Vitamin D comprises a group of fat-soluble compounds essential for maintaining the mineral balance in the body; the vitamin D form synthesized in humans is called ‘cholecalciferol’ (vitamin D3). Because cholecalciferol is synthesized in the skin by the action of ultraviolet light (UVB), vitamin D doesn’t fit the classical definition of a vitamin - although this doesn’t stop it being recognized as an essential dietary nutrient.
Quali®-D (vitamin D)
The sun is our major vitamin D source. However, several factors reduce the production of vitamin D in the skin, including: Sunscreen with a sun protection factor above eight, age, darker skin pigmentation, northern latitude above 40 degrees and winter. Most vulnerable to low vitamin D status are breast-fed infants, elderly and institutionalized people, obese individuals and African Americans of all ages.
In addition to bone health, emerging science reveals a non-skeletal benefit of vitamin D for several other health outcomes.
A sufficient intake of vitamin D (calciferol) is important as it helps the body to:
- Maintain healthy blood levels of calcium and phosphorus
- Build and maintain healthy bones
- Control cell division and specialization
- Modulate the immune system.
