Curios we should have such a hormone calcitonin to lower calcium levels but helps explains how important it is to keep the blood concentration within a narrow range. Calcitonin is excreted by the thyroid gland. It lowers the blood calcium level by acting on the osteoclasts (perhaps osteoblasts) in skeletal Read more…
We are, for most of us or soon to be, past the age where we could die at a young age (though with optimal doses and blood levels I think what constitutes young age will have to be reconsidered). Thus, this is coming back to hurt us. That is inadequate Read more…
Thus, the skeletal bone is a huge bank to allow the rapid and large as needed release of in this case calcium carbonate and other substances to neutralize the excess acid. Which maintains a neutral Ph. This release through the vitamin D3’s activated-fast hormonal pathway is body’s main way to Read more…
So, these three areas-kidneys, small intestines and skeletal bones are where calcium comes into or leaves the blood, think of them as gateways. Then there are I believe three states to these gateways, either activated-fast, active-slow or passive. The active form of vitamin D3 acts on these areas in both Read more…
As the concentration of the blood form of vitamin D3 rises at some point again around blood concentrations of 300 ng/ml or higher, the blood calcium levels will start to rise. Prior to this point as the amount of calcium in the blood rises the hormonal system, reduces then stops Read more…
