What the label says

A typical 200:1 label is filled in.

:1
Eurycomanone a day

  • Daily dose

  • Eurycomanone

  • Standardization

  • Extraction

Compared with the human studies: 50 to 400mg a day of a water extract of root, standardized to .8 to 1.5% eurycomanone. Most used 200mg. This compares the label only. It cannot test what is in the product.

The benchmark

The research behind the comparison

  • 50 to 400mg a dayThe daily doses of extract used in human studies, most often 200mg.
  • .8 to 1.5% eurycomanoneThe strength of the extracts studied, set by the Malaysian Standard MS 2409:2011.
  • Water extract of rootThe extraction method used in the studies.
  • 1.6 to 3mg eurycomanoneWhat the most studied dose, 200mg a day of a standardized extract, delivers.
