Powerhouse Blend for Bone and Heart Health

Vitamin K2 and D3 Complex are two vital fat-soluble vitamins that, when combined together, deliver a synergistic powerhouse blend that improves skeletal health while protecting against hardened arteries. This high-power, fast-absorption blend delivers MK-7 vitamin K and vitamin D as cholecalciferol – the highest quality and most bioavailable form of both vitamins.

Product Highlights

Supports optimal calcium absorption and distribution
Reduces arterial calcification as well as supporting heart and joint health
Powerful 2-in-1 blend for maximum bioavailability
Certified third-party lab tested for purity and contaminants

Our Experts Say

This pharmacist-formulated 2-in-1 support blend clinically combines essential vitamin K2 MK-7, the most bioavailable K vitamin, and the sun imitator, vitamin D3 at 10,000 IU to provide optimal calcium absorption and distribution. Maximum strength in one acid-resistant and easy-to-swallow capsule made to prevent arterial calcification and promote strong bones.

A Powerful Synergistic Blend
This bioavailable K2 and D3 formulation is the perfect 2-in-1 pair to enhance calcium absorption. D3 regulates the absorption and circulation of calcium, while K2 directs calcium to where you need it most for a strong skeletal system.
Maximum Vitamin K Bioavailability
Vitamin K2 as MK-7 has a longer half-life than other types of vitamin K. That means it can remain active for up to 72 hours in the body compared to 1-6 hours. This allows for once-daily dosing while effectively supporting normal blood clotting activities, and improved calcium absorption and distribution.
Guaranteed Potent and Pure
Manufactured in a GMP-compliant facility, our Vitamin K2 and D3 Complex delivers an optimal dose in every capsule, with no contaminants or unnecessary fillers. Third-party tested; top quality and integrity guaranteed.

How to Use

Daily Use

Take one capsule with water, preferably at mealtime, or as directed by your healthcare practitioner.

What's in the Bottle

Vitamin K2 as MK-7
Vitamin K2 is needed for a variety of processes in the body, such as blood clotting, activating proteins, preventing calcium build-up in the arteries, preserving bone tissue integrity, and promoting healthy brain development. It can also be useful for reducing fractures and osteoporosis risk.
Vitamin D3 as cholecalciferol
Vitamin D3 helps maintain normal levels of phosphorous and calcium to promote strong bones by increasing their absorption into the bloodstream from foods we eat.
