Hi Wasabi,

Thank you very much for researching & clarifying this info. I think for now, for financial reasons, we will stick with the DW, as it is quite inexpensive compared to the alternatives: $15 for 2.5 pounds -- by my reckoning, about $ 0.33 per serving based on the recommended 15 gram serving.

Keep up the good work. I hope your olive leaf extract experiment is helpful.
