Does High-fiber foods Affect Vitamin K2?
May affect absorption or how you feel
The short answer
As a fat-soluble vitamin, K2 absorption depends on fat digestion. High fiber impairs fat absorption and reduces K2 uptake.
How to arrange timing
Take vitamin K2 with a fat-containing meal away from high-fiber foods.
