Medium-chain triglycerides (MCTs) are fatty acids—not amino acids—most commonly derived from coconut oil, with caprylic acid (C8) and capric acid (C10) being the principal types used in supplements. Unlike longer-chain fats, MCTs are rapidly absorbed and transported to the liver, where they can be converted into ketones, an alternative energy source for the brain and muscles. Research suggests that MCT supplementation may support cognitive function, particularly in situations where glucose utilization is impaired, and some studies indicate potential benefits for energy levels, exercise endurance, and weight management through increased satiety and modest effects on metabolic rate. While findings are promising across these areas, results vary depending on the specific MCT form, dose, and individual factors, so the evidence continues to evolve.
