Vitamin K2 MK-7 – Menaquinone-7 for Nutraceutical and Functional Formulations
Vitamin K2 MK-7 (Menaquinone-7) is a fat-soluble form of vitamin K2 widely used in dietary supplements and functional nutrition products. It is particularly relevant to formulations focused on bone health, calcium metabolism, and cardiovascular wellness.
ProMaxBio supplies Vitamin K2 MK-7 in different concentrations and preparation formats, including powder and oil-based options, to support professional ingredient sourcing and customized formulation requirements.
Vitamin K2 MK-7 Product Overview
Vitamin K2 MK-7 belongs to the menaquinone family of vitamin K compounds. Compared with Vitamin K2 MK-4, MK-7 has a longer side chain and generally exhibits a longer circulating half-life in human pharmacokinetic studies.
This characteristic has contributed to its popularity in nutritional supplement development, particularly in formulations designed for daily vitamin K intake.
For manufacturers, the selection of Vitamin K2 MK-7 should consider active concentration, preparation format, stability, processing compatibility, and the intended finished-product dosage.
Vitamin K2 MK-7 Functional Applications
1. Bone Health and Calcium Metabolism
Vitamin K contributes to the maintenance of normal bones through its role in the activation of vitamin K-dependent proteins.
Vitamin K2 MK-7 has been investigated in relation to osteocalcin carboxylation, bone metabolism, and selected markers of skeletal health.
These properties make Vitamin K2 MK-7 relevant to bone health formulations, particularly those combining several nutrients involved in skeletal function.
2. Cardiovascular and Vascular Research
Vitamin K-dependent proteins, including matrix Gla protein, are involved in biological processes associated with vascular calcification.
Clinical research has examined the relationship between Vitamin K2 supplementation and selected cardiovascular or vascular biomarkers.
However, effects on clinical cardiovascular outcomes have not been conclusively established, and product claims should reflect the evidence and regulatory requirements of the target market.
3. Healthy Aging Nutrition
Interest in maintaining bone health and nutritional status during aging has contributed to the development of vitamin K2-containing supplements.
Vitamin K2 MK-7 is frequently considered in multi-nutrient formulations for adults seeking nutritional support for long-term skeletal health.
Its inclusion should be based on the intended nutritional purpose rather than unsupported anti-aging claims.
Vitamin K2 MK-7 Formulation Combinations
Combination with Vitamin D3
Vitamin D contributes to normal calcium absorption and utilization, while vitamin K participates in the activation of vitamin K-dependent proteins.
The Vitamin D3 and Vitamin K2 MK-7 combination is widely considered in bone health and calcium metabolism formulations.
Manufacturers should select appropriate concentrations and evaluate the stability of both vitamins in the intended dosage form.
Combination with Magnesium Glycinate
Magnesium contributes to normal bone maintenance and supports numerous enzymatic processes.
Combining Vitamin K2 MK-7 with Magnesium Glycinate offers a formulation concept for multi-nutrient bone health supplements.
Developers should consider elemental magnesium content, dosage requirements, and finished-product compatibility.
Combination with Calcium
Calcium is an essential mineral for the maintenance of normal bones and teeth.
Vitamin K2 MK-7 can be incorporated into calcium-containing nutritional formulations, subject to appropriate dosage design and regulatory requirements.
Combination with Vitamin D3 + Magnesium
Multi-nutrient combinations involving Vitamin K2 MK-7, Vitamin D3, and Magnesium are of interest to manufacturers developing comprehensive bone health products.
Such formulations require careful consideration of ingredient concentrations, serving sizes, stability, and the needs of the intended consumer population.
Vitamin K2 MK-7 Powder and Oil Formulations
Vitamin K2 MK-7 is available in different preparation formats to meet the needs of commercial supplement manufacturers.
Powder Preparations
Powder-based Vitamin K2 MK-7 preparations may be suitable for capsules, tablets, sachets, and powdered nutritional blends.
Because MK-7 is typically used at microgram-level serving amounts, accurate dilution, mixing uniformity, and analytical verification are particularly important.
Oil-Based Preparations
Oil-based Vitamin K2 MK-7 preparations may be considered for softgels, oil drops, and other lipid-based delivery systems.
Manufacturers should evaluate carrier oils, active concentration, oxidation stability, and compatibility with other fat-soluble ingredients.
Vitamin K2 MK-7 Quality and Stability Considerations
Professional ingredient buyers should evaluate:
- Verified MK-7 concentration and assay method
- All-trans MK-7 content and cis-isomer profile
- Preparation format and carrier composition
- Fermentation-derived or synthetic manufacturing route, where relevant
- Stability under light, oxygen, temperature, and humidity exposure
- Finished-product content uniformity
- Heavy metals, residual solvents, and microbiological specifications
- Packaging, storage conditions, and shelf-life documentation
- Regulatory suitability for the intended market
The all-trans form is particularly important when evaluating Vitamin K2 MK-7 quality because isomer composition can affect the biological relevance of the measured material.
Manufacturers should request detailed specifications and appropriate analytical documentation for the selected grade.

Selecting a Suitable Grade
Choose the preparation according to your target active content, delivery format and processing requirements. Oil preparations may be considered for oil-based formulations; powder preparations can be evaluated for capsules, tablets and powder blends. Confirm carrier composition, assay basis, all-trans content and suitability through product-specific documents and sample trials.
Frequently Asked Questions
Does a 1% preparation contain 1% active MK-7?
Confirm the specification against the product-specific assay and reporting basis. At a verified 1% MK-7 concentration, 1 g of preparation contains approximately 10 mg MK-7. This is a composition calculation, not a dosage recommendation.
Is every grade fermentation-derived or all-trans?
Production route, carrier composition and all-trans content must be confirmed for the selected grade. Concentration alone does not establish these characteristics.
Can specifications be customized?
Customized concentrations can be discussed. Send ProMaxBio your required preparation, active content, application, quantity and destination market to request specifications, samples and available quality documents.
