Question

Why do we obtain vitamin d only during dawn and dusk?

Answer 1

It is not true that we obtain vitamin D only during dawn and dusk.  We obtain vitamin D from the sunlight which means that we can obtain it anytime that the sun is shining.  Of course, it is wise to consider the harmful effects of the sun's UV rays.  These rays are at their minimum at dawn and dusk,.  So that is a good time to get vitamin D while lowering the amount of UV exposure.

Food sources:

Very few foods in nature contain vitamin D. The flesh of fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Small amounts of vitamin D are found in beef, liver, cheese, and egg yolks. Vitamin D in these foods is primarily in the form of vitamin D3 (cholecalciferol) and its metabolite 25(OH)D3. Some mushrooms provide vitamin D2 (ergocalciferol) in variable amounts.
