Description
Weekly Vitamin D3 + K2 delivers 3000IU vitamin D3 (cholecalciferol) and 100µg vitamin K2 (MK-7) per capsule, formulated for once-weekly intake. Both are fat-soluble and accumulate in tissue; the weekly cadence gives a 428 IU/day average — NHS-compliant 107% NRV. Combines the two fat-soluble vitamins most-discussed together for bone and immune-system support. 90 capsules per bottle — 90 weeks (~1.7 years) supply at one capsule weekly.
Per 1-capsule serving (once weekly)
- Vitamin D3 (cholecalciferol) — 75µg / 3,000IU (1,500% NRV per weekly capsule)
- Vitamin K2 (menaquinone-7 / MK-7) — 100µg (133% NRV per weekly capsule)
UK-authorised health claims (vitamins & minerals)
- Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones, the maintenance of normal teeth, the maintenance of normal muscle function, normal absorption and utilisation of calcium and phosphorus, normal blood calcium levels, and has a role in the process of cell division
- Vitamin K contributes to normal blood clotting and to the maintenance of normal bones
Key features
- Weekly cadence — fat-soluble vitamins formulated for once-weekly intake (428 IU/day D3 average, NHS-compliant)
- Pairs the two fat-soluble vitamins most-discussed together for bone and immune-system support
- 90 capsules · 90 weeks supply (~1.7 years) at one capsule weekly
- Vegetarian · UK-manufactured to GMP standard (note: not vegan — cholecalciferol is animal-sourced)

About the ingredients
Vitamin D3
Vitamin D is a fat-soluble vitamin the body uses for normal calcium and phosphorus absorption, bone and muscle maintenance, and immune function. UK NHS guidance recommends 10 µg/day (400 IU) for everyone aged four and over from October to March, when UK latitude limits the skin's ability to synthesise vitamin D from sunlight.

Vitamin K2 (Menaquinone)
Vitamin K is the umbrella name for a family of fat-soluble compounds needed for the normal synthesis of clotting factors and for the activation (γ-carboxylation) of several bone and vascular proteins. Vitamin K1 (phylloquinone, found mostly in green vegetables) and vitamin K2 (menaquinones, found in fermented foods and animal products) are the two main subgroups. The UK-authorised health claims apply to "vitamin K" generically; the K2 supplement category is positioned around tissue-distribution and half-life differences between the forms, but UK regulation does not distinguish them at label level.
