I don't think grapefruit on its own effects cholesterol.
With Statins its like using LP gas and then adding O2, the grapefruit somehow makes the statins much much more effective. Makes me wonder why they don't lower the statin does and include the quinine.
I'm no Dr., but everything I read says too much Statins can seriously mess you up, goes after some kind nerve stuff. Google Lipitor Shuffle sometime.
