Natural Factors Vitamin K2+D3+A liquid drops contain three fat-soluble vitamins with complementary roles in the development and maintenance of strong bones and teeth.

Menaquinone-7 (MK-7) is a highly bioavailable form of vitamin K2 derived naturally from natto beans. It assists in building bone mineral density by helping guide calcium toward the bones and away from tissues, such as the arteries, where it can be damaging. Only the MK-7 form has been shown to offer 24-hour protection in a single daily dose.

Vitamin D3 is the natural cholecalciferol and most bioavailable form of vitamin D. It plays a key role in the absorption of calcium and phosphorus, two minerals that are vital for proper bone mineralization and turnover.

Palmitate does not need to be converted by the body from carotenoids, making it a reliable form of vitamin A for supporting eyesight, night vision, and healthy skin and mucous membranes. Like vitamin D, vitamin A also helps support the immune system.

Each daily drop of this convenient liquid formula provides 50 mcg of vitamin K2, 1000 IU of vitamin D3, and 500 IU of vitamin A in a neutral-tasting base of MCT and organic flaxseed oils. It is non-GMO, suitable for vegetarians, and contains 120 doses per bottle.
