Your body does not typically need supplements. A normal diet consisting of a variety of foods is sufficient.
While most supplements will be harmless, and will not interact with your medications, they have not been studied, so we recommend you do not take them during treatment.
If you insist, take them at the opposite end of the day to the time you take your medication.
Please use the drug interaction checker here to check anything you are taking, or plan to take will not interact with your treatment.
