Vitamin K-2 (MK-4) 100 mcg – 100 Veg Capsules
LifeSource Vitamins Vitamin K-2 (MK-4) delivers 100 mcg of this specific, well-studied form of Vitamin K2 — the same form your body naturally converts other K2 sources into — to support cardiovascular health and proper calcium utilization. Working alongside Vitamin D, K2 helps direct calcium toward your bones and teeth rather than your arteries, supporting both bone strength and healthy arterial function. Just one capsule daily with a meal fits easily into your routine — talk to your doctor first if you're on blood thinners or have upcoming surgery.*
