The British winter is just around the corner. Anyone living in England, Wales, Scotland, and Northern Ireland are well aware of the severity of the winter season in Great Britain. The next couple of months will bring common winter illnesses such as colds, coughs, pneumonia and influenza.

Our immune system plays a crucial role in fighting off the winter bugs and keeping us well. However, with ageing, our immune system becomes weaker, and we need proper nutrition to stay healthy.

medino has worked with Hashmats Health to explain the importance of Vitamin D and the benefits it may have on your immune system.

Why Vitamin D is important

Vitamin D is an essential nutrient that is produced in the skin from the body’s exposure to sunlight. The amount of sunlight varies from person to person and whether one has darker skin, but it is suggested that a minimum of 15 minutes can produce vitamin D. If you're taking Vitamin D supplements due to a deficiency, it can take 2-3 months of consistent intake to increase Vitamin D blood levels.

According to various surveys, every 1 in 5 people in the UK has low vitamin D levels. The problem increases during the winters due to less exposure to sunlight. A deficiency of vitamin D may increase the susceptibility to infections and autoimmune diseases.

Since the Covid-19 pandemic, there has been considerable interest in researching vitamin D. An article published in the Irish Medical Journal showed that people with low vitamin D levels have a higher risk of acute respiratory tract infection and community-acquired pneumonia. This suggests that vitamin D supplementation may enhance resistance to Covid-19 infections or limit its immunological damage.

Foods and dietary supplements have two main types of vitamin D: vitamin D2 (ergocalciferol) and D3 cholecalciferol).
