A friend of mine, age 55, who is otherwise fully healthy, has an issue of serious heart palpitations.
He used to have an episode once a week on average, but lately it sometimes happens that he is having one 3 to 4 times a day, lasting around 10 to 15 minutes.
He has been turned inside out by cardiologists, but they cannot find any cause, let alone a cure.
Is there any supplement my friend can take that will not harm him, but probably will control this problem?
Thank you in advance for your advice.
