Need a certificate of compliance for dietary supplements

Hi,

Product detail page have been removed due to “product safety issue”.

Amazon asking us provide this king of document: A certificate of compliance, which is a product label review issued by an external compliance service provider, confirming that the label and Detail Page are compliant with all relevant regulations, are free from any unauthorized claims, accompanied by images of the product that have been reviewed

Anyone could recommend a third party company who could prepare this kind of documentation?
