Ultra K2-D3 provides the recommended amount of vitamins K2 and a liberal amount of vitamin D3, the preferred form of vitamin D. These vitamins are specific for calcium metabolism, bone health and density retention. Research has recently shown the majority of North Americans are deficient in these vitamins, especially during dark winter months, and thought to be directly responsible for a portion of adult bone breakage. As a pleasant tasting, chewable tablet, Ultra K2-D3 is easily taken by people who find it difficult to swallow supplements and need vitamins K2 and D3.

Vitamin K2, also known as menaquinone-4, menaquinone-7, menaquinone-9 and, are required for modification of proteins that deposit calcium in bones. Vitamin D3 is required for absorption of calcium from the gut, regulation of serum calcium levels, and regulation of at least 1000 genes.
