Vitamin D: The Sunshine Nutrient and Who Needs It Most

The liver and kidneys are two vital organs responsible for converting "raw" Vitamin D (obtained from sun or food) into its active, usable form. Individuals with chronic kidney failure or liver disease cannot effectively "activate" the vitamin even if they get enough sun exposure. These patients require specific, pre-processed forms of Vitamin D prescribed by a physician to prevent serious complications such as chronic bone pain and dangerous fluctuations in blood calcium levels.
