There are two kinds of natural vitamin D, namely vitamin D2 and vitamin D3. The body produces about 200 to 400 ius of vitamin D3 daily. Vitamins D2 and D3 present in food are absorbed by the gut. When the ultraviolet rays of the sun hit the skin, the 7-dehydrocholesterol in the skin can be converted into vitamin D3. We get most of our daily vitamin D needs from sunlight, except for a small portion of our food supply. So what does vitamin D do? What does vitamin d3 do?

Is the action of vitamin d what action does vitamin d3 have

Vitamin d is powerful

Experts have analyzed the effects of vitamin D:

Heart disease Vitamin D reduces insulin tolerance, which is a major factor in heart disease.

Lung tissue undergoes repair and change throughout a person's life, and since vitamins affect the growth of many types of cells, they may play a role in the repair process.

Cancer, including breast, colon, ovarian and prostate cancers, is thought to play a key role in regulating cell division, a regulatory mechanism that is lacking in cancer patients. So, by preventing cells from overmultiplying, vitamin D protects against certain cancers.

Diabetes In type I diabetes, the immune system kills the body's own cells. Scientists believe that vitamin D acts as an immunosuppressant. They think it may prevent the immune system from overreacting.

Hypertensive vitamin D is used by the accessory thyroid gland in the neck. These glands secrete a hormone that regulates calcium levels in the body. Calcium helps regulate blood pressure. But scientists don't fully understand the process.

The risk of developing schizophrenia may be linked to exposure to sunlight in the months before birth. Lack of sunlight may lead to vitamin D deficiency. Scientists believe this could affect the development of the foetal brain.

Rickets and Osteoporosis Vitamin D strengthens bones and prevents rickets in children and osteoporosis in old age.

Vitamin D deficiency in MS limits the body's production of 1, 25-dihydroxyvitamin D3, a hormonal form of vitamin D3 that regulates the immune system. Its deficiency may increase the risk of developing multiple sclerosis.

The role of vitamin D3:

Vitamin D3 plays an important role in the mineralization of bone tissue in vivo.

1. Improve the absorption of calcium and phosphorus in the body, so that the plasma levels of calcium and phosphorus reach the saturation degree.

2, promote growth and bone calcification, promote dental health;

3, increase phosphorus absorption through the intestinal wall, and increase phosphorus reabsorption through the renal tubules;

4. Maintain the normal level of citrate in the blood;

5, prevent amino acid loss through the kidney.

But vitamin D3 does not act directly, and must first be converted into its active form, 1, 25-dihydroxyvitamin D3, to have any physiological effect.

Active vitamin D3 promotes calcium absorption in the small intestine, reduces increased PARathyroid hormone concentration, promotes osteogenesis and alleviates pain.
