I have been using Cardio Vital from Biowell for the past six months. I had a clogged artery which required an angiogram and stent placement. Fortunately, there was minimal damage to my heart. I am up to my eyeballs in meds...to slow down heart, to prevent the body from manufacturing cholesterol, a beta blocker, plavix, aspirin, etc. I, like zillions before me, have been indoctrinated with diet advice...mainly low fats, cholesterol, etc. I am in a cardio rehab (exercise) course for 12 weeks. In spite of all of the above, open heart surgery and stent implant patients still continue to have clogged arteries. Re-occlusion is very common. I have an Oriental doctor who prescribed Cardio Vital for me in an attempt to prevent any further clogging. He claims it will clear any build up. All I can say is, so far, so good. Only complaint I have is that my physician started me off on product that expires in 2012. When I started ordering it myself, I received product with expiration date in 2011. The taste of the older product is only half as strong. Who knows if it is as effective?
