Using a good grade of sea salt can be very helpful with iodine and other minerals. Most people are also very to extremely low in both magnesium and potassium, both of which regulate hearts and minds. Most people also take too much calcium and don’t balance it well with their other mineral intake. Calcium causes plaque build-up and if you are getting proper amounts of calcium from foods (like raw milk and other dairy products) you really don’t need excess calcium from supplements. That’s just my opinion but it does explain why “medicine” needed to create a calcium channel blocker, non?
