Don’t just pop a couple pills in your mouth and think you’re getting the most out of your vitamin D supplements. According to a new Pfizer-funded study published in the Journal of the Academy of Nutrition and Dietetics, eating a meal with fat can actually enhance vitamin D absorption.
“Vitamin D is fat soluble and the absorption process is similar to that of dietary fats,” the study’s lead author Dr. Bess Dawson-Hughes, a senior scientist at the USDA Human Nutrition Research Center on Aging at Tufts University told Medical Daily. “Ingestion of fat stimulates the secretion of bile and promotes the formation of micelles, small structures which transport the fat and vitamin D to the gut absorptive surface, thereby promoting their absorption.”
Researchers studied 50 healthy men who were randomly assigned to one of the three meal options along with a vitamin D supplement. One group ate a fat-free meal, the second group ate a low-fat (30 percent of total calories were fat) meal, and the third ate a high-fat meal. Those who ate a meal containing fat absorbed up to 32 percent more of the vitamin D supplement than those who had a fat-free meal. Dawson-Hughes and her team thought the types of monosaturated or polyunsaturdated fats would influence vitamin D absorption, but their results said otherwise.
