Vitamin K2 offers significant benefit for supporting bone health – more than vitamin K1. Although vitamin K2 offers well-recognized postmenopausal bone support, because it has no estrogenic effects it also provides nutritional (not therapeutic) support to other populations as well, including anorexics, dialysis patients, individuals with Parkinson's disease, those who have cirrhosis of the liver, individuals who have had a bone marrow transplant, those immobilized after a stroke, and individuals on chronic steroid therapy. Vitamin K2 also supports a healthy heart and blood vessels. Thorne's vitamin K2 supplies 1 mg of vitamin K2 per drop. Research shows that 15 mg three times daily can be safely used. The concentrated liquid and the bottle's metered dispenser make use easy and convenient.

Vitamin K2 provides support for blood vessel health by its role in better enabling the body to move calcium to the bones, which keeps the calcium out of the soft tissues, such as the blood vessels and the kidneys. Thorne's Vitamin K2 Liquid supplies 1 mg of vitamin K2 per drop.
