Caprylic acid (octanoic acid) is a medium-chain saturated fatty acid that occurs naturally in the milk of several mammals and in coconut and palm oils. It gained attention for its possible potential health benefits, including antimicrobial and anti-inflammatory properties, and is often used in treating yeast infections and skin conditions. In the context of diabetes research, caprylic acid has been studied as a potential marker of insulin resistance. It has been found in certain studies to be predictive of prediabetes, mainly when analyzed alongside other factors like body weight and blood sugar levels.
