Vitamin D + K2

Vitamin D3 and K2 work together to benefit bone health, cardiovascular support, and healthy immune function. Maintaining an optimal level of vitamin D throughout all stages of life helps maintain strong bones and healthy immune function. Adding vitamin K2 helps move calcium to the bones to protect soft tissues, such as the arteries and kidneys, from calcification. Combining vitamins D3 and K2 provides greater benefit together than each offers separately. Thorne's Vitamin D + K2 supports a healthy heart and blood circulation; promotes bone health and calcium absorption; benefits immune function and the combination provides advanced bone health support. The vitamin K2 in this formula is MK-4, the most clinically studied form of vitamin K.
