If you are into keto, then you’ve probably heard the buzz about MCT ​oil powder products for some time now. The question is, which of these supplements should you be using for the best results?

Medium-chain triglyceride (MCT) based products have been scientifically proven to provide long lasting energy to your body in an easy to digest form. Fat based energy supplements like these are essential to any good ketosis diet, which is why MCT products have received so much positive attention.

Here, we’ll examine the difference between MCT oils and powders in depth. There is a lot more to consider than you may have realized and not every MCT based product is created equal!

Don't worry though; we’ve tried out the top rated brands to find out which oils and powders give you the best bang for your buck.

Many people have already done the hard work and tested the full range of supplements. Thanks to their research, we have access to reliable, evidence-based conclusions about which products are the most effective. We’ll review the most popular ​MCT oil powder products available and combine them with industry expert opinions to reveal which ones are most effective.

First, let's take a closer look at the leading MCT oil products currently available.

Our Review of the 3 Best MCT Oil Products

Like any other popular dietary supplement, it is hard to cut through the marketing noise and find the best source for MCT oil. The quality of brands can vary drastically, and there are differing levels of purity and performance that need to be considered before buying. 

The number of brands available, all of which proclaim to be the best and most effective, can seem overwhelming. A lot of this is hype and false claims that can trap the unwary buyer. There are only a select few brands of MCT oil that stand out above the rest. So that you don’t go out and waste your time and money on inferior medium-chain triglyceride products, we detail the top three brands below.


Onnit MCT Oil

The Onnit range of MCT oils is massively popular right now, and it is not hard to see why. 

MCT oil in its natural form is completely flavorless, but Onnit has released a range of added flavor, which some people find great for mixing with other foods.

The reality is there is no real need to add flavoring to this product since it mixes well with everything. Because MCT oil is naturally without flavor, one of its main attractions is it can be added to foods and hide behind the existing flavors in an unobtrusive way.

Although some people may enjoy the flavored options sold by Onnit, the original version works just as well. The high performance of this product is notable, but it does come with a slightly higher price tag than other brands. If you want to learn more about this product, you can read our Onnit MCT oil review.

Bulletproof Brain Octane

Bulletproof brain octane oil

If you know anything about the Bulletproof brand’s story, then you know the company rose to fame with the use of fats, like butter or coconut, in coffee as an energy booster.

Their new ‘Octane Oil,’ which is MCT oil, was the next logical step. The best and most easily digested oils found in coconuts are concentrated in Octane Oil.

This means you will get a much bigger energy boost using this product than using butter or coconut oil alone. As a trustworthy company with a history with these kinds of products, you can feel safe relying on the experience of the Bulletproof brand.

Simply put - it’s hard to go wrong with this one!

The high-grade quality and effectiveness of Octane Oil makes it my choice for the #1 MCT oil on the market today and the best bang for your buck. If you want to read our personal review, click here


  • A great pair with BHB supplements
  • Enhances cognitive ability

  • Safe for consumption


  • A tad bit expensive
  • May cause stomach ache if over-consumed

Left Coast MCT Oil

Left Coast MCT Oil

Another great option for pure MCT oil is brought to you by the company Left Coast.

This particular product is of a high-grade quality, derived solely from coconuts. Some other brands blend their coconut sourced oil with palm oil derivatives.

While the MCT from each source is technically the same, palm oil is a highly unethical product and should be avoided.

Most people who use Left Coast MCT oil find it to be one of the purest options out there in its price range and that is saying a lot about this product.

While users often find results vary with this brand - If you are budget conscious, then try Left Coast as it’s one of the best in its price category.

Now, let’s review the best powdered MCTs in the market today.


  • 100% Made in the USA
  • Premium quality MCT
  • Guaranteed purity
  • Easily absorbed and digested


  • Expensive
  • Missing some key ingredients found in the above products
  • May cause stomacheache if over-consumed

Just before we get into the section of the best MCT powder supplements that we have reviewed on this website. Let's quickly run through what C8 MCT oil is first. 

What is C8 MCT Oil?

Like all MCT oils, C8 is a refined form of coconut or palm oil. C8 oil is used to aid in achieving ketosis and in some cases mimicking its effects for short periods of time. By doing so, it helps the body burn fat, lose weight, reduce blood glucose levels and increase energy levels. C8 MCT oil gets its name from the fact that it is Caprylic acid (C) and has 8 carbon atoms in its molecular string (8). Other forms of Medium Chain Triglyceride oil may have 10 carbon atoms or more in their molecular string, but C8 is considered optimal for many reasons.

What's So Special About C8 MCT Oil?

Copious research has demonstrated that ingestion of C8 MCT oil is an efficient way to increase the body's production of fat burning ketones significantly. Indeed, ingesting even modest amounts of C8 oil has been proven to increase the number of ketone bodies in the blood by up to 5 times. And since it is ketone bodies that burn fat to produce energy this is precisely what anyone seeking the benefits of ketosis should be looking for in a Ketone supplement.

A More Reliable Fat Burner

Whereas some ketone supplements become neutralized if the person taking them consumes carbohydrates C8 oil is not phased and will continue to be absorbed by the GI tract so that it can go to work burning fat. This alone should be enough of a selling point for anyone who is in search of the benefits of ketosis but is having a hard time adhering to a strict carb-free diet. Because whether you're in a state of ketosis or not C8 MCT oil will continue to create fat burning ketone bodies. 

So, What is the Best C8 MCT Oil?

From our experience testing all the different brands currently available, we would wholeheartedly recommend Perfect Keto C8 MCT Oil. Perfect Keto is the very definition of purity containing 100% Triglycerides. The results of this are quantitative and include:

  • check
    Enhanced Cognitive Function - Perfect Keto has potent antimicrobial properties that promote the cleansing of your gastrointestinal tract. This allows for more efficient absorption of the MCTs themselves and by extension a higher level of cognitive function.

Now, let's get into the our favorite powders...

What are the Best MCT Powder Supplements?

While most people are familiar with using MCT oil, a recent innovation has been the creation of MCT oil powders. These powders contain the same combination of C8 (Caprylic Acid), C10 (Capric Acid) and C12 (Lauric Acid) as the oils mentioned above, but to turn the oil into a powder, it has to go through an additional manufacturing process.

The oil is combined with a powdered ingredient such as soy lecithin, corn fiber or maltodextrin before it’s dried. Many people have been drawn to powders due to the ease of transporting them, especially when traveling by plane. Also, they prove quite useful for those using other powdered supplements as it is easier to blend them accurately.

There are both positives and negatives to the best MCT powders - let’s review them.


Perfect Keto

MCT Powder

One of the big problems people have transitioning from oils to powders is the potential glucose spike caused by the additives needed to turn the oil into powder.

Perfect Keto has been able to solve this problem with their method of creating MCT powder without these additives.

Most users find the Perfect Keto powder ideal for use with coffee or as an addition to protein shakes as it seamlessly blends with liquids and other powders. Because it is made from 100% coconut based MCT, you can rest assured the product is pure and environmentally responsible.

In our opinion Perfect Keto stands apart from the competition and provides unrivaled quality, making it the best choice among MCT powders in the market right now. Also, it doesn't hurt that the company knows how to make ​their MCT products taste ridiculously delicious!

Keto Kreme

Coming from a keto-powerhouse of a company called Pruvit, this is yet another standout product from their lineup of weight loss products. Keto Kreme is an MCT powder designed and packaged specifically as a substitute for butter or oils most commonly used with Bulletproof coffee.

The main idea behind bulletproof coffee is blending an oil or fat with regular coffee to give an energy boost, but this can be a complicated process.

Keto Kreme comes in sachets similar to regular coffee creamer, and it behaves similarly when added to coffee.

This ease of use, as well as the complete absence of dairy or animal products, has made this a trendy choice for those looking to achieve ketosis. Although high quality, the sachets can be a bit expensive. If you want to learn more about this product then check out this in-depth Keto Kreme review that we did.

What are the Benefits Of Using MCT Products?

One of the hardest things about getting into a keto diet is understanding the science behind the supplements you use. You can always do what everyone else says to do, but it is usually a good idea to understand what is going on in your body and why. Here, we will look at some of the main benefits of using MCT oil or powder as a keto supplement (see our suggestions) and address some common myths and misconceptions.

Appetite Reduction


One of the biggest benefits users of these products find is appetite reduction, which aids greatly in weight loss. This is achieved due to the high energy concentration found in MCT oil products. The long chain fats found in these products are easily available to your body with almost no processing.

Improved Cognitive Functions

A benefit of MCT oils that is often overlooked is the boost they can give to your cognitive functions. This is mainly attributed to the concentration of fats in these products that are used by the brain for cognitive functions.

Increased Energy

As mentioned already, the long chain fats found in these popular supplements are very easily digested by the body. The beauty of MCT’s is they pass through the stomach and into the intestine almost immediately, where they are absorbed and used by your body. No matter if you achieve ketosis, or want a little boost to your everyday routine, you will benefit from using these supplements.

When compared to other dietary aids, MCT oils and powders have a meager cost per dosage and have a truly massive positive impact on your body. Of course, some misconceptions are surrounding these supplements, which need to be addressed.

First of all, there is the natural resistance to using concentrated fat as part of a healthy diet. So, as long as you are using the right kind of fats, such as those found in MCT oil, then they can be an efficient and healthy source of concentrated fuel for your body that is not tied to carbohydrates.

Another common problem people encounter with these supplements is they can cause some digestive stress, including more frequent bowel movements. This is a legitimate problem, but as long as you start with small doses and follow the manufacturer's recommendations, your body should adjust over time.

If you're not yet convinced, just check out this video below.

But how do you know if you should use an oil or powder? Let’s see what real users say about the debate between the two.

MCT Oil vs Powder, What's Better Between the Two?

The biggest debate among users of these supplements is which form works better? A lot comes down to personal preference. At their core, both the oil and powder form of medium-chain triglyceride supplements deliver the same long-chain fats to your body. However, there are some slight differences worth noting.

First, we need to look at the density of the crucial C8 and C10 fats in different types of products. Due to the nature of powdered products, which are created with the help of an agent such as corn fiber or soy lecithin, they often have the long-chain fats at a lower concentration than oils. This can make calculating dosages with powders difficult.

However, if you choose powders that are free from additives and pure, it addresses this concern. Some people prefer using powders because they seamlessly blend into a full variety of liquids, or can be utilized as a substitute for flour in baking.

This can come across as a massive advantage and expands the ways you can add MCT to foods. Another advantage of powders is they are easier to travel with. If you are using only a carry-on, there are some very severe restrictions on liquids, but no issues with powders.

If you are wondering where to get the best MCT supplement on the internet, here’s how to buy your preferred brand without getting ripped off.

What Goes into Making a Quality MCT Supplement?

There are two main factors to consider when looking for a high-quality MCT supplement.

First, you should look for a product that has been well refined and contains all or mostly C8 and C10 fats. These two types of long-chain fats have been proven to have positive effects, while others are unproven or known to be less useful.

Second, you should be looking at the source of the fats. The products are made entirely from coconuts. Not only have the fats from coconuts been used for years to achieve ketosis, but coconut based products are also a more ethical choice.

To help you choose a quality top product, there are also some things that you need to avoid. Here are some ingredients you don’t want to see on the label:

  • Palm Oil: This is grown at the expense of old growth rainforests and the animals that live there. Any product using palm oil is a company that doesn’t care and is cutting corners.
  • Additives: Anything other than pure oil or powder should be avoided, as you will not achieve the optimal concentration of long-chain fats. Flavorings fall into a bit of a gray area.
  • Other Fats: As mentioned above, C8 and C10 are the fats you are after. Any blend that includes other fats is diluting the effect of the healthy fats and not helping you reach your goals.

Now, that we've reviewed the different things that you should be looking for when it comes to the right MCT oil or powder. Let's quickly review where you can buy MCT products without all the hassle, security risks, and shipping issues that has become somewhat common today. So, here’s how to find quality medium-chain triglyceride products without extra high costs or raw ingredients that you can use to improve your diet.

Where's the Best Place to Buy it?

Let's start off with the liquid form. So, what is the best MCT oil for keto in our opinion?

Well... after a testing a bunch of the most highly recommended products that we could find, we ended up with two products that stood out. Bulletproof and Onnit. And after we compared both products side by side to see which one has the upper hand, it was about dead-even with Onnit having the slight edge in effectiveness. That wasn't enough to say that Onnit was way better than Bulletproof though, so then, we looked at their prices to settle the argument.

Since no one wants to break the bank when it comes to buying supplements, we're going with the product that has a better value for your money. Which is why the pure MCT oil by Onnit is regarded as the best in our opinion. It offers unparalleled value for the price and is the highest-grade quality that money can buy. So, if you are wondering where to buy this MCT oil product, your bet is to get it straight from the manufacturer which we have provided below.

Moving on to MCT powders. As we've previously mentioned, products without added derivatives may be the very best option for convenience and ease of use. Perfect Keto MCT Powder is the top choice among consumers and it's recommended in the world of dieters. The way to get the discounted price is to buy it straight from the manufacturer as well.
