How do I know if the tamoxifen doesn't interact with zeolite?

Zeolite. Aims to attract "+ charged toxins" and has "no side effects. However, no one has studied what it does to people taking any drug. You can only "know" if there is a specific study that compares: tmx levels +/- zeolite, and benefits at 5 and 10 years. Thus, i'd lay off the zeolite if it were me, but the chance of harm is far-fetched.
