Some nutrients are essential to our health. Therefore, they are also for our life. One of them is vitamin D. You’ve undoubtedly heard of its role in maintaining good bone health. However, another of its functions is related to the immune system. It is precisely because of its involvement in the immune response that the relationship of vitamin D with COVID-19 is being investigated.
Vitamin D And Vitamin K Essential Nutrients For Life
We find vitamins, minerals, amino acids, and essential fatty acids among the vital nutrients for life. As for vitamins, we highlight vitamin K. When we are born. We need an injection of vitamin K to avoid dangerous bleeding in the newborn. This administration is protocolized in all hospitals and ensures a good functioning of blood clotting in the baby. Due to the low sun exposure due to our current lifestyle, it is also necessary to supplement vitamin D. From the first days of life. For at least one year, babies are supplemented with a dose of 400 IU per day.
Why Is Vitamin D Supplementation Necessary
The vitamin D supplementation during the first months of life is crucial because it intervenes in:
- The development of bone through intestinal absorption and calcium fixation in bones.
- The operation of the nervous, cardiovascular, and hormonal systems.
- The increase in muscle strength.
- The regulation of the immune system.
The Role Of Vitamin D In The Immune System
It has been observed that a good Vitamin D status can offer more excellent protection and decrease the severity of acute infections. This is probably produced through the regulation of the immune system. As a result of these observations, a study was carried out at the Reina Sofía Hospital to investigate COVID-19. It was an open, randomized, double-blind study. The study’s objective was to assess vitamin D’s action on a respiratory infection associated with COVID-19.
What Studies Say About Vitamin D And Its Relationship To Covid-19
The study was conducted in 76 patients who received the same type of protocolized treatment against COVID-19 with hydroxychloroquine and azithromycin. Also, 50 of these patients were administered an initial dose of 0.532 mg of calcifediol or 25-hydroxyvitamin D and, subsequently, an amount of 0.266 mg daily.
The results obtained on the relationship of COVID with vitamin D were the following:
- Within the group supplemented with vitamin D, only one person required admission to the ICU.
- In the group that was not supplemented with vitamin D, 13 people required intensive care.
- The trial showed that the administration of high doses of Vitamin D during the hospitalization significantly reduced the severity of the disease.
It is important to note that randomized clinical trials, such as the one mentioned in this article, have a high scientific evidence level. However, further systematic reviews and meta-analyses are also necessary to reach the maximum level of scientific evidence.
Where Can I Get Vitamin D From
For this reason, an exposure of about 20 minutes a day and without the use of a protector could help us reach normal levels. Although there are foods such as eggs, oily fish, mushrooms, and dairy that contain vitamin D, the supply is usually insufficient. As for the rest of the vitamins, such as A, C, and E, they also positively affect our health and our immunity. However, these are easier to obtain through diet.
So Do I Have To Take Vitamin D Supplements
If you are an adult and think that vitamin D will prevent the spread of COVID 19, remember that this is not going to be the case. However, having good blood values in blood, between 30 and 50 ng/ml, will help you improve your immunity and health if there is a deficiency. From there, assess supplementation with health advice accordingly. If you have a baby, follow the prescriptions given to you at the hospital for vitamin D supplementation in the first year of life. Later, consult with the health professional about the continuity or not of the supplementation.
Finally, it must be borne in mind that Vitamin D is a fat-soluble vitamin. This means that it can cause toxicity if we consume supplements in excess. Excess vitamin D can cause gastrointestinal symptoms such as constipation and vomiting and a high concentration of calcium in the blood. For this reason, the recommendation is that you go to a healthcare professional before taking any supplementation.
