Is maca root and evening primrose oil safe to take while having a copper iud? will it affect the effectiveness?

Maybe (not) . . .: Both maca root & evening primrose oil have been around for ages & used for various conditions. However, there hasn't been very many studies on safety & efficacy, certainly not on various combinations for interactions.

Totally safe: While several medications can interact with levonorgestrol-secreting iud's, i know of no supplements or medications that affect the effectiveness of copper iud's.
