Over 90% of nutrient absorption occurs in the small intestine, not the colon. The colon, or large intestine, plays a different but equally vital role in the digestive process, primarily focused on the final stages of waste processing.

Over 700 species of bacteria in the human colon produce significant amounts of vitamin K2, but the question of its absorption site has long been debated. This fat-soluble vitamin, vital for blood clotting and bone health, is primarily absorbed in the small intestine, yet research shows a passive diffusion process allows some bacterially synthesized vitamin K to be absorbed in the colon. Understanding this complex process is key to appreciating your microbiome's contribution to your overall nutrition.
