What is Medium Chain Triglycerides (mcts)?

Medium chain triglycerides (MCTs) are partially man-made fats. The name refers to the way the carbon atoms are arranged in their chemical structure. MCTs are generally made by processing coconut and palm kernel oils in the laboratory. Usual dietary fats, by comparison, are long-chain triglycerides. People use MCTs as medicine.

MCTs are used along with usual medications for treating food absorption disorders including diarrhea, steatorrhea (fat indigestion), celiac disease, liver disease, and digestion problems due to partial surgical removal of the stomach (gastrectomy) or the intestine (short bowel syndrome).

MCTs are also used for "milky urine" (chyluria) and a rare lung condition called chylothorax. Other uses include treatment of gallbladder disease, AIDS, cystic fibrosis, Alzheimer's disease, and seizures in children.

Athletes sometimes use MCTs for nutritional support during training, as well as for decreasing body fat and increasing lean muscle mass.

MCTs are sometimes used as a source of fat in total parenteral nutrition (TPN). In TPN, all food is delivered intravenously (by IV). This type of feeding is necessary in people whose gastrointestinal (GI) tract is no longer working.

Intravenous MCTs are also given to prevent muscle breakdown in critically ill patients.

Possibly Effective for...

  • Certain types of seizures in children.
  • Preventing muscle breakdown in critically ill patients, when given intravenously (by IV). MCTs can provide calories in critically ill patients, but don't seem to offer any advantages over normal dietary fats (long chain triglycerides).

Possibly Ineffective for...

Insufficient Evidence to Rate Effectiveness for...

  • Alzheimer's disease. There is interest in using MCTs to treat Alzheimer's disease because MCTs might provide extra energy to the brain and might also protect the brain against damage from beta-amyloid protein plaques. These plaques are the structures that form in Alzheimer's disease and cause symptoms. Some research shows that a specific MCT product (AC-1202) does not significantly improve learning, memory and information processing (cognitive thinking) in people with mild to moderate Alzheimer's disease, except in people with a particular genetic make-up (change in the APOE4 gene). In the people with the APEO4 gene change, a single dose of the MCT product seems to improve cognitive thinking skills.
  • Chylothorax (a rare lung disorder). Taking MCTs by mouth or intravenously (by IV) might prevent malnutrition and a weakened ability to fight infection in children and adults with chylothorax.
  • Nutritional support of athletic training.
  • Decreasing body fat and increasing lean muscle.
  • Improving the absorption of calcium and magnesium.
  • Other conditions.
More evidence is needed to rate the effectiveness of MCTs for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
