Low mood and back pain are signs of a vitamin deficiency that could cause rickets in kids.
The body needs vitamins to work properly and stay healthy. Most people get all the nutrients they need through a varied and balance diet, according to the NHS, but in the case of vitamin D, our bodies create it from direct sunlight on the skin outside.
Vitamin D helps regulate the amount of calcium and phosphate in the body, nutrient which keep bones, teeth and muscles healthy. The problem is, the UK gets such little sunlight in autumn and winter, there's only a period of roughly six months from late March to September when the sun is strong enough for most people to get the vitamin D they need.
