Market
Menaquinone-7 (vitamin K2, MK-7) in the United States is primarily a dietary supplement ingredient used in finished supplement formulations and private-label products. The U.S. functions mainly as a large consumption and finished-product manufacturing market, with significant reliance on imported ingredient supply alongside domestic blending/standardization and finished-goods production. Market access is shaped by FDA’s dietary supplement framework (DSHEA) and cGMP expectations under 21 CFR Part 111, with importer controls and documentation discipline important for smooth entry. Quality expectations commonly center on identity, assay/potency, isomer profile, and stability controls appropriate for a light/oxygen-sensitive fat-soluble vitamin ingredient.
Market RoleLarge domestic consumer and finished-supplement manufacturing market; import-dependent for MK-7 ingredient supply with some domestic formulation/standardization
Domestic RolePrimarily an input for U.S. dietary supplement manufacturing and brand owners; limited direct consumer purchase of bulk MK-7 ingredient
Specification
Physical Attributes- Usually supplied as a stabilized bulk ingredient (powder via adsorption/microencapsulation or oil-based concentrate/premix) designed for accurate low-dose blending
- Light/oxygen sensitivity is commonly considered in packaging and storage specifications
Compositional Metrics- Identity confirmation and assay/potency (e.g., chromatographic methods) are commonly specified
- Impurity profile controls may include residual solvents (if used in processing), heavy metals, and microbiological limits consistent with dietary supplement quality programs
Grades- Dietary supplement ingredient grade supplied with lot-level Certificate of Analysis (COA) and traceable test methods
Packaging- Sealed, light-protective bulk packaging with lot identification and storage conditions stated on labels/documents
Supply Chain
Value Chain- Ingredient production (often fermentation-derived) -> purification/standardization into powder or oil premix -> bulk packaging -> importer/broker -> U.S. contract manufacturer or brand owner -> finished dietary supplement packaging and distribution
Temperature- Avoid excessive heat exposure during storage and transport; storage conditions are typically set to preserve potency over shelf life
Atmosphere Control- Minimize oxygen and light exposure to reduce potency loss; packaging and headspace control may be used depending on format
Shelf Life- Potency retention over stated shelf life is a key quality attribute; stability data and retest/expiry dating are commonly requested by buyers

Risks
Regulatory Compliance HighIf MK-7 is treated as a New Dietary Ingredient (NDI) for the intended use and no adequate NDI notification exists, or if cGMP/specification controls are inadequate, FDA enforcement actions (including import detention/refusal, warning letters, or product holds at brand/manufacturer level) can disrupt or block trade into the U.S. market.Perform an NDI status assessment for the specific MK-7 product/use, maintain 21 CFR 111-compliant specifications and identity testing, and implement importer controls (e.g., supplier qualification and verification consistent with FDA import programs).
Food Safety MediumPotency variability, impurities, or contamination (e.g., residual solvents if applicable, heavy metals, microbiological issues) can trigger batch rejection by U.S. manufacturers/retailers and elevate regulatory scrutiny for finished supplements.Require a robust COA package with method references, conduct incoming verification testing, and use third-party certification/verification programs where commercially required.
Labeling And Claims MediumDownstream brand claims for supplements containing MK-7 can attract FDA/FTC attention if they drift into disease claims or otherwise misbrand the finished product, creating commercial discontinuation risk for ingredient demand.Align product positioning with DSHEA-compliant structure/function claims and maintain claim substantiation and compliant labeling review processes.
Standards- NSF/ANSI 173 (dietary supplements)
- USP Verified Mark (finished dietary supplements; buyer-driven quality signal)
FAQ
Which U.S. rules most directly affect MK-7 used in dietary supplements?MK-7 used as a dietary supplement ingredient is governed by the U.S. dietary supplement framework under DSHEA and by FDA’s dietary supplement current good manufacturing practice requirements in 21 CFR Part 111. Import processes can also involve FDA import requirements for foods (such as Prior Notice) alongside CBP entry procedures.
What documentation is typically most important for importing MK-7 into the United States for supplement manufacturing?At minimum, importers need standard CBP entry documentation and should be prepared to provide FDA Prior Notice confirmation where required for food imports. Commercially, U.S. buyers commonly expect a lot-specific Certificate of Analysis (COA) and specification/traceability documentation to support dietary supplement cGMP controls under 21 CFR Part 111.
Why do U.S. buyers often ask about third-party standards for supplements containing MK-7?Third-party programs such as NSF/ANSI 173 and USP’s dietary supplement verification offerings are used by some brands and retailers to signal quality and help manage contamination/adulteration risks, which can be especially important in the U.S. supplement market.
