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.
