    ◉ C8 MCT creates 4 X ketones versus other MCTs like C10 and C12.

    ◉ Mixed MCT oils contain a mix of MCTs including C8, C10 and C12.
    ◉ Because mixed MCT oils contain less C8, they boost ketone levels by less.

Jane Cohen
Securely packaged and arrived on time

The oil arrived safely on time and securely packaged. It is pleasant to take by the spoon.

Value for money

As a Pensioner, I tend to look for the best available within my budget and at the present time this fits the bill, although the Bottle is not that easy to dispense from, a bottle with a pourer would be more useful as was the case on my previous oil, so I transfer it into the "old" container, so for anyone that see's my oil in the kitchen, it's not your bottle they see!

    You can take one dose several times per day. It's best to space these out by 4 hours or more.

Have a Question About Pure C8 MCT Oil?

Our keto and fasting experts are here to answer any questions you might have.


How does C8 MCT oil work for fat loss?

C8 MCT oil turns into ketones when you take it. And when you take C8 MCT oil an hour before a meal, you have enough ketones to reduce your appetite at that meal.

When your appetite is reduced, you eat less at mealtimes and take in fewer calories over the day. This helps you to lose fat over time.

Will C8 MCT oil cause stomach upset

Stomach symptoms (ache, pain, loose stools, diarrhoea) are common with all MCT oils.

Scientific research studies show up to 40% of people experience them with a 20ml dose.

It isn’t yet clear in research why. But there is evidence it may be linked to dose size, time getting used to the oil, the dosage protocol used and an individual person’s general stomach condition or microbiome.

In our 8 years experience, it is clear that far fewer people experience symptoms with Ketosource Pure C8 MCT Oil. Only 0.36% of our clients report stomach symptoms. This may be due to our oil’s purity and our tried and tested dosing protocol.

Takeaway: Please make sure to use the dosing instructions from the packaging to avoid stomach upset.

  1. Start with one teaspoon only.
  2. Only increase your dose each week if your stomach feels okay.
  3. In case of stomach ache or loose stools. Fix it by following these three steps: A) Reduce dose to ½ teaspoon only.
    B) Take it with fibre (e.g. acacia fibre).
    C) Send us a message to get our help. We will fix any remaining issues and help you increase to normal dose safely.

How much palm kernel oil is in C8 MCT oil?

100% of Ketosource Pure C8 MCT Oil comes from sustainably farmed coconut oil.

We don't use any palm oil or palm materials to make Pure C8 MCT Oil.

What method is used to extract the C8 MCT Oil?

For the Pure C8 MCT oil, a minimal process has been used to extract the C8 from its original sources. No solvents are used for the extraction. The process involves combining steam, active carbon, bleaching earth and glycerine with a capric or caprylic acid MCT oil input. It's primarily using 'high surface' area binders to ensure our purity standards.

If you've used activated charcoal (active carbon) before as a supplement, it's the same idea. The parts of the oil and any impurities get bound to the high surface area, by active carbon and bleached earth (terrible name - a lot less insidious than it sounds).

Bleaching earth is comparable to things like bentonite clay in function. These then pass through filters that collect the aggregated bound parts of the input, leaving the C8 to filter out alone.

I’m on a calorie controlled diet. Can I use C8 MCT oil as well or is it only for keto diets?

C8 MCT oil will work when following any diet. This is because C8 MCT oil helps reduce your appetite. And it can do this without you changing your diet. This helps you eat less at your meals, regardless of what you eat.

Should I use C8 MCT oil in bulletproof coffee?

You can use C8 MCT oil in your bulletproof coffee but it lessens the benefit of the oil. If your goal is fat loss you should avoid adding it to your bulletproof coffee altogether.

Bulletproof coffee is great for other goals, but not fat loss. In fact, bulletproof coffee is likely to contribute to weight gain.

How should I store C8 MCT oil?

The best place to keep your C8 MCT oil is in a cool dark place like a cupboard. That way it will stay pourable whenever you need it. It is not necessary to keep the oil in the fridge.

Your C8 MCT oil is very stable and does not need to be stored in the fridge. Like most oils when refrigerated it turns from a liquid to a solid state.

Can I put C8 MCT oil in hot drinks?

Heat can impact the C8 MCT oil. But putting it into hot drink such as coffee, tea or herbal tea is completely fine. Especially if those drinks have zero calories. That is a very popular way to use it.

C8 MCT oil has a smoke point of 160 degrees celsius. So as long as you avoid cooking or frying the C8 MCT oil, the heat won't negatively impact it.

Does it contain Lauric Acid (C12)?

This product contains no lauric acid as it is designed to be a pure source of C8 MCT (Caprylic Acid). The Lauric Acid (also known as C12) has been completely removed.

For clarification on this you can check the nutrition facts label on this page. It shows lists C12 (Lauric Acid) as 0g per 100g.

We remove all C12 (and C10) from Pure C8 MCT Oil. This is because neither are effective at boosting ketones. Lauric Acid has a particularly low impact on ketones - so this is also removed from our other product, Pure MCT Oil.

What is the shelf-life once opened? How long will it last?

Each bottle of C8 MCT oil comes with a best before date on the package.

Food regulations require that the item have a best before date but its shelf life is far longer than the Best Before Date.

This is because the oil is a very stable fatty acid. It doesn't damage easily. Opening the bottle or keeping it at room temperature has no impact on it's shelf-life.

So you can safely use the C8 MCT oil long past its best before date. If your bottle is over one year after the best before date, please contact us to discuss further.

Can I use C8 MCT oil for something other than fat loss?

Yes, C8 MCT oil has been linked to various health benefits.

Here at Ketosource we are focused on fat loss. But we have collected some interesting research on various other topics. These include type 1 & 2 diabetes, cancer, Alzheimer's disease, physical endurance and more.

You can get in touch with our Nutrition Analysts via our contact page to find out if we have some extra resources for you.

Can I use C8 MCT oil if I'm pregnant?

I have not seen anything to suggest that C8 MCT oil could be dangerous while pregnant.

But I'm afraid I cannot be 100% certain until I’ve seen research on it. So it’s best to speak with your doctor to be sure.

My dog has epilepsy. Can I give them C8 MCT oil?

There is some research to support the use of C8 MCT oil to support humans and canines with epilepsy.

If you write to us here and let us know your dog's weight, age and if they are neutered one of our nutritional analysts will get back to you.

We would love to help your pup feel better.

What is the difference between Pure C8 MCT Oil and Pure MCT Oil?

Pure C8 MCT Oil and Pure MCT Oil both contain C8 MCT.

The only difference is that Pure C8 MCT Oil has more C8 MCT per ml than Pure MCT Oil.

In the research C8 MCT helps with fat loss by giving you appetite-reducing ketones. So you’ll need more Pure MCT Oil per dose than Pure C8 MCT Oil to get the same amount of ketones.
