Estroven’s Commitment to Quality

We are proud of our products and how well they work. Every Estroven production run undergoes a great deal of testing for purity and potency. These tests are performed by qualified laboratories, which follow standards set by various scientific agencies, including the Food and Drug Administration (FDA), U.S. Pharmacopeia (USP), NSF, AOAC, and other internationally recognized standard-setting authorities.

Vendor Selection

We have developed a strict set of standards for the vendors who supply our ingredients and products. All suppliers must follow current Good Manufacturing Practices (cGMPs). We audit all facilities and operations to be sure they meet current good manufacturing standards. We constantly exchange information with our vendors, so that we can keep improving on our process.

Testing Process

All batches of our products pass through a thorough validated analysis before they are distributed to stores. Qualified analytical testing laboratories test for potency so that our products can be correctly labeled. Proprietary blends of herbs cannot be tested by traditional methods; therefore product specification standards are used. We have standard operating procedures for:

  • Product acceptance
  • Reviewing and releasing product for distribution
  • Testing
  • Analysis
  • Packaging
  • Cleanliness of quality assurance areas, storage, and distribution
  • Complaints
  • Reserve areas for retaining samples and records (including finished goods and raw materials)

Stability Testing

It is essential that the quality of our products does not lessen over time, and that they are as effective from the day they leave the plant to the day you purchase them. For this reason, we make sure that they meet expiration date requirements, so whether you use the product the day it is made or at the end of its shelf life, it delivers what we promise. Annual stability testing is a standard process for Estroven.
