why does MCT oil cause stomach discomfort?

Answered on August 19, 2014
Created September 20, 2012 at 7:16 PM

so it's fairly well known that MCT oil can cause nausea/stomach cramping for people just starting out taking it.

but WHY would this be? what mechanism is causing this side effect?

Wikipedia says that MCTs basically diffuse into the bloodstream. can anyone elaborate on the process of metabolism for MCTs?

I feel like the pain it causes me (currently unable to consume even half a tablespoon without feeling sick) could mean I shouldn't be consuming it.

But apparently one's body gets used to it after a while

EDITED TO ADD: could the discomfort be abdominal blood vessels opening up to accompany a high influx of MCTs? could the body be confused as to how to digest/absorb the MCTs?

That's called stretorrhea. It happens if you consume too much fat, too fast and don't have enough bile to process it. Also known as disaster pants.

Coconut is natural and much better in my opinion, although even too much of that can give you a stomach upset.

Why are you supplementing with it? Could you do just coconut oil instead? Don't know if that would give you the same trouble...

It seems correct about the bile salts, from the research I gathered it probably has something to do with MCT having an accerlerated effect on gastric emptying. I'll link to the study below.

I didn't adjust to it. If I take it, I get diarrhea, even if I keep taking it. Unless the adjusting takes more than a week. I think it must be impurities in it that cause digestive discomfort. That stuff works hella good though :D.

I know tha it takes adjustment. I want to know WHY. apparently MCTs don't require bile salts, so I don't think that is the cause of the discomfort.

MCTs do require lipase for breakdown. It takes your body some time to unregulated lipase production to deal with higher fat intake.

I also had some bouts with explosive bowel syndrome for the first month or so after upping my fat intake but,now, after a few months I can take in 3 tbsp of MCT oil and 4 tbsp butter in morning coffee with no discomfort at all.

It takes some adjusting too. Ease into consumption of the MCT (1 tbsp a day up to 3 tbsp a day). Be careful! If you attempt too much, bile salts won't be produced fast enough and your body will attempt "purge" itself. It makes for an unpleasant evening.

Reduce the amount until you are used it it and use it as a additive, like add it to your soup or on your veggies AFTER cooking or mix it with butter to add flavor. MCT oil is more effective if also mixed with coconut oil for a sustained release.

I learned about this the hard way. I have eaten coconut oil without problems for years. After a hard trail run last week I decided to try some MCT oil (straight up) so that I could make the drive home without being hungry. It worked. But after I got home I had some broth, an egg and some tomato slices... Within 15 minutes I was violently ill. (This was about 45 minutes after the MCT oil.) The word "purge" used above applies to what happened next. My body got rid of everything in the GI tract in every way it can, all at once. Absolutely disgusting, and I also became incredibly dizzy and was afraid I might faint. Very frightening. I did not know at the time why it was happening. Be careful, my friends!

@PhysiqueRescue a quick Wiki shows bile salts are not used to process MCTs, so why would cramping happen with MCT?

Here is the paper: Research on MCT The two pertinent references for your question are 4, and 33.

are you taking it alone or with food? that will affect the metabolism of it to some degree. I would recommend taking as part of a meal and starting with a small amount like 1 tsp or less and eventually working up to 1 Tbsp. I usually put it on a salad or into a smoothie. If it consistently bothers you (more than 3 or so tries) in any amount I wouldnt continue taking it
