What We Couldn't Verify
- On-site facility inspection was not conducted
- Certification claims (SQF, Kosher, USDA Organic) are self-reported from the company website and were not independently confirmed via an issuing-body registry
- Supplement/nutraceutical service is implied through masking and functional-flavor capability rather than explicitly marketed as a dedicated dietary-supplement line
