The Vitamin That Helps Keep Calcium Out of Your Arteries ｜ Dr. Mandell

Vitamin K2 has become one of the most talked-about nutrients for supporting healthy aging, strong bones, and cardiovascular health—but what does the science really show? In this video, Dr. Alan Mandell explains how vitamin K2 activates important proteins involved in calcium regulation, helping your body direct calcium to your bones and helping inhibit inappropriate calcium deposits in soft tissues such as your arteries. You'll learn the difference between vitamin K1 and vitamin K2, why vitamin K1 is abundant in leafy green vegetables, and why vitamin K2 is found primarily in fermented foods such as natto, certain aged cheeses, egg yolks, and some animal products. I also explain the two most common supplemental forms of vitamin K2—MK-4 and MK-7—why MK-7 is the form most often chosen for daily supplementation because it remains active in the bloodstream longer, and how to take it for optimal absorption with a meal containing healthy fats. We'll discuss how vitamin D3 and vitamin K2 work together in calcium metabolism, the differences between arterial calcification and cholesterol plaque, who may benefit from increasing K2-rich foods, and when supplementation may be appropriate. Most importantly, you'll learn why no vitamin can replace controlling blood pressure, cholesterol, blood sugar, inflammation, exercise, and a healthy diet when it comes to protecting your heart and blood vessels. I also cover important safety precautions, including why anyone taking warfarin (Coumadin) or other medications should speak with their healthcare professional before starting vitamin K2 supplements. If you've ever wondered whether vitamin K2 can help support healthier arteries and stronger bones, this evidence-based video will help separate scientific facts from myths so you can make informed decisions about your health.
