In the cold season, many people start thinking about strengthening their immunity. Health experts usually recommend boosting immune function with a balanced diet and exercise. However, according to the chief infectious disease specialist of the United States, Anthony Fauci, there are two vitamins that should be taken in the form of supplements.

The doctor admitted that he himself takes them every day. We are talking about vitamins C and D. “If you are deficient in vitamin D, it will greatly affect your susceptibility to infection. I would recommend taking vitamin supplements, as I do myself,” Fauci said.

As for vitamin C, it is a good antioxidant, the expert added. “So if someone wants to take it extra, about a gram a day will be enough,” he advised.

What does the science say?

Fauci noted , that scientists have proven the danger of vitamin D deficiency for health. In particular, it was found that with its low level, the body becomes more vulnerable to virus infection.

For example, a review of studies involving 11,321 people found that those who took daily or weekly vitamin D supplements were less likely to develop respiratory tract infections than those who did not. In addition, laboratory studies have shown that vitamin D can inhibit the growth of cancer cells and reduce inflammation, said the Harvard School of Public Health. The substance also helps the body absorb calcium, which protects bone health.

How much vitamin D should you take

According to the US National Institutes of Health, adults under the age of 70 should get 600 IU of vitamin D daily. People over 71 should receive 800 IU. The upper limit of the daily dose is 4,000 IU.

Other Ways to Boost Your Immune System

In addition to taking vitamin D supplements, Dr. Fauci recommends three other ways to boost your immune system: p>

• Sleep at least seven hours a day.
• Follow a balanced diet, adding more vegetables, fruits, lean protein and nuts to the diet.
• Try to avoid stress , which also negatively affects the immune system.
