Description
Vitamin D plays a substantial role in the regulation of calcium and maintenance of phosphorus levels in the blood, two factors that are extremely important for maintaining healthy bones. We need vitamin D to absorb calcium in the intestines and to reclaim calcium that would otherwise be excreted through the kidneys.
In humans, the most important compounds in this group are vitamin D3 (Cholecalciferol).
• Helps in the absorption and use of calcium and phosphorus.
• Contributes to normal cell division.
• Contributes to normal blood calcium levels.

THE SUN IS OUR BEST SOURCE OF VITAMIN D
There’s good reason why Vitamin D is called “the sunshine vitamin.” When your skin is exposed to sunlight, it makes Vitamin D from cholesterol. The sun’s ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for Vitamin D synthesis to occur. Vitamin D has many roles in the body and is essential for optimal health. FACTORS THAT MAY DECREASE THE SYNTHESIS OF VITAMIN D FROM THE SUN:
• Living at high altitudes, particular during the winter.
• Excessive use of sunscreen.
• Skin pigmentation (Having a dark skin type).
• Environmental air quality (eg high level of air pollution).
• Weather conditions (eg dense cloud covering).
