Tocotrienols are members of the vitamin E family. Like vitamin E, tocotrienols are potent antioxidants against lipid peroxidation (the damaging of fats by oxidation).1 2
Where are they found?
Tocotrienols are found primarily in the oil fraction of rice bran, palm fruit, barley, and wheat germ. Supplemental sources of tocotrienols are derived from rice bran oil and palm oil distillates. Tocotrienol supplements are available in capsules and tablets.
Tocotrienols have been used in connection with the following conditions (refer to the individual health concern for complete information):
| Science Rating | Health Concerns |
|---|---|
 | Atherosclerosis |
 | High Cholesterol |
 | Stroke |
| Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit. | |
How much is usually taken?
The typical recommendation is 140 to 360 mg per day. Most studies have used 200 mg daily.
Are there any side effects or interactions?
No significant adverse effects have been reported with tocotrienols.3
Are there any drug interactions?
Certain medicines may interact with tocotrienols. Refer to drug interactions for a list of those medicines.
