    What is Calcium Complex?

    Calcium Complex has been formulated to provide targeted nutrition support for your bones. Each chewable, vanilla flavoured tablet provides calcium, along with vitamin D3 which aids calcium?s absorption, and vitamin K1, another nutrient well known for its benefits to bone health.

    Why is ours better?

    We exclusively use calcium carbonate as it has the highest percentage of calcium compared to all other calcium forms. It can also be refined and purified to the highest degree to ensure that there are no toxins. Each chewable tablet contains 400mg calcium carbonate, along with complementary vitamins D3 and K1, both proven to contribute to the maintenance of normal bones.

    A range you can trust

    This product has undergone rigorous testing by LGC?s world−class sports anti−doping laboratory, Sport and Specialised Analytical Services, for a wide range of substances banned by the World Anti−Doping Agency (WADA’) to provide the highest levels of assurance possible for athletes.


    Made in the UK.
