Medium-chain triglycerides are fats that come from coconut oil, palm oil, and butter. They have been used to manage body weight and improve mental function. Medium-chain triglycerides can be taken as an oil, pill, or powder. They can also be injected into the bloodstream by a healthcare provider.
There are no advised doses for medium-chain triglycerides.
What Research Shows
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It is likely safe to take medium-chain triglycerides in small doses for a short time, but stomach upset may happen. Not enough studies have been done to say whether they are safe to take for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
