                                Over 222,000 participants were analyzed in a 2019 meta-analysis that found increased dietary intake of vitamin K1 or K2 was linked with a moderately reduced risk of coronary heart disease. However, a key question for many supplement users is whether it is better to take vitamin K2 at night or day to maximize its benefits.
