Key Benefits

  • Promotes calcium balance and bone health.
  • Supports heart health and vascular function.
  • With 3 forms of vitamin K for maximum health benefits.


Vitamin K is crucial for maintaining cardiovascular health and bone strength. It helps regulate calcium, ensuring it stays in the bones and prevents it from accumulating in blood vessels and soft tissues in the body. While this vitamin is important to support these processes, many struggle to get enough vitamin K from their diets, especially if they limit foods like meat, dairy, and leafy greens. That’s where a vitamin K supplement comes in.

Super K delivers a potent 2600 mcg of vitamin K from both K1 and two forms of K2. Vitamin K1 (phylloquinone) supports blood clotting, while K2—comprising MK-4 and MK-7—enhances bone density and reduces fracture risk. MK-4 absorbs quickly, and MK-7 stays active longer, giving you the best of both worlds.

Taking Super K daily ensures your body receives these essential nutrients for strong bones, a healthy heart, and optimal vascular function.
