Important Information About
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
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,
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.
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
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.
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.
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
