Isotonix Vitamin K2 with D3 contains vitamin K2, a form of vitamin K which supports calcium utilization, along with vitamin D3, the metabolically active form of vitamin D. Vitamin K supports the normal delivery of calcium to the bones, while vitamin D plays an important role in bone health, working with vitamin K to support normal absorption of calcium. Isotonix Vitamin K2 is the first of its kind to deliver both of these powerful vitamins with isotonic delivery. Vitamin K2 and D3 are paired together in Isotonix Vitamin K2 with D3 so they can work synergistically together to support calcium absorption and utilization. Two of the more common forms of vitamin K are K1 and K2. While there are many similarities between these two forms of vitamin K, they can be distinguished by their important differences, the most significant being their differing pharmacokinetic properties. Vitamin K1 disappears rapidly from the blood, while vitamin K2 persists in the blood’s circulation for a longer time. Isotonic, which means “same pressure,” bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state. Isotonix dietary supplements are delivered in an isotonic solution. This means that the body has less work to do to in obtaining great absorption. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.
