Why choose Isotonix Vitamin K2 with D3?
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.
Why the Isotonix® Delivery System is Great!
Isotonix Delivery System
Isotonix - the World's Most Advanced Nutraceuticals
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.
Vitamin K is a fat-soluble vitamin found in meat, eggs, dairy and natto. Although a fat-soluble vitamin, the body stores very little vitamin K2, and its stores are rapidly depleted without regular dietary intake. Natural vitamin K2, also known as menaquinone-7 (MK-7), is the most bioavailable form of K2 and has the longest half-life in the blood of any form of vitamin K. The Japanese soy food natto is particularly rich in menaquinone-7 (MK-7). Studies of natto consumption in Japan have linked menaquinone-7 to bone and cardiovascular health. The correlation of vitamin K to cardiovascular and bone health directly focuses on supporting proper calcium utilization. Vitamin K2 promotes the synthesis of proteins involved with calcium utilization, thereby supporting bone retention and arterial health.
Vitamin D3 (Cholecalciferol)
Vitamin D is a fat-soluble vitamin that is found in some foods and produced when sunlight strikes the skin and activates vitamin D synthesis. Vitamin D promotes the efficient intestinal absorption of calcium, primarily in the duodenum and jejunum by supporting the synthesis of calcium-binding proteins to promote normal calcium absorption and retention. Vitamin D also promotes the normal formation of bone and normal bone growth, and bone remodeling by osteoblasts and osteoclasts. Vitamin D deficiency can be caused by factors, such as lack of exposure to sunlight, reduced skin synthesis of vitamin D, lower dietary intake, impaired intestinal absorption and reduced metabolism to active forms of vitamin D by the kidneys, all of which increase with aging. Deficiency has been linked to numerous health concerns, and insufficient levels of this vitamin are associated with frail bones and muscle weakness.
Why are vitamins K and D included in Isotonix Vitamin K2 with D3?
Vitamins K and D are paired together due to their unique partnership. Vitamins K and D work together to promote healthy calcium absorption and utilization.
Is Isotonix Vitamin K2 with D3 safe for people on anti-coagulant medications?
Most products containing vitamin K (including K1 and/or K2) warn users taking anticoagulants not to take the product. If you are currently taking warfarin or another anticoagulant medication, you should consult your physician before taking any product containing vitamin K1 or K2.
How do I take Isotonix Vitamin K2 with D3?
Mix one capful of Isotonix Vitamin K2 with D3 with 60 ml of water. Take one serving daily.
Is it safe to take more than 1 serving of this product daily?
One serving daily of Isotonix Vitamin K2 with D3 is recommended. Check with your health care practitioner before taking additional daily servings of this product.
What are dietary sources of vitamin D?
Foods rich in vitamin D include cod liver oil, salmon, mackerel and tuna.
