VITAMIN FIX
Are we getting enough? Are we getting too much? Vitamin D deficiency is a hot topic in dermatology circles. Dermatologist Ryan De Cruz shines a light.
Is vitamin D deficiency something we need to be concerned about?
“Although some Australians are deficient in vitamin D, it is a problem that is most concerning in children and older Australians. It is important to be aware of optimal vitamin D levels for your age and gender, but it’s not something that you need to be concerned about, unless you are at risk of vitamin D deficiency.”
Other than sunlight, how else can we get it?
“In addition to vitamin D produced following sun exposure, a small amount of vitamin D can be obtained from some foods such as oily fish, eggs and meat, or fortified foods such as margarine and some milks. While some sun exposure is necessary for vitamin D production, it is important to remember that all sun exposure carries a risk of UV damage and skin cancer, especially for people with fair skin. Extended and deliberate sun exposure, without any form of sun protection, is not recommended. When the UV index is above three, a few minutes of mid-morning or mid-afternoon sun exposure to arms and hands, on most days of the week, should be sufficient to maintain adequate vitamin D levels.”
What are some common misconceptions about vitamin D?
“A common misconception surrounding vitamin D is that prolonged sun exposure, including sunbaking, is necessary for vitamin D production. Only a few minutes of sun exposure to a small area is required for sufficient UV radiation to promote vitamin D synthesis. It is also a common misbelief that using sunscreen causes vitamin D deficiency, but it has been proven that regular use of sunscreen has little effect on vitamin D levels.”
