Vitamin K is best known for its role in normal blood clotting, and it's also involved in activating certain proteins related to bone mineralization.
K1 is found mainly in leafy greens, while K2 (including MK-4 and MK-7) is found more in fermented foods and animal products. The two forms are generally studied in relation to different aspects of vitamin K's role in the body, though both belong to the same vitamin family.
Some vitamin K supplements contain K1 or K2 alone, while others combine both forms or pair K2 with vitamin D3. Review the Supplement Facts panel to see which forms are included in a specific product.
Vitamin K supplements are commonly available as K2 in MK-7 or MK-4 form, in softgels, capsules, and combination formulas with vitamin D3.
Vitamin K supplements come in different forms, strengths and formats. Comparing the Supplement Facts panel and ingredient list can help you choose a product that meets your preferences.
