Product Highlights
About C8 MCT (Caprylic Acid)
Caprylic acid (octanoic acid, designated C8:0 because it has an 8-carbon chain) is one of several medium-chain triglycerides (MCTs) found naturally in coconut oil. Coconut oil naturally contains a mixture of MCTs with different chain lengths:
- C6 (caproic acid) — very short chain, can cause digestive discomfort
- C8 (caprylic acid) — the most metabolically efficient MCT for ketone body production
- C10 (capric acid) — metabolised more slowly than C8
- C12 (lauric acid) — technically a long-chain fatty acid in some metabolic classifications, less efficient for rapid ketone conversion
This product uses only C8 (caprylic acid) — isolated from the full MCT spectrum found in coconut oil. The result is a single-fatty-acid product with consistent metabolic pharmacokinetics.
Blood Ketone Levels After Ingestion: C8 vs C8+C10 Pharmacokinetics
The chart below shows the time-course of blood ketone (β-hydroxybutyrate) levels following ingestion of pure C8 MCT compared to a C8+C10 MCT blend. Pure C8 shows a faster onset and higher peak than the C8+C10 combination — a documented pharmacokinetic difference between the two fatty acid profiles.
Note: Ketone levels shown reflect blood β-hydroxybutyrate measurements after fatty acid ingestion. Individual responses to MCT fatty acids vary based on diet, fasting state, and metabolic context.
Pure C8 vs C8+C10 MCT Blends
Many MCT products on the market use a blend of C8 and C10 fatty acids rather than pure C8. Here’s how the two compare across factual product characteristics:
| Feature | Pure C8 MCT Powder | C8+C10 MCT Powder |
|---|---|---|
| Absorption | C8 has the shortest chain length used in MCT products, with faster absorption pharmacokinetics | C10 has a longer chain length than C8, with slower absorption pharmacokinetics |
| Digestive Tolerance | Higher purity C8 may cause digestive discomfort in some individuals due to rapid absorption. Starting with a small dose and gradually increasing is recommended. | The blended C8+C10 profile may be gentler on the digestive system due to slower overall absorption. |
| Ketone Production Profile | Faster ketone onset and higher peak ketone levels (see chart above) | Slower ketone onset and lower peak ketone levels (see chart above) |
| Cost | Pure C8 isolation is more complex, resulting in a higher product cost | Blended C8+C10 products are typically more cost-effective |
| Best For | Users prioritising the specific fatty acid profile of C8 and willing to start with a small dose | Users prioritising general use and broader tolerance |
MCT Powder vs MCT Oil
MCT products come in two main formats: liquid oil and powder. Both deliver MCT fatty acids, but each format has practical differences:
| Feature | MCT Powder (with Acacia Fibre) | MCT Oil |
|---|---|---|
| Portability | Travel-friendly — no liquid restrictions, no leakage risk, easy to carry | Liquid bottle — subject to airline restrictions, leakage risk |
| Digestive Tolerance | The acacia fibre component may help mitigate digestive discomfort that some users experience with pure liquid MCT oil | Some users experience digestive discomfort with pure liquid MCT oil, particularly at larger doses |
| Texture & Mixability | Creates a creamy texture in hot beverages. Mixes well into both liquids and dry goods without separating. | Can separate from beverages, particularly when not blended. Greasier mouth-feel. |
| Composition | Approximately 70% MCT + 30% non-digestible acacia fibre | 100% MCT fat |
| Versatility | Versatile — works in coffee, tea, smoothies, baking, dry mixes, sprinkled on foods | Best for liquid use. Less suited to dry-good applications. |
About Acacia Fibre
Acacia fibre (gum arabic) is a soluble dietary fibre extracted from the stems and branches of Acacia senegal and Acacia seyal trees, which are native to North Africa. It is a well-established food ingredient recognised globally.
Acacia fibre is non-digestible — it passes through the upper gastrointestinal tract intact and reaches the large intestine, where it functions as a fermentable substrate for gut bacteria during their normal metabolic activity.

Directions for Use
Start with 1 teaspoon (~5g) added to your coffee, matcha, hot cacao, smoothie or shake. Stir or blend to mix.
Gradually increase to 1–2 tablespoons (10–20g) per day as tolerance develops. Most users find 1 tablespoon (10g) per day works well.
Versatile uses: coffee creamer, smoothie base, baking ingredient, sprinkled into dry food preparations, mixed into protein shakes.
Store in a cool, dry place. Use within 6 months of opening for best quality.
Good to Know
Does it taste like coconut?
No. The product is tasteless and odourless — the caprylic acid (C8) isolation process produces a neutral-flavour MCT that doesn’t carry coconut notes through to the finished product.
Will it cause digestive discomfort?
Some people experience mild digestive discomfort when first introducing MCTs, particularly at larger doses. Starting with a small amount (1 teaspoon) and gradually increasing over 1–2 weeks helps the digestive system adjust. The acacia fibre component may help with tolerance compared to pure liquid MCT oil.
Is it suitable for baking?
Yes. Unlike liquid MCT oil, the powder format works in dry-good applications including keto-friendly baking, sprinkled onto foods, or mixed into dry protein shake powders.
Why is C8 more expensive than blended MCTs?
Coconut oil naturally contains a mixture of fatty acids. Isolating pure C8 (caprylic acid) from the broader MCT spectrum requires additional fractionation, which increases production cost. Blended C8+C10 products skip this step.
Is acacia fibre a filler?
No. Acacia fibre serves two functional roles: it acts as the carrier that allows the MCT (which is naturally a liquid fat) to be in powder form, and it is itself a beneficial prebiotic soluble fibre. Other MCT powders often use maltodextrin or sodium caseinate as carriers — those are functional but less nutritionally beneficial than acacia fibre.
Important Information
This product is supplied as a food ingredient and is intended for use as part of a varied, balanced diet and a healthy lifestyle. Adult use only.
Start with a small amount and increase gradually. Introducing MCTs too quickly may cause temporary digestive discomfort (loose stools, bloating or gas). This is more typical with the oil form rather than the powder.
Drink with adequate water throughout the day. Keep out of reach of young children. Store in a cool, dry place.
If you are pregnant, breastfeeding, taking prescription medication, have a pre-existing medical condition (including any digestive condition, gallbladder condition, or liver condition), please consult a qualified healthcare practitioner before introducing significant changes to your dietary fat intake.
