My absolute favorite MCT oil! I won’t start my day without it!
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.

Frustration: Great Oil... Poor Packaging
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.

Easily blends with any kind of drink only with battery operated coffee stirrer
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.
