For Dietary Supplementation "I took a tiny sample of MCT oil (Bulletproof) in my coffee yesterday. Took it on an empty stomach. Within 5 minutes of drinking the coffee, I experienced severe cramping, dizziness, a blackout that caused me to pass out on my kitchen floor and hit my head, and vomiting. This was all followed by diarrhea and abdominal cramping that lasted for 6 hours or until I finally took Pepto Bismol. And then I was just left with nausea. I tremendously regret taking the oil before doing well-rounded research. I understand it doesn’t affect everyone the same, but it was a seriously traumatic experience for me, and I hope anyone considering taking it for the first time reads this and takes heed."

For Dietary Supplementation "1/2 tsp first time using it. Within a half hour, I was throwing up, burning up to the point I took my clothes off, laying on the floor, felt like I was dying. Bad stomach pain and diarrhea. Had to take the day off work. Finally felt better a few hours later."

Medium chain triglycerides for Dietary Supplementation "I've been taking MCT for a week now. I started with half a top in water to see if I had a bad reaction. I did get a little bit of diarrhea the first 2 days as well as a little upset stomach, but it all went away by the third day. I've lost 3 lbs. so far. I have also cut my sugar intake, and I stop eating at 6 p.m. After that, I only have tea, coffee, or water. We'll see how it goes after a month or so."

For Dietary Supplementation "Took 4 to 5 drops in a smoothie, and I totally regret it. I'm in horrible pain. My abdomen is killing me, the diarrhea never stops and smells foul. I won't ever use it again. They're not kidding when they say, 'can cause G.I. discomfort.'"

Medium chain triglycerides for Dietary Supplementation "I had one dose in my coffee on Saturday, and it is Tuesday today, and I still have very bad diarrhea and pain in my stomach, and I can see my stomach expanded on one side. Never going to take MCT again."

For Dietary Supplementation "I followed directions on the bottle; 1 tsp in a cup of tea; after fifteen minutes, stomach and bowels started hurting severely; fifteen minutes later I was praying to die! I asked God to let me die or please take the pain away! The pain caused profuse sweating! I thought I was dying! Had vomiting, severe diarrhea that lasted on and off for 12 hours along with severe cramping pain! After 16 hours, the pain was easing up; thought I felt as if I needed to use the bathroom, and when I did, I passed nothing but bright red blood! I knew bright red blood suggests arterial blood and isn’t really serious! After surviving these initial episodes, I lived on a liquid diet for two days and very little solid food for another two days; vibrations from walking caused pain; took over a week to be normal again! I usually read information before starting something new but NEVER dreamed an 'oil' would have such horrendous side effects! Learned my lesson!"

For Dietary Supplementation "I started a keto diet and used the chocolate-flavored powdered oil in my coffee 3 times a day. The only times I've had problems with it was when I cheated and ate junk, then it gave me diarrhea and terrible gas. As long as I ate healthy, I had no problems at all. I've lost 65 lbs and feel great!"

Medium chain triglycerides for Dietary Supplementation "Took the recommended minimum dose of 1 teaspoon, and within 20 minutes, became dreadfully ill. I experienced horrendous stomach pain and started vomiting, very frightening indeed. Eventually, after a few hours, I suffered diarrhea and felt cold and shivery the whole night long. I still felt stomach pains the next day. Definitely would not recommend."
