The Health Benefits of Medium Chain Triglycerides

What are MCTs?

Medium-chain triglycerides, also known as MCTs, are a type of fat that can be found in certain oils. They differ from long-chain triglycerides, which are found in many foods, in terms of their molecular structure and properties. MCTs contain fatty acids with a chain length of 6-12 carbon atoms, as opposed to 14-18 carbon atoms in long-chain fatty acids. The medium-chain fatty acids in MCTs are called caprylic acid (C8) and capric acid (C10). Coconut oil and palm kernel oil are naturally rich sources of MCTs.

How are MCTs digested and metabolized?

One unique feature of MCTs is that they are absorbed directly into the portal vein and transported to the liver, where they are rapidly converted into ketone bodies. This is different from long-chain triglycerides, which require bile acids and pancreatic enzymes for their breakdown and absorption and take much longer to be metabolized. Because MCTs do not require energy-intensive processing in the digestive tract, they provide quick energy and do not lead to fat storage. They also enhance the production and utilization of ketone bodies in the liver, which can be used as an alternative fuel source for tissues like brain, muscle and heart.

Potential health benefits of MCTs

Weight management

Studies show that MCTs may promote feelings of fullness and reduce appetite compared to other fats. They also tend to be thermogenic, meaning the body expends more calories converting them to energy. For this reason, MCTs have been shown to help decrease body weight and fat mass over time. Supplementing the diet with MCT oil could aid weight control and loss.

Heart health

Compared to long-chain triglycerides, medium chain triglycerides are less likely to be stored as fat in the body. They rather get used immediately by the liver as a quick source of energy. This makes them less associated with risks like high cholesterol and cardiovascular disease. Some research even found that MCTs may help reduce levels of total and LDL cholesterol in the blood. Maintaining healthy cholesterol levels reduces risk of heart attacks and strokes.

Brain health and function

When MCTs are converted to ketone bodies in the liver, these travel to the brain and act as an alternate source of fuel. Studies show that ketone body levels from MCTs can enhance cognitive function, brain metabolism and neural connectivity. This may benefit conditions like Alzheimer's disease and other forms of dementia. MCT supplementation is also linked to improved memory, concentration and overall brain health.

Antimicrobial properties

Capric acid, one of the main medium-chain fatty acids in MCTs, displays antimicrobial qualities. It has been found to effectively inhibit or kill pathogens like bacteria, viruses and fungi. This includes harmful bacteria like Staphylococcus aureus and pathogenic yeast such as Candida albicans. The anti-microbial properties of MCTs can potentially improve gut health and immunity.

Additional potential benefits

Some studies associate MCTs with promoting body fat loss specifically in the abdominal region when combined with exercise. They may also help manage conditions like metabolic syndrome, insulin resistance and diabetes due to their ability to increase insulin sensitivity. More research is still needed but early evidence links MCTs with anti-inflammatory and anticancer effects as well. Supplementing the diet with MCTs could offer various therapeutic advantages.

Safety and recommended intake of Medium Chain Triglycerides

When consumed in moderation, MCTs are generally regarded as safe for most people. However, initially ramping up intake too quickly could potentially cause gastrointestinal side effects like loose stools, cramps or bloating until the body adjusts. Starting with just 1 teaspoon of MCT oil per day and gradually increasing the amount prevents discomfort. For general health benefits, intakes of 2-4 tablespoons per day are commonly recommended, providing approximately 100 calories per serving. More can be consumed but exceeding 15mL/kg body weight daily is not usually advised. Consulting a healthcare provider is also a good idea before significantly altering intake or background diet. Pregnant or breastfeeding women may want to be cautious with amounts and check with their doctor as well. When used judiciously as part of a healthy lifestyle, MCTs can offer nutritional support.

In conclusion, medium chain triglycerides present several promising potential benefits for metabolism, heart health, brain function and immunity. Primarily found in coconut and palm kernel oils, MCTs are readily digested and converted to energy. Supplementing the diet with MCT oil could aid weight management and offer therapeutic effects. However, starting intake gradually and maintaining moderation is advised in order to experience benefits safely. More research continues to expand our understanding of MCTs. When properly incorporated, they could be a useful dietary adjunct.
