Vitamin D Sources

Updated: Feb 18, 2021

Deficiency in vitamin D can result from inadequate exposure to sunlight, inefficient production in the skin, not enough vitamin D in your diet, and certain health conditions.

Vitamin D has multiple roles in the body. It assists in:

  • promoting healthy bones and teeth

  • supporting immune, brain, and nervous system health

  • regulating insulin levels and supporting diabetes management

  • supporting lung function and cardiovascular health

  • influencing the expression of genes involved in cancer development

Vitamin D has been getting a lot of attention recently. The UK isn't known for its sunshine during the autumn and winter, therefore a vitamin D supplement could be beneficial during this period. Better still there are good sources of foods rich in vitamin D that can be added to your diet.

🧀 Full-fat dairy products. 

Vitamin D is a fat-soluble nutrient. Full-fat dairy products are one of our richest food sources, if you choose to eat dairy always opt for full fat as skimmed will have it all removed.

🥚 Eggs.

A rich source of Vitamin D at 87iu per 100g. Eat your yolks as this where Vitamin D is found.

🐟 Fatty /oily fish. 

Fatty fish, such as salmon, mackerel, and tuna.


Did you know that mushrooms are one source of vitamin D and that you can naturally multiply their levels by exposing them to sunlight? You can sun dry store-bought or homegrown shiitake, maitake, button, and many other mushroom species. The high vitamin D levels generated will last for more than a year.

☀️ The best way to get the body to produce enough vitamin D is by getting sufficient sunlight and regularly eating a diet that has vitamin D rich food sources. A supplement can help during the winter months to boost your levels if you feel your diet lacks sufficient food sources.
