MCT Ketone Energy provides 14 grams of MCT per tablespoon to support energy metabolism and production. Also known as octanoic acid, caprylic acid is an eight-carbon MCT naturally found in coconut and palm kernel oil. Because it is rapidly absorbed, transported directly to the liver, and readily crosses the mitochondrial membrane to undergo Knoop oxidation, caprylic acid is an efficient fuel source, readily assimilated by fatty tissue. Acute ingestion of 10 g of caprylic acid is also known to increase the formation of ketone bodies, which are normally produced by the liver when glucose availability is low, such as during fasting or intense exercise. In addition to providing energy for tissues like the heart and muscle, ketone bodies become the brain's primary secondary energy source when glucose availability decreases. A clinical trial found caprylic acid to be the most ketonic MCT compared to coconut oil, capric acid (C10:0), or a combination of oils. MCTs have also been suggested to support energy production and performance during exercise by regulating mitochondrial function and carbohydrate utilization, and may contribute to negative energy balance by increasing energy expenditure.
