Eggs and Vitamin D

Eggs and Vitamin D

Almost a quarter (23%) of Australian adults have a mild or moderate vitamin D deficiency. In the cooler months, these deficiency levels rise to as high as 40%.

Studies have clearly shown that adequate intake of vitamin D is essential for bone development, skeletal health, healthy muscles and teeth and regulating the immune system.

Vitamin D Food Sources v Supplements

A well-balanced diet and sufficient sunlight exposure are generally enough for most people to meet their daily vitamin D requirements. However, for those with vitamin D deficiencies, dietary supplements are often recommended.

It is however, possible to meet the recommended daily intake of vitamin D through a well-balanced diet and sunlight, and deficiencies can be rectified without supplements. 

According to Dietitian Sharon Natoli, where possible, it is best to eat a well-balanced diet, with plenty of vegetables, sufficient amounts of fruit, whole grains, dairy foods or alternatives, healthy fats and protein-rich foods, like eggs, to meet daily nutritional needs.

Do Eggs Have Vitamin D?

Recent research found an average serve of eggs (2 x 60g eggs) contains 8.2µg of vitamin D (82% of your recommended intake of vitamin D), a substantial portion of the recommended dietary vitamin D intake. This highlights that eggs are one of the highest natural sources of vitamin D.

Eggs are also very readily available and a much more affordable option to vitamin D supplements.

Other Vitamin D Food Sources

As long as we are getting sufficient sun exposure, the best source of vitamin D is sunlight.

If you aren't getting enough sun exposure then food sources become even more important. Some foods, such as eggs, provide a lot of vitamin D, while others provide smaller amounts. Some of the top food sources of vitamin D include:


Some milk, soy milks, cheese, yoghurt and breakfast cereals may also be fortified with vitamin D. Dietary choices for many Australians can be a key part to maintaining an adequate vitamin D intake. For meal inspiration to boost your vitamin D, download the recipe book at the bottom of the page. 

Respiratory Infections and the Link to Vitamin D

Evidence from a 2020 systematic review and analysis of 42 trials involving 47,262 participants concluded that vitamin D intake of 10µg - 25µg was effective at reducing acute respiratory infection, including colds and flus1.

Given vitamin D’s role in the immune system, vitamin D has also been investigated for a possible role in preventing or reducing the severity of COVID-19 – also a respiratory infection.

The evidence to date has shown that adequate levels of vitamin D may play a beneficial role in protecting against the development of severe COVID-19 symptoms such as acute respiratory distress, which is the main cause of mortality in individuals with COVID-19. Reducing the incidence of acute respiratory distress will in turn decrease mortality rates from COVID-192.

Having an adequate vitamin D level may not stop individuals from contracting COVID-19, but observational evidence suggests it may decrease the risk or severity of respiratory distress and mortality.

While the evidence is promising, the relationship between vitamin D and COVID-19 is based on preliminary evidence and further investigation is needed to confirm the relationship and the exact role vitamin D is playing.
