My absolute favorite MCT oil! I won’t start my day without it!
Size: 32 Ounce
I have repurchased this Bulletproof MCT oil many times because I won’t start my day without it! I take 2 tsp (max dosage is 1TBSP) in my morning coffee and it helps me feel more focused and energized than just plain coffee. I don’t take Bulletproof MCT oil just for keto effects, but I also notice a positive effect on my brain! I can always tell when I’ve had coffee without it! There’s really no smell or taste and using a small whisk it blends well into my coffee. I’ve also used it in protein shakes and I like it that way too. I’ve had no stomach upset or issues. I think you need to figure out the dose that works best for you and gradually increase as tolerated. It’s very easy to use, super high quality and a great value for the price! I always buy the largest bottle as it is the most cost-effective. The expiration date is about 3 years out so this product stays fresh a long time. I also like that it’s got a safety seal. Overall it’s my favorite MCT oil and I would recommend. ... show more

Been using this for years.
Size: 32 Ounce
Fantastic Product. Blend it into my coffee and mocha with a bit of ghee everyday. Goated product. Steady Energy, a little expensive but worth it.

Brain Went From Dial-Up to Fiber Optic
Size: 16.00 Fl Oz (Pack of 1)
**TL;DR:** This stuff is wonderful. Wakes up the brain, clears the fog, and, wild thought, words actually come out of my mouth in the correct order. Energy is real, not jittery. I tried Bulletproof Coconut Brain Octane C8 MCT Oil, and my brain basically did a hard reboot and loaded the premium DLC. Within minutes, I went from “uhhh… what was I saying?” to finishing sentences like a functioning adult. Sometimes that’s unusual for me, now it’s Tuesday. **What I noticed:** * **Fog? Evicted.** My thoughts stopped moving through molasses and started using the express lane. * **Words appear on time.** Not two exits late, not hiding behind “umm.” Actual words, on demand. * **Energy that behaves.** No caffeine jitters, just a clean, steady “let’s get it done” vibe. **How I use it:** One small splash in coffee or a smoothie. Start modest unless you enjoy learning the *limits* of enthusiasm. It’s flavor-light, plays nice with everything, and doesn’t hijack your drink. **Pros:** * Instant mental wake-up without the chaos * Smooth, focused energy * Pairs with coffee like a power couple **Cons:** * You’ll start judging your old brain fog like it’s last year’s software update * Bottle disappears faster than you planned because you keep using it **Verdict:** If your brain’s been idling in neutral, Brain Octane is the nudge into drive. Wonderful stuff. Clears the fog, words cooperate, energy shows up ready to work. Consider me converted, and coherent. ... show more

Frustration: Great Oil... Poor Packaging
Size: 3 Fl Oz
I started using Bullet MCT oil on August 2025, and I like the taste—it's smooth and not greasy. I’m hopeful it works well for me. However, I’ve noticed a concern: no matter how I position the bottle, whether pouring into a spoon or a cup, the oil tends to leak down the sides of the bottle, making a mess on the table or floor. After reading through Amazon reviews, I learned that the twist cap bottle, which I have, is the cause of this issue. Thankfully, the new bottles now feature a flip cap. I’m glad I bought the 3oz size because, for every tablespoon or two I use daily, a significant amount ends up wasted on the table. ... show more

Been taking it daily for a month. Feel like I have more energy throughout the course of the day... Seems like a good product!

Easily blends with any kind of drink only with battery operated coffee stirrer
Size: 32 Ounce
Blending a small amount into morning coffee or a smoothie gives a gentle pick-me-up that lasts through much of the morning rather than a quick spike. On days when I skip breakfast this oil helps keep me alert and I often don’t feel the mid-morning slump or urge to snack. I noticed that my focus felt sharper about half an hour after my first use and that I stayed energized during work until lunch. I started with a small amount and increased gradually and did not experience any digestive discomfort. Over a month of regular use I found it easier to manage cravings and I appreciated that it mixes seamlessly into drinks without affecting taste or texture. For a clean, simple supplement it has become a useful part of my routine. ... show more
