The production of D-3 in the human body is a photochemical reaction that occurs when the skin is exposed to UVB radiation. However, the catalytic effect of sunlight varies. Modern lifestyles, prolonged use of photoprotective products and environmental factors contribute to the widespread occurrence of vitamin D-3 deficiency, which affects approximately 50% of the world's population across all ethnicities and ages.

Vitamin D-3 plays a significant role in the development and maintenance of bones and bone density. It promotes adequate calcium absorption, which also contributes to healthy bones and teeth. In addition, it participates in healthy cell growth and the maintenance of a normal nervous and immune system.

D-3 is found in a few foods, mostly animal products, such as salmon, tuna, sardines, mushrooms, "fortified" milk, and egg yolks. For those who have difficulty reaching recommended levels, taking a vitamin D-3 supplement (with the approval of a doctor) can help boost D-3 levels in the body.
