For dog owners, particularly those whose pets suffer from epilepsy, finding the right dietary supplements can be a game-changer. Medium-chain triglyceride (MCT) oil has emerged as a potent tool in managing epilepsy and supporting overall brain health in dogs. However, within the realm of MCT oils, two fatty acids stand out: C8 (caprylic acid) and C10 (capric acid). While both offer significant benefits, they differ in how they work and the specific advantages they provide. Understanding these differences can help you make the best choice for your dog’s needs.
Understanding MCT Oil: A Quick Overview
MCT oil is composed of medium-chain fatty acids, which are metabolised differently from the long-chain fatty acids found in most fats. When your dog consumes MCT oil, these medium-chain fatty acids are rapidly absorbed and transported to the liver, where they are converted into ketones. Ketones serve as an alternative energy source for the brain, particularly useful when glucose levels are low. This process is especially beneficial for dogs with epilepsy, as ketones help stabilise neuronal activity and reduce the likelihood of seizures.
C8 (Caprylic Acid): The Powerhouse for Immediate Brain Energy
How C8 Works in the Brain
C8 is often referred to as the "powerhouse" of MCTs because of its superior ability to produce ketones quickly. Once ingested, C8 is rapidly converted into ketones by the liver. These ketones can cross the blood-brain barrier, providing an almost immediate energy source for the brain. They are a corner stone for helping the brain’s production of GABA and as a regulator of brain activity, which in turn helps prevent the electrical disturbances that lead to seizures.
Scientific Insights on C8’s Effectiveness
Research has shown that C8 produces ketones more efficiently than any other MCT, including C10. For example, studies indicate that C8 can elevate blood ketone levels up to four times more than C10 or coconut oil. This rapid ketone production is not just about speed—it’s about ensuring that the brain has a steady and regulated supply of energy. In a dog with epilepsy, the brain’s ability to use glucose efficiently may be impaired, leading to energy deficits that make neurons more prone to excessive firing, which can trigger seizures. By providing an alternative energy source in the form of ketones, MCT oil helps to stabilise brain function, thereby reducing the likelihood of seizures.
The Cognitive Benefits of C8
Beyond seizure control, C8 has been associated with enhanced cognitive function. Ketones produced from C8 have neuroprotective properties that support brain health by reducing oxidative stress, improving mitochondrial function, and promoting cellular repair. In both animal studies and human trials, C8 has been linked to improvements in memory, focus, and overall mental clarity. For dogs, this could mean not only fewer seizures but also better cognitive performance, especially as they age.
Digestibility and Practical Considerations
Another advantage of C8 is its ease of digestion. Unlike long-chain fats that require bile for digestion, C8 is absorbed directly into the liver, minimising the risk of gastrointestinal discomfort. This makes C8 particularly suitable for dogs with sensitive stomachs or those prone to digestive issues.
C10 (Capric Acid): Sustained Energy and Neuroprotection
How C10 Supports Brain Health
While C10 does not produce ketones as quickly or to the same extent as C8, it has its own set of benefits that make it valuable, especially when used in combination with C8.
Potential Neuroprotective Properties
Recent research suggests that C10 has the ability to inhibit AMPA receptors in the brain. AMPA receptors are involved in excitatory neurotransmission, and overactivation of these receptors can lead to seizures. By blocking these receptors, C10 helps reduce neuronal excitability, offering an additional layer of protection against seizures that is independent of ketone production.
Mitochondrial Function and Long-Term Benefits
C10 is believed to support mitochondrial function, which is crucial for maintaining healthy brain cells. Mitochondria are the powerhouses of the cell, responsible for producing the energy that neurons need to function properly. By enhancing mitochondrial efficiency, C10 helps ensure that neurons have the energy they need to operate effectively, which can contribute to long-term brain health and resilience against neurodegenerative conditions.
Combination vs. Pure C8: A Nuanced Choice
No Direct Comparisons in Research
It’s important to note that while both C8 and C10 have been studied extensively, there are currently no direct comparisons between using pure C8 versus a combination of C8 and C10 in any animal model, no less specifically for dogs with epilepsy. This lack of comparative research means that the choice between pure C8 and a combination with C10 is not definitive or clear cut. The good news is that whether choosing pure C8 or a combination of C8 and C10, both versions have extensive scientific research supporting their ability to help in epilepsy management.
The Case for Combining C8 and C10
Combining C8 and C10 offers a balanced approach. While C8 delivers ketones in greater quantities at greater speeds, C10 can supports long-term brain health through its unique chemical reactions that give it its neuroprotective properties.
The Case for Pure C8
For dog owners focused on immediate seizure control and cognitive enhancement, pure C8 MCT oil may be the most effective option. The rapid and efficient ketone production from C8 provides the brain with a quick and steady energy source that help stabilize neuronal activity. Ketones not only fuel the brain but also have neuroprotective properties. They reduce oxidative stress, support mitochondrial function, and encourage the repair and growth of brain cells. Additionally, the cognitive benefits of C8, supported by its neuroprotective effects, make it a compelling choice for dogs that need immediate brain support. The significant increase in ketone production caused by pure C8 makes it a compelling choice for owners managing canine epilepsy.

Choosing between pure C8 and a combination of C8 and C10 MCT oil seems like a challenging choice; however, remember that both options are great! The important thing is to find a high quality, pure, organic MCT oil that meets the highest standards of testing. As with any supplement, please consult with your veterinarian before introducing MCT oil into your dog’s diet. Your vet can provide personalised guidance based on your dog’s specific condition and health history.
Whether you opt for pure C8, a combination with C10, or another approach, understanding the differences between these MCT oils will empower you to make the best decision for your dog’s long-term health.
