Best MCT oil

MCT oil benefits the body in many ways. MCT oil quickly converts to energy, and some studies show it can help you lose weight. It also acts as fuel for the brain and can help improve cognition.

MCT oil can be derived from coconut oil or palm kernel oil, with each source having a different ratio of MCT types. C8, like that found in LevelUp Clean MCT Oil, is often considered the best because it can instantly convert to energy. This particular formula also earns high marks for its purity and sustainable sourcing practices. 

What to know before you buy MCT oil

What is MCT oil?

MCT oil is a type of supplement made from medium-chain triglycerides, a form of fatty acids. There are three types of fatty acids, short-chain, medium-chain and long-chain, classified by the number of carbon atoms of which they are composed. Short-chain triglycerides have fewer than six, medium-chain have between six and 12 and long-chain have between 13-21.

The average person’s diet contains primarily long-chain triglycerides, which take a long time for the body to digest. Because of this, many of them wind up stored as fat. Conversely, medium-chain triglycerides can be absorbed into the bloodstream quickly, where they rapidly turn into a source of energy.

Types of MCT

There are four types of MCTs: caproic acid, caprylic acid, capric acid and lauric acid. Of these, caprylic and capric are the most commonly used in MCT oils. These have eight and 10 carbon atoms, respectively, which is why they are referred to as C8 and C10 MCT. 

When searching for MCT oils, you’ll find that many are made of a combination of one or both of these and other types. However, if you see clean C8 MCT oil on the label, this means it contains only that form of MCT and no others.

Ideally, you want to choose a clean C8 MCT oil, as this is most quickly broken down by the body and turned into fuel due to its low number of carbon atoms. C10 takes slightly longer, and lauric acid, sometimes referred to as C12, takes the longest.

What is MCT oil good for?

Most people who take MCT oil do so as part of a keto meal plan or modified Atkins diet to help them lose weight and increase their energy levels. This is because MCT oil can convert into ketones, which the body starts using for fuel when following a severely carbohydrate-restricted diet and your body goes into ketosis.

Ketones can cross the blood-brain barrier, making them excellent brain food. Because of this, some experts recommend that people with Alzheimer’s disease, or those predisposed to developing it, should consider taking MCT oil and following a ketogenic diet.

Source of MCT oil

The majority of MCT supplements are derived from coconut. However, this may not be the best choice. Coconut-derived MCT oil is high in C12. Unlike C8 and C10, C12 is not immediately converted into energy. Instead, it is processed through the liver first. 

Palm oil is often considered a better source for MCTs because it has much higher percentages of C8 and C10. Another good option is to choose an MCT oil made from a combination of coconut and palm-kernel-derived MCTs.


Any time you introduce a new food or supplement to your diet, you should consider allergies. Many MCT oils are derived from coconut, and though they are not actual nuts, some people with tree nut allergies are also sensitive to coconuts. If you are unsure, you may want to consider an MCT derived from palm kernel oil instead. 

Features to look for in quality MCT oil


It is always best to avoid imbibing chemicals when possible, so you should look for a certified organic MCT made from coconut or palm trees grown without pesticides, herbicides and fungicides. The price difference between organic and non-organic MCT oils is negligible, and the organic variety tends to be non-GMO too.


MCT oil itself has almost no flavor or smell, though some may find it a hint bitter. To make it more enjoyable when adding to foods or beverages, you can buy a flavored option. Common flavors include vanilla, chocolate and caramel.


MCT oil is very thin, which means it comes out of the bottle quickly. This leads many people to pour out more than they intended accidentally. Buying an MCT oil that comes in an easy-to-dispense bottle with a squirt top can help prevent this.

How much can you expect to spend on MCT oil?

MCT oils generally cost between $10-$25 for a 16-ounce bottle, depending on the purity, source and certifications.


Is liquid MCT oil better than MCT oil powder?

A. In regards to health benefits, MCT oil liquids and powders are comparable. However, some may find their body tolerates a liquid better, or vice versa. Also, liquids are easy to mix in with both solid foods and beverages, whereas powders are best reserved solely for mixing into beverages. That said, powders are more convenient to take on the go.

How much MCT oil should I take per day?

A. You should take 15-30 milliliters with each meal, up to three times a day. Depending on how well your body tolerates it, your maximum daily intake can be somewhere between 50-100 ml.
