Primal C8 MCT Oil 1L

Primal Collective™ Clean 100% C8 MCT Oil. Odourless. Tasteless.

1000ml. 66 x 15ml servings. Our MCT Oil is a single medium chain fatty acid extracted only from coconut oil. No Palm Oil. No added ingredients whatsoever. A dose of 1 to 2 tablespoons is commonly used together with coffee, cacao or shakes for breakfast to support intermittent fasting,

Ingredients: 100% Caprylic Acid MCTs in a BPS, BPF and BPA free bottle.
Because MCTs are solvents, they can also leach material/plasticizers from their storage containers (e.g., phthalates) which can cause issues (endocrine disruptors) over time. This is why we have diligently selected a bottle that is not only BPA free, but also free of the substitutes (analogues) of bisphenol-A: BPS and BPF free.

Also available:  C8 MCT Powder

Fatty acid profiles of virgin coconut oil. | Download Table

Coconut oil is made up of only 13% C8 and about 50% C12 (Lauric Acid) which is not an MCT.  It is a long chain fatty acid (LCT). Comparing MCTS to LCTS. MCTs are more effective for:

  • Metabolism: MCTs metabolise faster, enhancing protein metabolism and energy expenditure​​​​.
  • Weight Loss: MCTs lead to greater weight loss and reduced body fat compared to LCTs​​.
  • Energy Utilisation: MCTs increase thermogenesis more than LCTs.
  • Blood Lipids: MCTs improve serum lipid profiles without adversely affecting lipid levels​​​​.
  • Protein Sparing: MCTs in nutrition improve nitrogen retention and protein sparing​​​​.
  • Glucose Metabolism: MCTs positively affect insulin sensitivity and glucose metabolism​​.
  • Fat Oxidation: MCT ingestion enhances postprandial (post meal) fat degradation and increases fat oxidation​​.
  • Satiety: MCTs can provide a feeling of fullness, reducing appetite and cravings.

Beautiful clean product

Light, clear and flavourless product that is perfect to put in our morning coffee. Don’t even know it’s in there!

Primal C8 MCT OIL

Love this product. I use it in my morning bulletproof coffee and again in the evening with my bedtime caffeine free latte. I notice a huge difference with my vestibular migraines when I miss taking it.

Diane Dewing (Perth, AU)

This product is amazing. A psychiatrist put me on to it to help with ADHD symptoms. It helps brain fog and allows me to be more focussed. I add it to my first morning coffee, also adding cream with 65% fat, and this makes it a bulletproof coffee which takes me to lunch time and beyond. I love this product. I'll never stop using it. Primal make great products

DF (Sydney, AU)
Easy opening and no leaking

I bought Primal MCT oil for the first time. Usually I buy Bulletproof brand. It has an easy opening, no leaking and at the same time see through bottle and price is more attractive
