Bulletproof Brain Octane Oil Review: Is It Reliable and Quick Source of Energy?

If you’re a fan of Joe Rogan, you know he recommends Bulletproof Brain Octane Oil.

Bulletproof Logo

Even if you’re not a JR fan, bulletproof coffee is almost like a cult, so it’s impossible not to have heard about it.

And guess what the main ingredient in it is. Apart from coffee, of course.

So, is Bulletproof Brain Octane Oil really all that bulletproof?

It claims that this MCT oil is 18 times more powerful than coconut oil. And we all know how coconut oil is being presented as a miracle food.

Supposedly, it is the panacea you’ve been waiting for against your fat stores, sluggishness, brittle hair, and pimple-scattered face.

Let’s see how much truth there is in all that.

What is Bulletproof Brain Octane Oil?

This product is a reliable and quick source of energy because it’s a top-grade MCT oil.

Bulletproof Octane Oil

This MCT oil can assist your ketogenic diet, but can also put you fairly quickly into ketosis according to many positive reviews on the internet.

It provides energy for your body as well as for your brain; it assists in weight loss and helps your body burn through the fat stores.

This unique supplement from Bulletproof is said to be 18 times more effective than coconut oil if you’re to believe the manufacturers.

While it is a trustworthy company that backs all its products with thorough research, BOO is supported by several professionals too.


What Are the Ingredients? Nutrition Facts!

The main ingredient in Braine Octane Oil is MCTs. These medium-chain triglycerides are fatty acids, which have a medium-length sequence of carbon atoms.

Supplement FactsIf you’re on a keto diet, you know that your body needs to use fat for fuel. That means it has to break down fatty acids into ketones, which it uses for energy.

The longer the carbon chain on a fatty acid’s molecular structure, the harder it is to break. Unfortunately, most westerners eat long-chain fatty acids.

Bulletproof Brain Octane Oil Contains 100% C8 Medium-Chain Triglycerides.

These fatty acids contain just eight carbon atoms (hence C8), and they’re the easiest to break down in your body. That’s also why this product is called “Octane” oil.

Other MCT oils and powders on the market aren’t entirely made from C8. Most good MCT supplements are a mix of C8 and C10, while others include C12 in their composition.

C10 (Capric Acid) and C12 (Lauric acid) are more difficult to burn than C8 (Caprylic acid).

Let’s look at the nutrition facts too.

One Serving of Brain Octane Oil Includes:

  • 130 calories
  • 14g C8 MCTs aka 14g total fat (22% DRV) aka 14g saturated fat (70% DRV)

According to these nutritional facts, one low-calorie serving gets you most of the healthy fats you need per day.

You can either purchase the 16 ounces or the 32 ounces bottle, confident that you’re getting all the energy you need.

c8 & c10

Bonus: the C8 MCTs are derived from coconut oil. Coconut oil is a sustainable ingredient, unlike palm oil which is extracted from palm trees.

Palm trees only grow in the jungle, and cutting them down affects the rainforest and the climate, whereas coconut trees can grow unhindered in many artificial reservations.

Extra-bonus: Brain Octane Oil doesn’t have any fillers, additives, toxic chemicals, or trans-fats.

Even though this product is more expensive than other MCT oils, its price is a reflection of its quality.

How to Use: Instructions

Check out the label, and you’ll see there are several ways in which you can use this MCT Oil:

  • Gulp down a fool tablespoon of it, like it was medicine. Some people can pull this off and get all the fats and energy they need for the day.
  • Pour it into your coffee for instant energy without those pesky jitters.
  • Add it to your recipes. From salad dressings to sauces, smoothies, teas, or shakes, it is easy to mix.
  • Use it for baking or cooking, but remember not to heat your oven over 320°F, because that’s its burning temperature.

How Much Brain Octane Oil Can You Have Per Day?

The maximum recommended dosage is three tablespoons. Any more than that and you might experience bad GI distress.

Three TablespoonsKeep in mind that this dosage isn’t recommended in the long term, as going over your DRV of saturated fats can lead to serious health issues.

If you’re a keto newbie, it’s best not to start with a full tablespoon either.

Take half a teaspoon at first and watch for side effects and increase your dosage slowly.

Main Benefits and Side Effects

Bulletproof Brain Octane Oil has various benefits which we’ll discuss below, such as:

  • It gives a quick energy boost to your brain because your body transforms it fast into ketones. As opposed to glucose, ketones can’t be stored as fat, so they convert into energy for your brain.
  • You have more stamina because C8 is the easiest MCT to digest, so it’s an efficient type of fuel.
  • One serving has 14g of healthy fats and 130 calories. The high intake of fat curbs your hunger, and therefore it keeps you full for longer. As one serving is very low-calorie, this MCT oil can help you lose weight and stay full at the same time.
  • You will experience no sugar crashes and cravings because BOO is made entirely from C8 healthy fats, with no added artificial ingredients. As such, your body will benefit from a clean, sustained source of energy, unlike the energy you get from processed sugar.

There are other documented benefits of C8 to take into account, such as:

  • C8 extracted from coconut oil is a good remedy for skin and hair problems. If you have brittle hair and acne, coconut oil is a known homeopathic cure.
  • Caprylic acid boasts anti-inflammatory properties, meaning it can treat various illnesses.
  • C8 is a worthy weapon against some dangerous pathogens. As such, C8 can protect your good gut bacteria against all sorts of infection and help you get through your keto flu symptoms quickly.
  • C8 lowers your bad cholesterol levels and increases your good cholesterol levels. This is important if you’re following a high-fat diet such as keto.
  • Medium-chain triglycerides increase your metabolism so you can lose weight faster without experiencing those famous weight loss plateaus usually associated with fad diets.
  • MCTs have been proven to prevent muscle mass loss when they’re associated with intense workout routines.

Can You Enjoy These Benefits if You’re Not on Keto?

Let’s face it: keto is hard to keep up with, and so many people steer clear of it.

Benefits of SupplementNo judgment. Luckily, Bulletproof Brain Octane Oil isn’t an exclusive product for keto-ers.

Even if you’re following a carb-based diet, you can still enjoy the benefits.

Just make sure you’re eating quality carbs from vegetables, not processed carbs from sugar-filled cakes and cookies.

Here’s what Brain Octane Oil can do for you if you’re not on keto:

  • It can give you more energy in a fasted state, for instance, with your morning coffee after you haven’t eaten all night.
  • It can reduce tremors.
  • It can help you lose fat weight when combined with a challenging exercise routine.
  • It promotes digestive health because of its anti-inflammatory and anti-microbial properties.
  • It can keep you feeling fuller for longer.

However, the fewer carbs you consume in your diet, the more BOO can do for you.

What are Brain Octane Oil’s Side Effects?

This supplement is safe, especially for people who are used with MCTs and keto diets.

If you want to minimize potential negative effects, respect the recommended dose on the packets and consult your doctor before taking this supplement, especially if you have:

  • Hypotension
  • Liver disease
  • MCAD

There are no documented side effects for breastfeeding or pregnant women, but it should be a safe supplement considering that breast milk contains MCTs too.

Side Effects of Bulletproof

Check this info with your lactation consultant because every mother and child has different nutritional needs.

Most common reviews of side effects include:

  • Diarrhea
  • Dizziness
  • Frequent urination
  • Stomach cramps
  • Tiredness
  • Vertigo

Does Brain Octane Oil Help With Weight Loss?

Yes. Brain Octane Oil Helps with weight loss because:

  • It’s nutritious and curbs your hunger thanks to its high saturated fat content.
  • It’s a good meal replacement thanks to its low-calorie content.
  • It helps you burn through your fat stores because it’s high in MCTs.

BUT (yes, there’s a but):

  • One serving contains 130 calories. A serving is a good meal replacement or snack, but you must stick under your maximum caloric intake to lose weight.
  • One serving contains 70% of the recommended saturated fat intake. These MCTs are transformed into energy, so you should use that energy to work out or generally be more active.

Brain Octane Oil vs. MCT Oil

Vs MCT Oil

Brain Octane Oil is an MCT oil too because it contains MCTs. However, there are major differences between Brain Octane Oil and MCT Oil, even though the Reddit community might not agree.

Brain Octane Oil Contains Up to Five Times as Much C8 as Other Products

It is made 100% from C8 Caprylic Acid. Good, but regular and more affordable MCT oils contain about 60% C8 and 40% C10. Some cheaper MCT oils go as low as 20% C8.

We’ve said this before: C8 is the fastest source of energy because it has the shortest carbon sequence from all the MCTs.

Brain Octane Oil Contains no C12

Other MCT Oils might also include C12 in the mix, the MCT with the longest chain of carbon atoms, so it’s almost like a long-chain fatty acid.

Although C12 Lauric acid has proven antimicrobial properties as well as mental health properties, it takes longer to metabolize it. So MCT oils with C12 don’t give you a huge energy boost.

Better Extraction Process

While BOO is expeller-pressed by using a huge amount of pressure, cheaper MCT oils can use cheap, dangerous chemical solvents like hexane for the job.

Better Purifying Process

Brain Octane Oil is refined and purified with water, heat, and pressure, which are all-natural tools. Instead, cheap MCT oils use chemical accelerants which are dangerous for your health.

Top Sourcing

As well as other quality MCT oils, are extracted entirely from coconuts. Cheap MCT oils and powders use palm kernels, which are not sustainable and eco-friendly.

Top Manufacturing

It is made in the USA, while other MCT oils are made overseas, in factories and facilities you have little info about.


Some MCT oils arrive in leaky packets, which are hard to drink from, while others come in bottles with a very wide mouths. It is packaged in a versatile, easy-to-use bottle that doesn’t spill when you drink from it.

Brain Octane Oil vs. XCT Oil

Vs XCT Oil

XCT Oil is a marketing term invented by Bulletproof to make their Bulletproof Brain Octane Oil stand apart from other products, which use a combination of C8 and C10.

There are two traps for regular people:

  • It’s making you believe that Brain Octane Oil is the only MCT oil on the market with a 100% C8 composition, which is not the case (see Perfect Keto MCT Oil).
  • It makes you believe that products that use C8 and C10 are not real MCT oils.

The differences between Brain Octane Oil and “XCT” oil are based on the fact that Brain Octane is 100% C8, whereas the other oils have up to 40% C10. As such:

  • It gives you a bigger energy boost.
  • It is better for mental clarity and focus.
  • It is better for burning fat stores quickly and weight management because C8 is metabolized faster than a mix of C8 and C10.

There are several other differences, especially if you buy an “XCT” oil from a low-quality brand:

  • Dangerous chemicals in the extraction and purifying process
  • Not an eco-friendly sourcing
  • Iffy manufacturing factories

But again, Bulletproof can compete with Perfect Keto “XCT” oil any time. And it might actually lose. I’ll explain why below.

Does It Really Work?

That’s the question everybody’s been waiting for, and the answer is yes.

On every website, you’ll see happy reviewers that swear Brain Octane Oil did wonder for them. These people confirm:

  • Their morning coffee tastes extraordinary.
  • They get a big boost of energy, with no jitters, but rather mental clarity.
  • They have more stamina.
  • They can raise their ketone levels quickly, especially if they take an exogenous ketone supplement based on BHB salts too.

Where To Buy

The best places to buy are the company’s website and Amazon, for some good deals and fast shipping.

Where To Buy Supplement

Walmart, Target, and GNC also retail this product, but Amazon is the cheapest place to get it, whether you order a 16 oz. or 32 oz. pack.

Does Brain Octane Oil Go Bad?

You might be wondering whether Brain Octane oil goes bad. Well, the truth is that there are some conditions that can affect the quality of Brain Octane oil. That includes an overabundance of phthalates, which can be found in most plastic bottles of makeup. Although many people enjoy the signature flavor of Brain Octane oil, there are some caveats to taking it. If you think Brain Octane oil is going to give you an excessive amount of greasiness, then you might want to swap it out for virgin olive oil.

If you’re concerned about the safety of getting it from Amazon, there’s actually some evidence to suggest that you’re fine. According to Cornell University, there are a lot of people who get oil poisoning after taking it. But on the flip side, there are also a lot of people who say.

Does MCT Oil Burn Belly Fat?

The main issue with octane c8 MCT Oil is that it does not really burn belly fat, but rather your liver. Your liver is the body’s largest fat-burning organ, and MCT oil is ingested as an incredibly concentrated form of medium-chain triglycerides (MCTs). Medium-chain triglycerides have been proven to be the body’s preferred energy source. However, there is more to fat-burning than burning a primary fat source.

First, MCTs increase circulating levels of beta-hydroxybutyrate, a metabolite associated with the burning of visceral fat and a side effect of MCTs, and that increases by 50% when the pure c8 MCT is ingested. If you remember, the fat-burning process starts in your stomach. What MCT oil is doing is increasing beta-hydroxybutyrate levels in the liver.

Has Anyone Lost Weight With MCT Oil?

Could MCT oil or liquid coconut oil be the missing piece to the weight loss puzzle? This is an important question. It’s a “have I lost weight” question. Yes. Many people claim they have lost weight. One company now offers a very large number of user results, with up to 70% of users reporting a 6lb weight loss and 1lb fat loss in as little as 12 days. Who wouldn’t want to buy this? Except… I can’t seem to find any news articles or reports which report MCT oil users actually lost weight. I’ve searched a lot.

A quick search shows that no news articles or reports have been published. Of course, some of you have published some articles on this. For example, here are some articles. However, the comments are really interesting. It seems that all these stories are being written by those who have a vested interest in a product (like weight loss).

Frequently Asked Questions

Is Brain Octane Oil Healthy?

Brain Octane Oil, also known as medium-chain triglyceride (MCT) oil, is often promoted as a health supplement with various claimed benefits. However, its impact on health must be evaluated based on scientific evidence.

MCT oil, including Brain Octane Oil, is a concentrated source of medium-chain fatty acids, specifically caprylic acid (C8). These fatty acids are metabolized differently than long-chain fatty acids, being rapidly absorbed and transported directly to the liver for energy production. This efficient metabolism is thought to provide quick energy and potential cognitive benefits.

While some studies suggest that MCT oil may increase ketone production and promote weight loss, the evidence is limited and inconsistent. Additionally, MCT oil’s effect on cognitive function is still being investigated, with some preliminary studies showing modest improvements in certain cognitive tasks.

Brain Octane Oil, being a highly purified form of MCT oil, is claimed to be even more potent and easily absorbed. However, scientific studies specifically evaluating Brain Octane Oil are scarce, making it difficult to draw definitive conclusions about its unique benefits.

It is important to note that Brain Octane Oil is a highly concentrated source of calories, providing 9 calories per gram, compared to 4 calories per gram from carbohydrates or protein. Excessive intake of any oil, including Brain Octane Oil, can lead to weight gain if not balanced with an appropriate calorie intake.

As with any dietary supplement, it is recommended to consult with a healthcare professional before incorporating Brain Octane Oil or any other MCT oil into your diet. They can provide personalized guidance based on your specific health goals and circumstances.

What’s the Most Unhealthy Oil?

One of the most unhealthy oils commonly consumed is partially hydrogenated oil, also known as trans fat. Trans fats are created through a process called hydrogenation, which converts liquid vegetable oils into solid fats to improve their stability and shelf life. Trans fats have been extensively studied and are associated with numerous adverse health effects.

Scientific evidence overwhelmingly shows that trans fats increase the risk of heart disease by raising bad cholesterol levels (LDL cholesterol) while simultaneously reducing good cholesterol levels (HDL cholesterol). They also promote inflammation and impair the function of blood vessels, leading to an increased risk of cardiovascular problems.

Consuming trans fats is also linked to a higher risk of developing type 2 diabetes, stroke, and certain types of cancer. Additionally, trans fats have been found to negatively affect cognitive function and increase the likelihood of developing neurodegenerative diseases.

Due to the significant health risks associated with trans fats, many countries have implemented regulations to limit their use in food products. It is important to read food labels carefully and avoid products that contain partially hydrogenated oils or trans fats to protect your health. Opting for healthier alternatives like olive oil, avocado oil, or coconut oil is recommended for cooking and food preparation.

Is Brain Octane Oil the Same as Coconut Oil?

Brain Octane Oil and coconut oil, while both derived from coconuts, are distinct products with differences in their composition and intended uses. Brain Octane Oil is a specific form of medium-chain triglyceride (MCT) oil, a type of fatty acid derived from coconut oil. However, the key distinction lies in the composition of MCTs.

Coconut oil contains a mixture of MCTs, including caprylic acid (C8), capric acid (C10), lauric acid (C12), and others. Brain Octane Oil, on the other hand, is specifically enriched with a higher concentration of caprylic acid, known for its rapid absorption and conversion into ketones—a crucial energy source for the brain.

Caprylic acid, a C8 MCT, undergoes a more efficient metabolic process compared to the longer-chain MCTs found in coconut oil. The liver quickly converts caprylic acid into ketones, providing a rapid and sustained energy source for both the brain and body. This is particularly relevant for individuals following ketogenic diets, where the goal is to enhance ketone production for energy.

In contrast, coconut oil contains a higher percentage of lauric acid, a C12 MCT. While lauric acid does have some health benefits, it is metabolized differently and less efficiently than caprylic acid. The conversion of lauric acid into ketones is slower, making Brain Octane Oil a more concentrated and effective source of ketones.

It’s worth noting that the choice between Brain Octane Oil and coconut oil depends on individual health goals. Brain Octane Oil is often favored for its rapid ketone production, making it suitable for those seeking cognitive benefits, increased energy, or aiming to maintain a ketogenic state. Coconut oil, with its diverse MCT profile, may be preferred for culinary purposes and general health benefits.

In summary, while both Brain Octane Oil and coconut oil originate from coconuts, they differ in their MCT composition. Brain Octane Oil is a more refined product, specifically enriched with caprylic acid, offering a targeted and efficient source of energy, particularly beneficial for those pursuing ketogenic or cognitive performance goals.

Final Conclusion

In this review of Bulletproof Brain Octane Oil, we analyzed it from all possible sides.

This supplement works as advertised because it’s a clean supplement, made entirely with C8 Caprylic Acid, which has documented benefits on your energy, mental clarity, and stamina.

But, if you recall, I mentioned that Brain Octane Oil might lose the battle with Perfect Keto.

Perfect Keto is another trustworthy, reputable brand in the world of keto supplements.

Perfect Keto MCT oils can be found in various forms: 100% C8, a mix of C8 and C10, in a bottle or capsules.


Capsules are very convenient, especially if you’re on the go, though these are more difficult to use in your recipes.

So why did I say that Perfect Keto MCT Oil is better?

Even though Perfect Keto doesn’t have anything on Bulletproof when it comes to purity of ingredients and processing, it’s more convenient because:

  • You can buy it in capsules.
  • You can order MCT oil powder.
  • Although Brain Octane oil doesn’t taste bad, Perfect Keto MCT Oil is the very definition of tasteless.
