MCTs

Medium-Chain Triglyceride
The fatty acids found in MCT oil are called medium-chain triglycerides. The names of the medium-chain fatty acids (and the corresponding number of carbons) found in MCTs are caprylic acid (C8) and capric acid (C10). Like all triglycerides (fats and oils), MCTs are composed of a glycerol backbone and three fatty acids, hence the name triglyceride; in the case of MCTs, 2 or 3 of the fatty acid chains attached to glycerol are medium chain in length. Medium-Chain Triglycerides contain glycerol esters of 8 & 10 carbons (95%) with negligible C12 (Lauric Acid) component, less than 5% fatty acid  esters of glycerol.

MCTs passively diffuse from the GI tract to the portal system (longer fatty acids are absorbed into the lymphatic system) without requirement for modification like long-chain fatty acids or very-long-chain fatty acids. In addition, MCTs do not require bile salts for digestion. Patients that have malnutrition or malabsorption syndromes are treated with MCTs because they do not require energy for absorption, utilization, or storage.Rich sources for commercial extraction of the beneficial MCTs include palm kernel oil and coconut oil. Another source of MCT's is camphor tree drupes.


Dietary / Performance Relevance
Some studies have shown that MCTs can help in the process of excess calorie burning, and thus weight loss. MCTs are also seen as promoting fat oxidation and reduced food intake. There has also been interest in MCTs from endurance athletes and the bodybuilding community. While there seem to be health benefits from MCTs again MCT's lack the cholesterol raising Lauric, Myristic, and Palmitic Acids, a link to improved exercise performance is weak.Dairy fat is a major source of myristic acid, and palm oil is especially rich in palmitic acid. Virgin and non-Virgin Coconut oils remain the richest source of Lauric Acid.


Medical Uses
Medium-chain triglycerides are generally considered a good biologically inert source of energy that the human body finds reasonably easy to metabolize. They have potentially beneficial attributes in protein metabolism but may be contraindicated in some situations due to their tendency to induce ketogenesis and metabolic acidosis.
Due to their ability to be absorbed rapidly by the body, medium-chain triglycerides have found use in the treatment of a variety of malabsorption ailments. MCT supplementation with a low-fat diet has been described as the cornerstone of treatment for primary intestinal lymphangiectasia (Waldmann's disease). MCTs are an ingredient in parenteral nutritional emulsions. Studies have also shown promising results for neurodegenerative disorders (e.g. Alzheimer's and Parkinson's disease) and epilepsy through the use of ketogenic dieting.
