Bone health, immune support and more. Our powerful, synergistic formula brings together Vitamin D and Vitamin K two nutrients involved in the body's use of all-important calcium. Vitamin D3, a form of D Vitamin known as the "sunshine vitamin," is synthesized when your skin is exposed to the sun's UVB rays and plays a key role in the body's ability to absorb calcium for strong bones and more. Beyond its vital role in calcium absorption, Vitamin D3 is also a powerful immune support supplement, perfect for the cold winter months. We combine it with Vitamin K2, a form of Vitamin K that helps transport the calcium away from blood vessels and joints to where you need it most your bones and teeth. Each serving of Solaray Vitamin D3 and K2 supplements provides 125 mcg (5000 IU) of Vit D as Cholecalciferol and 50 mcg of Vit K2 as Menaquinone-7, or MK7, from fermented chickpea. Our D3K2 is made without soy, and like all Solaray products, is lab verified for purity, potency and identity. Confidence in the Solaray name is just one of the reasons weve been around so long and maintain our place as a leader in the industry. Unlike many other companies, we manufacture almost all our own products, which gives us the ability to thoroughly test and screen raw ingredients for the slightest amount of impurities and manage the production process to provide the best possible quality. Rest assured, only the purest formulas ever reach your cabinet. And because we are always committed to leaving the world a little better than we found it, we now package this product in 100% post consumer recycled plastic bottles.
