Annatto-E 150 is a unique tocopherol-free, tocotrienols-only product featuring tocotrienols sourced from the annatto tree. Annatto is the richest known source of tocotrienols, containing 100% tocotrienols (90% delta-isomers and 10% gamma-isomers), with no tocopherols.<br><br>Annatto-E 150 contains 150 mg per softgel of delta- and gamma-tocotrienols. Commercial vitamin E supplements are typically rich in tocopherols and low or absent in tocotrienols; however, tocotrienol fractions have unique beneficial effects across a variety of tissues that make them desirable for supporting many aspects of health. Research indicates that tocopherols - especially alpha-tocopherols - may interfere with key clinical effects of tocotrienols, so it may be best to take tocotrienols alone, without tocopherols.
