Grapefruit and Heart Medication

Customers often ask us how grapefruit affects heart medication

To reiterate, we highly recommend that all people who are prescribed medications to have a conversation with their doctor or pharmacist around the specific medication(s) they are taking and the foods/drinks that they should be avoiding.
