Tricaprylin Alone Increases Plasma Ketone Response More Than Coconut Oil Or Other Medium Chain Triglycerides An Acute Crossover Study In Healthy Adults

This study compared different types of medium-chain triglyceride (MCT) oils to see which ones best increase ketones in the blood. Ketones are an alternative fuel source that your brain can use instead of glucose, and they're produced naturally during fasting or when following very low-carb diets. Researchers gave nine healthy adults different oil supplements and measured their ketone levels over eight hours.

The researchers tested coconut oil, standard MCT oil blends, pure C8 oil (caprylic acid), pure C10 oil (capric acid), and mixtures of these oils. Each participant tried all the different oils on separate days, taking two 20-milliliter doses mixed with milk - one with breakfast and another at noon without lunch.

Pure C8 oil was by far the most effective at raising ketone levels, producing ketone concentrations that were more than eight times higher than the control group who received no oil. Coconut oil, despite being popular for ketogenic purposes, only achieved about 25% of the ketone response that pure C8 oil produced. The C8 oil maintained elevated ketone levels throughout the entire eight-hour testing period.

These findings suggest that if someone wants to increase their ketone levels for potential cognitive or metabolic benefits, pure C8 oil would be more effective than coconut oil or mixed MCT products. At VALIA Health, this research helps inform personalized nutrition strategies for patients interested in ketogenic approaches for brain health, metabolic optimization, or longevity protocols.
