Why it works
Vitamin D is the most common deficiency in adults who work indoors, and it affects everything from bone density to immune function to mood. Vitamin D increases calcium absorption. Vitamin K2 tells the body where to put it: into bone and teeth, not soft tissue. The two are meant to be taken together.
This formula pairs 5,000 IU of D3, the form the skin makes from sunlight, with 100 mcg of K2 as MK-7, the long-acting form, plus a small amount of calcium and BioPerine to support absorption. Two-month supply per bottle.
Benefits
Bone strength*
D3 supports calcium absorption. K2 activates the proteins that bind calcium into bone.*
Cardiovascular support*
K2 as MK-7 supports normal calcium metabolism and arterial health.*
Immune function*
Vitamin D supports normal immune response, particularly during winter months.*
Mood and muscle*
Adequate vitamin D supports a healthy mood and normal muscle function.*
