Important for regulating the amount of calcium and phosphate in the body to keep bones, teeth and muscles healthy, Vitamin D is an important part of your everyday diet. A lack of Vitamin D can lead to immune system disorders, infections, brittle bones and bone pain [1].

Let’s discuss Vitamin D further and answer the question: What are the symptoms of low Vitamin D levels?

What are the symptoms of low Vitamin D levels?

If you’re living in an area of the world that doesn’t get much sun, it’s likely that you don’t get enough vitamin D [2]. The good news? When the sun does begin to shine, you should be able to get all the vitamin D you need from sunlight - just another excuse to get out into the fresh air! [3]

With that said, low Vitamin D levels can be quite common and the majority of the time, you might not even experience any symptoms. Though, if you do, they can include:

  • Getting sick often
  • Fatigue
  • Bone pain
  • Muscle pain
  • Hair loss

How much Vitamin D do I need?

The Recommended Dietary Allowance for adults is 600 international units (IU) of Vitamin D a day. This rises to 800 IU a day for those over the age of 70 [4].

It’s important to remember that too much Vitamin D, just like too little, can cause health problems. So, be careful not to overdo it!

What are good sources of Vitamin D?

As your body creates Vitamin D from direct sunlight, once the sun makes a much anticipated appearance, you should be able to get all the Vitamin D you need [5].

While you await the spring and summer sun, you can find Vitamin D in a number of foods, these include:

  • Oily fish
  • Red meat
  • Liver
  • Egg yolks
  • Fortified foods

It’s important to keep an eye on your vitamin levels and monitor them regularly. This can be done by visiting your local doctor or taking a vitamin test from the comfort of your own home.
