Hi - I take Ellura to help prevent UTIs (which I was getting about once every 4 weeks for over 6 months). It helps a lot but I just noticed that it has some weird ingredients. I'm on Day 13 and don't want to start over and really want to stay on this medicine, but I want to make sure I am really getting all the benefits of the program. Thoughts? The ingredients in Ellura are Proanthocyanidins (from Cranberry juice concentrate extract powder), gelatin, microcrystalline cellulose, magnesium stearate, and silicon dioxide. Thanks.
