What is vitamin D3 and its deficiency?

Vitamin D3, also known as cholecalciferol is a fat-soluble, type of vitamin D that is consumable from foods for supplementation in the body. It is also naturally produced in the skin when exposed to sunlight. It is important for absorption of calcium and phosphates from the stomach. It also helps calcium perform its role in the body and implicates positive overall health. Once in the body, D3 manifests itself as a hormone where it circulates distributing calcium and phosphorous from digested foods. D3 deficiency is the low count of the vitamin in the body, thus resulting in its malfunction and cannot carry out its role in the body accordingly.

  • Familial hypophosphatemia: D3 is used in familial hypophosphatemia thus increasing the levels of phosphate in the blood stream.
  • Vitamin D3 can be used in kidney diseases to regulate the levels of calcium and enhance the normal growth of bones.
  • D3 drops are helpful to infants to boost the levels since breast milk contains low volumes of the vitamin. It helps in lowering chances of arterial wall stiffness. On the other hand, low levels of cholecalciferol can lead to atopic childhood and allergic diseases e.g. dermatitis and asthma.
  • Vitamin D3 boosts the immune system thus preventing illnesses such as autoimmune diseases and certain types of cancer by influencing the expression of the cancerous cells and malignant growth. Also, improves brain health and the nervous system.

Vitamin D3 Warnings

As much as vitamin D3 is useful in strengthening bones among other advantages, it is important to consume the right amounts of cholecalciferol. This is because too much of the vitamin can lead to calcification of bones, hardening of kidneys, hurt, blood vessels and lungs. Too much of something can be poisonous, instead of being useful and do more harm to the body. On the other hand, low levels of D3 has been connected to Leukemia (blood cancer), due to low exposure to sunlight.
