Two to three thousand units of vitamin D a day can increase our defenses against various diseases. “Populations with lower levels of vitamin D generally have a higher risk of death. Vitamin D supplementation has a positive effect on upper respiratory diseases, so it can be assumed that it may also have a stimulating effect on the immune system against COVID-19 infection, “said Tamás Masszi, director of the Department of Internal Medicine and Hematology from the University of Semmelweis, in an article on the university website. In summer, 10 to 30 minutes a day is enough to cover the daily amount of vitamin D, but this vitamin must be replenished in autumn And winter Pharmacist Judit Wise told Origo that significantly more vitamin D is sold in pharmacies than before, many know that this vitamin can also protect against viral infections.
Where vitamin D levels are lower, the risk of death is generally higher
If we spend a quarter or half an hour a day in the summer and take 1000-2000 units of vitamin D per day as prescribed by a GP in the winter months, our vitamin D levels will stay in the proper range throughout year. Said Tamás Masszi, Director of the Department of Internal Medicine and Hematology at Semmelweis University, on the Semmelweis University website. He added that vitamin D is primarily responsible for healthy bone structure, but it also plays an important role in muscle function, for example.
With the beginning of the autumn and winter seasons, in the period between October and March, according to surveys, 9 out of 10 people in Hungary develop vitamin D deficiency.
This can also be observed in other temperate countries. Vitamin D deficiency is caused by a typical lack of sunlight from late fall to early spring.
Vitamin D is also known as hormone D, due to its mechanism of action.
With food, it is essentially difficult to enter the body: of the two thousand units needed per day, we can only provide up to 80 units with meals.
When exposed to sunlight on our skin, our own bodies can produce it from vitamin precursors. This is because ultraviolet radiation, which reaches our skin, is the main responsible for the level of vitamin D in our body.
“Vitamin D is primarily responsible for healthy bone structure, but it is also important for maintaining muscle strength, for example. Its receptor is present in almost every cell in the body, “said Professor Tamás Masszi in an article from Semmelweis University.
Stressed that Compared to data from 4-5 years ago, the level of vitamin D intake in Hungary has tripled. This is also important because this vitamin can also contribute to the body’s ability to fight disease.
“Numerous international studies have shown that populations with lower levels of vitamin D generally have a higher risk of death. Vitamin D supplementation has a positive effect on upper respiratory diseases. Colds, flu and other milder upper respiratory illnesses, also caused by coronavirus, are more common in winter, and lower levels of vitamin D can play a role as well. “In other words, vitamin D appears to protect against respiratory infections and is also known to have a positive effect on lymphocytes and the production of anti-pathogenic proteins.– said dr. Tamás Masszi. Consequently, it is hypothesized that vitamin D supplementation may also have an immunosuppressive effect against COVID-19 infection. The specialist added.
Many more people in pharmacies are looking for vitamin D.
“More and more people are aware that vitamin D supports the functioning of the immune system, and the demand for vitamin D in pharmacies has increased steadily in recent years.” – Judit Bölcs, pharmacist and owner and manager of Korona pharmacy in Budapest, told Origó. He added: who can, take vitamin D in the autumn-winter period.
We also asked if it was possible to take higher doses of this vitamin. The pharmacist replied that vitamin D3 is well absorbed, it is not excreted like vitamin C, so it is not worth taking it in doses greater than 2-3 thousand units a day.
“We can replenish vitamin D in the body with two or three thousand units a day. Take no more. There are very large amounts of vitamin D tablets in pharmacies, of which you only need to take one every week or two. I don’t recommend this because you can forget to take your weekly dose and may even take more than you should. Vitamin D can be overdosed and this can have a variety of symptoms ”, emphasized the pharmacist.
If someone takes too much vitamin D for weeks or months, calcium builds up in their body. Specific symptoms may appear during metabolism.
“An overdose of vitamin D can have a detrimental effect on the digestive system. It cannot break down the body’s fat-soluble vitamins and muscle weakness, kidney damage, stomach and intestinal discomfort can occur. ” Judit Wise said.
