Vitamin D5

Vitamin D5, also known as Sitocalciferol, is a form of Vitamin D. It is one of the five known types of vitamin D, which also include Vitamin D1, Vitamin D2, Vitamin D3, and Vitamin D4.

Chemical Structure

Vitamin D5 has a similar chemical structure to other forms of vitamin D. It is a secosteroid, which means it is a steroid with one of its rings broken. The specific structure of vitamin D5 includes a side chain with seven carbon atoms, distinguishing it from other forms of vitamin D.

Sources

Vitamin D5 can be found in certain types of fish and mushrooms. It can also be synthesized in the laboratory.

Functions

Like other forms of vitamin D, Vitamin D5 plays a crucial role in maintaining bone health by aiding in the absorption of calcium and phosphorus in the body. It also supports immune system function and may have roles in regulating cell growth and differentiation.

Deficiency

A deficiency in Vitamin D5 can lead to a number of health problems, including rickets in children and osteomalacia in adults, both of which are characterized by soft, weak bones. Other potential effects of deficiency include increased risk of cardiovascular disease, certain types of cancer, and autoimmune diseases.

Supplementation

Vitamin D5 is available as a dietary supplement, often in combination with other forms of vitamin D. Supplementation may be recommended for individuals who have difficulty obtaining sufficient vitamin D from their diet or sunlight exposure.

Safety

While Vitamin D5 is generally considered safe, excessive intake can lead to vitamin D toxicity, characterized by nausea, vomiting, poor appetite, constipation, weakness, and weight loss. More seriously, it can also raise blood levels of calcium, causing mental confusion and heart rhythm abnormalities.
