NOW Foods Vitamina D-3 y K-2, 120 Cápsulas Vegetales (Paquete de 2)

What is vitamin D3 and K2 and why combine them?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are two fat-soluble nutrients that work synergistically to maintain bone and cardiovascular health. While vitamin D3 promotes calcium absorption in the intestine, vitamin K2 activates proteins like osteocalcin that direct calcium to bones and teeth, preventing its deposition in soft tissues like arteries. This combination is key for balanced bone metabolism and healthy circulation.

Each NOW Foods vegetable capsule provides 1000 IU of vitamin D3 and 45 mcg of vitamin K2, in a carefully developed formula to maximize bioavailability and efficacy.

Is vitamin D3 or D2 better? And vitamin K2?

Vitamin D3 (cholecalciferol) is the form most similar to that produced by the human body after sun exposure, and has been shown to be more effective than vitamin D2 (ergocalciferol) at raising and maintaining blood levels of vitamin D.
