Improving the quality of dietary supplements

An agreement between ingredient suppliers and supplement manufacturers, when implemented, should raise the confidence of consumers that the dietary supplement they buy actually contains what is stated on the label.

Called SIDI (Standardized Information on Dietary Ingredients), it includes three information sheets.

  • Product Information Data Sheet
  • Site Quality Overview
  • Supply Chain Security Overview

SIDI is a long awaited step towards developing good manufacturing practices in the dietary supplement industry.
