Understanding the Fundamentals of MCTs
Medium-chain triglycerides (MCTs) are a type of fatty acid metabolized differently than long-chain fats. They are quickly sent to the liver and converted into ketones, serving as fuel for the brain and body. This metabolic pathway makes MCTs popular for ketogenic diets and those seeking enhanced performance. Common MCTs in supplements are C8 (Caprylic Acid) and C10 (Capric Acid), named for their carbon chain length.
C8: The Fast Fuel Source
C8 is known for its speed. It has the shortest chain length of common MCTs and is absorbed and converted into ketones efficiently.
Key Benefits of C8
- Rapid Ketone Production: C8 causes the quickest and most significant rise in blood ketones, ideal for fast ketosis or an immediate energy boost.
- Enhanced Cognitive Function: Ketones from C8 fuel the brain, providing clear mental energy and combating brain fog.
- Potent Antimicrobial Properties: C8 may have antibacterial effects, supporting a healthy gut microbiome.
Ideal for: Quick energy before workouts, improved mental focus, or achieving rapid ketosis on a strict keto diet.
C10: The Sustained Energy Provider
C10 has a slightly longer chain than C8 and is metabolized more slowly. This leads to a steadier, more sustained energy release.
Key Benefits of C10
- Sustained Energy: C10 provides a gradual energy release, avoiding sudden spikes and drops.
- Antifungal and Immune Support: C10 is known for its antifungal properties, effective against yeasts like Candida, which benefits gut health and supports the immune system.
Ideal for: Longer-lasting energy for endurance, improving gut health, or a milder introduction to MCTs.
Comparison: C8 vs. C10 MCT Oil
| Feature | C8 (Caprylic Acid) | C10 (Capric Acid) |
|---|---|---|
| Carbon Chain | 8 atoms | 10 atoms |
| Energy Conversion | Very Rapid | Moderately Rapid / Sustained |
| Ketone Production | Quick, High Peak | Steadier, Longer-lasting |
| Best For | Instant energy, focus, rapid ketosis | Sustained energy, endurance, gut health |
| Unique Benefits | Strong Antimicrobial | Strong Antifungal |
| Cost | Generally Higher | Generally Lower |
The Hybrid Approach: C8 and C10 Blends
Many MCT oils combine C8 and C10, often in a ratio like 60:40 or 70:30. These blends offer benefits from both, combining the rapid energy of C8 with the sustained energy and antifungal properties of C10. Blends are a balanced option for daily use and are often more cost-effective than pure C8 oils. Check the label for specific ratios when considering a blend.
How to Choose the Right MCT for You
The best choice depends on your goals. There isn't one universally "better" MCT.
- For maximum ketosis and mental clarity: Pure C8 is best for quick ketone production and a mental boost.
- For sustained energy and gut health: A pure C10 or a C8/C10 blend is great for longer energy and its antifungal benefits for the gut.
- For daily wellness and balance: A mixed C8/C10 blend offers a comprehensive approach with both fast and sustained energy and support for mental and gut health.
Start with a small dose (like a teaspoon) and gradually increase to avoid digestive issues. MCT oil mixes easily into coffee, smoothies, or salad dressings.

Conclusion: Finding Your Optimal MCT
Both C8 and C10 are beneficial MCTs with distinct advantages. C8 provides rapid energy and cognitive benefits by quickly converting to ketones, while C10 offers sustained energy and antifungal properties for gut health. A C8 and C10 blend is a practical choice for many, providing a range of benefits. The ideal MCT depends on your individual needs for energy, ketosis, and overall health.
