Annatto-E™ 300 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 and 10% gamma isomers), with no tocopherols. Annatto-E™ 300 contains 300 mg per softgel of delta/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 alphatocopherol—may interfere with key therapeutic effects of tocotrienols, so it may be best to dose tocotrienols alone, without tocopherols.
