So it's important for the muscles to work, for nerves, for neurons to fire, enzymes to be released, hormones to be released, clotting.

But I can show you how important calcium is more importantly than telling you.

So if you remember a time when you hyperventilate, when you breathe really, really fast, you're blowing off all your carbon dioxide.

And you make your blood alkalemic.

You have respiratory alkalosis.

Okay.

And then what you notice physically is you get pins and needles and tingling in your fingers.

Yes.

Okay.

And that's because of the calcium.

So what happens when you blow off all your carbon dioxide and your blood becomes alkalemic is you bind more of your calcium to proteins, albumin, and less is free.

And what that does is it lowers your threshold potential and increases your neuron excitability.

So this level of calcium is super important.

So it's very, very tightly regulated and very fiercely defended by our hormones.

So vitamin D is called a vitamin, but it's actually a hormone.

It's a steroid hormone.

We get vitamin D mainly from the sun.

So sunshine irradiates dehydrated cholesterol in the skin.

And that goes to the liver to get activated.

And it goes to the kidneys to get activated.
