Vitamin D Plus K: Synergistic Support for Bones, Heart, and Immunity*

Vitamin D Plus K by Klaire Labs provides a powerful, bioavailable combination of two essential fat-soluble vitamins that work together to support whole-body health. Featuring high-potency Vitamin D3 and a premium form of Vitamin K2, this formula is designed to support healthy calcium metabolism, which is critical for bone mineralization and cardiovascular wellness. It also plays a key role in modulating a healthy immune response, making it a foundational supplement for daily wellbeing.*

How It Works: A Partnership for Optimal Health

Vitamins D and K are structurally similar and work as a team to direct calcium to where it’s needed most in the body—and keep it out of where it doesn’t belong.

Directing Calcium for Bone & Heart Health
Vitamin D3 enhances the absorption of calcium from the diet. Vitamin K2, in its highly bioavailable MK-7 form, then activates proteins that help integrate that calcium into the bone matrix. Critically, Vitamin K2 also helps maintain a healthy calcium balance in vascular tissues, supporting arterial flexibility and overall cardiovascular function.*

Modulating a Healthy Immune Response
Recent studies have highlighted the importance of both Vitamin D and Vitamin K in the healthy functioning of the innate and adaptive immune systems. This formula provides a potent dose of each to ensure your body’s natural defense system is well-supported.*

  • Provides a bioavailable combination of 5,000 IU of Vitamin D3 and 100 mcg of Vitamin K2*
  • Supports healthy calcium metabolism and bone mineralization*
  • Promotes a healthy calcium balance in vascular tissues for cardiovascular health*
  • Supports healthy functioning of the immune system*
  • A convenient, one-capsule daily formula
