done lots of studies on this one, CoQ10!
here's the latest word:
there are no "statistical absolutes" about CoQ10's effectiveness OR ineffectiveness.
it is most likely not harmful, except when taken in large doses, although it may indeed
have some negative interaction with blood thinners such as wayfarin.
but the latest studies ALL show that CoQ10 may have a characteristic previously
unrealized: it is beginning to look like it has tremendous benefit, tremendous, in
controlling the muscle damage/problems that patients have when taking statins.
a small dose of CoQ10 may help chemically counterbalance whatever it is in
statins that causes muscle problems.
