“…If something is driving your aldosterone abnormally high, such as a deficiency of progesterone, then the combination of high aldosterone and high salt intake will increase your blood pressure. But when your thyroid and vitamin D and calcium intake are good, that will hold down your aldosterone and progesterone antagonizes the effects of aldosterone. So that combination of vitamin D, calcium, thyroid and progesterone are the basic anti-aldosterone system and the blood pressure regulating system apart from sodium. I have high calcium according to my tests.”
