Samples from all suppliers are sent to an independent lab for testing to assure quality and purity standards are met.
Every batch of raw materials we use must have a certificate of analysis.
Every year, InClover experiences regular internal auditing of all our quality control procedures. The current quality systems in place are cGMP, AAFCO, the FDA, HACCP and NASC Independent Audits.
I would feel very comfortable using products from this company!
