What are short-chain fatty acids (SCFAs) and why do they matter?

Short-chain fatty acids (SCFAs) are produced when prebiotic fiber is fermented by gut bacteria. They are the primary fuel source for the cells lining your colon, support gut barrier integrity, contribute to immune function and are linked to sustained energy and mental clarity.

You cannot produce them without adequate prebiotic fiber - and the average modern diet delivers less than half of what the body needs.
