Boosting your own immunity makes sense, and studies show there is lots you can do.

A balanced diet is key, but there are certain nutrients that are particularly important – and scientists have been working hard to find the stars that can help in the Covid battle.

Take these simple steps to strengthen your immune system and keep you well through the tough winter ahead:

Vitamin D, which is essential for healthy bones and muscles, is often known as the sunshine vitamin – giving a big clue as to why we don’t get enough in winter.

While it can be found in some foods, including oily fish, red meat and eggs, our bodies grab the majority of what they need from exposure to sunlight.

One in five Brits is deficient, with the number increasing as the nights draw in.

And that’s why the official advice is to consider taking a supplement containing 10mcg of vitamin D
(the equivalent of 400IU) during winter.

But as well as keeping bones strong, this simple vitamin could also play a key role in the fight against Covid-19.

A super-study published earlier this year, which analysed results from 39 trials, found that taking 10mcg of the sunshine vitamin reduced the risk of respiratory infections by up to 23 per cent.

More recently, researchers at the University of Birmingham, who tested blood samples from 392 healthcare staff, found that 72per cent of those who were deficient in vitamin D had also caught Covid-19.

By contrast, only 51 per cent of those with good levels carried antibodies confirming they had been infected.

Covidence-UK, a study that uses monthly surveys of UK ­citizens to identify potential risk factors for Covid-19, has also ­identified a link.

Researchers are launching a randomized control trial to see if providing free vitamin D to people with low levels reduces their odds of catching the virus. To sign up and support the ­Covidence-UK search for ways to reduce the risk of Covid-19, visit .


Dozens of studies have underlined the importance of zinc for strong ­immunity. And the World Health Organisation confirms it, saying: “Zinc is thought to help decrease ­susceptibility to acute lower ­respiratory tract infections by ­regulating various immune functions.”

Zinc can be found in shellfish, beans and lentils, but eight per cent of adults here in the UK do not get the ­recommended intake.

Research has shown that taking zinc within 24 hours of cold symptoms appearing cuts the duration of ­infections by a third.

Excitingly, studies have confirmed zinc inhibits Covid-19 – and there is evidence it may boost levels of ­interferon, a protein that helps our immune system identify threats.

The balance of good and bad bacteria in our gut has a big impact on ­immunity. Dr Bousquet’s research has also identified a link between fermented dairy products, such as yoghurt and kefir, and a lower rate of deaths from the virus.

A recent Chinese study discovered that probiotic drinks that contained a combination of lactobacillus bacteria reduced the risk of respiratory infections by 59 per cent.

Another study, published in the European Journal of Public Health, found that children who were given daily ­probiotic supplements were around a third less likely to need antibiotics.
