Key Points
- Bulk-buy 3-pack — three 946mL bottles at a discount versus buying separately
- 100% caprylic acid (C8) — the shortest of the medium-chain triglycerides, isolated to a single fatty acid
- Made from coconut oil — the C8 fraction is separated through fractional distillation
- Odorless and flavourless — blends into hot and cold drinks, dressings, and cooking without altering taste
- Ketogenic-friendly — suits low-carb and ketogenic dietary patterns; pure fat, zero carbohydrate
- Fits the Bulletproof Coffee recipe as the MCT oil component
What It Is
This is a 3-pack of Bulletproof Brain Octane Oil — a medium-chain triglyceride (MCT) oil containing only C8 (caprylic acid). Coconut oil naturally contains a mix of medium-chain fatty acids — C8 (~8%), C10 (~7%), C12 lauric acid (~48%), and other longer-chain fats. Bulletproof isolates the C8 fraction through fractional distillation, giving a product that is 100% C8 caprylic acid triglyceride.
Because it contains only C8 — not C10 or lauric acid — it’s a shorter, more concentrated version of what standard MCT oils provide. It has no colour, no odour, and no taste.
No added vitamins, no fillers, no preservatives. Each bottle contains one ingredient: caprylic acid MCT oil. If you use MCT oil regularly, this 3-pack is more economical than buying three single 946mL bottles separately.
Sourcing & Processing
Source: Coconut oil, from responsibly harvested coconuts.
Processing: The C8 caprylic acid fraction is separated from the rest of the coconut oil through fractional distillation (heat + pressure differentials, no chemical solvents).
What’s left out: Lauric acid (C12), C10 caprate, longer-chain saturated fats, and non-triglyceride components. This is not coconut oil — it’s the C8 fraction of coconut oil.

How to Use
Because it has no flavour or colour, Brain Octane blends easily into a wide range of foods and drinks:
- In coffee — as the MCT oil component of the Bulletproof Coffee recipe
- In smoothies — add 1 tablespoon per serve; blends without altering flavour
- In salad dressings — substitutes for other oils; whisks well with vinegar and mustard
- Drizzled on food — over steamed vegetables, soups, or fatty meats after cooking
- Cold uses — suitable for cold or lukewarm dishes; not recommended for high-heat frying
Start small. If you’re new to MCT oil, begin with 1 teaspoon (5mL) per day and increase gradually over a week or two. Taking too much too quickly is a common cause of digestive discomfort — MCTs are absorbed differently from other fats, and the gut may need time to adapt.
The Bulletproof Coffee Recipe
"Bulletproof Coffee" is the preparation method for which Brain Octane was originally created. It combines brewed coffee with grass-fed butter (or ghee) and MCT oil, blended to a creamy consistency.
Bulletproof Coffee Preparation
- Brew 2 cups of Bulletproof coffee using the method of your choice
- Combine with 2 tablespoons of unsalted grass-fed butter (or grass-fed ghee for a dairy-free option)
- Add 2 tablespoons of Brain Octane Oil (this product)
- Blend in a high-speed blender (or use an Aerolatte® frother) until a creamy head of foam forms
- Pour and drink while hot
Good to Know
Why buy a 3-pack?
The 3-pack is priced at a discount versus buying three individual 946mL bottles separately. It suits regular users who go through a bottle every 3–4 weeks (roughly one tablespoon per day), and reduces delivery cost per bottle. Also useful for households where more than one person uses MCT oil.
How is this different from coconut oil?
Coconut oil is roughly 62% medium-chain triglycerides mixed with longer-chain fats; only about 8% of it is C8 caprylic acid. Brain Octane isolates the C8 fraction only. It’s liquid at room temperature and flavourless, whereas coconut oil is solid below ~24°C and tastes distinctly of coconut.
How long will 3 bottles last?
At 1 tablespoon per day, roughly 6 months. At 2 tablespoons per day, roughly 3 months. Unopened bottles have a shelf life of about 2 years from manufacture; opened bottles should be used within 6–12 months for best quality.
Why does it get cloudy in the fridge?
MCT oil can thicken or cloud when cold. This is normal. Once returned to room temperature the oil clears and thins again. This does not affect the quality or shelf life.
I was so impressed with this oil. I bought three more that I share with my son.
It curbs the hunger feeling which allows me not to over eat.
I’m losing about a kilo per week Fully recommend this product
So far all good, headaches reduced.
I have been buying this MCT oil for years. It helps me function in my crazy lifestyle and I can’t do without it.
I love how by purchasing it through optimoz, you get a discount for the multiple purchases and it arrives pretty quickly
fantastic product, I use it daily
I’m using bulletproof Brain octane oil from optim oz now quite a long time. Quality of product, price and delivery is top notch. I highly recommend this product.
I use this every day so a three pack sets me up for a couple of months. I know that I’ve got what I need to super charge my coffee hit/s. Delivery was prompt, as usual, with excellent packaging. Thanks Optimoz, my go-to supplier for I think 7 years now, long time anyway. As the fastest, most efficient supplier Optimoz has set the bar high for competitors. No one I’ve tried yet even meets it let alone beats it.
I’ve started putting this MCT oil in my morning coffee and am loving it! It dissolves really well and doesn’t change the flavour of my coffee. Not only helping with my menopausal brain fog, it’s also helping me fast longer when needed. Great product!
I’ve used it for 7 years and find it excellent for my coffee. Together they curb my appetite so I extend my overnight fast by a few hours.
I run multiple businesses, so I need every advantage I can get. Adding Brain Octane to my Bulletproof coffee each morning gives me the mental clarity, focus, and sustained energy I rely on throughout the day. It also keeps me satisfied, making it easier to stick to OMAD (One Meal A Day) without distractions.
We add the oil to our coffee every day, and it’s a total game-changer! It mixes in so well, makes the coffee super smooth, and gives a nice clean energy boost that lasts. No weird jitters, just focus. Definitely a must-have for mornings :)
I’ve been using the brain octane for years. Goes in my daily shake, blended into coffee and 5ml in my nutrition drinks in long rides. Awesome product, flavourless and mixes easy. Best MCT oil in the market by far.
MCT Brain is part of my morning routine ...added to my AG1 along with D3 and Collegan...keeps my brain alert
I’ve been using the BULLETPROOF™ BRAIN OCTANE OIL 3 PACK, and I can definitely feel the difference in my focus and energy levels. On the days I forget to take it, I notice a dip in both, so it’s become a must for me. The 3-pack is great because it ensures I have enough stock to last, and it’s a good value for the price. Highly recommend for anyone looking to boost mental clarity and sustain energy throughout the day!
Good value for great product
A great Bulletproof product that has helped me start my day for 6 years! And great service and speedy delivery that Optimoz has always given.
I use brain octane oil in Bulletproof coffee and it enables me to get through the day with out needing to pause for a meal. The triple pack available from Optimoz works out to be the best value for money I have been able to find within Australia.
Wouldn’t be without Bulletproof Brian Octane Oil. I have it in a bulletproof coffee style drink every morning and it makes a noticeable difference to brain clarity and energy levels.
If you regularly use Brain Octane, buy the bundle for great value.
I had a problem with an item damaged in delivery and Optimoz were very quick and pleasant about arranging a replacement. Really excellent service.
No nasty reactions to this oil unlike cheaper brands. I use it on salads daily. Vital for my anti fungal diet.
Pure C8 MCT oil that is perfect to add to coffee and give your brain a great start to the day.
fast Absorbtion, great in coffee! love the energy!
I love the BulletProof Octanr Oul as it keeps me feeling full until lunch time. No need for breakfast if you use this product in your coffee. Love it. Thank you..

On the daily in my morning beverage
Buying 3x bulletproof brain octane is the way to go. Thanks optimoz!
I was surprised to receive the bottles in a very short amount of time. Very professional!
Helps jumpstart me for the day as much as anything can with narcolepsy. I definitely notice when I don’t have it.
I’ve been using Brain Octane Oil for few years. It is perfect oil to add on with my bulletproof coffee in the morning to freaking me up. Pure and transparent oil also giving energy for the day. I’m highly recommend this product.
My partner and I use this everyday in our bulletproof coffee. It helps me be sharp as a tack during the morning and makes fasting a breeze. The bulk pack helps us save money too. Thanks for the fast and easy ordering OptimOz!
