Research suggests that MCT oil may support cognitive function through its ability to raise blood ketone levels, which can serve as an alternative energy source for the brain, with small studies in both humans and animals pointing toward improvements in memory, problem-solving, and related cognitive measures. The available evidence includes a small randomized controlled trial in people with mild cognitive impairment, a crossover RCT in dogs with epilepsy, dietary intervention studies in senior dogs with cognitive dysfunction, and a study examining MCT oil combined with glucose in healthy young adults, with most findings directionally supportive though a few show mixed or mechanistically complex results. Studies indicate that the cognitive benefits observed may be linked to ketone production, shifts in neurotransmitter balance such as increased GABA, and alterations in fatty acid and amino acid metabolism, though the precise mechanisms remain an active area of investigation. Importantly, much of the animal research cannot be directly extrapolated to humans, the human trials are very small and preliminary, and larger well-controlled studies in human populations are needed before firm conclusions can be drawn.
