I have PCOS and have been taking metformn for insulin resistance. I started taking Oxy Elite Pro this week, without taking metformin. Is it safe to take both the metformin and Oxy Elite Pro? Im am a 42 yr old female. 139 lbs, 5'2", and other than the PCOS i am healthy. The PCOS makes it very difficult to lose weight, even though i eat well andexercise regularly. That's why I'm trying the Oxy Elite Pro.
