The British government recently announced that it will provide free vitamin D supplements to more than 2.5 million elderly, weak, and frail high-risk people in England so that they can make up their needs in the winter.
Vitamin D helps maintain the health of bones, teeth and muscles.
Human skin synthesizes vitamin D through sunlight, but the elderly and people with dark skin often need additional supplements, especially during the new crown epidemic, people stay indoors for longer.
British health officials say that even in the normal winter, everyone should take 10 micrograms of vitamin D every day between October and March.
Therefore, all high-risk groups, including nursing homes, will receive free government vitamin D supplements this winter.
In fact, the British National Medical Service System NHs has previously recommended that vitamin D supplementation is appropriate when the sun is reduced in winter and people spend more time indoors. The recommended amount is 10 micrograms per day for adults.
As mentioned earlier, vitamin D is very important for maintaining healthy bones, teeth, and muscles. If vitamin D is lacking, it may cause rickets in children, and osteoporosis in adults.
Vitamin D should be supplemented in winter
Dark-skinned women are more prone to vitamin D deficiency
In addition, studies have shown that vitamin D can enhance immunity and help prevent infection.
For example, some studies have shown that when we are suffering from the common cold and flu, adequate vitamin D levels in the body can help recovery, but the research evidence in this area is sometimes not always consistent.
Does vitamin D help prevent new crowns?
According to a research evaluation conducted by the National Institute of Health and Service Optimization (NICE), there is no effective evidence that vitamin D supplements can prevent or treat the new coronavirus.
However, experts believe that maintaining a normal level of vitamin D in the body during the new crown is beneficial to people’s overall health.
Vitamin D is added to some breakfast cereals
Some researchers even believe that the poor treatment effect of some new crown patients may be related to insufficient vitamin D in the body. But the problem is that some other underlying diseases, such as heart disease, may also affect the treatment effect of new coronary patients, so it is difficult to make a conclusive judgment.
Rhodes, Honorary Professor of Medicine at the University of Liverpool, said vitamin D has anti-inflammatory effects. Some studies have shown that it can reduce the overreaction of the human immune system to the virus.
This may be especially critical for those critically ill patients with new coronary disease, because the “cytokine storm” initiated by their immune system to fight the virus often causes severe lung damage. Of course, more research is needed in this area.
Is more vitamin D the better?
Should more vitamin D be added, the more the better?
Experts say that although vitamin D supplements are safe, don’t overdo it. Otherwise, it may be dangerous in the long run, especially for some patients with chronic kidney disease, it is best to consult a doctor for advice.
Children from 1 to 10 years old should not exceed 50 micrograms per day.
Infants under 12 months cannot exceed 25 micrograms per day
Adults should not exceed 100 micrograms per day, and the recommended amount is 10 micrograms per day. This includes pregnant women and breastfeeding women. However, dark-skinned pregnant women and women with high-risk pregnancy may require higher doses.
But if your doctor asks you to take a higher dose of vitamin D, you should follow your doctor’s advice.
Department of Public Health England (PHE) also suggested that some people year-round service vitamin D, especially if you:
live in nursing homes
or for religious reasons always cover most of the body when the skin to go
What effect does diet have on vitamin D?
Vitamin D supplements are easily available and are sold in many supermarkets and pharmacies. Usually most vitamin D supplements are vitamin D3, which is the part of the vitamin synthesized through the skin and sun. Vitamin D2 can be obtained from some plant foods.
Although a balanced diet can ensure the normal functioning of the human immune system, there is no single nutrient, food or supplement that can greatly improve your immunity.
And vitamin D is difficult to completely rely on diet to supplement, in other words, diet is not enough to meet the vitamin D needs of the body.
But this does not mean that you do not need to eat a balanced diet, because it is beneficial to maintaining your good health.
These healthy foods include vitamin D-rich fish and eggs, some vitamin D-fortified breakfast cereals, yogurt, and margarine.
How about getting more sun?
Since sunbathing helps increase vitamin D, is it better to sunbathe more?
Although sun exposure is indeed good for increasing vitamin D, the sun can also burn the skin and even cause skin cancer. Therefore, the overall health needs to be considered, and it must be safe and not excessive.
At the same time, pay attention to applying sunscreen when basking in the sun to protect yourself.
