Simply Seaweed branded Ascophyllum nodosum does not have a VOHC Seal of Approval.
The worldwide Veterinary Oral Health Council (VOHC) has recognised the dental benefits of Ascophyllum nodosum, and we DNA test our seaweed to verify that it is Ascophyllum nodosum. However, as the application process for a VOHC Seal of Acceptance for a brand/product is complicated and costly, this unfortunately is not achievable for us as a small business.
