Hello, Alan!
As always, it is so nice to hear from you! We agree- it would absolutely be a great benefit to include more recent researched (with cited sources) and we do have such a document underway! Please check back with us periodically as we hope to publish here soon! No doubt, we hope to set the bar with the highest standard in humic and fulvic acid/chelated mineral (plant derived) supplements! Beyond excited to have you on board!
