Which MCT oil is actually worth buying in the UK?
Because here’s the thing. The market is absolutely rammed with options, and not all of them deliver what they promise on the label. Some use cheap C12 lauric acid and dress it up as MCT oil. Others arrive in plastic bottles, which is not ideal for storing a fat-based liquid. A few even leak in the post, which is a particularly grim surprise.
We’ve been through most of them so you don’t have to.
At the Keto Collective, we’ve tested, tried, and (occasionally regretted) a fair few MCT oils over the years. What follows is our honest shortlist of the best MCT oils available in the UK right now, with no waffle and no filler.
Let’s get into it.
The Best MCT Oils in the UK for 2026
Before we get to the picks, a quick word on what to look out for.
Quality sourcing matters. Organic coconuts, clearly stated C8 and C10 percentages, no solvents, no hexane. Glass bottles where possible. And if a product is vague about its fatty acid breakdown, that’s usually a sign to move on.
If an MCT oil leans heavily on C12 (lauric acid) without being upfront about it, give it a miss. C12 is not efficiently converted into ketones the way C8 and C10 are. You’d essentially be paying MCT prices for something closer to coconut oil.
Right. Here are our top picks.

Another Top Hunter & Gather MCT oil product, this time their Pure C8 Organic MCT Oil, (#ad) which contains 100% caprylic acid from organic coconuts to maximize ketone production.
For those willing to pay slightly more more to get a cleaner hit of MCT oil, The C8 MCTs boost ketones up to 3X more than other MCT oils, making it ideal for keto, paleo, vegan and gluten-free lifestyles.

Natures Aid 100 Percent MCT Oil
Natures Aid 100% MCT Oil (#ad) provides a clean, pure source of medium chain triglycerides while also being a cheaper alternative to other more expensive MCT oils. The oil is manufactured in the UK to quality standards and is suitable for vegans.
One thing we aren’t happy about is they have changed from a glass bottle to plastic, which is not great for storing a fat-based liquid (or for the environment).
It may be worth spending a little more to get a higher-quality product.
Pros
- Cheap option for new users that want to experiment with MCT oil.
- Made in the UK to GMP and Pharmaceutical Standards
- Unflavoured and odourless, ideal for use in coffee, shakes, dressings and smoothies
Cons
- Packaging may vary
- May not be suitable for those who don’t like the taste of coconut oil
- The amount of C8 (Caprylic acid) in this product is 52g, which is low.
Ketosource Pure C8 MCT Oil
Ketosource Pure C8 MCT Oil (#ad) is another high-quality product that promises a maximum ketone boost, increasing ketones up to 4X more than other low-quality MCT oils!
- Increases ketones 3 times more than C10 MCT
- All-natural and non-allergenic with the highest standards certification
Eat Wholesome Organic Coconut MCT Oil
We recently tried the Eat Wholesome Food Co. Organic Coconut Oil, (#ad) and we were impressed with the quality of the product. We also appreciate that it comes in a CO2-neutral glass bottle, which is better for the environment.
However, the bottle design is poor and it can dribble when poured, which is a nightmare when MCT costs so much!
Some users have reported that the label is misleading and it’s not a pure C8 oil, so it’s worth doing your research before making a purchase.
- Made with 100% organic coconut oil and high C8
- Comes in a CO2-neutral glass bottle
- The bottle design is poor and it can dribble when poured
- Not the cheapest option on the market
- Some users have reported that the label is misleading and it’s not a pure C8 oil
Cocofina Organic MCT Oil
Cocofina Organic MCT Oil (#ad) is small batch ethical and gluten-free, with no monkey business of any kind, including exploiting humans or animals. And we love that at the Keto Collective!
Cocofina Organic MCT Oil is perfect for those on a keto diet, and seems to be a little easier to stomach than many of the other oils on the market. The only issue is that it is VERY expensive! It comes in a 250ml bottle instead of the typical 500ml, so make sure you are aware of that!
- It’s organic, palm oil-free, and extracted from sustainably grown GM-free organic coconut oil without the use of chemicals.
- It’s kind on the stomach and can be used to make bulletproof coffee, protein shakes, dressings, and smoothies.
- Some users have reported leakage during delivery.
- It’s relatively expensive compared to other MCT oils.
- Comes in a smaller 250ml bottle.
MCT Oil UK Buying Guide
When looking to buy the best MCT oil in the UK, there are several factors to consider. Here are some of the key features to look out for:
Best MCT Oil Quality and Purity
The quality and purity of MCT oil are crucial when choosing the best product. Look for MCT oil that is derived from high-quality sources and has undergone rigorous testing to ensure purity. Check for certifications such as GMP, ISO, and organic certifications.
Type of MCT Oil
There are four types of MCT oil, namely C6, C8, C10, and C12. C8 (caprylic acid) and C10 (capric acid) are considered the best types of MCT oil as they are quickly metabolized and provide the most energy. Look for MCT oil that contains high levels of C8 and C10.
Be wary of any MCT oil which promotes C12 as the main ingredient as that will NOT help you with getting into ketosis!
Where possible opt for an Organic MCT oil.
Packaging
MCT oil is sensitive to light and heat, which can cause it to go rancid quickly. It’s best to choose MCT oil that comes in a dark glass bottle to protect it from light. Also, ensure that the bottle is airtight to prevent oxidation.
Best MCT Price
MCT oil prices can vary significantly depending on the brand and quality. While it is tempting to go for the cheapest option, it is essential to consider the quality and purity of the oil. Look for a balance between price and quality. You definitely don’t want to go with cheap MCT oil that doesn’t actually help you reach or maintain ketosis!
Expect to pay a little more for pure C8 MCT oil.
Serving Size and Dosage
Consider the serving size and dosage of the MCT oil before making a purchase. Look for products that provide clear instructions on how to use the oil and the recommended dosage. Also, consider the serving size and how long a bottle will last. Some MCT oils come in smaller bottles, so make sure to weigh up your options and do your maths before clicking buy.
Finally On… The Best MCT Oils in The UK
If you’re after an everyday MCT oil that genuinely delivers, the Hunter & Gather Premium Organic C8 & C10 blend is the one we come back to time and again. Good sourcing, clean distillation, proper labelling. It ticks every box.
For anyone who wants maximum ketone output, particularly around training, the Pure C8 version is worth the extra spend. It’s cleaner, faster, and honestly one of the best MCT products we’ve come across on the UK market.
