Description
A pure C8 (caprylic acid) triglyceride, the medium-chain triglyceride most associated with rapid ketone production and ketogenic-diet supplementation. Produced by esterification of glycerol with caprylic acid fractionated from coconut or palm kernel oil.
Colorless to very pale yellow clear oil. Liquid at room temperature with low viscosity. Mild characteristic odor and a slightly oily mouthfeel.
We supply food-grade and pharmaceutical-grade MCT C8 from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include MCT C8 95% min (the standard premium grade), MCT C8 98% min (ultra-pure for high-end keto applications), and pharmaceutical-grade material meeting USP and EP monographs. Non-GMO and sustainable-palm certified grades are available on request.
Bulk and reduced-MOQ shipments. Batch-level COA covering fatty acid profile, acid and peroxide values, moisture, heavy metals, and microbiology.
Introduction
Medium-chain triglycerides comprise saturated fatty acids with chain lengths of 6 to 12 carbons, of which caprylic (C8) and capric (C10) are the most commercially significant. Pure C8 is the fraction most rapidly metabolized to ketone bodies in the liver.
Production starts from coconut or palm kernel oil, which is hydrolyzed to free fatty acids and glycerol. The C8 fraction is separated by fractional distillation, then re-esterified with food-grade glycerol to produce caprylic triglyceride. Final purification yields material at 95 to 98 percent C8 with the balance comprising adjacent fractions.
MCT C8 is recognized as safe in major food regulatory systems and listed in USP, EP, and JP pharmacopoeias as a lipid-based excipient.
The compound's distinctive metabolic property is its rapid hepatic conversion to beta-hydroxybutyrate and acetoacetate, the ketone bodies that fuel the ketogenic-diet effect. Among MCTs, C8 produces the highest ketone yield per gram of intake.
Oxidative stability is excellent due to the fully saturated structure, supporting long shelf life and broad processing compatibility including high-temperature applications.
