Brain Fuel (MCT oil) - high levels of C8, C10, C12


Brain Fuel’s Medium-chain triglycerides (MCT) are obtained 100% from non-GMO organic coconuts. Coconuts have the richest source of MCTs on earth. Medium-chain fatty acids consists of caprylic (C8:0), capric (C10:0) and lauric (C12:0) acids. These medium-chain fats in coconut oil are similar to fats in mother's milk and have similar nutraceutical effects. 

MCTs differ from other dietary fats (i.e. long-chain fatty acids) in the way they are metabolized. MCTs are easier to process based on their shorter chain lengths. The advantage of having a shorter chain is that these triglycerides can bypass the need to be broken down by bile, which allows them to go straight to the liver for processing. The liver is where the fat in your dog’s body is converted directly into ketones that the body and brain use for fuel.

The brain usually relies on sugar to fuel its functions. According to studies, for those who suffer from diseases that inhibit them from using sugar correctly to fuel normal brain functions, MCT oil can help to block the memory loss receptor activated by the disease and Ketones may serve as a brain-boosting alternative fuel source. MCT oil is well known to assist with the brain development of puppies, provide a natural brain stimulant and improve cognitive function for aging and senior dogs. 

The MCTs found in coconut oil have been shown to hinder the growth of strains of yeast and bacteria found in the mouth and on the skin. 

Brain Fuel is best for animals with specific energy needs, such as animals recovering from sickness, senior pets and animals with low energy. It will give them the vitality and energy to be active and happy dogs. 


Some additional benefits include:

  1. Brain food for puppies during training & brain development

  2. Brain fuel for senior dogs helping to improve cognitive function – enabling them to be more alert, have higher energy and vitality

  3. Assists to increase metabolism – so great for over-weight dogs

  4. Improves skin conditions

  5. Improves gut health

  6. Improves the immune system – kills disease creating bacteria

VetActiv8’s MCT oil has high levels for Medium Chain Triglycerides, due to the unique extraction process, and source of coconuts.

The Effects of a Ketogenic Medium-Chain Triglyceride Diet on the Feces in Dogs With Idiopathic Epilepsy


The primary aim of this study was to evaluate changes to the fecal microbiome and lipidome of dogs recruited on the MCT-KD trial (a trial of MCT diet as a treatment for dogs with idiopathic epilepsy)

Efficacy of medium chain triglyceride oil dietary supplementation in reducing seizure frequency in dogs with idiopathic epilepsy without cluster seizures: a non-blinded, prospective clinical trial

Veterinary Record 10.1136/vr.105410 on 12 June 2020

This study demonstrates the use of a diet enriched with MCTs as an adjunct to ASD treatment may have some antiseizure properties for dogs diagnosed with IE, as demonstrated in previous studies.

Dietary supplementation with medium-chain TAG has long-lasting cognition-enhancing effects in aged dogs


British Journal of Nutrition (2010), 103, 1746–1754

The present study shows that supplementation of MCT in ageing dogs can significantly increase blood ketone body concentrations under fed conditions and improve age-related decline in cognitive function by providing an alternative source of brain energy in old healthy dogs. The MCT-containing diet had no adverse effects on CBC and blood chemistry.

Lack of toxicity by medium chain triglycerides (MCT) in canines during a 90-day feeding study

Food and Chemical Toxicology 47 (2009) 35–39

Based on the findings from this 91-day MCT feeding study, there are no indications of toxicological effects in dogs fed up to 15% MCT in the diet

Cody was getting stiff joints and over time he needed to get injections for his arthritis as it got to a point where he would hop on 3 legs as he couldn't walk on one of them. We thought we would give VetActiv8 Joint Health a try as we wanted a more natural approach if there was one available.
He has been on it for about 2 months, and we have seen such an improvement as he now enjoys his walks and no longer struggled going up steps.
