How does vitamin d act on the kidneys?

The vitamin D endocrine system plays a key role in controlling renal excretion of calcium and phosphorus. Why is vitamin D related to the kidney? The kidneys are an important part of helping the body use vitamin D. Vitamin D comes from two sources in people. This could be exposure to ultraviolet B radiation from the sun.

Or, it is absorbed from food or dietary supplements. The kidneys play an important role in making vitamin D useful to the body. Your kidneys convert vitamin D from supplements or from the sun into the active form of vitamin D your body needs. In the case of chronic kidney disease, low levels of vitamin D, sometimes even very low levels, can be detected.

This can happen because injured kidneys are less able to convert vitamin D to its active form. More and more information points to the importance of vitamin D for the body, especially for bone strength.

In addition

to keeping bones healthy, more recent research shows that vitamin D may also protect against heart disease. In fact, people with the lowest levels of vitamin D had a 40% higher risk of cardiovascular disease in one study.

Remember that there are different types of vitamin D, so you shouldn't start taking a supplement on your own. Vitamin D deficiencies have been reported in all types of people, but especially in older people, people with darker skin color (African Americans), and people with a higher body mass index (obesity). According to the most recent information from the Centers for Disease Control and Prevention, more than half of Americans of all ages have low levels of vitamin D.
