Great product but bad shipping
I was able to get a refund thru Amazon but not the vendor the way it was set up. The package was soaked in oil and when I opened it up, the protective seal was completely off. This is my 2nd bottle but first bad shipping experience. The product itself is great. Start with a tsp with coffee. If you start with too much it can give you a stomach ache.

I purchased the product to assist with Keto; however, the benefits of using this product exceeded my expectations. I am noticing that I have more clarity in my thoughts- I am not searching for words as much or brain fog. I started noticing this after about 4 weeks. It is tasteless and the consistency doesn't bother me at all. I do have a problem that because it is oil, you don't get the full tablespoon. I have not mixed it with coffee. I was drinking it with my tea, but I wanted to see if it would make a difference if I consumed it in cold mixes, and I don't see the difference. Did not irritate stomach or make me feel off. Great product.

I must say- I loveeee this product and I'm so happy I gave it a try. Bulletproof Brain Octane has been a total game-changer for me. I’ve been incorporating it into my daily routine for a few months now, and the difference in my mental clarity, energy levels, and overall well-being is nothing short of remarkable plus I’ve notice it’s help me lose weight on a daily basis. I feel the difference when I don’t take it. This MCT oil is incredibly pure and potent, making it a powerhouse of energy for the brain and body. From the first week, I noticed a significant uplift in my focus and productivity. My mornings start with a Smoothie and two spoons and that’s all I need for the rest of the day.

Size: 16 Ounces (Pack of 1)Verified Purchase
This is a Keto lover's dream! I have used different brands of MCT oil to meet my ketogenic diet lifestyle requirements. This is the one brand of MCT oil I would recommend to anyone who follows a ketogenic diet, a high fat low carb diet, an intermittent fasting lifestyle, or anyone who simply likes to use MCT oil for any reason. One of the main reasons you should use this product is because it contains super high quality MCT's (medium chain triglycerides) that are easily broken down by your body and almost instantly converted to energy; trust me, you will feel the difference!

If you are someone who likes to make bulletproof coffee, this is the product for you! It has a little to no taste, it has a very clean feel when consumed, and it will give you the burst of energy most people use MCT oils for. The Bulletproof Brain Octane Oil is beneficial to use when making bulletproof coffee because it also fights cravings and keeps you feeling satisfied. Since a ketogenic diet and intermittent fasting go hand in hand for many people, this is a product that will help you from fighting with hunger during the fasting period. I use it every morning in my bulletproof coffee because it will boost your ketone levels while keeping you in a fasted state since it is purely fat!

The Bulletproof Brain Octane Oil can also be used for cooking. However, it is recommended that you only cook with low temperatures when using Brain Octane Oil which could be a slight negative, though I would not see why anyone would need to be cooking with high temperatures with MCT oil. A huge positive about cooking with the Brain Octane Oil is that there is no taste, so it will not change the taste of the food you love! Since there is no taste, another positive note is that the Brain Octane Oil can be added to your foods to incorporate more fat into your diet without changing the taste. You can add it to salads, mix it in smoothies, or simply pour it over any food you like. It is a great way to keep your body running smoothly in a ketogenic or fasted state! The Brain Octane Oil is very convenient because you only need a tablespoon to get an extra 14 grams of high quality fat into your diet.

The one reale negative I would note about the product is that it can be a little bit messy because it is hard to clean up and leaves an oily residue if it is spilled. However, this seems to be more of a bottle design negative than the actual MCT oil itself. I have found that poking a small hole in the top of the safety seal is a good way to keep the oil from spilling or leaking out of the bottle when you are pouring it. This is an easy fix that makes the product close to perfection, in my opinion.

Overall, I would highly recommend this product if you are looking to get a good boost of energy, a clean feel, high quality MCT's, and keeping yourself in ketosis and feeling sharp!
