16 Aug 2024 --- Over two-thirds of vitamin K2 supplements purchased in the US on a major e-commerce platform “fail to meet label claims due to low quality or purity,” according to research by Balchem and natural product testing laboratory Alkemist Labs. The companies caution that these quality issues compromise consumer well-being, diminish trust and harm the credibility of the supplement industry. Balchem contracted Alkemist Labs to test 38 vitamin K2 products in several formats and formulations. Of these samples, 71% fell short of the established quality benchmarks regarding K2 content in MK-7 (menaquinone-7) or isomeric purity.
