Vitamin K2
Vitamin K-2 can be found in egg yolks and dairy products. It aids in wound healing and blood clotting. For vegans who cannot eat eggs or dairy, fermented foods can be a good source of vitamin K2. These include plant-based kefir, vegan kimchi, unpasteurized kombucha, natto, and raw sauerkraut. It is not common for vegans to have a deficiency of vitamin K because bacteria in the gut would produce vitamin K-2 from vitamin K-1. Nevertheless, taking supplements, especially vegan probiotic supplements can aid the gut in processing vitamin K.[3]
