The natural, clinically proven vitamin k2 (MK-7): the complete MenaQ7® scientific white paper

MenaQ7® is the natural, clinically proven Vitamin K2 as MK-7, backed by nearly two decades of clinical evidence, all gathered in a single comprehensive scientific white paper.

A comprehensive scientific white paper consolidating nearly two decades of proprietary and published clinical research on MenaQ7® Vitamin K2 as MK-7 (menaquinone-7) is now available. The document covers established evidence in bone and cardiovascular health, vitamin K status across the lifespan, and emerging research in metabolic health and brain function — providing a structured, evidence-graded reference for R&D teams, regulatory and scientific affairs professionals, and brand owners in the dietary supplement and functional food industry.

A single ingredient with unmatched evidence

Not all Vitamin K2 ingredients are scientifically equivalent. The bioform, manufacturing process, and clinical validation program behind an ingredient determine its credibility — and, ultimately, your product’s ability to substantiate health claims that can target adults and children.

MenaQ7® Vitamin K2 MK-7 is the first and most clinically proven natural Vitamin K2 as MK-7 (menaquinone-7), an essential vitamin within the vitamin group known for coagulation-related functions, supported by numerous proprietary clinical studies covering all life stages. Produced through a controlled natural fermentation process using non-GMO Bacillus strains on an allergen-free substrate, similar to how bacteria contribute menaquinones in fermented foods, MenaQ7® is a highly pure, bioavailable ingredient widely regarded as a gold standard — with a general purity exceeding 97% and an isomeric purity of 99.8% in the bioactive all-trans MK-7 form.

This white paper consolidates nearly two decades of proprietary and published research into a structured scientific reference document to support formulation decisions.

Built for every function involved in ingredient decisions

The white paper is structured to serve cross-functional teams — from R&D and regulatory affairs to brand management and purchasing. Whether assessing clinical evidence, evaluating claim strategies, or benchmarking ingredient quality, the document provides the relevant data for each function.

Inside the MenaQ7® clinical white paper

Vitamin K2 (as MenaQ7®) supports health through a dual calcium metabolism mechanism: it activates osteocalcin to mineralize bones and matrix Gla protein (MGP) to protect against arterial calcification. This white paper covers the full scientific rationale, from this foundational biology to randomized controlled trial data on bone strength and vascular health, all supported by a strong safety profile. It also explains the essential role of vitamin K forms in physiology: vitamin K1 from green leafy vegetables is rapidly cleared by the liver after absorption, whereas vitamin K2 as MK-7 works the same way mechanistically but has a longer biological half-life in the bloodstream and is effective at lower doses than MK-4. The dossier also reviews dietary sources and forms, including Natto as the richest source, alongside hard cheeses, egg yolks, grass-fed butter, and other animal products; it notes that animal tissues synthesize MK-4 and that cheeses provide MK-8 at about 10–20 µg per 100 g.

Executive summary

• The Vitamin K Family — chemistry, sources, and regional intake recommendations
• MenaQ7® — manufacturing process and quality specifications
• Pharmacokinetics and Mechanism of Action
• The Calcium Paradox — Vitamin K2, Vitamin D, and Magnesium, including how it supports bone calcification, helps stop vascular calcification, activates osteocalcin for bone health, and enhances calcium incorporation into bone with vitamin D, with relevance to bone mineral density and bone support-focused formulation interest
• Clinical Evidence — bone health in adults and children, cardiovascular health in adults, vitamin K status, emerging research
• Safety Profile — these nutrients have a very low potential for toxicity, there is no established Tolerable Upper Intake Level for vitamin K, and no known toxicity has been identified for high doses of vitamin K2 or routine use in supplements

For patients receiving warfarin or related medications, avoiding large vitamin K fluctuations is important to preserve normal blood clotting control during anticoagulant treatment; this interaction should be assessed clinically because long-term anticoagulant exposure may affect bone quality and alter benefit-risk considerations.
