One common question people ask before starting bioidentical hormone replacement therapy is whether they need to stop taking other supplements in order to let the bioidentical hormones work optimally. Of course the short answer to the question is to run the list of supplements you are taking by your bioidentical doctor and get her or his advice. But there are some guidelines you should use and talk to your BHRT doctor about, so this post should help guide your conversation.
First, it is a little less likely that supplements taken for issues completely unrelated to hormonal issues are less likely to interfere. This is not an absolute, and you still need to fill in your bioidentical hormone replacement doctor on what else you are taking, but you’re more likely to get a positive answer if the supplement is doing something else. This is not as much because of concern that it will be hard to know the effect of BHRT if you continue taking the supplement (though this could be an issue), but more because two different supplements for the same issue have a higher likelihood of interaction effects.
Second, the supplement you are currently taking may have a profile that suggests it is more likely than others to cause interaction effects. For one reason or another the supplement might work in a way that is more likely to have a negative effect on any other supplement, whether bioidentical hormones or something else. The opposite could be true of course, and you may be taking a supplement that rarely interferes with other supplements.
Finally, you may need to stop taking your other supplement because your doctor wants to be sure he or she gets a clear picture of exactly what the bioidentical hormones are doing, and as a scientist she or he does not want anything interfering with that picture, at least at first.
