A member asked:
What is the absorption time of vitamin d3 supplements?
A doctor has provided 1 answer
Very slow: Vitamin d is really a hormone because it is made in skin from the action of sunlight, the main source of our vifamin d. It is absorbed poorly when taken in the form of d3 but is essential for most people in the northern or southern hemisphere because of our limited sun edposure and the use of sun screens when we are exposed to the sun.
