Vitamin D3 + K2
A pairing of two fat-soluble nutrients — vitamin D3 and vitamin K2 — that work together to support the body’s handling of calcium, bone health, and normal immune function.
Two nutrients that work better together
Vitamin D3 (cholecalciferol) is the form the body makes from sunlight and helps you absorb calcium; vitamin K2 (menaquinone) helps direct that calcium toward bone. At Meridian this pairing is offered as a well-characterized dietary supplement — quality-tested and clearly explained — to round out a foundational routine. It is not a drug, and it is not intended to diagnose, treat, cure, or prevent any disease.
Supporting how the body uses calcium
Vitamin D3 supports normal calcium absorption from the diet, while vitamin K2 activates proteins that help guide calcium into bone. Taken together as a daily oral dose, the two nutrients complement each other and are absorbed best alongside a meal containing fat.
- ✓Vitamin D3 supports normal absorption of dietary calcium
- ✓Vitamin K2 helps activate proteins that direct calcium toward bone
- ✓Taken as a simple once-daily oral dose, ideally with food
