This trio of micronutrients (calcium, vitamins D and K) play a role with regards to your bone health. Given that the calcium requirements are often covered by the food we eat, Surveal Laboratoires took care to develop Biocalcin ™️, a dietary supplement that helps cover your needs in vitamins D and K. Menaquinone-7 is known for its high content of vitamin K and more specially MK7, which has a greater bioavailability in the body than synthetic vitamin K. Surveral Laboratoires selected this form forb Biocalcin ™️. Biocalcin ™️ contains (in one capsule) 45 µg of Vitamin K2 i.e. 60% of the RDA* and 25 µg of Vitamin D, i.e. 500% of the RDA*.
