Best MCT Oil: C8, Benefits, Disadvantages & Nonsense

MCT oil has become one of the most talked-about supplements in the worlds of fitness, keto, and brain health. But between all the marketing buzz and contradictory claims, it’s hard to know what’s real, what’s exaggerated, and which type is actually best.

Here’s everything you need to know about MCT oil, with a special focus on C8 MCT oil — plus its advantages, disadvantages, and the common nonsense you can ignore.

1. What Is MCT Oil?

MCT stands for medium-chain triglycerides — a type of fat made up of medium-length fatty acids. They’re found naturally in:

• Coconut oil

• Palm kernel oil

• Dairy products (in smaller amounts)

Because of their shorter chain length, MCTs are digested more quickly than long-chain fats, making them a quick source of energy.

2. Different Types of MCTs

MCT oil can contain a mix of these fatty acids:

• C6 (Caproic acid) – Rare, strong taste, can cause stomach upset

• C8 (Caprylic acid) – Fastest energy conversion, most sought-after for supplements

• C10 (Capric acid) – Slower than C8, but still quick to absorb

• C12 (Lauric acid) – Borderline long-chain; acts more like a typical fat in digestion

💡 Pure C8 MCT oil is considered premium because it converts to energy quickly and is less likely to cause digestive discomfort than blends with C6 or high C12.

3. Benefits of C8 MCT Oil

• Quick energy source – Rapidly metabolized in the liver

• Keto-friendly – Supports ketosis without carbs

• Neutral taste & smell – Easy to add to coffee, smoothies, or salad dressings

• Easier digestion – Compared to blends with C6 or high C12

4. Disadvantages of MCT Oil

• Cost – Pure C8 MCT oil is more expensive than blends

• Potential digestive upset – Large doses can cause loose stools or cramping

• Not a magic bullet – Won’t replace balanced nutrition or exercise

• Calorie-dense – About 115 calories per tablespoon, so it adds up quickly

5. MCT Oil Myths & Marketing Nonsense

• "MCT oil will make you lose weight instantly" – It can be part of a diet strategy, but without calorie control, fat loss won’t happen.

• "C8 MCT boosts IQ" – No evidence supports cognitive “superpowers” — it may provide a clean energy boost, but it’s not a brain-altering miracle.

• "More MCT = more results" – Overdosing can cause digestive distress and won’t deliver extra benefits.

• "C12 is the same as C8" – Lauric acid (C12) acts differently and is slower to metabolize, so the two aren’t interchangeable.

6. How to Choose the Best MCT Oil

• Go for pure C8 if you want maximum fast energy conversion

• Check sourcing — coconut-derived MCT is generally more sustainable than palm

• Look for lab testing — ensures purity and no unwanted additives

• Avoid unnecessary flavorings if you want versatility

💡 For pure, high-quality C8 MCT oil, look for brands that are cold-processed, lab-tested, and 100% coconut-derived. AuraFuel C8 MCT Oil is an example of a premium choice for those seeking quick energy without fillers.

7. How to Use MCT Oil

• Add 1 tsp to morning coffee or tea (increase gradually to 1–2 tbsp)

• Blend into smoothies for sustained energy

• Use in salad dressings or drizzle over meals for extra healthy fats

• Avoid cooking at high heat — MCT oil has a low smoke point

Final Thoughts

The best MCT oil for most people is pure C8, thanks to its quick absorption, neutral taste, and gentler digestion compared to blends.

That said, MCT oil isn’t a miracle product — it’s simply a fast, convenient energy source that works best when paired with a healthy, balanced diet.

If you want to avoid the nonsense and choose a product that’s worth your money, go for lab-tested, coconut-derived C8 MCT oil from a trusted brand.
