– What is Vitamin D 3?
Vitamin D belongs to the family of fat-soluble vitamins, which include vitamins A, D, E and K. These vitamins are absorbed well with fat and are stored in the liver and fatty tissues.
There are two main forms of vitamin D in the diet:
Vitamin D2 (ergocalciferol): Found in plant foods like mushrooms.
Vitamin D3 (cholecalciferol): The flesh of fatty 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.
Natural sources of vitamin D are limited, especially if you’re vegetarian or don’t like fish.
Foods such as cow’s milk, soy milk, orange juice, cereals, and oatmeal are sometimes fortified with vitamin D.
However, sunlight is the best natural source of vitamin D3. The UV rays from sunlight convert cholesterol in your skin into vitamin D3
