Vitamin D Benefits, Deficiency and Covid-19: Vitamin D is the most underrated and controversial vitamin sold. In fact; it’s not even a vitamin. Due to the fact, as opposed to normal vitamins, the human body manufactures it for itself. It is similar to a hormone that contributes to the production of active D2 and D3, the latter is more active when it comes to biological activity and effectiveness.
Our body creates most of our vitamin D from direct sunlight on our skin. Unfortunately, from late autumn until early spring it is impossible to provide a sufficient amount of vitamin D. The increase risk for certain illnesses in this period is often associated with a possible vitamin D deficiency. In most parts of the world, it is impossible to satisfy vitamin D needs solely from sunlight.
The Consequences of Vitamin D Deficit
Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorous and facilitating normal immune system function. Getting a sufficient amount of vitamin is important for normal growth and development of bones and teeth. As well as improved resistance against certain diseases. Vitamin D deficit leads to bone loss and bone density and this increases the risk of bone fracturing. According to studies vitamin D deficit contributes to heart problems and heart failure. It increases the risk of high blood pressure and hardening of the arteries. It can also cause kidney problems, breast, and colon cancer. Vitamin D deficit has been proven to be a contributor to a lot of other health problems for people of all ages. Many lifestyle and environmental factors can affect your ability to get sufficient amounts of this vitamin through the sun alone. These factors include:
- Use of sunscreen
- Spending more time indoors
- Working longer hours in offices
- Living in big cities where buildings
- Blocked sunlight or night shift workers
The Controversy on Vitamin D:
Here starts the controversy regarding vitamin D dosages. The recommended daily intake of vitamin D is around 400 iu. It’s impossible to state an exact dose due to maybe conspiracy theorists. Pharmaceutical companies state higher doses because of the effectiveness for illnesses and prevention of a lot of those illnesses.
The story starts from 1926 when the first official controlled laboratory studies were done in America. Firstly, they changed the way of measuring from mg to International units (IU) and the reason for that; so they say, was when measured in IU’s it seems to the common public a higher amount than when measured in mg. The reason for doing that is, if the user supplemented vitamin D with the correct amount, that this will prevent a lot of illnesses developing which in turn will hinder the sales of medicines which will affect their profits. They are still using the 1926 results of the case studies, which is outdated due to the way of making Vitamin D supplements now compared to then. The daily minimum nutritional intake of Vitamin D among European nations is 400 IU and experts say that should not exceed 4000 IU.
While you may get enough vitamin D if you eat a very balanced diet you may need to take a vitamin D supplement. For instance if you’re involved in sports, work indoors or at night and during the winter months (october-march).
Higher quantities of this vitamin can be found in salt water fish like salmon and cod liver oil, while present in egg yolk, milk, cereals, yoghurt, orange juice and liver in smaller quantities.
Athletes that train on a regular basis will require more than a normal person and vitamin D will help their performance immensely no matter if they were training to increase muscle mass, fitness or strength Vitamin D will play a very important role in their goal to improve and stay healthy. So people, remember to take your Vitamin D.
Vitamin D is important for our immune system. We are more likely to succumb to colds and flu if we have a vitamin D deficiency and we are at greater risks of catching other infections, particularly of the respiratory tract.
Our immune system is made up of 2 types and they are as equally important as each other. The Innate system is for the rapid response in fighting infections. The adaptive system is responsible for the production of antibodies and vitamin D modulates both systems.
Vitamin D and Covid-19: I guess it had to happen, many vitamin companies had to jump on the bandwagon promoting their vitamins that boost the immunity system against the war with covid-19. While vitamin D is great for all the reason that I have outlined in this article there simply is no scientific evidence that any vitamin can help boost your immunity against covid-19. It can only be a good thing by taking extra vitamins; please don’t for one minute think that you are less likely to catch covid-19 having taken vitamins such as vitamin D, a vaccine is the only thing that will do that. The Controversy on Vitamin D has now been put to bed.
