Medium-chain triglycerides are converted to ketones by the liver, providing a direct source of energy for the brain, regardless of the individual's fasting or fed state. Utilizing FDA-approved medical foods, like various ketone products on the market, can potentially enhance cognitive function. Anecdotal evidence, such as Dr. Mary Newport's experience with her husband who had Alzheimer's disease, suggests significant cognitive improvement with the use of medium-chain triglycerides. While coconut oil was initially used, products with higher concentrations of key fatty acids like caprylic acid (C8) are now preferred for their potent ketone precursor properties. However, excessive consumption of medium-chain triglycerides may lead to diarrhea, highlighting the importance of moderation in intake.
