Vitamin D deficiency: The three warning signs that you are lacking the vitamin

Vitamin D works with calcium and phosphorus for healthy bones, muscles and teeth. The body makes vitamin D under the skin when a person is outside in the daylight, which is the reason why vitamin D is known as ‘the sunshine vitamin’. Vitamin D absorbs calcium and blocks the release of parathyroid hormone and also plays a role in muscle function and the helps the immune system. The body gives a person signs that it is lacking in vitamin D. What are the three warning signs?

Fatigue and tiredness

If a person constantly feels tired it may mean they are vitamin D deficient.

Studies have shown that very low blood levels cause fatigue and can impact a person’s life negatively. Experts recommend taking a vitamin D supplement to increase energy levels.


The role of vitamin D in reducing the risk of infections such as pneumonia, bacteremia, urinary tract infections and surgical site infections.

When adequate levels of vitamin D are maintained it lessens the length and severity of upper respiratory infections.

Inflammatory bowel disease

When there is an inability to properly absorb nutrients in the GI tract, there is a higher risk for nutritional deficiencies.

In a 2016 study by US National Library of Medicine National Institutes of Health looked at vitamin D and inflammatory bowel disease and found that a lack of the vitamin increased the risk of the bowel disease and Crohn’s disease.

Foods with the best source of vitamin D include:

  • Oily fish such as salmon, sardines, pilchards, trout, herring, kippers and eel.
  • Cod liver oil
  • Egg yolk, meat and milk
  • Margarine, breakfast cereals and some yogurts

Vitamin D deficiency is the most common and easiest indicator of your health you need to be familiar with

Nutritionist Doctor Steven Lin

Nutritionist Doctor Steven Lin said: “Vitamin D deficiency is the most common and easiest indicator of your health you need to be familiar with.

“Since it’s pretty difficult to take too much vitamin D, I would say it’s safe to assume you could probably use a little more vitamin D in your life.

“I can’t stress this enough: vitamin D is vital to both your dental health and overall health because vitamin D is such an integral party of the immune system and some of the first symptoms of low vitamin D levels are overall malaise and getting sick easily.”

Vitamin D is deficiency is very common and most people who are deficient are unaware. Fortunately, a vitamin D deficiency is usually easy to fix and a person can either increase their sun exposure or eat more vitamin D rich foods.
