Vitamin D is a crucial nutrient that supports various bodily functions, including bone health, immune system regulation, and cell growth. Measuring vitamin D levels can be essential for assessing an individual’s vitamin D status and determining whether supplementation or dietary modifications are necessary.
Checking vitamin D levels involves a simple blood test that measures the amount of 25-hydroxyvitamin D (25(OH)D) in the blood. 25(OH)D is the primary circulating form of vitamin D and is used as an indicator of overall vitamin D status.
