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 and 10% gamma isomers), with no tocopherols. Annatto-E™ 150 contains 150 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 alpha-tocopherol, may interfere with key therapeutic effects of tocotrienols, so it may be best to dose tocotrienols alone, without tocopherols.
