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 of delta/gamma tocotrienols per softgel. Commercial vitamin E supplements are typically rich in tocopherols and low in or devoid of 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 the key therapeutic effects of tocotrienols, so it may be best to dose tocotrienols alone, without tocopherols.
