MK-4 is a short-chain menaquinone naturally occurring in animal-based foods such as liver and egg yolks, but achieving a therapeutic dose through diet alone is difficult. This supplement delivers a concentrated amount that has been investigated in clinical research for its role in bone health.\u003c\/p\u003e\u003cp\u003eVitamin K2 activates proteins that regulate calcium deposition, helping to direct calcium towards bones and away from soft tissues. This makes it important for maintaining both bone density and arterial health.\u003c\/p\u003e\u003ch2\u003eHow Much Vitamin K2 Should You Take?\u003c\/h2\u003e\u003cp\u003eThe dosage in Mega Vitamin K2 is based on clinical evidence. 45 mg (45,000 mcg) of MK-4 per day is an amount that has been shown to support bone health effectively. This is considerably higher than typical dietary intakes, which average around 10–100 mcg per day. For context, the UK reference nutrient intake (RNI) for vitamin K is approximately 1 µg per kg of body weight for total vitamin K (including K1). Higher doses of MK-4 are well tolerated and have been used in studies for bone support.\u003c\/p\u003e\u003cp\u003eLife Extension recommends taking one capsule daily with food for best absorption, as vitamin K is fat-soluble.\u003c\/p\u003e\u003ch2\u003eKey Benefits of Vitamin K2 for Bone Health\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports osteoblast activity:\u003c\/strong\u003e Vitamin K2 encourages osteoblasts — the cells responsible for building bone — to function optimally, promoting healthy bone structure and growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelps maintain bone mineral density:\u003c\/strong\u003e Over time, bone remodelling slows, which can reduce density.
