Vitamin D

Introduction

Vitamin D is a fat-soluble vitamin essential for maintaining strong bones and overall health. It helps the body absorb calcium and phosphorus, which are vital for bone mineralization. Vitamin D is naturally produced in the skin upon sunlight exposure and can also be obtained through certain foods or supplements. Deficiency of Vitamin D can lead to bone disorders like rickets in children and osteomalacia or osteoporosis in adults. It also plays a role in boosting the immune system, supporting muscle function, and reducing inflammation in the body.
