What is Vitamin D?

Vitamin D plays a vital role in development and function, affecting the absorption of other essential nutrients. The body creates vitamin D using ultraviolet rays from sunlight. The rays trigger the vitamin in the skin by reacting with a protein called 7-DHC. 

You need vitamin D for bone health, strengthening your immune system, enabling the gut to effectively absorb calcium and regulating the phosphate in your bloodstream (required for energy, muscles and the nervous system). It also helps cells grow and is crucial for muscle mass and muscle movement.

Who is at Risk of a Vitamin D Deficiency?

  • Pregnant women – The body takes the vitamins absorbed and directs them toward the fetus for development which can leave the mother with a deficiency
  • Children under 5– The younger a child is, the more rapidly they grow and, therefore, can deplete their vitamin D levels faster than older children and adults.
  • pregnant near door

  • People who stay indoors– Considering the body creates vitamin D from sunlight, this can lead to an absence of nutrients.
  • Vegans– Dairy is a significant source of vitamin D. Therefore, vegans are at a higher risk of a deficiency as they do not consume any dairy products.

  • Anyone with darker skin– People with dark skin tones have higher levels of melanin which gives the skin its pigment. The more melanin your body has, the harder it is to absorb and convert vitamin D.
  • Over 65’s – The older a person gets, the more their body slows down in converting and producing vital nutrients. They also tend to spend more time indoors and have a reduced appetite which can affect vitamin D levels.
  • People with excess body weight– When the body carries excess fat, it struggles to function efficiently and produce essential vitamins.
