Curated, not stocked.
Bulletproof built its brand on MCT science before the category became crowded, and this oil reflects that focus. It uses coconut-derived C8 and C10 — the fractions most studied for ketone conversion — without unnecessary additives. We recommend it for patients who want a reliable, unfussy fat source to support energy or a ketogenic protocol, and who need something that integrates easily into an existing morning routine.
About this product
MCT Oil
Bulletproof MCT Oil is a concentrated source of medium-chain triglycerides (MCTs) derived from coconut, providing C8 (caprylic acid) and C10 (capric acid) fatty acids. Unlike long-chain fats, MCTs are absorbed directly into the portal circulation and transported to the liver, where they are rapidly converted into usable energy rather than stored. C8 in particular is studied for its efficiency in producing ketones, which the brain and muscles can use as an alternative fuel to glucose.
This oil suits anyone following a low-carbohydrate or ketogenic diet, those managing energy levels across a demanding day, or people who simply want a fast-absorbing fat source without added flavour or sweetness. It blends easily into coffee, smoothies, or cooked food, making it straightforward to work into an existing routine without restructuring meals.
Bulletproof has built its reputation specifically around MCT research and application, and this product reflects that focus. The formulation uses coconut-sourced C8 and C10, the two MCT fractions most commonly cited in the literature on ketone production and cognitive fuel. It is a no-fuss, single-purpose product — one ingredient class, clearly sourced, doing one job well.

How to use
Add to coffee, smoothies, or food as desired. Start with a small amount and increase gradually — introducing MCT oil slowly helps your digestive system adjust. Check the packaging for the recommended daily amount.

Common questions
Frequently asked
What is the difference between C8 and C10 MCTs?
C8 (caprylic acid) is the shorter of the two chains and converts to ketones more efficiently in the liver. C10 (capric acid) is slightly longer and metabolises a little more slowly. Together, they provide a practical balance of fast fuel and sustained energy output.
Will this break a fast or disrupt ketosis?
MCT oil contains calories, so it does technically break a strict fast. However, because it promotes ketone production, many people using intermittent fasting or a ketogenic diet include it deliberately. Whether it fits your protocol depends on your specific goals — check with your clinician if unsure.
Why do some people experience digestive discomfort with MCT oil?
MCTs are absorbed quickly, and taking too much too soon can cause nausea or loose stools in some people. Starting with a small amount and building up gradually over a week or two usually resolves this.
Can I cook with this oil?
MCT oil has a relatively low smoke point compared to oils like coconut or avocado oil, so it is best added to food after cooking, or used in no-heat preparations like smoothies and coffee.
Is this suitable for a dairy-free diet?
The oil itself is derived from coconut, not dairy. That said, check the packaging for any allergen or cross-contamination information specific to this product before use.
