Good Fats Research

Healthy Living

An article published in the Journal of the Academy of Nutrition and Dietetics found that taking a vitamin D-3 supplement with a fat-containing meal improved absorption.

In this study, 50 healthy white men and women age 50 and older were randomly assigned to one of three groups: A fat free meal, a meal with a 1:4 ratio of monounsaturated fats to polyunsaturated fats (30% fat), or a meal with a 4:1 ratio of monounsaturated fats to polyunsaturated fats (30% fat). After a 12-hour fast, subjects took a 50,000 IU vitamin D-3 supplement with their assigned meal. Results showed that the taking a vitamin D-3 supplement with a meal that contains fat increased vitamin D-3 absorption by 32%, but the ratio of mono- to polyunsaturated fats did not play a role in absorption rates.
