C8 vs. C10 – Explaining Different MCT Fatty Acids

MCT oils consist of medium chain triglycerides, which differ in their chain length. The two most important fatty acids in MCT oils are C8 (caprylic acid) and C10 (capric acid). They differ in digestion, energy production, and everyday use.

What are C8 and C10?

• C8 – Caprylic Acid

  • Eight carbon atoms

  • Very quickly metabolized

  • Directly converted into ketones in the liver – fast energy for muscles and brain

• C10 – Capric Acid

  • Ten carbon atoms

  • Also medium-chain, metabolized slightly slower than C8

  • Provides steady energy, supports ketosis, but not as quickly as C8

Differences at a Glance

Benefits for Athletes and Keto Enthusiasts

• C8: Immediate energy before training or for mental performance, optimal for ketogenic diet.

• C10: Stable energy over a longer period, e.g., for longer workouts or as a snack supplement.

• Combination: Many MCT oils contain both fatty acids to combine fast and sustained energy.

Application Tips

• Dosage: 1-2 tablespoons daily, gradually increase.

• Preparation: Stir into smoothies, shakes or coffee – do not heat.

• Sport: Before or during training for energy, after training in combination with protein is possible.

Conclusion

C8 provides immediate energy and ketones, while C10 ensures steady, sustained energy. Combining both fatty acids can achieve maximum flexibility for training, ketogenic diet, or everyday life.
