This is the topic of the day, before jumping on to the topic, I forgot to mention one thing in my previous video that Vitamin D is associated with immunity and it has a very close connection with immunity.
The immune cells are dependent on Vitamin D for their proper functioning if it isn't available; We are going to get a lot of infections, I won't name all the infections but if it's not there properly it can even lead to malfunctioning, it can lead to autoimmunity, our own antibodies may start to target our own body, so that's why the diseases like systemic lupus arithmetic called SLE connective tissue diseases or under many other autoimmune diseases have been linked with low Vitamin D levels.
Once again research is against and for it but it makes a lot of sense when we go into the detail. Now coming back to the topic of the day is what is the real mechanism, how is the Vitamin D made by almighty.
Vitamin D is made in three steps
- First is in the skin.
- second is in the liver.
- Third is in the kidney.
In the skin is the sunlight and the UV light, the ultraviolet light touches the skin and it converts something into a molecule- 70 hydrochloric stroll and then it moves into the liver where it is hydroxylated at 25 positions and in the kidney at one position or alpha hydroxylation, we call it now these technical or fancy names you don't have to remember it, you just need to remember as a combination - teamwork of skin liver and kidney. In that Vitamin D is made once Vitamin D is made it's being utilized all over the body, in all the nucleated cells of the body, there is a receptor called Vitamin D Receptor (VDR), it goes there and then it does the necessary wherever it has to function, it does what is the function of Vitamin D, I have already told in my last video in detail, in this article now I am going to talk about what are the causes of Vitamin D deficiency, reasons behind Vitamin D deficiency.
Let's start with skin, there is inadequate exposure to sunlight or the skin, the reasons are so many, we are living in a place where the sun explosion isn't sufficient, it's mostly raining, it's cloudy in winters, the sun is scarcely available or we are not really familiar with going out in the sunshine.
Once we are in the sunshine, 200 international units of Vitamin D are formed within a few minutes, if we are exposed to sunlight, the recommended daily allowance the RDA is usually 600 internationals for adults so the optimum amount of time that you should spend in the sunshine is not really in a consensus.
Next, if the skin goes fine then malabsorption- we are having some kind of problem within the stomach and we are not able to absorb the Vitamin D from our diet, this may be true in terms of so many conditions that cause diarrhea.
If you're having a kid or you or any patient is having a kidney failure weak kidneys that will lead to the decreased third step of Vitamin D manufacturing and Vitamin D will need to be supplemented in that case so these are the general things that need to be taken into account in order to understand what are the actual things that would lead to Vitamin D deficiency.
Now the best treatment:
The best treatment takes plenty of Vitamin D when you can take it and the doctors haven't asked you to stop taking egg yolk and milk and all that due to some reason and there are very few reasons that we stop these things and if you take sufficient amount of these things you don't need any medicine, yogurt is a good source of Vitamin D.
