Wondering if it is ok to take my armour thyroid medication with other vitamins on an empty stomach at bedtime? Those other vitamins would be Vitamin D3, a Liposomal Vitamin C capsule, Selenium, Glucosamine Complex and a multi-vitamin without iron. Once when I refilled my Armour thyroid precription there was a warning label attached that said not to take this medication with vitamin/mineral supplements... that is the reason for my question.
