Thorne Vitamin K

£30.00

The most comprehensive vitamin K supplement available — combining K1, K2 as MK-4 (5 mg), and K2 as MK-7 (MenaQ7, 90 mcg) in a single capsule that covers coagulation, bone mineralisation, and arterial calcium regulation…

• Vitamin K2 as MK-4 at 5 mg is the form most concentrated in human bone, brain, pancreas, and vascular tissue — it activates osteocalcin for calcium incorporation into bone and matrix Gla protein for prevention of arterial calcification, at a dose substantially higher than most consumer K2 supplements provide
• Vitamin K2 as MK-7 (MenaQ7) at 90 mcg is the most extensively researched long-acting K2 form, with a biological half-life of approximately 72 hours — maintaining activated K-dependent proteins between doses and providing published clinical evidence for improvements in bone mineral density and arterial flexibility
• Vitamin K1 at 1 mg supplies the primary substrate for hepatic synthesis of coagulation factors II, VII, IX, and X — the proteins that form the clotting cascade activated in response to vascular injury
• The triple-form combination provides both rapid tissue-level activity (MK-4 peaks within hours), sustained systemic coverage (MK-7 maintains activity for days), and coagulation support (K1) — a comprehensive approach that single-form supplements structurally cannot achieve
• Vitamin K contributes to the maintenance of normal bones and normal blood clotting
