Better together! Emerging research suggests that vitamins D3 and K2—two key nutrients for efficient calcium usage in the body—may have an even more beneficial effect when taken together. Swanson Vitamins D3 & K2 offers these bone and heart health helpers in a convenient, one-a-day veggie capsule. What if you already supplement with vitamins D and K or get them from your diet? Now Swanson offers a low-dose D3 & K2 combo just for you. Swanson low dose Vitamins D3 & K2 provides 50 mcg (2,000 IU) of vegan D3 derived from lichen and 75 mcg soy-free chickpea-sourced K2 as MK-7 in a once-daily veggie cap to help maintain cardiovascular health and promote strong, healthy bones. Vitamin D helps build strong bones by increasing the body’s absorption of calcium and phosphorus. In supplement form, it is available as ergocalciferol (D2) or cholecalciferol (D3). Studies indicate that D3 may be the more potent and longer-acting form preferred by the body. Similarly, vitamin K is found in K1 and K2 forms. K2 is of particular importance for the health of bones and cardiovascular system as it helps direct calcium out of the arteries and to the bones. K2 is made up of a series of menaquinones, of which menaquinone-7 (MK-7) is most efficiently absorbed and bioavailable. New understanding of the interaction of vitamins D and K suggests that vitamin D enhances the concentration of bone proteins that rely on vitamin K for healthy bone formation and in turn, the essential mineralization stimulated by vitamin K may be positively impacted by the presence of vitamin D.
