Gut microbiota also plays a crucial role in synthesizing vitamin B and vitamin K, as well as metabolizing <u>sterols and bile acids</u>. These bacteria act much like an endocrine system that regulates intestinal function with the use of short-chain fatty acids, as if they were hormones.
<u>Vitamin K</u><u> is important for</u><u> blood clotting</u><u>, while </u><u>vitamin B</u><u> intervenes in </u><u>cellular metabolism</u>.
