MCT oil is a dietary supplement that features triglycerides of medium-chain fatty acids, a type of fat that is more easily converted into energy within our bodies. In theory, MCTs should serve as a quick and efficient source of energy and thus may have various benefits such as providing an energy boost for exercise. Moreover, some research studies suggest that MCT oil may be beneficial for weight management.
If you decide to incorporate MCTs into your routine, we have prepared a list of what we consider to be the best MCT oil products.

How to choose the best MCT oil?
When choosing the best MCT oil, it is important to consider certain factors. Below, we will give an overview of the criteria that played a role in selecting the products for our list.
|C8 and C10

- Type. Most studies used MCT oils containing C8 and C10 medium-chain fatty acids, so products containing them were preferred.
- Brand reputation. We analyzed various factors to determine the brand’s reputation such as reviews, certifications, and transparency.

Effectiveness of different MCT supplement forms
MCT oil is proposed to be helpful in weight management and gut health. However, as of now, research studies are scarce, especially comparing different MCT oil supplement forms. If you decide to use MCT, the most suitable form for you will be the one that can be easily integrated into your routine.
Most commonly, MCT supplements are sold in oil form. MCT oil itself is flavorless. It can be mixed up with food and beverages. You may also find MCT softgels and powders.
When it comes to sources, MCT oil is derived either from coconuts or palm kernel oil. When it comes to effectiveness, these two forms should not differ.
Can you use MCT oil when on a keto diet?
Yes, you can use MCT oil on a ketogenic diet as long as it does not contain any additional ingredients high in carbs.
In fact, MCT oil is preferred to coconut oil for those who practice keto since MCTs are more easily converted to ketones for energy.
The role of MCT oil in weight management
In weight loss, MCT oil is thought to boost energy expenditure and satiety, potentially reducing caloric intake. However, as of now, there are limited studies that explore MCT oil in weight management.
For instance, limited studies comparing MCT oils and other oils (olive, for instance) suggest higher weight loss with MCT supplementation.
The full impact and safety, especially in overweight individuals, require further research studies with larger participant numbers. High-fat diets, including supplementation with MCT oil, may not be suitable for those overweight, obese, or at risk of cardiovascular issues.
Best time and dosage for MCT oil supplementation
As of now, the research is scarce to give a conclusive answer.
When it comes to the best time, some studies showed no difference when you consume MCT oil. For instance, one study included elderly people divided into two groups: the ones who took MCT during breakfast and those who added it to their dinner. This study did not show any difference between the groups in measured muscle mass and function and cognition parameters.
If you're trying to determine the optimal dosage of MCT, there's no conclusive recommendation available as of now. According to the EFSA review of MCT, the research studies on MCT used a range of dosages from 1.7g to 55g per day. Moreover, no major side effects were noticed during the reviewed studies.
However, this is not to say that MCT oil is well-tolerated in all populations. In the next section, we will talk about the possible negative effects and considerations regarding MCT oil supplementation.
What to consider before taking MCT oil
While some studies suggest that MCTs may have some benefits, more research is needed to fully understand their effects, especially in the long term.
Moreover, it is crucial to know that a diet high in fat (including MCT oil) is not advised for overweight and obese people or people at increased risk for cardiovascular disease.
If you decide to incorporate MCT oil into your routine, it is best to start with lower doses. Please also consider contacting your healthcare provider to determine if MCT is the right option for your case.
