The Active Ingredient Is: Vitamin K1 (Phylloquinone)

Vitamin K1, or phylloquinone, is a fat-soluble nutrient involved in normal blood clotting and bone metabolism. This form is the dietary form of vitamin K responsible for enabling biological processes linked to coagulation and skeletal health.

This product contains phylloquinone as the sole active ingredient, with a straightforward composition that supports its primary role in bodily functions related to calcium utilisation and clotting factor activation.

What Does Vitamin K1 Do?

Vitamin K1 is involved in activating vitamin K-dependent proteins necessary for normal haemostasis and bone mineralisation, as recognised in EFSA guidance and NHS information. It plays a role in carboxylation processes that support calcium binding in bone tissue.

Clinical research suggests that vitamin K1 supplementation can influence bone health outcomes in specific populations, with Dr. Braam of Wageningen University reporting reduced age-related bone mineral density loss in postmenopausal women.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
