Wholesale Cholecalciferol Bulk Vitamin D3 Powder
Products Description
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.

Benefits
- Calcium Absorption Regulation: Vitamin D3 plays a crucial role in promoting the absorption of calcium in the small intestine. It helps increase the uptake of calcium from the diet, which is essential for maintaining normal blood calcium levels and ensuring the proper mineralization of bones and teeth.
- Bone Health Maintenance: By facilitating calcium absorption, vitamin D3 contributes to the growth, development, and maintenance of healthy bones. It helps prevent conditions such as rickets in children and osteoporosis in adults.
- Immune System Support: Emerging research suggests that vitamin D3 may also play a role in modulating the immune system. It may help the body defend against infections and support overall immune function.
Application
- Nutritional Supplements: Vitamin D3 powder is often used in nutritional supplements to help meet daily vitamin D needs.
- Food additive: Used as a nutritional enhancer in certain foods to increase the content of vitamin D.
- Medical: Used to treat vitamin D deficiency and related diseases.
