Doesn't matter now: But it might depending on what the oncologist decides to do next. The supplement you are taking does not interact with Femara (letrozole) but they might want you to stop it when they change treatment. Good luck to you!

Astaxanthin: I will recommend stopping astaxanthin which is a carotenoid but also a potent antioxidant. How Femara (letrozole) or Letrozole interacts with this compound and because of the super radical and antioxidant effects it can potentially make Femara (letrozole) less effective is possible. There is no proven benefit of this in breast cancer. Hopefully this helps.
