About this ingredient
Ingredients
Tocotrienols are naturally occurring members of the vitamin E family. The four main forms are alpha-, beta-, gamma-, and delta-tocotrienol. They have a chromanol ring and an unsaturated phytyl side chain, distinguishing them structurally from tocopherols. Tocotrienols occur in foods and plant oils such as rice bran, palm fruit, annatto, and certain grains. The exact tocotrienol profile and concentration vary by source and supplement.
Tocotrienols are a group of vitamin E compounds that occur naturally alongside tocopherols in various plant foods and oils. The tocotrienol family consists of alpha-, beta-, gamma-, and delta-tocotrienol.
Tocotrienols are structurally related to tocopherols but have an unsaturated side chain, giving them distinct chemical characteristics. Different plant sources can contain different proportions of tocotrienol forms. Annatto, for example, is particularly rich in delta- and gamma-tocotrienol, while rice bran and palm-derived ingredients can contain mixtures of tocopherols and tocotrienols.
Vitamin E compounds are recognized for their antioxidant activity and their role in protecting cells from oxidative damage. Tocotrienols have also been studied in areas including lipid metabolism and cardiovascular and neurological nutrition, but research findings depend on the specific tocotrienol form, dose, and health outcome.
Tocotrienol supplements may be available as softgels, capsules, powders, or mixed vitamin E formulations. Consumers should check the product label for the specific tocotrienol forms, total amount, source, serving size, and whether tocopherols are also included.
