MCT stands for medium-chain triglycerides, which are a type of fat that is easier to digest than long-chain triglycerides found in most of the fats we eat. MCT oil is a supplement made from coconut or palm kernel oil through a process called fractionation, which separates the MCT from the original oil and concentrates it. MCT oil is usually taken as a dietary supplement and can be used for a quick energy source, weight loss, appetite control, extra energy for exercise, inflammation, and to help with problems taking in fat or nutrients. MCTs are also used for involuntary weight loss called cachexia or wasting syndrome, obesity, seizures, athletic performance, Alzheimers disease, and many other conditions, but there is no good scientific evidence to support these other uses.

MCTs are saturated fats and are high in calories, so it is recommended to consume MCT oil as part of your total amount of fat intake and not as a replacement for other healthy fats. MCT oil can cause certain chemicals called ketones to build up in the body, which can be a problem for people with diabetes. MCTs are processed by the liver, so they can cause serious problems in people with liver disease.

While MCT oil has gained popularity in recent years, more research is needed to discover if MCT oil can help with any of the conditions it is used for.
