Almost all glass blocks ultraviolet (UV) radiation. As a result, you will not be able to increase your vitamin D levels by sitting in front of a sunny window.
What vitamins do you get from the sun?
You can get Vitamin D from the sun, but it is best to take supplements. You can also get it from fish oil and cod liver oil. TIP: Top up your Vitamin D levels by going outside for a few minutes in the morning before you go into work, especially if you spend most of the day inside.
