                                According to scientific research, vitamin D is a fat-soluble vitamin stored in the body's tissues, which is why the duration of its effects can differ significantly based on the delivery method. When addressing the question of how long does vitamin D IV last, the answer isn't a simple timeframe, as it depends on individual factors that influence storage and absorption. Unlike water-soluble vitamins that are quickly metabolized and excreted, the fat-soluble nature of vitamin D allows the body to build up reserves that are released over a prolonged period.
