The benefits of MCT oil are numerous, ranging from gastrointestinal health to metabolic health, to better heart and brain function. It is a staple of the ketogenic diet, which emphasizes high-fat and low-carb. MCT oil is generally well tolerated and absorbed because it’s a medium-chain triglyceride (fat), as opposed to a long-chain triglyceride (LCT). Among its many health offerings, increased satiety and weight loss are proven benefits of adding it to your diet. MCT oil is a supplement and should be taken in small doses to assess tolerance before increasing the amount.
