Frequently Asked Questions

I know you were looking for what are the best options, but here is some more detail as to why we would want to consider using medium chain triglyceride oils on a low carb or ketogenic diet.

What is MCT Oil?

MCT Oil stands for Medium Chain Triglycerides oil. MCT’s are a type of healthy saturated fat not found in most foods. They are also sometimes called Medium Chain Fatty Acids (MCFA).

MCT’s are often used by people who are on keto diets for weight loss or wanting to be in nutritional ketosis, but it can have benefits for those eating a normal diet as well. (ref)

How Does MCT Oil Help Ketosis?

Consuming MCT oil will act as an exogenous ketone supplement and is different to when you make endogenous ketones by burning body fat.

Medium chain triglycerides are designed to bypass the bloodstream and go straight to the liver where they are directly metabolized into ketones. This increase in ketone levels will help you get into nutritonal ketosis.

The Types of Medium Chain Fatty Acids

Different types of MCFA’s are metabolized differently. The following is a list of the different types of MCFA’s your MCT oil might contain. (ref)

Most MCT oils are comprised of C8 and C10, but some also include C12. Lauric acid has been shown to have stronger antimicrobial properties than the other acids, but not all MCT oils include lauric acid.

Amount of Medium Chain Triglycerides in Food

Here is a breakdown of the MCT composition found in each common type of food. (ref)

Does MCT Oil Help Weight Loss?

Consuming 18-24 grams/day of MCT oil during a weight-loss plan of up to 16 weeks has been shown to help with fat loss when compared to consuming olive oil. (ref)

It is thought that MCTs aid in modest weight loss by increasing energy expenditure leading to better body composition. (ref)

When to Use MCT Oil to Help Improve Ketone Levels?

Since ketones are a primary source of fuel for both your brain and body, there are numerous use cases for wanting more beta-hydroxybutyrate (BHB) in your blood.

Higher ketones might help people with the following health conditions.

What Are the Benefits of MCT Oil Supplements?

MCT oil supplements can have other benefits aside from being used to help to treat or manage health conditions.

Healthy individuals may see the following benefits when using MCT oils:

How to Take MCT Oils?

Here are some popular ways people like to use MCT Oil:

If you are travelling you may find using an MCT oil powder more convenient to take on the road.

MCT oil can also be taken by itself. Since it is tasteless and odorless, it can go well in almost any food.

How Much MCT Oil Should You Consume?

According to University of Virginia research the maximum tolerated daily dosage of MCT oil can be up to 4-7 tablespoons (60-100ml). (ref)

Most people first starting to take MCT oil will want to take 1 tablespoon (15ml) per day for 3-4 days to assess for any gastrointestinal comfort then take between 1-4 tablespoons per day thereafter. This is different for MCT Oil powders.

Possible Side-Effects

One of the most common side-effects is gastrointestinal discomfort, which can include the following symptoms.

Even if you are healthy, you may experience some side-effects when taking MCT oil.

To offset these potential side effects, start with a small dose of MCT oil and work up slowly to a larger dose. Also try taking the oil with food.

Is It Safe to Take MCT Oil?

MCTs are considered generally safe for most healthy people.

An exception is those with high cholesterol, specifically high triglyceride levels, since MCT oil might increase triglyceride levels.

When Not to Use MCT Oil?

MCT Oil vs Coconut Oil

MCT oil is considered superior to coconut oil for ketogenic diet supplementation due to its higher concentration of caprylic acid and capric acid. While coconut oil by itself only contains about 15% MCFAs, MCT oil is comprised of up to 100% MCFAs.

Here is a side-by-side comparison of the two.

Coconut OilMCT Oil
Contains 2 grams of MCTsContains up to 15 grams MCTs
Has antimicrobial propertiesMay or may not have antimicrobial properties
Has other health benefits asides from MCTsHas no other health benefits
Costs 45 to 60 cents per gram of MCTsCosts 2 to 3 cents per gram of MCTs

On the flipside, coconut oil has other properties that can have a wider range of health benefits. Which product you choose depends on what results you are looking for.
