Advanced Amino Formula has improved my health I will tell you how they make me feel. I do suffer from heart failure and have had a stroke which results in me being on various medications and have an implanted defibrillator. The products I now take have had an immediate effect on how I feel and function. I now exercise at a much higher level and bike, swim, speed walk and do weights. My goal is to soon be able to run, which was my first love. Oh also to play tennis with my wife which I never believed possible until I started take Bionutritionals.
