Product Information
Modern diets generally don't provide enough vitamin D3 and K2. You can now optimise your intake with our superior-strength formula that comes in a convenient and flexible dose. This combination product is an excellent choice for all adults, but particularly helpful for those aged 50+, with specific concerns around bone health and those looking to support their immune system.
Each easy-to-swallow, taste-free capsule provides an impressive 50µg (1000% NRV) vitamin D3 and 90µg (120% NRV) vitamin K2, both of which work synergistically in the body and contribute to the maintenance of normal bones.
What do vitamin D3 and K2 contribute to?
- Vitamin D3 contributes to the maintenance of normal bones, teeth, muscle function and the normal absorption and utilisation of calcium/ phosphorus. Vitamin D3 also contributes to normal cell division and the normal function of the immune system, and healthy inflammatory responses. Find out more about vitamin D here.
- Vitamin K2, on the other hand, contributes to the maintenance of normal bones and blood coagulation. Find out more about vitamin K here.
Since vitamin D is an indispensable nutrient for normal muscle function our Nutrition Advisors recommend Vitamins D3 2000iu (50µg) & K2 90µg alongside CoQ10 to support heart muscle function. To find out more about heart health here.
Our bodies obtain vitamin K as vitamin K1 (phylloquinone), found in green leafy vegetables, and vitamin K2 (menaquinone), which is naturally produced by the live bacteria in our digestive tract. The body absorbs vitamin K2 better than K1, so we choose to use it in this formula.
Vitamin K2 (menaquinone) exists in two forms: synthetic MK-4 and natural MK-7. Published studies suggest natural MK-7 is more bioavailable (readily absorbed) than synthetic MK-4. Manufactured using a unique extraction process, our vitamin K2 derives from chickpea protein, not soya (for people who need to avoid soya), our formula contains pure, natural, full-spectrum MK-7.
We’ve chosen to supply our superior-strength formula in small capsules not tablets to further aid absorption. We've suspended vitamin D3 and K2 in sunflower oil, along with rosemary extract and vitamin E, to keep it fresh and stable.
To meet our strict quality standards, we manufacture and package our formulas in UK factories working to strict Good Manufacturing Practice (GMP).
This product is suitable for vegetarians not vegans.

"Essential Above And Beyond The Core"

Since the beginning of C***9, Vitamin D and K have been a staple for me, above and beyond the baseline multivitamins. After two years of testing my blood levels, I am still just about in the normal, but not yet optimal range. I find that I get f**s/colds less and when I feel something coming, this and S**bucol helps stop it from progressing.
