Can those of you on NDT give me advice please? How do you find a split dose rather than the full amount in one go? I understand that the problem with two goes in a day can be food/supplement times but I am also unsure of the reasoning behind it. Is it due to the T3 content that I will not have had before? I am currently on 100mg of levothroxin. Second question: I am on antibiotics for the next week. Will that interfere with my NDT? Should I wait to finish the course before starting NDT or will it not matter - this has been a two week course for a gut bug.
