Complete Support for Bone Strength & Cardiovascular Health
Extra K + D3 is a comprehensive daily formula that helps ensure calcium ends up where it belongs—building strong bones and supporting a healthy heart. While calcium is vital, it's only part of the picture. Without proper guidance from nutrients like Vitamin K2, D3, and Magnesium, calcium can accumulate in the wrong places, such as arteries and soft tissue.
This formula combines three synergistic ingredients to help your body absorb, direct, and regulate calcium effectively. Whether you're taking calcium supplements, navigating bone loss concerns, or just want to proactively support heart and bone health, Extra K + D3 is a smart, complete foundation.
Why We Love It
Most calcium-support products stop at D3 and K2. This one goes further—adding magnesium to help regulate calcium balance, improve vascular function, and reduce risk of calcium buildup in soft tissues. It's ideal for anyone wanting to simplify their supplement routine while covering all the key nutrient gaps that affect both bone and heart health.

What’s Inside
-
Vitamin D3 (Cholecalciferol) – 5,000 IU
Enhances calcium absorption from food and supplements. -
Vitamin K2 (as MenaQ7® MK-7) – 180 mcg
Directs calcium into bones and away from arteries. -
Magnesium (as Magnesium Bisglycinate Chelate) – 100 mg
Helps regulate calcium transport, supports heart rhythm and vascular tone.
How It Works
Calcium is essential for bones, but without vitamin K2 and magnesium, it can go off-course—building up in arteries instead of strengthening your skeleton. Vitamin D3 increases calcium absorption. K2 activates proteins that deposit calcium into bones and prevent it from sticking to blood vessels. Magnesium supports muscle and nerve function and ensures proper calcium balance throughout the body.
This trio works together to protect your bones, heart, and long-term vitality.
When to Use It
-
If you're taking calcium supplements and want to ensure safe absorption
-
During midlife or postmenopause, when bone support becomes more critical
-
If you're at risk of cardiovascular calcification or on statin/acid-blocker medications
-
As a daily bone and heart support strategy
Suggested Use
Take 1 softgel daily with food or as directed by your healthcare provider. For best results, pair with a meal containing healthy fats to improve absorption.
Choosing the Right Support
If you prefer a liquid format for flexible dosing and a simpler formula, our Vitamin D3 + K2 Drops may be a better fit. These drops deliver the essential D3 and K2 combo to support calcium balance—great for those focused on basic bone and heart support.
