Capric Acid (C10 MCT)
Capric acid (C10:0) is a medium-chain fatty acid that rapidly converts to ketones in the liver via beta-oxidation, providing immediate energy for brain and muscle tissue. This saturated fatty acid also exhibits antimicrobial properties by disrupting pathogen cell membranes through lipid bilayer destabilization.

Origin & History
Capric Acid, or C10 MCT, is a medium-chain triglyceride found in coconut oil and palm kernel oil. It is extracted through a process called fractionation.
Historical & Cultural Context
Traditionally used in tropical regions for its energy-boosting and antimicrobial properties.
Health Benefits
- Supports energy metabolism by converting to ketones, providing a steady energy source for both brain and body. This can enhance endurance during physical activities. - May have antimicrobial and antifungal properties by disrupting the lipid membranes of pathogens, thus supporting immune health. - Supports cognitive function by supplying an alternative energy source for the brain, improving focus and mental clarity. - Enhances weight management by promoting fat oxidation, which can lead to reduced body fat. - Supports digestive health by maintaining a balanced gut microbiome, which can improve overall digestion. - May improve exercise performance by providing a quick energy source, reducing perceived exertion during workouts. - Supports skin health by maintaining hydration and elasticity, leading to a more youthful appearance.
How It Works
Capric acid bypasses normal fatty acid metabolism by traveling directly to the liver via the portal circulation, where it undergoes rapid beta-oxidation by medium-chain acyl-CoA dehydrogenase to produce ketone bodies (beta-hydroxybutyrate and acetoacetate). These ketones cross the blood-brain barrier via monocarboxylate transporters and serve as alternative fuel sources for neurons and muscle cells. The antimicrobial activity occurs through insertion into pathogen lipid membranes, causing membrane fluidity changes and cell lysis.
Scientific Research
Research, including some RCTs, has investigated its effects on metabolism and cognitive function. In vitro studies suggest antimicrobial benefits.
Clinical Summary
Human studies on capric acid are limited, with most research focusing on mixed MCT supplements rather than isolated C10. A small study of 20 athletes showed 15% increased ketone levels within 30 minutes of consuming 10g capric acid compared to long-chain fats. In vitro antimicrobial studies demonstrate effectiveness against Candida albicans and Helicobacter pylori at concentrations of 50-100 μg/mL. However, well-controlled clinical trials specifically examining capric acid's therapeutic effects in humans are lacking, with most evidence derived from animal models and cell culture studies.
Nutritional Profile
- Contains 10 carbon atoms in its chain. - Provides approximately 9 calories per gram. - Quickly metabolized by the liver for energy.
Preparation & Dosage
Typically consumed in amounts of 1-3 tablespoons per day. Start with small doses to assess tolerance. Consult a healthcare provider before use.
Synergy & Pairings
Caprylic Acid, Lauric Acid, Omega-3
Safety & Interactions
Capric acid is generally recognized as safe (GRAS) by the FDA when consumed in typical dietary amounts (1-5g daily). Higher doses (>10g) may cause gastrointestinal upset including nausea, cramping, and diarrhea due to rapid gastric emptying. No significant drug interactions have been reported, though it may enhance ketone production in individuals taking SGLT2 inhibitors or following ketogenic diets. Pregnant and breastfeeding women should consult healthcare providers before supplementation, as safety data in these populations is insufficient.
