A lot of people like Brain Octane Oil because they feel that it gives them mental clarity and clears brain fog.
Brain Octane Oil may also help support a strong immune system and healthy digestion because it promotes good gut bacteria.

- Affordable one-pound bag
- Organic MCT C8 MCT powder
- Comes from organic coconut

We like this pick for the best MCT oil powder for a few reasons.
First, Micro Ingredients is one of our favorite brands in general.
We think they have generally high-quality products. We also like the idea of using this powder version of if you deal with stomach upset from other types of oils because powder can reduce those symptoms.

Then, to top it off and make it an even better product, it contains the prebiotic acacia to help promote gut health and reduce symptoms like bloating.
This MCT oil has many possible benefits for weight loss, including better nutrient absorption thanks to acacia and the fact that it’s a source of beneficial bacteria and amino acids.

The Brain Octane Oil is rapidly absorbed, providing instant energy and mental clarity.
This particular MCT oil is also good for digestion.
We should note, however, that if you’re just starting with MCT oil, don’t assume that you should use the entire packet.
In fact, you more than likely shouldn’t.
You should start gradually with no more than a teaspoon of Brain Octane Oil when you start out using it.
What is MCT Oil?
MCT oil is a supplement made from a specific type of fat known as medium-chain triglycerides. MCT molecules are smaller than those found in most fats, so they can be digested and absorbed into your bloodstream faster.
The oil comes from either coconut or palm kernel oil, and when we were selecting the best MCT oil, our preference was for coconut-derived oils.
There are a few different types of specific medium-chain fatty acids, which are:
- C6: This is also known as caproic or hexanoic acid
- C8: This is sometimes the preferable oil and the only one in Brain Octane Oil. It’s also known as caprylic or octanoic acid.
- C10: This is called capric or decanoic acid.
- C12: This MCT can also be known as lauric or dodecanoic acid.
The MCTs you most commonly see in supplemental forms are C8 and C10.
Lauric acid is very rarely, if ever, in these products because there aren’t any major health benefits associated with this type that we know of right now.
MCTs have a short chain length, and that allows them to be broken down and absorbed quickly by your body.
They go right to your liver, and then your body can use them as an energy source or turn them into ketones.
Your body produces ketones when your liver breaks down significant amounts of fat.
Ketones can cross the blood-brain barrier, fueling the brain as an alternative source. Otherwise, the brain uses glucose for fuel.
Your body only produces ketones when it doesn’t have enough carbohydrates. This is the point of the keto diet—to put you into the metabolic state of ketosis.
You don’t consume many carbs, and then your body is forced to create ketones and use them as energy instead of glucose, which would do if you were consuming carbs.
The calories in MCTs are turned into energy so quickly and then used by your body so that they’re not very likely to be stored as fat, which is one reason some believe MCT oil can help with weight loss.
What Are the Benefits of MCT Oil?
MCT is one of the most popular supplements right now, and there’s some research to back up the claims of benefits.
Probably one of the most common reasons people are looking for the best MCT oil is to help with weight loss.
There are multiple ways it can aid in weight loss.
First, MCT might increase two hormones that promote feelings of fullness—leptin and peptide YY.
There was a study that found two tablespoons of MCT during breakfast led to people eating less at lunch compared to people who used coconut oil. Other studies, while older, have also indicated MCT oil might reduce waist circumference and body weight, and it may play a role in preventing obesity.
If you follow a ketogenic, low-carb, high-fat diet, you’re much more likely to see these benefits if you also add MCT to your routine. MCT oil may help you get into ketosis faster and stay there.
MCT oil has also been shown to help promote healthy gut bacteria, which can help with weight loss.
Along with weight loss, one of the other most common reasons people look for the best MCT oil is to boost their energy.
Because of their short-chain structure, MCTs can travel rapidly from your gut to your liver. They don’t need bile to be broken down.
Then, when MCTs reach your liver, they can be immediately used for energy.
If you’re following a keto diet, your liver also converts MCTs into ketones. Ketones can cross the blood-brain barrier, giving your brain a source of clean energy.
Mood and Brain Health
MCTs are thought to really nourish your brain in a unique way.
For example, research found that taking this oil can improve your brain injury by as much as 9%.
Especially when you take MCTs with a high-fat, low-carb diet, they can delay brain aging and help repair brain cells.
MCT oil also helps promote good bacteria in your gut, and that then helps your brain produce two neurotransmitters responsible for giving you a mood boost—serotonin and dopamine.
These neurotransmitters, interestingly, are created primarily in your gut.
Currently, researchers are even considering using MCT oil for dementia and Alzheimer’s treatment.
Some experts view these brain diseases as similar to diabetes in that brain cells lose their ability to absorb glucose.
When that happens, they don’t have an energy source, so they die. PET scans have shown that parts of the brain affected by Alzheimer’s can take up ketones as a fuel source.
We’ve also seen that ketogenic diets have benefits for people with Alzheimer’s and dementia.
Antimicrobial and Antifungal Effects
MCTs have been shown to reduce the growth of various funguses and bacteria.
For example, in one study, coconut oil, which contains MCTs, reduced the growth of the bacteria C. diff.
MCTs have been shown to reduce the growth of a wide variety of different infectious fungi in hospitals by as much as 50%.
There are some indicators MCT could reduce the risk factors linked to heart disease, including inflammation and blood pressure.
MCT may also reduce cholesterol levels and, in particular so-called bad cholesterol or LDL.
MCT may reduce C-reactive protein, which is an inflammatory marker thought to increase heart disease risk.
When you take this oil, it might help with fat burning and storage, which can, in turn, help you keep your diabetes better controlled.
For example, there was a study of 40 older people with diabetes.
In that study, the people who took MCT oil daily had reductions in insulin resistance, waist circumference, and body weight.
In a separate study, 10 people with diabetes needed 30% less sugar to maintain normal blood sugar levels when they consumed MCTs.
Do MCTs Have Side Effects?
You should talk to your doctor before taking MCTs, particularly if you have any pre-existing health conditions.
Overall, based on what we currently know, no major or common side effects are associated with their use, but that doesn’t mean side effects can’t occur.
For most people, if they experience any side effects of MCTs, they’re related to their GI system.
For example, when people first start using MCTs, they may have nausea or diarrhea.
That usually goes away as your body gets used to this type of fat.
You can also avoid the risk of GI side effects by starting slow with MCTs. For example, take half a teaspoon at first and gradually work your way up.
It’s also possible that large amounts of MCTs could lead to a buildup of fat in your liver.
However, none of the best MCT oils recommended above recommend doses that are anywhere close to what might trigger that.
The upper safe intake level is 4 to 7 tablespoons daily.
Oil vs. Powder
When it comes to choosing the best MCT oil, we featured both actual oils and powders.
You may be wondering what the differences are.
Both should provide you with the same general health benefits as long as you choose a reputable brand and product.
However, a powder may have fewer side effects than oil.
When you take an MCT powder, you may be more likely to have symptoms of digestive distress like diarrhea and nausea.
A lot of people find MCT powders are more easily digested.
Oils can be a bit messy, so some people feel powders are easier to use and also to travel with.
You may also prefer the texture of one over the other.
For example, MCT oil has, as you might think, an oily consistency. You might prefer a powder that will blend and mix more easily into drinks and other items.
Of course, you can’t use a powder as a salad dressing or as a topper for your food in the same way you can oil.
Most of the research that’s currently available on MCT supplements is focused on the benefits of oils, so we generally know less about powder, but there’s no reason to think the powder is any less effective in terms of health advantages.
How Are MCT Oils Different from Coconut Oil?
You may be wondering how the best MCT oil compares to coconut oil.
MCT oil has 100% MCTs, which are medium-chain triglycerides. It’s a concentrated source of MCTs.
Coconut oil contains MCTs, but it’s not entirely an MCT. In fact, coconut oil also has long-chain triglycerides.
Lauric acid is one of the primary components of coconut oil, and it’s slowly absorbed and digested, so it’s not as preferable as far as overall health benefits as MCTs.
MCT has advantages over coconut oil, particularly for people who follow a keto diet.
MCT is better for helping your body produce ketones and stay in ketosis.
Studies have also shown MCT oil is better for boosting your metabolism and helping you feel full for longer; therefore, it may be a better weight loss aid than coconut oil.
What Is C8 MCT Oil?
In our ranking of the best oils, a couple of the products we selected are marketed as only having C8, and in particular, this is true of Brain Octane Oil.
C8 oil is 100% caprylic acid. Caprylic acid is the most metabolically active medium-chain fatty acid, so some people believe it’s preferable to other types.
C8 has been shown to help boost ketone production and increase energy, and it may also have cancer-fighting properties.
C6 is caproic acid, which can also boost blood ketone production.
C10 is capric acid, which is similar to C10 in that it boosts ketones and can aid in weight loss, but it can take longer for the body to absorb and process.
C12 is lauric acid, and it’s not the best MCT oil for ketone production or weight loss, so most supplements don’t have it.
