Vitamin D Test

Vitamin D, a nutrient and hormone produced by the skin in response to sunlight, is crucial for bone health by regulating calcium and phosphorus. It also supports nerve, muscle, immune systems, and mental health. The vitamin D blood test measures 25-hydroxyvitamin D (25-D), indicating stored vitamin D levels. Deficiency can cause fatigue, bone pain, and depression.
Vitamin D helps your body absorb calcium, essential for strong bones, and regulates various cellular functions. Its anti-inflammatory, antioxidant, and neuroprotective properties support immune health, muscle function, and brain activity. Sources include fortified foods and fatty fish, with production also stimulated by sunlight.
Factors like time of day, season, latitude, and skin pigmentation affect vitamin D production. Older adults often lack sun exposure and have absorption issues. A blood test can check vitamin D levels, and taking a multivitamin may help. The recommended daily intake varies: 400 IU for infants, 600 IU for ages 1-70, and 800 IU for those over 70.
