I do take issue with taking 5,000IU daily, as I try to limit higher level supplements going through my liver.
This is news to me. Can you point to a reference that suggests that large regular doses of vitamin D3 causing liver problems? If you have one, I prefer a citation to the peer-reviewed medical literature rather than a lay explanation.
