The role of Vitamin D in your body

Posted on June 13, 2018

Unlike most vitamins, vitamin D acts more like a hormone than a vitamin in your body. Every cell in your body has a receptor for it, including the immune cells. Vitamin D acts to regulate the calcium and phosphate levels in the body, so it’s important for helping keep your bones, teeth and muscles healthy. Vitamin D deficiency is very common, but the symptoms can sometimes be hard to spot.

Who can be affected by Vitamin D deficiency?

It’s estimated that about 1 billion people around the world have low levels of the vitamin in their blood. And according to the National Institute for Healthcare and Excellence, around 1 in 5 adults and 1 in 6 children in the UK could be deficient.

In many cases, vitamin D deficiency won’t show any obvious symptoms.

Vitamin D deficiency symptoms may include:

  • Aching bones or back pain. Too little vitamin D in your body can lead to weakness of the bones and development of conditions like misshapen bones (osteomalacia) and soft bones (rickets)
  • Muscles weakness. Poor muscle strength and weakness may be associated with vitamin D deficiency, especially in older people
  • Low mood or depression. Lower levels of vitamin D have been linked to the serotonin level in the brain
  • Weight gain. Although consuming more vitamin D won’t necessarily make you lose weight, those with low vitamin d levels may be prone to gaining weight
  • Persistent coughs and colds. Vitamin D helps keep your immune system strong so you’re able to fight viruses that cause illness
  • Fatigue. Studies have found that vitamin D deficiency is fairly common in those who report feeling tired a lot of the time

How to combat Vitamin D deficiency

Your body makes the majority of its vitamin D from cholesterol when your skin is exposed to sunlight. So although vitamin D can be difficult to get in the right amounts from diet alone, there are certain foods which are a good source of the vitamin.

Foods high in Vitamin D include:

  • Fatty, oily fish like salmon, sardines, mackerel and fresh tuna
  • Egg yolks
  • Liver
  • Red meat
  • Fortified foods, i.e. foods that have had vitamins or minerals added that weren’t originally in the food. These may include certain spreads, for example margarine, and breakfast cereals
