This is one of the most interesting posts that I have found in so far as MCT oil and heart palpitations are concerned; thank you. I recently started taking one teaspoon full of MCT oil with my coffee. (I drink two cups per day but only took the MCT oil with the first cup of the day). I noticed that I was suddenly overall weaker on my rowing machine and, when out running, a distinctively weaker feeling came across my upper chest. When lying down and preparing for sleep, I was aware that my heart was irregular and, for no apparent reason, feelings of anxiety built within me. This all came to a crescendo last week while I was driving on the motorway. My heart was accelerating and my forearms became so weak that I could barely grip the steering wheel. I was feeling feint, too. I managed to get my car over onto a Lay-by where I rested until I felt confident enough to drive to a nearby Accident and Emergency centre. After a day of tests which include two ECGâs and three blood tests I was discharged, but the Consultant was unable to diagnose precisely what had caused my symptoms. Since returning from hospital I neglected to include MCT oil in my coffee and have been feeling absolutely fineâŚuntil today, that is. Having taking a teaspoon full this morning I am feeling absolutely jittery, my heart is all over the place - so to speak - and even though I am usually very calm and relaxed, I am feeling anxious. Needless to say I have just poured ÂŁ18.00âs worth of MCT oil down the drain and will return to good old butter to fortify my morning coffee!! Thanks again to Robinette71 for the initial post - it has been invaluable to me!!
MCT oil almost killed me
Wow Raindown, lucky you found out the problem. Interesting how using food instead of the supplements has worked out better. Iâm a fan of butter!
And Welcome to the forums!
I got a ârushâ from MCT oil, but is was not in energy.
One time I thought I would try some pre-run to see if it gave me more energy for the workout. I had to return home after the first 100 yards.
I have the same issue, coming from Europe, MCT oil causes me heart arythmia, which is very scary. When I stopped MCT no more arrhythmias. But my heart rate remains elevated by about 10-15bpm always, at rest or exercising
Wow even now I never actually connected the MCT to what I got diagnosed as âpanic attacksâ while driving, I got the exact same reaction as Raindown above⌠it went away with time and some pills to help me calm down a bit. But I was having it when I went to bed too at times, feeling my heard racing and waking up with a jolt feeling like I was sure my heart was about to stop⌠very unsettling. Havenât had any of these symptoms for a while now, and guess what, I also havenât had any MCTâŚ
Started taking some again lately as I got back on the Keto diet after a period of regular eating, and realizing that I just wasnât feeling good and wanted to get back on the train, so to speak.
I donât use much, maybe a teaspoon and only once every other day or so, but seeing this thread was such an illuminating moment, and I will either get rid of all of it now, or maybe in a week or so, try a very low dose and see how that goes, as I know in the beginning I felt really good on it. It kind of warmed up my core it felt like, in a good way⌠but maybe that was just the effect of the Keto diet kicking in, I donât really know for sure.
Thanks for sharing this, have a good one and take care people. 
Really not a good idea, as I hope youâve realised.
Itâs not necessary at all.
How long did it take for the heart palpitations to go away? When I started feeling a little off and having heart palpitations the past week I traced it to the possibility of me ingesting MCT oil in my smoothies the week prior along with a generous amount of coconut oil with a dessert I had made last week. My blood pressure and heart palpitations weâre pretty severe yesterday so I had to go to the ER. Any advice on how to get rid of the heart palpitations would be greatly appreciated.
If youâve stopped taking the MCT & coconut oil and are still getting issues then they cannot be the cause.
I feel safer just getting what I need from foods, glad I read this because Iâve been tempted to use extra things like MCT, BCAA (I think I have that last one right initials). I stick with the best meats, vegies (cruciferous, low-carb) and still have a little dairy. I didnât find a huge change supplementing with B vitamins and others, so I quit all of them except Magnesium. I feel that it has helped me so I stick with it. Maybe I need more vitamins and minerals but for now, I have no issues with digestion, or headaches are rare and I feel strong most days at 69.
Iâm not saying I wouldnât add something if I truly felt I needed it though, I donât think I will be needing MCT oil but I would like to know how all turns out after dropping it @Robinette71. So glad you are doing better already.
