Capric Acid (C10)
Medium-chain fatty acid rapidly converted to ketones for energy and antimicrobial defense.
Also known as: Decanoic Acid • C10:0 • Medium-Chain Fatty Acid C10
Overview
Capric acid (decanoic acid) is a 10-carbon medium-chain fatty acid found in coconut oil, palm kernel oil, and dairy fat. It is rapidly absorbed and converted to ketones in the liver, providing quick energy. Capric acid also has notable antimicrobial and antifungal properties, particularly against Candida species.
Key Benefits
Rapid Ketone Production
Converted to ketones faster than long-chain fats, providing quick fuel for brain and muscles.
Antifungal Properties
Highly effective against Candida albicans and other fungal pathogens, disrupting their cell membranes.
Seizure Management
Research suggests C10 has direct anti-seizure properties independent of ketosis through AMPA receptor inhibition.
Gut Barrier Support
Supports intestinal epithelial integrity and may reduce gut inflammation.
Dosage & How to Take
5-15g daily as part of MCT oil or isolated C10 supplement. Start with lower doses and increase gradually.
| Purpose | Dose | Notes |
|---|---|---|
| General energy | 5-10g daily | As part of MCT oil blend |
| Ketogenic support | 10-15g daily | Split into 2-3 doses |
| Antifungal support | 5-10g daily | Consistent daily use |
Best Time to Take
Morning or before exercise for energy; can be taken any time
With or Without Food
Can be taken alone or added to food/beverages
