C8 (Caprylic Acid) Oil

Bioavailability: Very High. Best for: Maximum ketone production and cognitive benefits — the most efficient MCT chain length.

C8 + C10 Blend

Bioavailability: High. Best for: Balance of rapid ketone production (C8) and sustained energy (C10) — most popular format.

MCT Powder

Bioavailability: High. Best for: Coffee blending, travel convenience, and those with sensitive stomachs — acacia fiber carrier slows absorption.

Liquid MCT Oil (Full Spectrum)

Bioavailability: Moderate. Best for: Budget option — contains C8, C10, and C12 (lauric acid); less ketogenic than pure C8.
