Our Review of the 3 Best MCT Oils

Like any other popular dietary brands, it is hard to cut through the marketing noise and know the top sources for MCT oil.

The health quality of brands can vary drastically, and there are different levels of purity and performance that need to be considered before buying.

The number of brands available, all of which proclaim to be the top 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 premium 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 brands, we have detailed the top three below.

1. 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.

In reality, there is no real need to add flavoring to this product since it mixes well with everything but it is a nice touch. 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.

Just before we get into the section of the greatest MCT powder supplements that we have reviewed on this website. Let's quickly run through what C8 MCT oils are first and what it does to our health. 

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 fatty acid C8 is considered optimal for many reasons.

Let us learn more about fatty acids.

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.

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

Does it help you maintain a healthy weight? To be direct to the point, C8 oil is not phased and will continue to be absorbed by the GI tract so that it can go to work burning fat (saturated fat).

This alone should be enough of a selling point for anyone who is in search of the health benefits of being in a diet but is having a hard time adhering to a strict carb-free diet and food plan.

Because whether you're in a state of ketosis or not, C8 MCT oil will continue to create fat burning ketone bodies which are pretty awesome.

So, What is the Leading 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:

  • 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 ingredients themselves and by extension a higher level of cognitive function.

  • More Effective Workouts - While more study is needed small, preliminary studies suggest that C8 MCT oil can improve the effectiveness of your workouts and allow athletes to perform at a higher level.

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

What are the Top MCT Powder Supplements?

While most people are familiar with using it, a recent innovation has been the creation of premium MCT oil and powders.

These powders contain the same combination of fatty acids including C8 (Caprylic Acid), C10 (Capric Acid) and C12 (Lauric Acid) as those mentioned above, but to turn the oil into a powder, it has to go through an additional manufacturing process. 

It 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 health positives and negatives to the leading MCT powders - let’s review them.

1. Perfect Keto

Perfect Keto

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.

3. 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 weight loss product then check out this in-depth Keto Kreme review that we did.

Now, let’s review the benefits you can expect when using top-rated MCT supplements like this.


  • Assists with blood glucose
  • Works really fast
  • Easily absorbed by the body
  • Great customer feedback

What are the Benefits Of MCT Oil?

One of the hardest things about getting into a diet and food plan is understanding the science behind it. So, today we're going to talk about the benefits of MCT oil products.

You can always do what everyone else says to do, but it is usually a nice idea to understand what is going on in your body and why. Here, we will look at some of the main benefits of MCT oils or powder as a keto supplement (see our suggestions) and address some common myths, rumored side effects, and any misconceptions related to it.

Appetite Reduction

The biggest health benefit that MCT oil users usually find is appetite reduction which aids greatly in a healthy weight loss process. This is achieved due to the high energy concentration found in the effect of MCT oil. The long chain fats found in here are easily available to your body with low to almost no processing at all. Not to mention, ingesting this stuff improves your metabolism.

Improved Cognitive Ability

One of the health benefits of MCT oil that is often overlooked is the enhancement they can provide to your cognitive functions. This is mainly attributed to the concentration of fats in these that are used by the brain for cognitive abilities.

Increased Energy

As mentioned already, the long chain fats found in these popular products are very easily digested by the body. The beauty of MCTs is they pass through the empty 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 enhancement to your everyday routine, you will enjoy these nutrition and health benefits.

Are There any Possible MCT Oil Side Effects?

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 MCT oil 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 supplements, then they can be an efficient and healthy source of concentrated fuel for your body that is not tied to carbohydrates.

Many people who have experienced any side effects or symptoms initially see they can reduce them by taking it with non-GMO food or by simply taking smaller doses.

Also be careful that you’re not taking it at the same time you are consuming other organic food that may also contain MCTs - like butter, cottage cheese, and palm kernel oil - as this could exacerbate negative side effects of MCT.

Some also say that MCT oils improve your gut health and digestive system, the ability to fight off diseases, and even put you in an overall better fitness level.

Some will say that the jury is out on the side effects of MCT, but that seems to overstate the issue.

The fact is millions of people around the world take it on a regular basis to enjoy all of the MCT oil benefit listed above, and there is virtually no evidence of it doing any more harm than the occasional empty stomach or case of diarrhea.

Not to minimize the discomfort those conditions might cause, using them to support the argument that it may be harmful to one’s nutrition and health is the specious reasoning.

The bottom line regarding side effects is that they appear to be somewhat rare and typically mild. If you're not yet convinced how amazing these products are because of its nutrition and health benefits, 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.

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

girl thinking

The most significant debate among users of these products is which form works better? A lot comes down to personal preference.

At their core, both medium-chain triglycerides 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 essential fatty acid or fatty acids C8 (Caprylic acid) and C10 (Capric acid) 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, fatty acid often has 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 MCTs to food. 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 one of the people that have checked out tons of MCT oil weight loss process reviews, then you probably know by now that this stuff works. It's built to provide you high performance and improve your body's ability to burn fats. You can't beat that. So, if you are wondering where to get the most effective MCTs 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 brand.

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

Second, you should be looking at the sources of the fats. These are made entirely from coconut oil. Not only have the fats from coconut oil (not olive oil) have been used for years to achieve ketosis, but coconut oil-based products are also a more ethical choice.

To help you choose a top quality 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 this ingredient 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 Fatty Acids: 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 MCTs without all the hassle, security risks, and shipping issues that have become somewhat common today. So, here’s how to get quality MCT products without extra high costs or raw ingredients that you can use to improve your diet and food intake.

Where's the Perfect 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 these, we're going with the one that has a better value for your money. This is why MCT oil by Onnit is regarded as the most effective 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 perfect Keto MCT oil, your bet is to get it straight from the manufacturer which we have provided below.

From MCT oil, moving on to premium MCT powder. As we've previously mentioned, products without added derivatives may be a leading 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. We have included the link to their official website just below where the top deals can be found.
