The vitamin D is a dietary supplement of high consumption in Puerto Rico. The two physiologically important forms of vitamin D are ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). These two forms are transformed in the body to become calcitriol (the active form). Vitamin D is fat soluble, which means it is fat soluble and your body can store it for a long time.
Vitamin D promotes the absorption of calcium in the intestine and is necessary for the growth and renewal of bones. On the other hand, it is essential for the modulation of cell development, neuromuscular and immune function and the reduction of inflammation. The vitamin D supplement can be found in several forms, such as: capsules, tablets, among others.
On the other hand, vitamin D can also be obtained through foods, such as: salmon, herring, sardines, canned tuna, shrimp, egg yolk, mushrooms, fortified foods (cow’s milk, soymilk, Chinese juice, cereal and oatmeal), among others.
With an exposure of approximately 15 minutes during 10:00 am to 3:00 pm, an adequate amount of vitamin D can be obtained depending on the factors mentioned above. It should be mentioned that it is always important to protect yourself from excessive sun exposure, due to the risks of burns or others.
