Important Information About Vitamin D


Remember, Vitamin D is one of the four fat soluble vitamins D, A, K, and a. and a vitamin is a nutrient that we require in very small amounts that we cannot produce ourself, but we need it for normal growth and development. Vitamin D being a fat soluble vitamin.

And what that means is it can be stored within our body because the cells of our body is surrounded by fatty layers. And that allows for the movement of this vitamin into those cells easily and therefore easy to be stored water soluble vitamins however, they often get excreted from the body quite quickly.

That’s one of the major differences. So when we look at vitamin D, first thing you need to be aware of is that the main way that we get vitamin D is through UV exposure, or our exposure to sunlight. So this is going to be the first step in the synthesis of a precursor vitamin D

to an active vitamin D. We can get some from the food that we eat from animal and plant products, but it’s quite minimal, but I’ll get there in a second. So our exposure to UV light is going to trigger the conversion of a cholesterol that the present in our skin epidermis called 70 hydro cholesterol.

What the UV light does is it turns 70 hydro cholesterol into something called colleague Kelsey Farrell. So, colleague Kelsey Farrell we’ll now be floating around in our bloodstream. Now when it’s floating around in our bloodstream,

it’s ultimately going to get to our liver and in our liver Collie Kelsey Ferro, which is also known as vitamin d3. Still not active yet. It’s inactive. Once it gets to the liver, it comes across. Once this is produced. It then moves to the kidneys.

So I’ve got Calcifer Dale also known as 25, hydroxy, choline, Kelsey Farrell, travelling to the kidneys, it comes across another enzyme in the kidneys, which is called one Alpha hydroxylase. And what one Alpha hydroxylase does is it gives a hydrogen to the first carbon of this Calcifer deal. So now we have a molecule, which is 125.

hydroxy Cali, Kelsey, feral, which is a mouthful, but it’s also known as calcium trail. Now what we have is an active form of vitamin D. Important point, these enzymes here.

Really important because you’re always going to go through this process and turn into Kelsey for deal. This 2500 oxy colleague, Kelsey Farrell, we’re always going to go to this point when you’re

exposed to sunlight but that means this enzyme is always going to be activated Liver, but this enzyme in the kidneys specifically
it’s produced by what’s called the proximal convoluted tubule cells, this one Alpha hydroxylase

that needs to be stimulated to be active. Right. So what that means is, when you get a blood test for vitamin D, you are not actually testing getting for, because you’re always going to be producing that at all times. So that’s a good indicator of your baseline vitamin D, at least precursor.

Its whole job is to increase calcium because the stimulus will drop the mind down to release calcium and phosphate into the bloodstream. Now you may be thinking, Wait a minute, if this is breaking bone down and releasing calcium and phosphate into the bloodstream,

don’t need vitamin D for strong bones. This seems like the opposite of what we want. Alright, important point. If we have vitamin de, both this connection this bond of the two is no foreign hormone.

Broken bones will start to become brittle. Now I want to talk about deficiencies. What happens if we don’t have enough what happens if we have too much? Alright, let’s have a look.

deficiencies are important. Let me tell you why. First option. Now while it does this now, the main issue here with the deficiency is going to be the exposure to UV light. So the question then is how much vitamin D should we be having?

So somebody under one year of age, ran about 400 international units 600 international units if you’re between one to 70 years, and 800 their bone has not matured yet. So there’s a lot of collagen and brittle bones. Alright, so the best way to get away from sunlight, you will get overexposure vitamin D

from supplementation. So what happens is this, you get stones, Bones abdominal moans and psychic groans This is an old school way of remembering what happens if you have too much vitamin D stones bones abdominal bones and I think Brian let’s have a look so stones Increase The amount of calcium
