Can I take multi-vitamins if I am doing chemotherapy?

Hi,We recommend against using multi-vitamins to people doing chemotherapy since some components of the vitamin can have an antioxydant activity. This is only a theory, since there is no clear data that using both at the same time can reduce chemo effects.That being said, I think it is fair to get vitamins from food. By doing so, we can be certain that the quantity is more physiological.Have a great day,Alexandre Chagnon, pharmacien
