Edible oil originating from plants are rich source for tocotrienols. Crude palm oil extracted from the fruits of oil palm (Elaeis guineensis) particularly contains a high amount of tocotrienols (up to 800 mg/kg), mainly consisting of gamma-tocotrienol, alpha-tocotrienol and delta-tocotrienol.

Common sources of tocotrienols are:

Tocotrienols From Normal Diet Alone

Since tocotrienols only occur at very low levels in nature, with the highest concentration found in palm oil, it is virtually impossible to attain the amount of tocotrienols that show beneficial effects from the normal diet alone. For example, one would need to consume a cup of palm olein (cooking oil) a day to get the level required for effectiveness as described in most studies.
