Glossary Vitamin D Deficiency

lack of sufficient vitamin D in the body

Vitamin D deficiency, also known as hypovitaminosis D, occurs when the body doesn't have enough vitamin D, which is crucial for maintaining healthy bones and supporting the immune system. This deficiency can lead to conditions such as rickets in children and osteomalacia or osteoporosis in adults, and it may also contribute to hair loss and other health issues.
