K2 is produced by humans from K1.
Humans also produce creatine, choline and taurine, but for these three there is convincing evidence that the internal production is not sufficient, so for vegans it is beneficial to take supplements with them.
It is likely that the internal production of K2 is also insufficient, but I have not seen yet any conclusive research results about this, because it is very difficult to control all confounding factors.
Even if it is not certain that this is needed, it is prudent for vegans to also take vitamin K2 supplements, along with the other substances known to be missing or insufficient in vegetables (vitamins B12, D3 and K2; DHA and EPA; creatine, choline and taurine; iodine, selenium, calcium and sodium).
