Medium-chain triglycerides (MCTs) are fats composed of medium-length fatty acid chains, typically extracted from coconut oil or palm kernel oil. They are absorbed and metabolized quickly by the body, providing a rapid source of energy that bypasses typical fat digestion.
MCTs are popular in the fitness world for supporting endurance, mental clarity, and ketogenic metabolism. Unlike long-chain fats, MCTs are rapidly transported to the liver and converted into ketones, making them beneficial for low-carb or ketogenic athletes.
Their fast absorption profile makes MCTs a practical energy alternative to carbs during prolonged activity, especially for endurance sports.
