What it does: Vitamin K2 helps ensure that calcium is deposited in bones and teeth rather than in blood vessels, which supports bone strength and arterial flexibility.
How it is used: It is commonly found in supplements aimed at bone health, cardiovascular support, and maintaining healthy calcium distribution, often paired with vitamin D or calcium.
Natural sources and supplement forms: Vitamin K2 is naturally present in fermented foods like natto and certain cheeses, as well as small amounts in animal products. Supplement forms mainly include MK-4 and MK-7, with MK-7 offering a longer half-life in the body.
Why it appears in supplement formulas: Brands add Vitamin K2 to help support strong bones and clear arteries by optimizing where calcium is used in the body, especially in formulas with other bone-supporting nutrients.
What to know before use: If you are taking blood-thinning medications, consult a healthcare provider before using Vitamin K2, as it can influence blood clotting function.
