Scardycat, I take 4 directly for my heart. CoQ10, Carnitine, D-Ribose and Hawthorne extract. There is one Carnitine that is supposed to be specifically fo your heart, but rich tnow I have Carnital. D-Ribose is a 5 sided sugar specifically for muscles, the heart is a muscle so it is for your heart. Hawthorn is known worldwide for heart failure. Can't explain the other 2, but you can look them up.
