Sun light and calcium Vitamin D is synthesized in the skin and for this, sun light, i.e ultraviolet rays are needed. It is unlikely to increase the levels of vitamin D by food.


The harmful sun rays are between 11 and 16 o'clock.  Sunbathing between these hours increases the risk of developing skin cancer.


Except these hours, exposing hands, arms and face to the sun for 30 minutes every day would be enough for vitamin D synthesis.  If the whole body can be exposed to the sun, half an hour for 2 days a week would be enough.


Natural sources of vitamin D, except sun light, are oily fish (such as salmon, tuna), fish oil, nettles (urtica), parsley and egg.  Vitamin D medications can be used for vitamin D deficiency, if necessary.
