Recent testing of consumer vitamin K2 products sold on major online platforms in Poland reveals significant opportunities for enhanced stability and purity – areas in which Balchem is leading with proven solutions.
Driving quality advancement
Following on prior studies conducted in Germany and the US, Poland was selected for this latest round of testing for its dynamic landscape and high consumer expectations.
The country has a fast-growing supplement market, with a projected annual growth rate of 8.51% (CAGR 2025–2029).
Balchem collaborated with a certified third-party laboratory to analyse more than 20 K2 products available on e-commerce platforms, focusing on key quality parameters such as vitamin K2 MK-7 assay and isomeric purity.
Reinforcing the company’s dedication to support the industry through advanced testing and formulation excellence, the findings point to a valuable opportunity for manufacturers and vitamin K2 suppliers to work together to raise quality standards and create solutions that can truly support consumers’ health.
Raising the bar for K2 quality
“Vitamin K2 is a powerful nutrient and its full potential depends on ingredient quality and stability. For instance, products with high levels of all-trans MK-7 vitamin K2 isomers are better positioned to support consumers’ health."
"That’s because all-trans isomers have elevated carboxylative activity, enabling the activation of vitamin K-dependent proteins – a crucial step in delivering the health benefits consumers expect from vitamin K2,” explains Lena Leder, PhD, Nutrition Science Manager at Balchem Human Nutrition & Health.
“With Balchem’s market research, we wish to reinforce the importance of rigorous testing to achieve formulation excellence. And we’re committed to this standard too with our K2VITAL ingredient: a patented, typically 99.7% all-trans K2 MK-7 ingredient."
"With more than 400 stability tests conducted, K2VITAL consistently demonstrates exceptional purity and superior performance. This level of quality helps brands deliver reliable, science-backed products to consumers.”
Innovation for stability: K2VITAL DELTA
To further support the industry globally, Balchem developed K2VITAL DELTA, the world’s only patented microencapsulated vitamin K2 preparation designed for stability in complex formulations.
Its double-coated beadlet technology preserves K2’s potency and stability in mineral-rich environments, ensuring long-lasting efficacy and shelf-life.
“Our mission is to empower supplement brands with the tools and ingredients they need to succeed,” Leder adds.
“By investing in innovation and transparency, we’re helping the market evolve together ... in Poland and beyond.”
