Vitamin D3, otherwise known as cholecalciferol, is a pro-hormone and fat-soluble nutrient produced in the skin. It is a seco-steroid hormone that regulates calcium homeostasis and balance within the body. It is an essential vitamin and one of 24 critical micronutrients the body needs to survive.
Vitamin D is known as the "sunshine vitamin" because the skin can produce it photochemically from sunlight or ultraviolet light. Vitamin D formed in this manner is called "natural vitamin D" or vitamin D3. Sun exposure for just 15 minutes daily can provide 2,000 to 5,000 IU of vitamin D. Individuals are at a greater risk of vitamin D3 deficiency during the winter, as they tend to spend more time indoors. They’re likely only exposing their hands and face to sunlight as well, which dramatically reduces the body’s ability to produce vitamin D from sunlight. Wearing sunscreen also inhibits vitamin D3 absorption.
