MCT Oil vs Coconut Oil: What Is the Difference and Which Should You Choose?
Want to choose MCT oil but some people recommend coconut oil instead? MCT oil and coconut oil are related yet fundamentally different products — MCT oil is extracted from coconut oil through a fractionation process that isolates and concentrates only medium-chain triglycerides (primarily caprylic acid C8 and capric acid C10), whereas coconut oil is a whole, unrefined oil containing a broad mixture of fatty acids [1,2]. The key difference is that MCT oil contains 100% medium-chain triglycerides, whilst coconut oil contains only about 54% MCTs, most of which is lauric acid (C12) — a fatty acid that metabolically behaves more like a long-chain fat than a true MCT [2,3]. Want to choose MCT oil over coconut oil for maximum ketogenic benefit? The choice between these products depends primarily on your supplementation goal: MCT oil dominates in the context of ketosis, energy, and problematic-skin care, whilst coconut oil performs better in the kitchen and for body moisturising. If you want to choose MCT oil wisely, the guide below presents a detailed comparison of both products across all their key applications.
What will you learn from the article?
Is MCT Oil the Same as Coconut Oil?
No — MCT oil and coconut oil are related but fundamentally different products in terms of composition, metabolism, and applications [1,2]. MCT oil is extracted from coconut oil (or palm kernel oil) through a process called fractionation, which isolates and concentrates only medium-chain triglycerides — primarily caprylic acid (C8) and capric acid (C10), the most metabolically active components.
Coconut oil is a whole, unrefined (or minimally refined) oil pressed from coconut flesh. It contains a broad mixture of fatty acids: approximately 50% lauric acid (C12), plus smaller amounts of C8, C10, and various long-chain fatty acids (C14, C16, C18) [2,3].
The key metabolic difference is that MCT oil contains 100% medium-chain triglycerides, whilst coconut oil contains only about 54% MCTs, most of which is lauric acid — a fatty acid that metabolically behaves more like a long-chain fat than a true MCT — it is absorbed via the lymphatic system rather than directly to the liver through the portal vein [1,3]. So although MCT oil comes from coconut, it is a concentrated, purified supplement designed for maximum ketogenic efficiency — not simply “coconut oil in a different bottle.”
Did you know that… to obtain the same amount of fast-acting C8+C10 fatty acids as from one tablespoon of pure MCT oil, you would need roughly 7–8 tablespoons of coconut oil? Importantly, that would add over 800 extra calories to your diet [2,3].
What Are the Key Differences Between MCT Oil and Coconut Oil?
The following side-by-side comparison shows the differences between MCT oil and coconut oil across all major factors relevant to choosing the right product for your needs [1,2,3].
Composition: MCT oil contains up to 100% C8 and C10 fatty acids; coconut oil contains ~50% lauric acid (C12), ~7% C8, ~6% C10, plus long-chain fats.
Metabolism: MCT oil is absorbed directly into the portal vein and sent to the liver for immediate conversion into ketones — without requiring bile or pancreatic enzymes [1,3]. The lauric acid in coconut oil is packaged into chylomicrons and follows the slower lymphatic pathway, circulating in the blood for many hours before reaching the liver.
Ketone production: MCT oil produces significantly more ketones, significantly faster — within 30–60 minutes of consumption [3,4]. Coconut oil produces some ketones but far less efficiently.
Physical state: MCT oil is liquid at room temperature, tasteless, and odourless. Coconut oil is solid below ~24°C with a mild coconut flavour and aroma.
Smoke point: coconut oil ~177°C — suitable for medium-heat cooking. MCT oil ~150°C — not suitable for cooking; best added to dishes or beverages.
Caloric density: nearly identical (~120 kcal per tablespoon).
Price: MCT oil is typically 3–5× more expensive per ml than coconut oil owing to the fractionation process [2].
How Much MCT Is Actually in Coconut Oil?
Coconut oil contains approximately 54% medium-chain triglycerides by weight; however, composition matters more than total percentage — the dominant fatty acid is lauric acid (C12), accounting for about 47–50% of total fat, which fundamentally affects the product’s metabolism [2,3].
Although lauric acid is technically classified as a medium-chain fatty acid by carbon-atom count, it is metabolised primarily via the lymphatic system — like a long-chain fat — not through the rapid portal-vein pathway characteristic of MCTs such as C8 and C10 [1,3]. This metabolic difference is crucial for understanding why coconut oil cannot replace MCT oil in the context of ketosis.
The truly “fast” MCTs in coconut oil — C8 (caprylic acid) at ~7% and C10 (capric acid) at ~6% — account for only about 13% of coconut oil’s total fat content. This means you need roughly 7–8 tablespoons of coconut oil to obtain the same amount of C8+C10 as from one tablespoon of pure MCT oil — adding around 800–1,000 extra calories in the process [2,3]. This is precisely why MCT oil was developed as a distinct product. A pure C8 MCT oil delivers the most concentrated form of the fastest-acting fatty acid found naturally in coconut oil.
Which Is Better for Keto — MCT Oil or Coconut Oil?
For ketogenic diets, MCT oil is significantly more effective than coconut oil — the concentrated C8 and C10 fatty acids in MCT oil are rapidly converted into ketones by the liver, providing a measurable rise in blood ketone levels within 30–60 minutes of consumption [3,4]. Research shows that the ketogenic effect of C8 is three times higher than C10 and six times higher than C12 (the lauric acid dominant in coconut oil).
This makes MCT oil an effective tool for maintaining ketosis, particularly during the metabolic-adaptation phase or after accidental carbohydrate intake exceeding your diet’s limit. Coconut oil supports ketosis to some extent — its small C8 and C10 content produces ketones, and even lauric acid eventually contributes to ketone production — only far more slowly via the lymphatic route [1,3].
However, to achieve the same ketogenic effect as 1 tablespoon of MCT oil, you would need to consume considerably more coconut oil — adding significant extra calories (800–1,000 kcal) that could undermine weight-loss efforts [2,4]. For advanced keto practitioners focused on sustained long-term ketosis, MCT oil is the clear winner. Coconut oil can complement a keto diet as a cooking fat but should not be the primary ketone source.
MCT Oil vs Coconut Oil for Cooking — Which Should You Use?
Coconut oil is the better choice for cooking owing to its higher smoke point (~177°C / 350°F), which makes it suitable for frying, baking, and roasting [2,5]. Its solid state at room temperature also makes it useful as a butter substitute in baking recipes.
Heating MCT oil above its smoke point (150°C) initiates fatty-acid oxidation — a degradation process that creates aldehydes and free radicals. Therefore, use MCT only cold or in dishes below 100°C [5]. MCT oil is best used unheated: as an addition to coffee, smoothies, salad dressings, or drizzled over cooked dishes after preparation.
MCT Oil vs Coconut Oil for Skin and Hair?
The lauric acid in coconut oil has a comedogenicity rating of 4 on a 5-point scale, meaning a high risk of clogging pores. It also serves as a food source for the yeast Malassezia furfur, which triggers fungal acne (Malassezia folliculitis) and seborrhoeic dermatitis [7]. The C8 and C10 acids in MCT oil have a rating of 0–1 — safe even for acne-prone skin.
| Application | MCT Oil (C8+C10) | Coconut Oil |
|---|---|---|
| Face | Best — non-comedogenic | May clog pores |
| Body | Good | Excellent |
| Hair | Lightweight | Excellent as a mask |
| Fungal acne | Safe | Worsens condition |
| Pore-clogging | Does not clog | Comedogenic |
MCT oil is ideal for use on the face and problematic skin, whilst coconut oil works well on the body and hair.
Did you know that… lauric acid (C12), which makes up half of coconut oil, has significant commercial value beyond dietary supplements? It is a key ingredient in the production of soap, shampoos, and cosmetics, which is why it is removed during fractionation — but not wasted [2].
Is MCT Oil Worth the Extra Cost Over Coconut Oil?
The answer depends on your primary goal — MCT oil typically costs 3–5× more per ml than coconut oil owing to the fractionation process [2].
For ketosis, energy, and cognitive benefits: definitely yes — MCT oil delivers far more active fatty acids per serving, making it more cost-effective on a “per ketone” basis [3,4].
For cooking and body moisturising: it depends on your goals — both oils differ in specifics, smoke point in the kitchen; in the context of body moisturising, everything depends on your skin’s needs and sensitivity [2,5].
For skin conditions (acne, fungal issues): absolutely yes — the non-comedogenic properties of MCT oil make it the only “safe” option in this comparison [6,7].
Most users benefit from both oils — MCT as a supplement and coconut oil as a kitchen product. Browse our range of pure MCT oil supplements to get concentrated C8+C10 benefits.
How Is MCT Oil Made from Coconut Oil?
MCT oil is produced through a process called fractionation, which isolates specific fatty acids from raw coconut oil [1,2]:
Step 1: Raw coconut oil is heated — to separate fatty acids by chain length.
Step 2: Long-chain fatty acids (C14, C16, C18) solidify first and are removed.
Step 3: Lauric acid (C12) is separated and isolated for other production purposes (it has value in soap and cosmetics manufacturing).
Step 4: What remains is a concentrated liquid of C8 and C10 — pure MCT oil.
Some MCT oils undergo an additional step to isolate only C8 MCT (depending on production specifications and product formulation) [3]. The fractionation process explains why MCT oil is always liquid, tasteless, and odourless.
MCT Oil vs Olive Oil — How Do They Compare?
MCT oil and olive oil serve entirely different nutritional roles and are complementary, not competitive [5,8]:
| Feature | MCT Oil | Coconut Oil | Olive Oil |
|---|---|---|---|
| Heart health | Neutral | Neutral | Best |
| Ketone production | Best | Moderate | None |
| Cooking | Low smoke point | Good | Best |
| Skin care | Face | Body | Moderate |
Olive oil is rich in monounsaturated fats and polyphenols — widely regarded as the healthiest oil for the heart [8]. MCT oil provides medium-chain saturated fats rapidly converted into ketones. The best approach: olive oil as your primary dietary fat, MCT oil as a supplement for energy.
What Is MCT Oil and How Is It Different from Other Oils?
MCT oil (medium-chain triglycerides) is a concentrated dietary supplement containing C8 and C10 fatty acids extracted from coconut or palm kernel oil through a fractionation process [1,2]. Unlike whole culinary oils (coconut, olive, avocado), MCT oil is a purified product designed for rapid absorption and ketone production. The key difference lies in the metabolic pathway: MCTs bypass the lymphatic system and travel directly to the liver via the portal vein, where they are immediately converted into ketones — primarily beta-hydroxybutyrate (BHB), the preferred fuel for the brain and muscles during ketosis [1,3].
Understanding what sets MCT oil apart from other dietary fats helps explain why it works differently and why it exists on the market as a distinct product from coconut oil. Learn everything about what MCT oil is, how it is made, and all its uses.
Can You Cook with MCT Oil?
Yes, although it is not recommended because MCT oil has a decidedly lower smoke point than coconut oil and is not ideal for high-heat cooking — it can be safely used only in low-temperature applications and added to dishes after cooking without damaging the fatty-acid profile [5].
There are practical ways to incorporate MCT oil into meals without risking degradation of active components, such as: bulletproof coffee, protein shakes, salad dressings, drizzling over finished dishes, no-bake recipes, and gentle warming on very low heat. When cooking with MCT oil, the most important thing is to avoid heating the product above 150°C, as this degrades the C8 and C10 fatty acids and promotes unpleasant flavours and odours.
