I am a 23 year old female; 5' 3/4" and weigh 158lbs. I have aortic valve stenosis (congenital) which was corrected in 1999 with the ROSS Procedure. I have a RV-PA conduit from that procedure and have been stable ever since. Rest of my medical history is uneventful other than severe preeclampsia with my daughter in 2007. Is it safe that I take Oxy Elite Pro? I need to loose weight and I lost 35lbs but cannot get further despite diet and exercise. I know a few people who have used this product and have been successful (and I have been researching since I am a RN). Is it okay?
