MCTs are well tolerated with no serious demonstrable side effects.
Ingestion of larger amounts (>25–30 g) of MCTs causes
adverse gastrointestinal symptoms, including nausea, vomiting,
abdominal cramps, gastrointestinal discomfort, bloating, and
osmotic diarrhoea (Jeukendrup and Aldred, 2004). Due to
hyperosmolarity, MCTs cause a large influx of fluid into the
large intestines and initiate gastrointestinal problems (Bainbridge
et al., 1999) and so it is generally advised to start MCTs
treatment gradually and to increase the amount over time.
