Bulletproof® Brain Octane® Oil — 3-Pack

Three full-size 946mL bottles of 100% pure caprylic acid (C8) medium-chain triglyceride oil packaged together for committed daily users and multi-person households. The same Bulletproof Brain Octane Oil sold individually — bundled at a per-bottle discount.

Derived exclusively from non-GMO coconuts. Triple-distilled using only water, heat and pressure. No palm oil. No lauric acid. No additives. Flavourless and odourless. Suitable for ketogenic, paleo, low-carb and intermittent fasting dietary patterns. Vegan. Gluten-free. Shelf-stable.

Why the 3-Pack?

The 3-pack is the most economical format of Brain Octane® Oil in the Optimoz catalogue. It's designed for buyers who are already using Brain Octane® Oil regularly and want to stock up at a lower per-bottle cost.

Format Single 946mL Bottle 3-Pack (this product)
Total volume 946mL 2,838mL (2.84L)
Effective per-bottle cost $74.95 $67.45 ($202.37 ÷ 3)
Per-bottle saving $7.50 per bottle
Typical duration at 1 tbsp/day ~2 months ~6 months
Typical duration at 2 tbsp/day ~1 month ~3 months

Shelf-life note: Brain Octane® Oil is shelf-stable and does not require refrigeration. Unopened bottles store well in a cool, dry place away from direct sunlight. At typical consumption rates (1 teaspoon to 1 tablespoon per day), three bottles will not expire before use.

First time trying Brain Octane® Oil? We'd suggest starting with the smaller 473mL bottle or the 90mL travel size before committing to a 3-pack. MCT oils can cause temporary digestive discomfort for new users until the digestive system adjusts — the smaller formats let you test tolerance first.

Who Buys the 3-Pack?

  • Established daily users — people who've finished a first bottle and want to lower their per-bottle cost going forward
  • Multi-person households — couples or families where more than one person uses the oil regularly, so the three bottles are consumed faster
  • Bulletproof Coffee enthusiasts — daily morning routine users who go through a bottle every 4–8 weeks
  • Small businesses — cafes, gyms, wellness practices — businesses serving Bulletproof-style coffee or offering it to clients
  • Bulk-buy preference — buyers who prefer to order less frequently and stock up

What It Is

Bulletproof® Brain Octane® Oil is a refined dietary oil consisting of 100% caprylic acid triglycerides (the C8 medium-chain fatty acid) isolated from coconut oil.

Coconut oil naturally contains a mixture of saturated fatty acids of different carbon-chain lengths. The four primary medium-chain fatty acids in coconut oil are:

  • C6 (caproic acid) — small amount, has a distinctive odour
  • C8 (caprylic acid) — this product is 100% C8
  • C10 (capric acid) — not present in this product
  • C12 (lauric acid) — not present in this product

Brain Octane® Oil isolates only the C8 fraction through a triple distillation process using only water, heat and pressure — no chemical solvents (no hexane), no additives.

About Medium-Chain Triglycerides

Medium-chain triglycerides (MCTs) are a category of saturated fatty acid distinguished by their carbon-chain length. Long-chain triglycerides (LCTs, the most common dietary fats) have 13+ carbon atoms; medium-chain triglycerides have 6–12 carbons; short-chain triglycerides have fewer than 6.

The medium-chain length affects how the fatty acid is processed by the digestive system. MCTs are commonly used in ketogenic and low-carb dietary patterns, as well as in clinical nutrition formulations.

Brain Octane® Oil vs Bulletproof® MCT Oil

Bulletproof produces two distinct MCT oil products with different compositional profiles:

Fatty Acid Composition Brain Octane® Oil (this product) Bulletproof® MCT Oil
C6 (Caproic Acid) None None
C8 (Caprylic Acid) 100% ~60%
C10 (Capric Acid) None ~40%
C12 (Lauric Acid) None None

The two products are produced by the same brand using similar refining processes — the difference is purely in the carbon-chain composition. Brain Octane® isolates the C8 fraction exclusively; the regular MCT Oil includes both C8 and C10. Brain Octane® commands a higher price point because C8 is the less abundant of the two medium-chain fractions in coconut oil, making it more processing-intensive to isolate.

Why 100% Coconut Sourcing?

Many commercial MCT oils on the market are sourced from palm kernel oil rather than coconut oil. Palm kernel oil also contains C8 and C10 medium-chain triglycerides, but the palm industry is associated with significant environmental and ethical concerns — deforestation, habitat loss, and labour-rights issues in major production regions.

Bulletproof® Brain Octane® Oil is sourced exclusively from non-GMO coconuts, with no palm oil at any stage of production.

Directions for Use

Start with 1 teaspoon (5mL) daily and gradually increase to 1 tablespoon (15mL) per serve as your digestive system adjusts.

Suggested uses: Blend into hot or cold beverages (coffee, smoothies, shakes), drizzle over salads, mix into salad dressings, or add to soups and other recipes. Pairs naturally with the Bulletproof® Coffee recipe.

Cooking: Suitable for cooking up to 160°C (320°F). Do not use for high-heat frying.

Storage of unopened bottles: Keep in a cool, dry place away from direct sunlight. The oil is shelf-stable and does not require refrigeration. Once a bottle is opened, continue storing in the same conditions — refrigeration is not required even after opening.

Important: Use to add to or partially replace other oils in meals and drinks — not as a complete replacement. Consuming large amounts on an empty stomach may cause digestive discomfort (loose stools, stomach upset). Build up gradually.

Good to Know

Will three bottles expire before I use them?

At typical consumption (1 teaspoon to 1 tablespoon per day per person), three bottles last approximately 6 months for a single user, or proportionally less for multi-person households. Brain Octane® Oil is shelf-stable and does not go rancid quickly when stored properly — unopened bottles are well within shelf life for normal consumption timeframes. Check the printed best-before date on each bottle for the manufacturer's stated shelf life.

Does it taste like coconut?

No. The refining process removes the coconut flavour and aroma. Brain Octane® Oil is flavourless and odourless, so it blends into beverages and recipes without altering the taste.

Is it the same as coconut oil?

No. Coconut oil is approximately 50% lauric acid (C12), 6–7% capric acid (C10), 7–8% caprylic acid (C8), with the remainder being other saturated and unsaturated fats. Brain Octane® Oil isolates only the C8 fraction, removing the lauric acid and other components entirely.

Why does the bottle say to start with a small amount?

MCTs are processed by the digestive system more rapidly than long-chain fats. Consuming a large amount before the digestive system has adjusted — particularly on an empty stomach — can cause temporary digestive discomfort (loose stools, mild stomach upset). Building up gradually over 1–2 weeks allows the system to adapt. If you haven't used Brain Octane® Oil before, consider starting with the smaller 473mL bottle or 90mL travel size first to test tolerance.

Can I cook with it?

Yes, but only at low to moderate temperatures (up to 160°C / 320°F). Above this temperature the oil begins to break down. For high-heat cooking, use a different oil (avocado oil, ghee, or coconut oil are common alternatives).

Does it go solid in cold weather?

No. Unlike coconut oil (which solidifies at temperatures below about 24°C), Brain Octane® Oil remains liquid at room temperature and even in cool conditions. This is because the lauric acid — the component of coconut oil with the highest melting point — has been removed.

How is this different from Bulletproof MCT Oil?

Bulletproof MCT Oil contains a blend of C8 (caprylic acid) and C10 (capric acid) at approximately 60/40 ratio. Brain Octane® Oil is 100% C8 with no C10. The C8-C10 blend is more economical to produce and is a common choice for those new to MCT supplementation. The pure C8 version is preferred by some users who want a single-component oil. Read the detailed comparison article.

Are the three bottles the same product as the single bottle listing?

Yes. Each of the three bottles in this pack is identical to the 946mL single bottle product — same formulation, same packaging, same manufacturer batch process. The 3-pack is simply three of these bottles bundled together at a per-bottle discount.
