Product Description:
•    Rapid self-test for the semi-quantitative detection of vitamin D in human whole blood 
•    Vitamin D refers to a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, iron, magnesium, phosphate, and zinc. Vitamin D is produced by skin exposed to ultraviolet B radiation or obtained from dietary sources, including supplements. Average daily vitamin D intake in the population and current dietary reference intake values are often inadequate to maintain optimal vitamin D levels. Virtually every cell in our body has receptors for vitamin D, meaning that they all require a "sufficient" level of vitamin D for adequate functioning.
•    Vitamin deficiency has been linked to various serious diseases: osteoporosis, multiple sclerosis, cardiovascular diseases, pregnancy complications, diabetes, strokes, autoimmune diseases, infectious diseases, etc.
Product Features:
•    The vitamin D test is intended for persons commonly at risk for vitamin D deficiency, such as people who get tired and fatigued easily, have inadequate sun exposure, have limited oral intake, or have impaired intestinal absorption.
