Vitamin K2 for Bone Health
Supporting Strong Bones at Every Stage of Life
Vitamin K2, particularly in the form of menaquinone-7 (MK-7), plays a critical role in maintaining bone health. It supports the activation of proteins that help bind calcium to the bone matrix, contributing to bone strength, structure, and density.1
Vitamin K2 supporting Calcium Uptake
We all know the importance of calcium,5 but did you know about vitamin K2?
It activates proteins like osteocalcin, enabling them to bind calcium,6,7,8 which supports calcium uptake for strong bones. This, in turn, improves bone density and strength in postmenopausal women.9,10,11,12
Vitamin K2 also acts as a coenzyme for Matrix-Gla protein, which is involved in soft tissue calcification.13,14,15,16
Additionally, vitamin D plays a crucial role by aiding calcium absorption and promoting the synthesis of vitamin K-dependent proteins.¹7

Emerging Science: Probiotics and K2 in Bone Health
A recent preclinical study (Santos et al., 2025)18 investigated the combined effects of Vitamin K2 (MK-7) and the probiotic Limosilactobacillus reuteri in a model of postmenopausal bone loss.
The study found that:
- The combination significantly improved femur stiffness and elastic modulus
- Cortical bone volume and thickness were restored to levels seen in healthy controls
- Trabecular bone microarchitecture showed positive trends
- The combined treatment outperformed either intervention alone, suggesting a synergistic effect
These findings highlight the potential of combining K2 with targeted probiotics to support bone health in aging populations.18
Clinically Supported Benefits of Vitamin K2 (MK-7)
- Supports Bone Strength: Clinical studies show that Vitamin K2 (MK-7) helps maintain healthy bone mass and structure, particularly in postmenopausal women.18
- Enhances Bone Mineral Density: Higher vitamin K intake is linked to increased bone mineral density and stronger bones.1
- Activates Key Bone Proteins: Vitamin K2 support the function of proteins involved in bone metabolism.1
- Promotes Healthy Aging: Vitamin K2 helps maintain bone health as we age by supporting the function of proteins involved in bone metabolism.4
Our Commitment to Bone Health
We offer high-quality, science-backed Vitamin K2 (MK-7) in the form of K2VITAL™ and K2VITAL™ DELTA.
These solutions are ideal for use in dietary supplements, functional foods, and other health-focused formulations. K2VITAL™ DELTA, a microencapsulated form of K2, is especially well-suited for combination products, helping to maintain stability when paired with minerals like calcium and magnesium.
Together, these nutrients play a critical role in supporting bone strength and overall skeletal health.
