                                According to a 2014 study, consuming vitamin D with a high-fat meal can increase blood levels by over 30% compared to a fat-free meal. The best time to take vitamin D3 K2 largely depends on your personal routine and whether taking it in the evening affects your sleep, though taking it with a meal containing fat is the most critical factor for absorption.
