I didn't say taking calcium/magnesium, and potassium together were bad. I didn't say taking them wouldn't help hypertension. I said they need to be taken with vitamin D as vitamin D regulates calcium levels and function in the body.

Calcium function is dependent with vitamin D, magnesium needs to be balanced with calcium, potassium needs to be balanced with magnesium.

I looked at your cites. Most seem to be a rehashing of current theory and some of it i.e., eat plenty of grains, get most of your vitamins from food, lose weight, cut back on salt while standard dogma is not particularly helpful. I'm sure it's very readable. But as you noted yourself only some people are salt resistent and sometimes drastic salt reduction can cause problems.

A lot of supplements are interactive and depend on each other. Upsetting the balance of that interaction or leaving a necessary component out can cause problems, i.e. palpitations.

In the case of these supplements vitamin D should be part of the team.

That's what I was saying.

Oh and the most CoQ10 I saw recommended was 50mg twice a day. That amount won't do much for the heart. Don't get me wrong, anything helps I'm sure but that amount while slightly protective won't reverse any damage.
