Caprylic acid came to prominence as a food additive thanks to Dr. William Crook, author on the famous book on internal ecology "The Yeast Connection". Today it is widely used to achieve a healthy microbial balance and as supporting substance to other effective additives, including for example acidophilus and FOS. Caprylic acid is also gaining widespread appeal among sportsmen who value it for its ability to deliver quick energy to the body. Caprylic acid is a medium-chain triglyceride (MCT), a type of lipid that is not dissolved in the gut but rather in the liver, similar to carbohydrates. As such, it provides fast energy - more than twice the quantity provided by glucose.
