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.

5.0 out of 5 stars Great for mental clarity
Reviewed in the United States on December 18, 2023
Size: 16 Ounces (Pack of 1)Verified Purchase
I put this in my morning coffee. No taste. It sits at the top though, does not mix well with the coffee. Coffee is mostly in water and some of the extracted oil (not much). Water and oil don’t mix, so don’t expect it to emulsify in your coffee. I won’t knock off any stars for that, because that is expected. Warning though! I was new to C8 MCT oil. One morning I took it straight, and I ended up with terrible abdominal pain, nausea and had to use the bathroom within 30 min. This was user error!! If you ever look it up, which I didn’t before taking it straight, you absorb it too fast and your body may not be able to handle it. Take it with a drink or with food, and start in small doses. Start with maybe a teaspoon (5 mL) and increase gradually. Still give it 5 stars.

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.
