Most of us know vitamin D is vital for strong and healthy bones, helping with calcium absorption in the intestine. However, scientists have found other interesting association between low vitamin D blood serum level and some health conditions,that may even have an impact to your children!
Vitamin D supports a healthy immune system, reduces inflammation and helps with calcium absorption. Gathering information from different research studies, low vitamin D level is a risk factor for osteoporosis, rickets disease in children and osteomalacia in adults, bone fractures in elderly, cancer, depression, intentional self harm and suicide attempt.

Furthermore, vitamin D deficiency has been suggested to favor a poorer outcome of Coronavirus disease-19 (COVID-19).(3) A study from Italy published in 2021 found people admitted to hospital with moderate to severe respiratory symptoms had lower vitamin D in their blood serum compared to people who only have mild symptoms.(3)
Healthy Bones Australia recommends a vitamin D level of at least 50 nmol/L at the end of winter and during summer higher levels are common in the range of 60-70 nmol/L. We can get vitamin D from diet, or through UVB in direct sunlight when skin is exposed. To reach a recommended level of vitamin D, we need an average of 6-8 mins of sunlight daily(in NSW) during summer months and 5 times longer in winter months!(4) It should be noted that glasses blocks out UVB from the sunlight, together with the increase time spent indoor during winter months, vitamin D level can really fluctuate from season to season. In this case, consider consuming cod liver oil, more mushrooms, oily fishes such as salmon and mackerel to ensure vitamin D level is adequate.
