Medium-chain triglyceride (MCT) oil, derived from coconut and palm oil, has emerged as a popular health supplement. Its unique properties offer a variety of potential advantages, including boosting brain function, optimizing digestive health, and supporting epilepsy management. Additionally, research suggests that MCT oil may play a role in preventing or treating Alzheimer’s disease. In this article, we will explore the diverse benefits of MCT oil, how to take it, address safety concerns, potential side effects, and its effectiveness for epilepsy management.

Boost Brain Function:

MCT oil has shown promise in enhancing cognitive function, particularly in individuals with mild cognitive impairment and Alzheimer’s disease. By increasing ketone levels in the brain, MCT oil provides an alternative energy source to glucose . One placebo-controlled study found that MCT oil supplementation improved cognitive performance in elderly individuals with mild cognitive impairment . Moreover, its potential to prevent or treat Alzheimer’s disease is attributed to the ability of ketones to aid brain cell fueling when glucose metabolism is impaired.

Optimizing Digestive Health:

In addition to its brain-boosting capabilities, MCT oil has been found to improve digestive health by enhancing the gut microbiome. It serves as a source of energy for beneficial gut bacteria, promoting the growth of Lactobacillus and Bifidobacterium strains while inhibiting harmful bacteria (5). Studies have shown that MCT oil supplementation can lead to an increase in beneficial gut bacteria, resulting in improved digestive health and a reduction in symptoms of gastrointestinal disorders.

Optimizing Digestive Health

Epilepsy Management:

The ketogenic diet, which often includes MCT oil, has demonstrated success in managing epilepsy. MCT oil’s ability to increase ketone levels plays a vital role in this treatment approach. A study published in The Lancet Neurology showed that a ketogenic diet, including MCT oil, significantly reduced seizures in children with drug-resistant epilepsy. MCT oil’s inclusion in the ketogenic diet offers a potential adjunctive therapy for epilepsy management.

How to Take MCT Oil:

To incorporate MCT oil into your diet, consider adding it to smoothies, coffee, or salad dressings. Start with small doses and gradually increase intake to minimize digestive discomfort. For personalized guidance on dosage and integration, consult a healthcare professional or registered dietitian.

How to Take MCT Oil

Is MCT Oil Safe?

MCT oil is generally safe for most individuals when consumed in moderation (7). However, it’s crucial to consult a healthcare professional before using MCT oil, particularly if you have underlying medical conditions or are taking specific medications.

Can You Take Too Much MCT Oil?

While MCT oil is generally well-tolerated, excessive consumption can cause gastrointestinal issues such as diarrhea, nausea, and abdominal cramps. Adhering to recommended dosage guidelines and monitoring individual tolerability is important.

Side Effects of MCT Oil:

Common side effects include digestive discomfort, especially when consumed on an empty stomach. Gradually increasing the dose and consuming it with food can help mitigate these effects.
Allergic reactions to MCT oil are rare but can occur in individuals with coconut allergies.


MCT oil offers a range of potential benefits for brain function, digestive health, and epilepsy management. Its ability to enhance cognitive function, support a healthy gut microbiome, and aid in epilepsy management through increased ketone production is promising. Nevertheless, it is essential to consult healthcare professionals, follow appropriate dosage guidelines, and be aware of potential side effects to maximize the benefits of MCT oil.
