This week I'd like to share my thoughts on an exciting keto product called Coffee Booster which you may have spotted amongst the prizes in my 90-Day KetoDiet Challenge (winners will be announced this week!).

What is Coffee Booster?

Coffee Booster is a fat-based supplement that can be blended with any hot drinks, typically coffee or tea. Just blend it or shake it into a hot drink and you are good to go. And don't worry, it won't taste greasy.

Why Add Fat to Hot Drinks?

When following a low-carb diet, adding healthy fats to your coffee or tea can help you increase and maintain your energy levels throughout the day. Try it for breakfast instead of a regular meal and it can help reduce hunger cravings. As always, you should keep an eye on your calorie intake and make sure you don't over-consume fat.

Who Is Coffee Booster For?

Whether you make "butter coffee" on a regular basis or you are still thinking of trying it, Coffee Booster is a convenient option and great when travelling.

Coffee Booster contains:

  • Virgin, cold-pressed coconut oil. Coconut oil is naturally high in MCTs which provide a quick energy boost and are great for performance.
  • Grass-fed, clarified butter (ghee). Ghee is great for those who can't tolerate butter.
  • Raw cacao powder. I've always been a fan of mocha and I love the addition of raw cacao powder in my coffee.
  • Lastly, there are no sweeteners. I don't use sweeteners in my coffee and I love the pure taste of Coffee Booster. And if you prefer your coffee sweet, you can always add a healthy low-carb sweetener, such as a few drops of stevia or a teaspoon of Erythritol.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I just made coffee booster last night. I used equal parts coconut oil, Kerry Gold butter and cocoa powder. I melted all together in a pot.  Poured into a glass storage container and flash froze to not allow oils to separate. Pulled out of freezer and put in cabinet at room temperature. Worked perfectly!!  No need to spend the high price when you can make your own.  If you can’t do dairy substitute butter with ghee.


Do you think you could make this yourself? Do you have the list of ingredients and percentages?  Can you stir it in or still need fast blender?


Yes, the ingredients are listed in the post but I don't know the exact blend 😊 You don't need a fast blender - a hand shaker will work just as well.


Looks great but sadly it does not look as if I can get it in the UK-😞


Yes, I think it's US only at the moment.


Easy to make: coconut oil, ghee and raw cacao powder.  Costco in the UK has a very nice organic raw cacoa powder and it's super cheap too!  I just came back from London and brought two bags with me.
