Medium Chain Triglycerides (MCT Oil) have dramatically gained in popularity in Australia, in part thanks to Bulletproof, but primarily because as a population we have begun to shift our understanding of what constitutes healthy fats. With a better understanding of metabolic health in concert with increased popularity of low-carb style keto diets, MCTs now play a role in meeting daily nutritional needs.
MCTs are a subset of saturated fatty acids that, when used appropriately, have unique biological effects ranging from enhanced cognitive performance to accelerated weight loss. MCTs can be found incoconut and palm oil, dairy products, Bulletproof MCT oil and Bulletproof Brain Octane Oil. Note that Bulletproof MCT oils are 100% derived from coconut oil. Some other brands may still source from palm oil which is destructive to rainforests inhabited by wildlife including Orangutans. Conservation efforts can be supported by nut buying palm oil containing products and through charities like Orangutan Foundation International.
Brain Octane Oil is 100% pure C8 (caprylic acid) and the most ketogenic of MCTs. Bulletproof MCT Oil is a blend of C8 & C10. This makes it a more economical option. Both products are manufactured only in the USA.
Bulletproof MCT Oil purity means that it does not contain C6 which is more prone to causing digestive upsets. It also does not contain C12 (lauric acid) which acts more like a long-chain-fatty acid in the body. So if another brand is offering you MCT oil that promotes C12, then they are selling you a diluted product. It appears to be cheaper, but you're not getting the concentrated MCTs that you're looking for.
MCTs have been used to treatseizures, malnutrition, gut dysbiosis, and malabsorption syndromes. This is because some MCTs bypass the liver and can be very quickly and easily converted into energy for the body and brain.
Since the 1980s, MCTs have become increasingly popular with people who have adopted Paleo, LCHF and Ketogenic lifestyles. Today we see the greatest uptake from people interested in these lifestyles to achieve their weight-loss goals. That said, MCT oil is also enjoying popularity with athletes, insulin resistant individuals and biohackers. People who switch to ketogenic style diets typically report improved energy levels, reduced weight, increased satiety and improved cognition. There are indications that Capric, Capyrlic and Lauric MCTs are good for gut health and may offer more specific uses, for example, in combating candida overgrowth.
Now that the myth that saturated fat and cholesterol are harmful to health has been thoroughly debunked (1), there has been an upsurge in health and nutrition experts advocating for the consumption of more saturated fats like butter, coconut oil, and MCT oil. Many of us are even putting these fats in our coffee!
Whether you’re aBulletproof Coffee veteran or you’re considering giving it a shot, you may be wondering what the difference is between these sources of MCTs and how you can benefit by incorporating them into your life. In this article, we will discuss the science behind MCTs and offer practical tips on how to utilise these oils for greater energy, vitality, and performance.
First, let’s take a look at the nerdy stuff:
MCTs are made up of fatty acids. Fatty acids are classified according to the number of carbons in their chemical structure.
Short chain fatty acids have fewer than 6 carbons. These are the primary fats in butter and ghee.
Medium chain fatty acidshave 6-12 carbons. This is the primary fat found in coconut and palm oil.
Long chain fatty acids have 13-21 carbons. These are the most prevalent in Western diets. Common examples include vegetable oil, nut oil, and fish oil.
The medium chain fatty acids are then further subdivided by the number of carbons. The shorter the chain, the more quickly it can be absorbed.
Caproic acid (C6) has 6 carbons - Easily absorbed, but quickly causes digestive distress. For this reason, it is best avoided. Unfortunately, it is found in many MCT oil products, so always check before buying. It's not worth losing a day clinging to your toilet!
Caprylic acid (C8) has 8 carbons - The only MCT in Bulletproof Brain Octane Oil. Caprylic acid is easily utilised for energy and enhances cognitive function. C8 is also beneficial in promoting a healthy microbiome. However, it is usually absorbed and used for energy before it can make it’s way to the colon. Therefore, if you have candida, dysbiosis, or otherwise poor gut health, it is best to use an encapsulated slow release C8 likeBulletproof Brain Octane Softgels. Note that the dose of a capsule is typically just under 1ml while a teaspoon serves 5ml. So a handful of capsules is needed to achieve an effective dose. Aside from the possible therapeutic benefit, softgels are more convenient for travellers.
Capric acid (C10) has 10 carbons - C10 is more closely associated with metabolic functions. It is not quite as easily utilised as C6 or C8 but it still bypasses the liver during digestion. Capric acid is good for those who are trying to lose weight and are not in need of the fastest ketone infusion. Bulletproof XCT oil is a combination of C10 and C8 MCTs.
Lauric acid (C12) has 12 carbons - Although technically considered an MCT, lauric acid must be processed by the liver therefore not delivering the same therapeutic effects of the shorter MCTs. Lauric acid acts more like a Long Chain Triglyceride. C12, the primary MCT incoconut oil, has however been shown to have beneficial antimicrobial effects. (2), (3), (4)
Don’t worry, this won’t be on the test :-)
But, this information is relevant to our conversation. As you can see, each different MCT has different biological effects. C6, for instance, is known to cause gastrointestinal distress, which is not going to help you achieve optimal performance! Unfortunately, many MCT oils on the market contain C6. So we want to avoid those!
Therefore it is important to know which MCTs are in the oil you are using and which MCTs will help you achieve your own particular goals.
1. Bulletproof Brain Octane Oil is pure caprylic acid (C8) and easily utilised by the brain as ketones. This is your best bet for optimising cognitive function.
User reviews of Brain Octane Oil support the notion that the ketones are rapidly absorbed. People report almost immediate feelings of energy and the clearing of brain fog. Brain Octane Oil is generally better tolerated than a combination of C8-C10 oils.
2. The combination of fatty acids in Bulletproof MCT OIL - caprylic acid (C8) and capric acid (C10) - makes it ideal for aiding in metabolic function and digestive health. It's a great pantry staple and suitable replacement for other fats.
These oils are liquid at room temperature and therefore easily incorporated into salad dressings and sauces. In addition to Bulletproof coffee, you can also blend your MCTs into tea, smoothies, and soups. Another option is just drizzling a bit of oil onto meat, vegetables, or rice. It is especially delicious with sushi! Although flavourless, MCT oil brings out the flavour of whatever it is added to.
3. MCT Oil Powder can be used as a zero-sugar, dairy-free coffee creamer, smoothie or pre-workout addition to provide the brain with energy and fat-burning ketones. An MCT powder is generally easier on the stomach compared to an MCT oil. From keto coffee to keto brownies, this is a versatile keto-lifestyle addition everyone needs in their pantry.
Start low (1/2 teaspoon) and build up to a maximum of 3 tablespoons (unless advised otherwise by your doctor). Your tolerance and energy requirements will determine your dose. Over several weeks, people tend to increase their dose as their body adapts to the higher fat intake and using ketones as a fuel source. Avoid taking too much or taking it on an empty stomach. Gastric distress will result and you may end up needing to spend the rest of your day within reach of a bathroom.
Coconut oil is arguably a pantry staple on the ketogenic diet. It can be used for sautéing and cooking meat and vegetables. It will, however, have a noticeable coconut flavour unless you opt for a highly refined (deodorised) oil. Watch out for damaging refining techniques that use heat or harsh solvents. Coconut oil has a relatively low smoke point, so it is not ideal for high-temperature cooking. Animal fats are typically best suited for this task, as is a ghee and coconut oil blend. The combination of the two naturally raises the overall smoke point.
Brain Octane, MCT, coconut oil as well as grass-fed ghee are all healthy additions to a biohacker's diet. Which of these oils you decide to use depends primarily on your goals and preferences.
MCT oils were the first Keto supplements. They were followed by Ketone salts and then Ketone Esters. The chart below will give you an idea of how each of these three work.
