While the efficiency varies considerably among individuals, studies suggest that vitamin D absorption from supplements in healthy people can range from 55% to 99%. The amount of a vitamin D supplement that is actually absorbed is influenced by a number of factors, including the supplement's formulation, dietary habits, and individual health status.
