More people have heart murmurs than know they do. And Im sure there are those who take
fat burners etc and have no adverse effects.
The doc found that I had a heart murmur about 3 years ago, said that it was fine and didnt set any restrictions for it. So Ive taken
fat burners, stims, etc... with no harm.
However, it is a personal decision, and if you are worried about it consult your physician.
