text: co enzyme q10? has any one tried these herbal tablets ,if so what do you think of the benifits.thanks i tried them when having some heart problems.  they did help and i did feel the benefits.  it's a coenzyme that your heart, especially needs.  but, the human body also produces this on it's own.  i suppose it would depend on whether or not your diet has sufficient coq10 to work.  it's expensive, but if it helps, then hey - use it. another cardiac "helper" is omega 3 and omega 6.  they're essential fatty acids and much cheaper.  my advice would be to try it.  if you feel better, then continue.
