Vitamin K2 MK-7
Calcium metabolism · Bone health
100 mcg
Part of PRIME / AM, taken in the morning.
Form, dose and role.
- What it is
- Vitamin K2 as menaquinone-7 is a fat-soluble vitamin involved in normal blood clotting and the maintenance of normal bones.
- Why DEXO chose it
- K2 is included as part of PRIME's D3-centred nutritional architecture, supporting calcium metabolism, bone health and long-term physical performance.
- Why this form
- Menaquinone-7. MK-7 has a longer circulating half-life than MK-4 at comparable intakes, which suits a once-daily format.
- Why this dose
- 100 mcg is a common, conservative daily amount used alongside vitamin D.
- Its role in the system
- Vitamin K helps activate proteins involved in normal bone and calcium metabolism. A double-blind trial found that 100 mcg/day of MK-7 — the amount in PRIME — improved osteocalcin carboxylation. K2 is not connected to testosterone here.
