Inadequate Vitamin D: What Are The Signs And Symptoms?
6 min read
Many of us grew up drinking a glass of milk with breakfast, lunch and dinner, promised by our parents that its calcium content would help us grow up big and strong.
While it’s true that calcium is important, vitamin D (also known as colecalciferol) also plays a role in supporting your child’s healthy growth and development.
Affectionately known as the ‘sunshine vitamin’ thanks to our bodies’ ability to synthesise it after sun exposure, it’s a fat-soluble vitamin and an essential nutrient.
Our total consumption includes a combination of dietary intake and exposure to ultraviolet light from the sun. In Australia, we get most of our it from sunlight exposure.
It’s essential to help aid your child’s bone development and health, support their healthy neuromuscular function, and maintain healthy immunity .
Helping to control calcium levels in the blood (1), vitamin D aids healthy bone growth and development in infants and children, and supports ongoing bone health.
Maintaining the calcium levels in the blood is also crucial for the healthy function of the nervous system, required for muscle function and nerve conduction.
Your child’s immune system is a dedicated defence mechanism and the first line of defence against bacteria and other germs. Vitamin D plays an important role in supporting your little one’s immune system health.

Sometimes, your child might not be getting enough vitamin D.
There’s not always obvious symptoms, but there are some common risk factors:
While there are some ways you may help to prevent insufficient vitamin D when sunlight is inadequate, if you have concerns about your child’s health, talk to your health care professional.
Mothers who are deficient have been shown to give birth to children with low vitamin D status . Ensuring your levels are adequate during pregnancy may help prevent deficiency in your infant.
Vitamin D is sometimes assumed to be plentiful in a healthy diet but unfortunately, there are very few foods that contain it. Egg yolks and fatty fish such as salmon contain some and other foods including breakfast cereals, types of margarine and spreads may be fortified with it.
It’s been suggested that during summer, Australians with fair skin may be able to achieve adequate levels by spending just a few minutes in the sun on either side of the peak UV times .
As with most health issues, there are a variety of factors to be considered when calculating your child’s sun exposure, including skin type, location and cloud coverage. If you have concerns about your child’s health, visit a healthcare professional.
