MCTs (medium-chain triglycerides) are fats that are absorbed and metabolised differently from most dietary fats. They’re found naturally in foods such as coconut oil and palm kernel oil, and are also sold as MCT oil supplements.
For brain health, the main interest in MCTs is that they can be rapidly converted by the liver into ketones, which the brain can use as an alternative fuel source to glucose.
Potential effects include:
• Providing an alternative energy source for the brain: This may be particularly relevant when glucose metabolism in the brain is impaired, such as in aging or some neurodegenerative conditions.
• Supporting cognitive function: Some studies have found improvements in memory, attention, or mental clarity in certain groups, especially older adults with mild cognitive impairment.
• Possible benefits in Alzheimer’s disease research: Researchers have investigated MCTs because reduced brain glucose utilisation is common in Alzheimer’s disease. Some studies show temporary cognitive benefits from increasing ketone availability.
MCTs are not known to directly “repair” the brain. Their primary mechanism appears to be improving energy availability through ketone production, with possible secondary effects on inflammation and cellular signalling.
