What is MCT OIL?

Boost Your Mental Power With ‘Brain Fuel’

If you have ever suffered from mental fogginess, forgetfulness, struggling to learn, lack of mental energy, and clarity... then this will be the most exciting news for you: The human brain is made up of 60% of fat, and it needs a constant supply of energy — especially from blood glucose.

However, when you are on the ketogenic lifestyle, your blood glucose is low. This is when your brain will use ketones as an alternative source of energy. The best part is that ketones are a MUCH better source of energy for the brain. They give you better mental focus & clarity.

This is where Kiss My Keto MCT C8 Brain Fuel comes in.

C8 (Caprylic Acid), aka “brain fuel” is 100% extracted from coconuts. It is a natural source of efficient energy for your brain & body — especially in comparison to glucose. It is also considered as a ‘superfood’ among ketoers. That’s because the MCT (Medium-Chain Triglyceride) has a shorter carbon chain, compared to other forms of fatty acids...

… which makes it easier for your body to digest & convert into ketones.

If the nature of your work requires mental clarity & focus to perform better, then this is for you.

Questions and Answers

How quickly do you feel the effects?

You should start feeling the effects within 20 minutes of consuming. If you practice intermittent fasting and you consume MCT on an empty stomach you will feel it even quicker.

How do you take it?

You can take it on it's own with a spoon, pour it into your favorite beverage such as coffee or tea or drizzle it over your salad.

When is the best time to take it?

We recommend in the morning for a quick energy boost or as a meal replacement to suppress your appetite to get you through the day

Are their any side effects?

Too much MCT can lead to an upset stomach, but it quickly passes. That's why we recommend starting slow if you're just starting out, with a teaspoon and then increasing to a tablespoon. We don't recommend more than 2 tablespoons per serving

What is the maximum daily dose?

We don't recommend more than 3 servings per day.

Can I use it if i'm not on a keto or low carb diet? What if I'm diabetic, on the paleo or atkins diet?

Sure, all of our products contain no sugar, low carbs (and in most cases no carbs) and no artificial ingredients. So if you are on keto, paleo, atkins, diabetic or a low carb eater, or if you are just starting out on keto, our products are suitable for you.

Is this product vegan, non-gmo, kosher, gluten free and made in the USA?


Are there any carbs, sugars, caffeine or other stimulants?

No, our MCT oil is pure saturated fat, the best type of fat to burn for energy

What is the shelf life? Do you refrigerate after opening?

It is best to consume within 18 months of opening. There is no need to store it in a fridge

How many calories are in a serving? How many servings are in a bottle?

There is 130 calories in a full serving and 63 servings in a bottle.

How is it packaged? In plastic or glass?

Our MCT Oil is packaged in glass.

What is the MCT ratio of C6, C8, C10 and C12? Is it food grade?

Our C8 MCT Oil Brain Fuel is food grade and is 99% pure C8 Caprylic Acid. It does not contain any C6, C10 or C12 chains. We believe that your body converts C8 and C10 chains to energy much quicker than other chains.

What is the difference between your MCT Oil C8 Brain Buel and your MCT Oil Blend?

Our Brain Fuel is 99% pure C8 Caprylic acid. Our MCT Oil Blend is 60% C8 and 40% C10. C8 is considered the most desirable coconut chain because your body converts it from fat to energy the quickest. Both C8 and C10 chains are great on keto!

Can I cook bake, fry with it?

MCT Oil has a low smoke point so we don't recommend frying it (use coconut oil instead). You can bake with it.

Does MCT have any man-made or harsh chemicals in it? Is it sustainably sourced?

Our MCT oil is derived from sustainably sourced coconuts. There are no chemicals or solvents involved in the fractioning or processing of our MCT oil.
