Scientific research has proven that having low vitamin D levels in the blood causes cognitive impairment. However, more studies are essential to determine the benefits of vitamin D supplementation in this regard.

Now, it is clear that due to its anti-inflammatory, antioxidant, and neuroprotective properties, calciferol helps brain cell activity.

Prevents Rickets in Children

This rare condition develops in vitamin D deficiency children because they don’t get enough calcium from their diet, causing their bones to become soft and bend. However, vitamin D supplements can stop or treat this problem if it already exists.

Involved in Important Body Processes

Calciferol regulates the levels of calcium and phosphorus in the blood and, at the same time, promotes the intestinal absorption of these from food and the reabsorption of calcium in the kidneys.

In another order of concepts, this vit is also complex in the immune system and muscle function processes.

Researchers stay to study the link between vit D deficiency and various medical conditions such as diabetes, breast, colon, prostate, and ovarian cancer, chronic fatigue, psoriasis, rheumatoid arthritis, and immune or mental illnesses.

Medications for psoriasis. Some drugs, such as calcipotriene (Dovonex, Sorilux), in combination with vitamin D, can increase the risk of too much calcium in the blood.
