8 Best MCT Oil For Keto 2019 – A Comprehensive Buyer’s Guide

MCT Oils are one of the most sought after supplement among dieters especially keto dieters. It has been rising in popularity.

MCT Oils are packed with benefits and will help you in your keto diet greatly. The supplement is great at suppressing appetite, increase the ability of your body to burn fat and also help your body achieve ketosis.

MCT Oil stands for medium-chain triglycerides (MCTs) which is a type of saturated fat that is used by the body differently from long chain saturated fats.

How MCTs are different is that it does not need enzymes from the body to digest it and it can be absorbed by the small intestine directly and almost all of it, approximately 70% is used by your body immediately for energy production instead of storing it in the body. MCT oils are also a great source for your body as an antioxidant and antimicrobial properties which is quite a unique characteristic for a fatty acid.

Naturally, MCTs contain 60% of coconut oil, 50% palm kernel oil as well as 12% of dairy foods and there are also 4 types of MCTs. There is caproic acid (C6), Caprylic Acid (C8), Capric acid (C10) and Lauric acid (C12). Below will be the details of each type of MCT.


Caproic Acid (C6)

Caproic Acid or in short C6 is the shortest form of MCTs containing only 6 carbons. C6 is great at converting ketones faster than the other MCTs which are longer, containing more carbon. One of the most interesting about caproic acid is its chemical name which comes from the word capra that is Latin for goat. This is because, C6 smells and tastes like goats. However, there is no need to worry about the taste as the smell and flavour is removed when processed.

One of the negative effects of Caproic acid would be that it causes digestive issues when consumed even in small doses which will affect your stomach. Hence why it is important to find MCT Oils that are great in quality. Low quality MCT oils usually may contain about 1- 2% of C6.


Caprylic Acid (C8)

Caprylic Acid also known as C8 which is the good type of MCT that brings you the benefits you’re looking for. It has 8 carbon molecules in it and is able to convert ketones in your body in minutes. This makes C8 MCT Oil great at suppressing hunger as well as fuel your body and brain throughout the day which can help avoid the risk of feeling foggy and tired.
One of the good things to C8 is that it is flavourless, odourless and is easy on your stomach unlike C6 that has a goat taste, smell and causes stomach discomfort.


Capric Acid (C10)

Capric acid has 10 carbon molecules to it however it is less efficient in your body as compared to C8. With the extra 2 carbons, the liver in your body will need a longer time to convert it into ketones. Your body will still be able to get the benefits of MCT Oils helping metabolism and brain function but converting ketones will just take a longer time.

C10 is more common than C8 which makes it cheaper to produce. This is why some products have a blend of C8 and C10 to make the product cheaper.


Lauric Acid (C12)

Lauric Acid is one of the cheapest type of MCT Oil as it has lots of coconut oil. However, a biochemist would argue that lauric acid is not an MCT Oil as it behaves like a long chain fatty acid. The extra carbons in it means your body needs to work more which means your lover is less efficient in absorbing it. Absorbing C12 is also difficult especially if you are not on a proper diet as it is only able to be broken down into ketones if you are on a very low carb diet.
