FAQ
Frequently Asked Questions
Vitamin K1 (phylloquinone) is primarily found in plants and is crucial for blood clotting. Vitamin K2 (menaquinone) is found in animal products and fermented foods and is more associated with bone and cardiovascular health.
Dark green leafy vegetables like kale, spinach, collard greens, broccoli, and Brussels sprouts are the richest dietary sources.
Toxicity from dietary vitamin K1 is extremely rare. However, high intake can interfere with blood-thinning medications like warfarin, so consistent intake is advised for those on such drugs.
Vitamin K1 is relatively stable during cooking, though some loss can occur, especially in water. Steaming or sautéing is preferable to boiling to retain more of the vitamin.
