MCT stands for Medium-chain triglycerides and, from Wiki, “MCTs passively diffuse from the GI tract to the portal system (longer fatty acids are absorbed into the lymphatic system) without requirement for modification like long-chain fatty acids or very-long-chain fatty acids. In addition, MCTs do not require bile salts for digestion.”
Coconut oil itself does not have the same MCT quantities, which need to be extracted and refined.
