Vitamin D is said to protect against many diseases of various kinds – including obesity, depression or even cancer.
However, one of the most searched for information is the relationship between vitamin D and immunity.
Is vitamin D worth supplementing additionally for immunity?
Vitamin D affects the body’s normal development and function.
It is naturally synthesized and taken up by the skin, which is exposed to the sun’s ultraviolet rays.
The differences in the color of human skin, moreover, are due precisely to vitamin D, or rather to its deficiency.
Originally, humans had darker skin, but as a result of the migration of peoples to Europe and further north and east, they began to experience vitamin D deficiencies. Our bodies responded by significantly reducing the level of melanin in the skin, resulting in a much lighter complexion.
All this in an effort to ensure that humans can acquire as much as possible of the valuable vitamin D, which is also important for the immune system.
Vitamin D and immunity – how does it work?
Vitamin D is responsible for a number of factors and is involved in various physiological processes.
It has a huge role in the process of gene regulation, as well as in the building of the skeleton.
It is a protective factor in the occurrence of various diseases, including but not limited to diabetes, cancer and diseases of the circulatory system.
Moreover, vitamin D directly affects the extent of absorption of calcium and phosphorus from the gastrointestinal tract.
It takes an active part in the process of cell division and has an impact on the immune system.
Indeed, vitamin D receptors are found in many elements of the human body.
This confirms its great influence on the functioning of various organs.
Thus, it can be said that vitamin D affects immunity in the same way that the food consumed affects energy capacity.
Effects of vitamin D deficiency in the body
It is estimated that about 3/5 of babies born into the world are vitamin D deficient.
For this reason, so often doctors recommend that pregnant women take vitamin D supplementation for immunity.
Its deficiencies will consequently mean a much higher level of illness from various viral or bacterial infections.
Another consequence of vitamin D deficiency in the body will be frequent pains in the muscles.
Although the research is still ongoing, scientists are beginning to see a link between the lack of sufficient amounts of vitamin D and the formation of some varieties of cancer.
In this context, therefore, it can be said that vitamin D is certainly one of the most important in terms of support for the human immune system.
However, the disastrous consequences of vitamin D deficiency do not end there at all.
As we mentioned, it is also involved in the formation of bones.
So it’s easy to guess what the consequences of vitamin D deficiencies are in this regard.
The formation of conditions such as osteoporosis, osteomalacia and various types of rickets has already been scientifically proven.
Unfortunately, these are quite common consequences of vitamin D deficiency, which our body needs both for immunity and to take care of bone health.
Immune support with vitamin D – what should I pay attention to?
A healthy diet, unfortunately, will in no way support immunity. Vitamin D, its production in the body, does not have any relation to what we supply to the digestive tract.
The natural process of vitamin D production in the human body occurs through dermal synthesis.
So what should you do to support immunity with vitamin D?
First of all, get out in the sun – the more often, the better!
Today’s overworked and sedentary lifestyle, usually indoors, is not conducive to the synthesis of vitamin D. Therefore, with the solution comes the purchase of vitamin D supplements for immunity.
A number of preparations can be recommended here, but instead, everyone should perform simple laboratory tests at the outset.
These will allow you to find out if you have a vitamin D deficiency, and if so, what dose of vitamin D you should supplement!
