WHAT IS LJ100® EURYCOMA LONGIFOLIA ROOT EXTRACT?

Eurycoma longifolia grows in rainforests throughout Southeast Asian. Its common name is Tongkat Ali (translates as Ali’s walking stick), which refers to its use as a tonic for male virility. It’s sometimes called “Malaysian ginseng,” because similar to ginseng, it’s regarded as an adaptogen that supports resistance to and recovery from stress of all types. The roots are used for many purposes that fit within the adaptogen category including supporting mood, overcoming fatigue, enhancing exercise, and promoting vigor with aging. E. longifolia can also be considered as an immune adaptogen, enhancing overall immunological vigor of the adaptive immune system. E. longifolia contains several bioactive compounds including quassinoids (e.g., eurycolactone, eurycomalactone, eurycomanol, eurycomanone, and eurycomaoside), alkaloids, flavonoids, triterpenes, and glycoproteins[1,2]

LJ100® EURYCOMA LONGIFOLIA ROOT EXTRACT DOSING PRINCIPLES AND RATIONALE

Because Eurycoma longifolia is an adaptogen, we consider dosing to follow hormetic principles (see Neurohacker Dosing Principles). Herbal adaptogens tend to have a hormetic zone (or range) where there’s a favorable biological response. It’s important to be in this zone. In human studies, LJ100®, a standardized Eurycoma longifolia root extract, has been given in doses ranging from 50 to 400 mg—the most common doses have been 100-200mg. Our dosage of LJ100® will be within the most commonly studied dosage range and is consistent with the dose recommended by the supplier.
