Physiological conditions and factors such as pregnancy, infancy, menopause, old age, hormones, growth factors associated with calcium metabolism, diseases limiting its absorption, and intestinal microbiota are distinguished among endogenous factors.
What factors increase calcium bioavailability?
Vitamin D3 increases enteral calcium absorption and its reabsorption in the kidneys (similar to PTH). Calcium homeostasis is also controlled by estrogens, corticoids, and thyroxine. What happens to calcium bioavailability during pregnancy? Intestinal calcium absorption normally increases during pregnancy so that the mother can supply sufficient calcium to her fetuses. The maternal skeleton is rapidly resorbed during lactation to provide calcium needed for milk; that lost bone mineral content (BMC) is completely restored after weaning.
