Synergistic D3 and K2 formula ensuring calcium reaches your bones, not bloodstream.
Vitamin D3 mobilises calcium from your diet into circulation, but without K2, that calcium deposits in soft tissues instead of bone. This formula pairs 3,000 IU D3 with 100mcg of K2 (MK7) — the most bioavailable form — to activate osteocalcin and matrix Gla protein, directing calcium precisely where your skeleton needs it.
Why This Formula
✔ Optimised 3:1 ratio — D3 and K2 at evidence-based dosages for bone and cardiovascular health
✔ MK7 form of K2 — superior bioavailability compared to MK4; longer half-life in circulation
✔ Safe for daily use — no risk of vitamin D toxicity at 3,000 IU; K2 enhances utilisation
✔ Vegetarian capsules — HPMC shell, suitable for plant-based protocols
✔ Free from lactose, gluten, wheat, yeast, dairy — clean ingredient list
Who It's For
Anyone supplementing calcium or concerned about bone density, particularly women over 40 and those with limited sun exposure. Equally valued by cardiovascular-conscious customers seeking arterial health and elastic tissue support.
