Maximise D3 and K2 absorption with this enhanced oil based formula
A liquid combination of vitamin D3 (1000 IU / 25mcg) and natural vitamin K2 (50mcg) per 10 drop serving. The oil based format provides the fat soluble carrier that D3 and K2 require for absorption, eliminating the need to take with a fatty meal. The liquid format also allows flexible dosing: each drop provides approximately 100 IU D3 and 5mcg K2, so the dose can be scaled up or down precisely.
The D3 and K2 pairing ensures calcium absorbed through vitamin D's action is directed into bones rather than depositing in arteries. This product provides a lower D3 dose per serving than the Vegan capsule (1000 IU vs 2500 IU), making it more suitable for daily maintenance in those who are not deficient, for children, or for those who prefer to combine with other D3 sources for a specific total dose.
Key benefits:
- Maximum absorption in oil based form
- Bone and immune function support
- Easy drops for precise dosing

Directions for use:
Take 10 drops per day with food.
The drops can be placed directly on food, into a drink or taken straight from the dropper. The oil base means absorption is already optimised, but taking with a meal further supports utilisation. The dose can be adjusted: 5 drops provides 500 IU D3, 10 drops provides 1000 IU, 20 drops provides 2000 IU. Adjust based on blood test results and professional guidance.
If taking blood thinning medication, consult your prescriber before supplementing vitamin K2.
