The primary role of Vitamin D in metabolism is to maintain the balance of calcium and phosphorus in the body by optimizing their absorption. While calcium absorption is at 10-15% in the absence of Vitamin D, it can increase to 30-80% when Vitamin D is present in sufficient amounts.
Additionally, other important roles of Vitamin D include:
* Reducing calcium loss in the kidneys.
* Supporting bone health and strength.
* Having positive effects on insulin production.
* Numerous scientific studies suggest that adequate Vitamin D levels may play a protective role against various types of cancer.
