Bulletproof Brain Octane C8 MCT Oil, 32 oz – 100% Pure Coconut Oil, Triple-Distilled Keto Energy Supplement for Coffee & Smoothies, Unflavored, No Additives or Fillers, Non-GMO

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.

Bulletproof Brain Octane C8 MCT Oil in travel size is perfect for my coffee—mixes smoothly without oily residue and gives steady focus through afternoon slumps. 3oz bottles fit my gym bag for pre-workout boosts, cutting cravings while keeping me energized. Pure C8 quality makes a noticeable difference!

I’ve been using Bulletproof Brain Octane C8 MCT Oil for several years now, and it has become a staple in my routine. I notice the difference every time I use it—it gives me steady energy and mental clarity without any crash. The quality has always been consistent, and it truly works as advertised. I’m very happy with this product and will continue purchasing it.

Great Product! Have used several different MCT oils and feel that Bulletproof seems to be the best of the rest!

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.

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.

**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.

I've tried several different c8 oils and this has been the best one I ve found. I feel I get the best keto weight management with this compared to others I've tried. There is no taste and I appreciate the wholesomeness of the product .
