There are 173 published clinical (human) studies on K2 according to a Pubmed search. Many of them are sponsored and published by academia bodies, not private companies.
The results of these studies are copyrighted, however quoting small sections that are directly relevant to something one is writing about is acceptable under Fair Use, as long as one provides an appropriate citation. Summarizing and quoting from a medical article in a news article (Commentary, Criticism, “transformative” purpose) is considered a fair use according to this source. All human clinical studies were designed and performed on Menaquinone-7 chemical compound which does not differ in terms of bioavailability or safety profile regardless if obtained through organic synthesis or biochemistry (industrial fermentation). Vitamin K2 offered in the market differs only in terms of purity offered and presentation oil, powder, microcapsule. We encourage all our clients to produce educational content based on the available study results and fair use policy. In case of advertising of a specific brand, use of third-party study results is prohibited.
