Reviewing InstaMix: Bulletproof Coffee on the Go?

by Wesley S

There’s no denying the influence Bulletproof Coffee has had on bringing nootropics to the mainstream. Bulletproof Coffee consumption here at BrainWiz is nearly unanimous, and we are always looking at ways to make the regimen more portable.  The blend of “mold free” coffee, grass-fed butter, and medium-chain triglycerides is (for many of us, but not all) an effective brain energy booster on its own.

Bulletproof recently released their popular Brain Octane Oil in a softgel form, and while some of our testers liked the product, most felt like it did not deliver enough caprylic acid triglyceride bang, for the buck.

Still looking for an easier way to take Bulletproof Coffee on the road, our testers were excited about the company’s new product: InstaMix, a powdered blend of MCT and grass-fed butter, which  is meant to be mixed in with fresh-brewed coffee. Read on to see if  this powder ended up being better than the softgels, and whether or not this is the answer to taking Bulletproof Coffee on the road.

The Ingredients

Per packet: Caprylic Acid Triglycerides (Brain Octane Oil), Grass-fed Butter, Highly Branched Cyclic Dextrin, Oleic Fatty Acid (from Olive Oil)

Caprylic Acid Triglycerides (Brain Octane Oil)

Medium-chain triglycerides, normally in the form of refined coconut oils, have become popular in recent years, largely thanks to the work of Bulletproof founder Dave Asprey.

They’re a primary ingredient in Bulletproof Coffee, and Bulletproof/Upgraded self claims they provide sustained energy to the brain without the crash of stimulants. Research indicates MCT oil creates more ketone bodies when metabolized than most other fats, and these ketone bodies may be quickly utilized by the brain for energy. Their consumption in place of other calories sources has also been linked to increased fat loss.

Regular coconut oil contains only about 8% caprylic acid, so Bulletproof’s Brain Octane Oil is a highly refined derivative of coconut oil targeted toward brain function. Of course, that’s not to say the other lipid compounds in coconut oil don’t have their own potential benefits. Brain Octane Oil may not be as readily stored as fat within the human body, meaning it’s either metabolized for relatively quick energy or expelled as waste.

Bulletproof also claims slowing the digestion of their Brain Octane Oil carries benefits for gut biome health and microbial balance. However, research on that potential benefit is so far pretty sparse, and we’ve chosen to assess the product’s effects as they pertain to mental performance.

A normal tablespoon of liquid-form Brain Octane Oil contains 15 grams of caprylic acid. One packet of Brain Octane contains about 10 grams, so significantly more than the softgels, but still less than a serving of the original oil.

What Our Testers Say

Bulletproof InstaMix
4.2 / 5 Score
  • Convenient
  • Travel friendly
  • Neutral taste
  • Cons
  • Requires hot coffee
  • May take adjustment
  • Summary
    Bulletproof's InstaMix is the most convenient, travel-friendly method we've seen so far when it comes to fat-infused coffee on the road. It needs to be added to freshly-brewed, hot coffee in order to mix well, so it's not a take-whenever "nootropic" supplement, but it does keep us feeling full with a boost in mental energy.
    Beginner Friendly

    “These are a huge improvement over the softgels. I like that they have a mixture of the MCT, high-quality grass-fed butter, because let’s face it, carrying around a stick of butter is just as impractical as carrying around a bottle of oil. I had great energy with this, and even used it in the afternoon, with great success. ”

    “I liked the softgels, and have reached for them a couple of times when I needed a caffeine-free boost during my day. These are not as practical as the pills, but they are more potent. I liked it  mixed with my caffeine-free tea, and will continue using it. The flavor was nutty, and pretty comforting.”

    “This mix is pretty solid when it comes to helping stave off hunger pangs, and give me a boost of energy. I tried mixing it with my cold brew, and had a disastrously clumpy result. I will stick to mixing it in warm coffee going forward. I have had some stomach issues with the full tablespoon of MCT oil before, but this didn’t bother me at all. ”

    “This is a pretty great alternative for when I don’t have the time to make my Bulletproof coffee at home. I still prefer the “real” stuff, but this  is easy to mix, and it stacks well with my regular nootropic regimen. I will keep a couple of these in my briefcase, and at the office, for emergencies. ”

    BrainWiz Tips

    • When it comes to MCT oil, the manufacturer suggests starting with 1 teaspoon of oil to coffee, and gradually increasing until you reach 1 to 2 tablespoons per cup of coffee. Some people experience an upset stomach when first trying MCT oil, and InstaMix is no different. BrainWiz testers have been drinking Bulletproof coffee and/or tea for years, so take your time working up to the full packet, if this is your first experience with MCT oil.
    • Most of our testers relied on their “regular” Bulletproof coffee in the morning, consumed an InstaMix beverage with lunch, which helped them fight afternoon hunger pangs, and slump.


    While not as portable as the Brain Octane Softgels, InstaMix is a (surprisingly great) alternative for those looking for the BulletProof Coffee experience on the go. These packets are TSA-approved, and easy to take along in a carry-on, making it the perfect addition to a road-warrior’s nootropic chest.

    The fact that these packets are also caffeine and stimulant-free makes them even more universally appealing.
