Vitamin D Deficiency Linked to Fatigue, Body Pain, and Mood Changes

Vitamin D deficiency is increasingly recognized as a common cause of persistent fatigue, hair fall, body pain, and mood changes, especially among women and urban dwellers with limited sunlight exposure. Experts highlight vitamin D's role in calcium absorption, bone health, muscle function, immunity, and reproductive health. Early symptoms often go unnoticed or are mistaken for stress, but timely recognition can prevent complications like osteoporosis and infertility.
