How does iHerb ensure product authenticity and quality for its customers?

iHerb ensures product authenticity and quality primarily through a rigorous quality control process that includes offering well-known national brands with established reputations and internal quality checks. For its own house brands, iHerb employs the iTested program, which involves independent third-party laboratories testing products for ingredient purity, label compliance, and safety. These tests produce iTested Verified Reports (Certificates of Analysis) that are transparently available to customers on the product pages, providing detailed evidence of quality and authenticity.

Additional measures include:

• Selling brands that also appear in other reputable marketplaces or retail stores, ensuring these brands maintain high standards due to their broader market presence.
• Encouraging or requiring suppliers to comply with ethical standards, including certifications related to supply chain integrity and human rights, although iHerb does not currently conduct onsite audits of suppliers.
• Supporting third-party certifications from recognized organizations such as NSF®, USP®, UL®, and ISURA®, which provide further quality guarantees for dietary supplements.

Together, these steps help iHerb maintain a trustworthy product offering by combining brand reputation, independent testing, transparency, and ethical sourcing commitments.
