What is vitamin D3?

Vitamin D3 is a fat-soluble vitamin that is produced in the skin upon exposure to sunlight. It can also be obtained from dietary sources such as fatty fish, eggs, and fortified foods or supplements.

How does it work?

Vitamin D3 plays an essential role in calcium and phosphorus absorption, bone health, immune system function, and regulation of cell growth and differentiation. It is also believed to have anti-inflammatory and antioxidant effects.

What are the active ingredients that are important for its medicinal properties?

The active ingredient in Vitamin D3 is cholecalciferol, which is produced in the skin from 7-dehydrocholesterol upon exposure to ultraviolet B (UVB) radiation. Cholecalciferol is then converted to calcidiol in the liver and to the active form, calcitriol, in the kidneys.

What forms does it come in?

Vitamin D3 can be obtained from dietary sources such as fatty fish, egg yolks, and fortified foods or supplements in the form of cholecalciferol.

What if there’s an imbalance or deficiency?

Vitamin D deficiency can lead to rickets in children and osteomalacia in adults, as well as increased risk of falls and fractures, muscle weakness, and immune system dysfunction. In severe cases, it can cause seizures and heart failure.

When was it first used for medicinal purposes?

Vitamin D3 was first recognized for its role in preventing rickets in the early 20th century.
