2000 mg Vitamin C
500 mg Magnesium
a Centrum Multi
120 mg co enzyme Q-10 (which I think is the most important)
I also take a low dosage high blood pressure med. I am not really sure at what rate a teenager would progress, but I would say keep him active, i.e. cardiovascular activites and moniter his diet. Low sodium, fat, and cholstrol. No matter what even if that valve needs to be replaced in the future you want him to have a healthy heart. Best of Luck.
