Tag: Provitamin d3

Did you know that as many as 50% of people worldwide may have insufficient vitamin D levels? This vital nutrient, crucial for calcium absorption and bone health, is naturally produced in the skin. Understanding what fat is a precursor to vitamin D is key to grasping how this process occurs and how you can optimize your body's production.

An estimated 40% of the worldwide population is vitamin D deficient, which brings attention to its precursor, 7-dehydrocholesterol (7-DHC). 7-dehydrocholesterol, also known as provitamin D3, is primarily found in the deeper layers of mammalian skin, where it is converted into vitamin D3 through exposure to ultraviolet B (UVB) radiation from sunlight. It is a critical component of the cholesterol synthesis pathway and is also present in certain animal products and industrial sources.
