Synergy
What is happening. K2 (MK-7) is fat-soluble and absorption increases with dietary fat. Fish oil provides an excellent fat vehicle.
Mechanism. MK-7 is a fat-soluble isoprenoid. Dietary fat stimulates bile secretion and forms micelles that solubilize MK-7 for intestinal absorption via chylomicron incorporation.
Recommendation. Take K2 with fish oil triple strength or a fat-containing meal for optimal absorption.
