All MCT Oil Supplements Compared
The split that matters is C8 versus a C8/C10 blend. Caprylic acid (C8) converts to ketones fastest and is what most ketogenic diets are actually referring to, while cheaper blends dilute it with C10 and sometimes lauric acid. Serving sizes here are unusually consistent at around 14–15 g, so cost per day is a fair comparison in this category — check the C8 percentage on the label, since it is the variable the price tracks.

How these 6 MCT Oil products were ranked
