**About Health Food GMP**
Health Food GMP (Good Manufacturing Practice) is a standard for the manufacturing and development of safe and reliable supplements and health foods. This includes a process of auditing and certifying the factories of health food manufacturing companies based on the "Health Food GMP Guidelines" established by the Ministry of Health, Labor and Welfare.
Certified factories have been confirmed to implement proper manufacturing and quality control practices. Our factory has obtained certification for voluntary health food safety inspections and has received a GMP certificate of conformity from the Japan Health Food and Nutrition Food Association. We manufacture under strict controls, ensuring that seed bacteria are meticulously managed. Additionally, genetic testing confirms that there are no mutations at the DNA level, and we thoroughly check for contaminants at each step of the manufacturing process.
If you prioritize the safety and quality of health foods, we invite you to consider products from our GMP-certified factory.
