Best Vitamin A D

Isotonix Vitamin D with K2 contains vitamin D3, the metabolically active form of vitamin D, along with vitamin K2, a form of vitamin K which supports vascular health and calcium utilization. Vitamin D plays an important role in bone health, heart health and immune support while working with vitamin K to support normal absorption of calcium, and promote healthy arteries. Isotonix Vitamin D is the first of its kind to deliver both of these powerful vitamins with isotonic delivery. Vitamin K is included in Isotonix Vitamin D with K2 because of its unique partnership with vitamin D. Vitamins K and D work together to support calcium absorption and utilization. Vitamin K supports the normal delivery of calcium to the bones and promotes healthy arteries. At least two naturally occurring forms of vitamin K have been identified and are known as K1 and K2. While there are many similarities between these two forms of vitamin K, they are distinguished by their important differences. The most significant difference between K1 and K2 is their chemical structure, which results in different pharmacokinetic properties. Vitamin K1 is retained primarily in the liver where, at high doses, it may interfere with the action of warfarin and other anticoagulant medications. Vitamin K2 has a different mechanism of action. It is transported primarily to bones and blood vessels. Vitamin K2 helps to maintain bone mass, support calcium utilization and promote elasticity of blood vessels. Some studies have concluded that vitamin K2 does not interfere with anticoagulant medications.* However, 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 .

Vitamin D is known as essential when it comes to building strong teeth and bones, but did you know that the primary source for Vitamin D is not always food?** It’s the sun! Unfortunately, the sun does not shine all of the time – and on some days, clouds get in the way or an indoor job might keep us from the sun altogether – so your body may not be getting all of the Vitamin D it needs. Vitamin D3 is a more potent and bioavailable form compared to D2. That’s why we released a Vitamin D potency – 5000 IU! This formula provides a super-dose of D3, an active and potent form of Vitamin D, so you can be sure that you are getting the most potent version of what your body needs.** And Vitamin D does more than help form healthy teeth and bones; it also assists the immune system.** No wonder medical researchers around the globe are studying the effects of Vitamin D more than ever before!
