Vitamin D is an essential nutrient for one’s health and well being. It’s a bunch of fat-soluble secosteroids which helps the body enhancing intestinal absorption of calcium and phosphate. Like other vitamins or minerals, we get vitamin D only from dairy products and no other source. So mostly its either prepared by our body or when we expose to sunlight. Hence, sunlight is the direct source of vitamin d and that’s why it’s called Sunshine Vitamin.
Vitamin D is of two types:
1. D2 – known as Ergocalciferol which we get from fortified foods, plant foods, and supplements.
2. D3 – known as Cholecalciferol, we get again from fortified foods, non-veg sources like fish, eggs, liver. Internally produced when our body is exposed to sunlight.
How Much Body Gets The Vitamin D from Sunlight?
The UV rays in the sunlight are responsible for converting Cholesterol in our skin into Vitamin D. All you need to do is to sit under the sun before 9 am in the morning as our skin needs are some exposure to sunlight.
Deficiencies In Vitamin D:
It’s been estimated that in the world around 1 billion people are deficient of Vitamin D in their blood. A person with dark skin or a person who is obese or overweight tends to be deficient of Vitamin D. You can get the Vitamin D test done very easily, its just that you need to go for a blood test.
