Ever wonder how your ingredient specifications measure up to regulatory and industry standards?

Supplement and Ingredient Sustainability and Traceability

by NaturPro in Comments: 0

The Ethical Sourcing Review™ is one of the most comprehensive and stringent standards developed to improve sustainability of dietary ingredients from natural sources.

Supplement and Ingredient Sustainability and Traceability

The following outline covers subject matter covered in the 100-part ESR™ Sustainability Questionnaire. ESR™ standards are derived from the International Labour Organization Labour Principles of the United Nations Global Compact, the UN Forum on Sustainability Standards, WHO GAP, NOP Organic, USP <561> and US FDA 21 CFR 111.

Supplier Quality Verification Program (SQVP)

by NaturPro in Comments: 0

NaturPro Scientific has been working to develop a comprehensive Botanical Raw Material Supplier Quality Verification Program (SQVP).  The SQVP program stands on the shoulders of giants, combining the best of many prevailing quality standards.

The SQVP considers a number of questions and issues mentioned by industry in response to recent initiatives to develop universal standards for dietary ingredient raw materials and supplier qualification.  It combines previously developed standards such as Good Agricultural and Collection Practices developed by WHO and AHPA, Good Manufacturing Practices developed by FDA and other countries, and Risk Analysis tools like HACCP used for food and product safety verification. The SQVP Program Toolbox also include checklists and standards already developed for specific regulatory requirements, such as the SIDI workgroup documents used for dietary ingredients.

The SQVP meets the requirements of the Foreign Supplier Verification Program (FSVP) required under the new FSMA law put in place by the US FDA. 

The objective of this program is to apply global and US regulatory and quality requirements to provide a working system for large-scale, global sourcing and quality control of natural products intended to support human health. The SQVP is intended to be applied broadly to different types of supply chains for dietary ingredients, from a small mountain village in China to streamlined, vertically integrated operations in Europe.

The SQVP also attempts to list program components which may not be directly related to audit criteria, but are critical to the operational success of the program.

While the SQVP system is intended to provide a minimum mandatory level covering the areas of highest risk and regulatory focus, it provides a working model for a Sustainability Program which includes ways to recognize practices for raw materials that go above and beyond the minimum requirements, and also include some attributes from previous guidances that are considered lower-risk and are difficult to control.
