Nonetheless, the NHS says that in summer months, the majority of the population will get enough vitamin D through exposure to sunlight and a healthy, balanced diet.
Around 20 percent of adults may have low vitamin D status, and there are several main risk factors for vitamin D deficiency.
The body creates vitamin D from direct sunlight on the skin when outdoors, so the winter may be a time when vitamin D deficiency is more common.
The NHS says risk factors include a lack of sunlight exposure, darker skin, being housebound, malabsorption, and being pregnant or breastfeeding.
