iHerb is committed to delivering the highest quality health and wellness products. To guarantee safety and product integrity, we maintain strict operational standards from the moment an item enters our fulfilment centers to the moment it reaches your door.
Here is how we ensure the quality of the products you order:
NSF-Certified Storage Facilities
Proper storage is critical for maintaining the effectiveness of vitamins, supplements, and natural health products. Our global fulfilment centers are NSF Certified, meaning they meet stringent industry standards for public health protection.
Temperature-Controlled: All products are stored in carefully monitored, climate-controlled environments to protect them from extreme heat, humidity, or cold.
Clean Environments: We adhere to rigorous sanitation protocols to promote safety and preserve the integrity of every item on our shelves.
The iTested Certification for iHerb Brands
We hold our exclusive, house-developed iHerb brand products to the highest possible standard through the iTested certification program. Every iHerb brand product undergoes strict evaluation, including:
Independent Lab Testing: We use objective, third-party laboratories to evaluate our products.
Verified Quality and Purity: Products are rigorously tested to ensure they are free from harmful contaminants.
Guaranteed Label Accuracy: We verify that what is printed on the label is exactly what is inside the bottle.
Have specific questions about a product's ingredients?
While iHerb ensures the safe storage and handling of all inventory, individual product formulations are managed by their respective brands.
If you need deeper insight into a specific item, we encourage you to contact the manufacturer directly regarding:
Specific product certifications (e.g., Organic, Non-GMO, Vegan, Kosher)
Detailed manufacturing processes and facility standards
Ingredient sourcing and allergy-related inquiries
Manufacturer contact information can typically be found directly on the iHerb product display page, product's packaging, or on the brand's official website.
