  • Clean boost of brain fuel without the crash
Size: 16 Ounce
I've tried several MCT oils, but Bulletproof's Brain Octane is one of the cleanest and most effective I’ve used. I take a tablespoon before my morning coffee, and it genuinely helps me feel sharp and sustained without the mid-morning energy dip. This C8 oil blends effortlessly. No weird aftertaste or greasy layer like others I’ve tried. It also hasn’t upset my stomach, which is a common issue with lesser-quality MCTs. I appreciate the emphasis on purity and sourcing. If you're doing keto or just want mental clarity and better focus, this has been a game-changer in my routine. Bonus: it doesn’t solidify easily in cold temps like coconut oil. Pros: Fast, clean energy Blends easily in coffee or smoothies No flavor or odor Tip: Start with 1 tsp and work up to avoid digestive upset. ... show more

  • Cravings are gone!!
Size: 3 Ounce
I bought this as it came recommended for keto. I dont have a wide variety diet so I thought maybe adding this would help get me through the flu stage of keto, and goodness, Im now on my 2nd bottle, my cravings are gone, my mental function is clearer, I feel alert but not wired. Im not over eating anymore, I feel great. I started low and slow and currently use 1 tbsp now. Will add more if need be but so far things are great. The first few days I had rumbley stomach but thats it. No other issues. Love this product and will continue to use. ... show more

  • Very high-quality MCT
Size: 16 Ounce
This stuff really lights up my brain! I’ve just recently started bulletproof and started using this instead of the powdered MCT oil and I can tell you there is a difference and that not all MCT is created the same. I use 1 teaspoon of this along with my grass, fed butter, and my DECAF coffee instead of the regular caffeinated coffee that is recommended but it literally lights up areas of vibrating after drinking it and sustained my hunger and energy for several hours. ... show more

  • Highest quality and most affordable MCT oil!!!!
Size: 16 Ounce
Larger size than what you’d find in store and for a better price too! Can’t complain, happy with my purchase. This product is wonderful to use, the taste is mild and easy to palette and doesn’t really have an odor. I mix it with my coffee.

  • From the '80s Gym to Today's Biohacking: MCT Oil Delivers Consistent Results
Size: 16 Ounce
As someone who's been experimenting with MCT oil since the '80s, I've seen the trends come and go. But one thing remains consistent: the real benefits of quality MCT oil for energy and fat metabolism. Bulletproof's Brain Octane C8 oil is the most refined version I've tried. It's pure caprylic acid (C8), which is the fastest-acting MCT for ketone production. This means quick, clean energy that doesn't spike my blood sugar like carbs. I use it every morning in my coffee, mixed with organic honey, cacao powder, and collagen. It's a delicious ritual that kickstarts my day and fuels my workouts. -What I love about this MCT fuel- **Noticeable energy boost:** I feel a difference within minutes of taking it. It helps me power through my workouts and stay focused throughout the day. **Improved fat burning:** I've noticed a slight decrease in body fat since I started using it consistently. **Easy to digest:** Unlike some MCT oils that can cause stomach upset, this one is gentle and mixes easily into drinks. * **Tasteless and odorless:** It doesn't interfere with the flavor of my coffee or other foods. **Addressing the Negatives:** I've read some negative reviews about Brain Octane, but I believe many issues stem from misuse or unrealistic expectations. Remember, this is a *supplement,* not a magic bullet. Some people complain about digestive issues, but this is easily avoided by starting with a small dose (1/2 tsp) and gradually increasing it. And yes, storing it in the refrigerator will make it solidify, so just keep it at room temperature. If you're looking for a clean, fast-acting energy source to support your workouts and mental clarity, I highly recommend Bulletproof Brain Octane C8 MCT Oil. It's a staple in my routine and has consistently delivered results. ... show more

  • Shop around before purchasing this.
Size: 16 Ounce
I used this for quite a while until I found an alternative brand with the same exact quality, but with more product. I don’t think there is anything special about the brand unless you’re just overly name brand conscious. The quality is good, just not worth the price when other brands provide the same exact product for cheaper. ... show more
