcium #levothyroxine #pharmacist
