What is vitamin D3?

Vitamin D-3 is also known as cholecalciferol; it is manufactured by the human body from sunlight. Vitamin D-3 is essential for healthy bone metabolism, immune modulating and neuromuscular function, explains Vitamin Research Products.

Due to today's primarily indoor living conditions and heavy use of sunscreen, many people are deficient in this essential vitamin. The latest research, according to Vitamin Research products, states that Vitamin D-3 deficiency can be linked to many conditions including cancer, depression, back pain, impaired immunity and macular degeneration. It is imperative pregnant women get enough vitamin D-3, as the deficiency can result in insulin resistance and pre-eclampsia during pregnancy.
