Let's take a look...The natural occurrence of medium-chain triglyceride (MCT) oil exists in coconut oil, palm kernel oil and other dairy products. The consumption of MCT oil leads to increased Peptide YY and leptin hormone production, which makes you feel full. Research shows that MCT oil consumption leads to better memory performance, enhanced thinking abilities and mental focus. Our digestive system receives a boost from MCT oil, because it creates a balanced gut microbiome and better digestion processes. People who experience digestive problems or have trouble absorbing fat-based nutrients, should consider using MCT oil as a dietary supplement.
