 The market condition of Oleuropein

  1. Almost all the suppliers in China are unable to produce big quantity. Because the raw material resource (Olive leaf) is quite limited in China.
  2. The Oleuropein content of each production lot differs largely. Some production lot contains 13% of Oleuropein while another may contain 18%.
  3. Most of the suppliers here in China cheat for their Olive leaf extract assay. They mark higher no. on the package or in their COA. In fact the Oleuropein content is less than the no. they marked. For example, they mark their Oleuropein content as 25% while in fact it only has 19%.
