The best supplements to take during cold winter months include vitamin D due to the lack of sunshine.
However, a new study has found that topping up on the essential vitamin could also protect against severe asthma attacks too.
Asthma attacks can be more prevalent during winter because cold air in the airways can cause them to go into spasm, according to Asthma UK.
Researchers at Queen Mary University of London discovered that people who took oral vitamin D supplements in addition to standard asthma medication could halve their risk of an asthma attack that required hospital attendance.
“On average, three people in the UK die from asthma attacks every day.
While getting vitamin D from sun exposure is the most efficient way to absorb it, people can struggle to get enough during the winter months and there is also the risk of skin cancer.
