MCT oil vs coconut oil: C8, C10 and lauric acid explained

MCT oil is made by separating specific medium-chain fatty acids, usually caprylic acid (C8) and capric acid (C10), from coconut or palm kernel oil. Whole coconut oil contains these too, but its largest single fatty acid is lauric acid (C12), which behaves differently in digestion. So MCT oil is not simply "stronger coconut oil". It is a different mix.

Why the chain length matters

Fatty acids are named by the number of carbon atoms in their chain. Shorter chains are generally absorbed and processed differently from long-chain fats. Whether lauric acid should be counted as a medium-chain fat is a recurring point of disagreement, and it affects how marketing claims about coconut oil should be read.

What to check on a product

The C8 and C10 split, stated on the label or a certificate of analysis.
The source oil: coconut, palm kernel or a blend.
Third-party testing for contaminants.

Evidence status

Health effects claimed for MCT oil need human trial evidence and will be reviewed separately. This Rough Draft makes no health claim. Supplements are not approved by the FDA before sale.
