About the old man's bad heart, I want to buy some health care products. What should I buy?

If the heart is not good, take coenzyme Q 10, which is a good cardioprotective agent and can enhance heart function. Because the human body itself can't produce that kind of coenzyme, which is the most important energy activity element of the heart and lacks coenzyme. The heart is not well protected. By supplementing coenzyme Q 10, we can improve the power of the heart and have a good effect on treating the heart.
