Ingredients
Tocotrienols are naturally occurring forms of vitamin E belonging to the vitamin E family. The four main tocotrienols are alpha-tocotrienol, beta-tocotrienol, gamma-tocotrienol, and delta-tocotrienol. They are found in plant sources such as palm fruit, rice bran, annatto, and certain cereal grains. The source, tocotrienol profile, concentration, and additional ingredients vary by supplement.
Tocotrienols are a group of compounds in the vitamin E family. Vitamin E includes both tocopherols and tocotrienols, with each group containing alpha, beta, gamma, and delta forms.
Tocotrienols have a chemical structure similar to tocopherols but contain an unsaturated side chain with three double bonds. They occur naturally in several plant-based foods and oils, including palm oil, rice bran, annatto, and certain grains.
Tocotrienol supplements are commonly provided as standalone vitamin E formulations or combined with tocopherols and other nutritional ingredients. Products may be standardized to specific tocotrienols, such as gamma- or delta-tocotrienol, or may provide a broader tocotrienol complex.
Tocotrienols have been studied for their antioxidant properties, lipid metabolism, cellular health, and other biological activities. However, research findings vary depending on the tocotrienol form, source, dosage, and study population. Consumers should check the product label for the exact tocotrienol forms and amounts.
