This is valid and something I'm trying to rectify. The information provided is from the label/company. The short term goal is have more detailed information coming for many products/companies. However companies are unsurprisingly reluctant to disclose manufacturing/sourcing information due to either quality concerns or competitor threats. Many companies however are quite transparent and will disclose sources of individual ingredients. I want to get to this level of detail so it is easily accessible to those who want it. I've reached out to many companies who generally do respond - will update the table as new info arrives.
