Vitamin D: The sunshine vitamin

Although vitamin D is produced naturally by the body on exposure to sunlight, during autumn and winter the sun's UV rays aren't strong enough for the process to occur. For this reason, Public Health England recommends taking a vitamin D supplement every day once summer is over. This so-called sunshine vitamin is vital for maintaining healthy bones, teeth and muscles. Watch the short video below or read on to see the ways vitamin D can support your health.

Public Health England recommends that everyone over the age of one year should take a daily supplement providing 10mcg vitamin D during autumn and winter. This is very much a minimum to prevent deficiency diseases

In the European Journal of Clinical Nutrition5, research found that not only are low vitamin D levels common in people with IBS, but there is also a link between symptoms and vitamin D levels. The higher a person’s vitamin D levels, the research suggested, the less likely they were to experience severe IBS symptoms.
