A lot of people are surprised to learn they have a Vitamin D deficiency which, contradictory to common belief, can occur even if you spend a lot of time in the sun. A lot of things can disturb the way you absorb Vitamin D, but boron can improve Vitamin D absorption. Boron helps increase serum levels of calcium, which in turn makes it easier for the body to absorb Vitamin D. In fact, a study conducted at the University of Wisconsin found that Vitamin D rapidly rose in rats who were given boron regularly.
