What is vitamin D good for? All of us have heard of vitamin D, but many people still do not know how important this vitamin is. Vitamin D is not a single vitamin – it is a group of vitamins, called fat-soluble secosteroids.
What Is Vitamin D?
Vitamin D is actually a pro-hormone that can be synthesized in the human body during the sun exposure. In fact, sunlight is the best source of vitamin D. Although there are foods that contain this vitamin, sun exposure remains the best way to get vitamin D. It is not recommended to spend time in the sun if it is too strong, but it is highly recommended to expose your skin to the morning sun (or after 5 pm). If you are white-skinned, twenty minutes will be quite enough for your skin to produce vitamin D. If you are dark-skinned, you will need thirty minutes (or more). Dark skin needs more time to synthesize vitamin D, which is why people with dark skin have more chances to become deficient in vitamin D.
