Which consequence results from disrupted colonic bacterial balance?

💡 Explanation

Reduced colonic bacteria impair carbohydrate fermentation. Because microbial vitamin K synthesis depends on fermentation, a disrupted microbiome leads to deficiency. Therefore, reduced bacteria cause lower vitamin K synthesis, rather than impacts to unrelated processes.
