How long after I take my Synthroid should I wait before taking vitamin B12? I take my Synthroid in the morning and multivitamin and premarin in the evening. I want to start taking a B12 supplement in the morning but I do not want to take it too close to my Synthroid.
You should wait to take vitamins at least 4 hours if not more after meds, B vitamins are energy and should be taken before 2 if you go to bed about 10ish, otherwise they can keep you up at night. I take my meds about 6:30 in the morning and then take my other vitamins about 2.
Thanks dea4! I take my meds about 5am (when I get up). I took the B-12 at about 9:30 this morning so hopefully this will continue to work out. Do you know if the B-12 should be taken with or without food? The bottle says with food, but other information I have read says without.
