Vitamin D & K

Our Vitamin D & K Support collection is designed to provide two of the most essential nutrients for overall wellness — working together to support strong bones, balanced immunity, and cardiovascular health. Vitamin D plays a critical role in calcium absorption, immune defense, and mood regulation, while vitamin K2 helps ensure calcium is properly directed into the bones and away from arteries for optimal heart and bone support.

These formulas feature clinically studied, bioavailable forms of vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone-7) for superior absorption and effectiveness. Together, they promote bone density, balanced inflammation, healthy blood vessels, and hormone function — foundational benefits for energy, longevity, and whole-body vitality.

At Rathdrum Drug & Nutrition Center, we only carry pharmaceutical-grade, third-party tested supplements to ensure purity, potency, and consistency. Each product in this collection is chosen for clinical integrity and trusted results, helping you maintain optimal vitamin D and K levels for year-round immune strength and bone support.
