What exactly is MCT oil? And what makes it so special? Simply Keto MCT Oil with Bulletproof Coffee and Coconut Simply Keto MCT is a particularly effective extract of coconut oil. The two fatty acids were extracted (C8 and C10), which the body can absorb and use particularly quickly. These two particular fatty acids are called caprylic acid (C-8) and capric acid (C-10). It is processed into ketone bodies in the liver and is therefore a real booster for ketosis, as ketone bodies serve as an energy source in the ketogenic diet. Coconut oil only contains a small proportion of these fatty acids. Coconut oil consists largely of other fatty acids, which are among the medium-chain fatty acids, but behave like long-chain fatty acids. Therefore, they cannot be split so quickly. That is why coconut oil has a different effect than MCT oil. For Simply Keto MCT oil, we completely dispense with caproic acid (C6).
