Vitamin K is primarily produced by bacteria in the gut microbiome of humans and other animals. Additionally, green leafy vegetables, such as spinach and kale, are rich sources of dietary vitamin K, specifically vitamin K1 (phylloquinone). Vitamin K2 (menaquinone) is found in fermented foods and animal products. Overall, both microbial synthesis and dietary intake contribute to the body's vitamin K levels.
