Natural Vitamin K2 MK4 Plus MK7 High-Potency - Bone & Arterial Support

Our review finds this high-potency vitamin K2 formula best suited for adults focused on bone and arterial health who want a product dosed like the clinical studies. In this review the standout feature is the dual-formulation: a very large 15,000 mcg MK-4 dose paired with 60 mcg MK-7 in a single, easy-to-swallow vegecapsule, which mirrors dosing used in some Japanese and European studies; that makes it appealing to people seeking clinically inspired supplement levels rather than diluted, lower-dose options.

Key Features

• High MK-4 dose: Provides 15,000 mcg of MK-4 per capsule to match dosing used in relevant clinical work supporting bone health.
• Dual K2 forms: Includes 60 mcg of MK-7 alongside MK-4 to offer the complementary benefits of both long- and short-chain K2 homologs.
• Pharmaceutical-grade purity: MK-4 is reported as less than 1% cis form and MK-7 as less than 4% cis form, reflecting attention to isomer purity.
• Third-party tested: Label claims are documented by FDA-registered, USA-based outside labs, which supports product quality and content accuracy.
• Minimal excipients: Capsules contain only essential fillers to occupy the small #4 vegecapsule, keeping the formulation concentrated.
• GMP compliance: Manufactured under full GMP practices, which helps ensure consistent product handling and quality.

Who It's For

This product is aimed at adults already familiar with vitamin K2 therapy or those working with a healthcare professional who want a formulation that mirrors dosings used in Japanese and European MK-4/MK-7 studies. It suits people who value documented laboratory verification, pharmaceutical-grade purity, and a concentrated capsule for convenience.

It is not ideal for those seeking low-dose daily maintenance or people sensitive to high-dose supplements without prior medical guidance; anyone on anticoagulant medication should consult a clinician before use.

Pros & Cons
