Vitamin D3, known scientifically as cholecalciferol, is a vitamin D formula that is synthesized in the body, after the skin has been exposed to ultraviolet light, and has many benefits to the body.

What is the function of vitamin D3 in the body
Vitamin D3 simply forms a protein that binds with the calcium found in the digestive tract, making calcium absorbable into the bloodstream and thus reaching the tissues that need calcium.

Vitamin D3 balances calcium and phosphorus in the blood. In addition to its role in promoting one of the important functions of the kidneys is the reabsorption of calcium and phosphorus into the blood as much as the body needs, which makes him an important role in the process of building bones and teeth.

Vitamin D3 also adversely affects the thyroid gland, preventing calcium from leaving the bones and returning to the blood when the body does not need it.

What are the sources of vitamin D3?
There are a number of sources of vitamin D3, but the most important is to expose your skin to the ultraviolet rays of the sun to make the vitamin inside the body. The consensus is that the best times to expose your body to the sun is before 10 am or after 3 pm. Exposing the face, limbs, shoulders and back to the sun for 10 to 30 minutes at a time for several days a week is enough to convert the cholesterol in the skin into vitamin D3. Even on cloudy days, 50% of UV rays can reach the skin. But sunscreens prevent them from reaching the skin according to their strengths.

Perhaps it must be mentioned here that the glass does not allow ultraviolet rays to pass through it, so the exposure to sunlight from behind the glass does not benefit.

It is also known that people with dark skin do not benefit greatly from sunlight when exposed to it, as the pigment melanin in the skin in higher quantities than others may not allow to benefit from the rays effectively.

Foods rich in vitamin D3 are generally fatty foods, since vitamin D3 is a fat-soluble vitamin. The most important are:

Whale liver oil, where a teaspoon contains 1,360 IU.
Fatty fish such as salmon and tuna, which contain approximately 150-400 units per meal.
A glass of vitamin-fortified milk, containing approximately 120 units.
Liver and red meat containing about 40 units.
One egg contains about 40 units.
A glass of orange juice contains approximately 130 units.
Most physicians in the Arab world have noticed that the vast majority of people who have been analyzed for vitamin D3, the results were less than 30 ng / mg, most likely due to insufficient sun exposure. Thus, they are provided with vitamin supplements in proportion to the results of the analysis.
