Organic C8 MCT Oils

What is the difference between C8 MCT oil and a C8 + C10 blend?

C8 MCT oil names one fatty acid on the label, caprylic acid with eight carbon atoms. A C8 + C10 blend names capric acid as well, ten carbon atoms instead of eight, and in our bottles the two are mixed at 60% C8 to 40% C10.

On price the blend is the cheaper line: a 15 ml serving costs £0.42 from the litre bottle, against £0.51 from the litre of pure C8. If two acids suit you better than one, the C8 + C10 MCT oil has its own page.

Both lines taste neutral and both carry 135 kcal and 0 g of carbohydrate per 15 ml serving. The choice comes down to the ingredient list and to the price per serving, not to the nutrition table.

What is the best C8 MCT oil in the UK?

No C8 oil can be called the best one, so compare four things on the label. The declared share of caprylic acid, the source of the fat, the organic certification and the price per serving cover most of what separates one bottle from another.

Declared purity is where the market splits. British labels run from 95% and 97% caprylic acid up to 100%, and these bottles name caprylic acid as the only ingredient, with nothing else in the list.

Source comes second. All four products on this page, the three oils and the C8 powder, name coconut as the origin of their caprylic acid. Palm kernel oil is the other raw material the MCT trade works with, and it appears on labels elsewhere.

Certification is the fourth line worth reading, and on this page it is not uniform: Organic sits in the name of the three bottles, while Fat Expert Powder is a powder rather than an oil and does not carry it.

How do you use pure C8 MCT oil?

A serving is 15 ml of oil, stirred into coffee, shakes, yoghurt, soup or a salad dressing. The oil tastes neutral, so it takes on the flavour of whatever it goes into.

A sensible way to begin is 5 ml rather than the full 15 ml, building up over a week or two. Most people settle at one 15 ml serving a day, taken with food rather than on an empty stomach.

Warm drinks and a quick blend mix the oil in most evenly, while in a cold glass it tends to sit on the surface. In a dressing it behaves like any other liquid oil and wants shaking with vinegar or lemon juice.

The 100 ml bottle holds six servings, which makes it the size for a desk drawer or a bag, while the litre is the kitchen bottle at 66 servings.

What does C8 MCT oil cost per serving?

A 15 ml serving costs £0.51 from the 1000 ml bottle and £0.75 from the 500 ml bottle. The 100 ml bottle comes to £0.82 per serving and costs £4.90, which makes it the size to try first.

Per 100 ml the same gap reads £3.39 for the litre against £4.98 for the half litre, so the large bottle takes about a third off the price of the identical oil.

Frequently asked questions

What does C8 MCT oil do?

No health claim for MCT is authorised in Great Britain, so we list no benefits. C8 MCT oil is a pure fat with 900 kcal per 100 ml that people stir into coffee, shakes and dressings. We describe what is in the bottle, not what it will do for you.

Is C8 MCT oil the same as MCT oil?

MCT oil in the UK is coconut fat made of medium-chain fatty acids, most often caprylic acid (C8) together with capric acid (C10). C8 MCT oil is the version that names caprylic acid on its own, so every C8 oil is an MCT oil, while not every MCT oil is a C8 oil.

What is the downside of MCT?

Taken in large amounts at once, C8 MCT oil can cause stomach upset, loose stools or nausea. A first serving of 5 ml instead of the full 15 ml, taken with food, makes the first week easier. Our article on MCT oil side effects goes through them one by one.

What happens if I take MCT oil every day?

A daily 15 ml serving adds 135 kcal and 0 g of carbohydrate to the day. It counts towards the day's fat and energy rather than sitting outside it, which matters if you weigh or log what you eat.

Is C8 MCT oil made from coconut?

Yes, coconut is the declared source on all four products on this page, the three oils and the C8 powder. We read each label separately rather than assuming it.

Is BeKeto C8 MCT oil organic?

Organic certification covers the three bottles of 100 ml, 500 ml and 1000 ml, which carry Organic in the product name. Fat Expert Powder does not carry it, and it is a powder rather than an oil.

Can you use C8 MCT oil on your hair?

These bottles are food, not cosmetics. We sell them for the kitchen rather than for hair or skin, and the label carries a nutrition table rather than cosmetic directions.

Is C8 MCT oil suitable for vegans?

The oils name caprylic acid from coconut and nothing else, so the bottles carry no ingredient of animal origin. Fat Expert Powder is the exception on this page, because that powder is made with milk protein and peanut butter.

Where can you buy C8 MCT oil in the UK?

BeKeto ships C8 MCT oil across the UK with free delivery on orders from £59, so you do not need a shop near you. Health food shops and pharmacies on the high street stock C8 oils too.
