iHerb is a global health-and-wellness ecommerce retailer founded in 1996. The company sells vitamins, supplements, skincare, grocery, sports-nutrition, personal-care and related products to customers in more than 180 countries. One of the most important differences between iHerb and a large open marketplace is that iHerb states that the products in its catalog are sold and shipped by iHerb rather than by third-party marketplace sellers. Its current About page reports more than 50,000 products, more than 60 million customer reviews and 16 million active customers, but those scale figures change over time and should not be treated as permanent facts.
The stable point is that iHerb operates as a direct retailer with a globally distributed fulfillment network and multiple country-specific shipping options. Product quality and suitability still need item-level review. Supplements can differ in dosage, serving size, active ingredients, allergens and formulation, while skincare and food products can have different storage and expiration requirements. iHerb promotes a Quality Promise that includes sourcing from trusted brands and authorized distributors, documentation such as Certificates of Analysis and climate-controlled fulfillment facilities. Those controls can improve supply-chain confidence but do not make every supplement appropriate for every person.
Customers with medical conditions, prescription medicines, pregnancy-related concerns or allergies should use a qualified healthcare professional for individualized advice rather than relying on customer reviews. International orders add another layer because import rules differ by country. A product that is legal and routinely sold in the United States can be restricted, taxed or delayed elsewhere, and customs authorities can impose destination-specific limits. Shipping methods, duties, payment options and delivery estimates should therefore be checked for the actual destination. Returns are also market-sensitive. iHerb’s current policy gives most products a 30-day return window from receipt and gives eligible iHerb-brand products bought directly through iHerb a 90-day window.
Products bought through other platforms generally follow a 30-day window under iHerb’s current table. Refund requests are reviewed individually and are not automatically approved merely because they are submitted. If a physical return is required, the customer can be given a deadline after approval, and international customers do not always receive prepaid labels. Refund timing depends on the payment method and can take longer for international providers. Customers should keep photos of damaged packaging, lot or expiration information and the order record when raising a quality or delivery issue.
Customer support is available through the official Help Center and online service channels, and iHerb publishes official social-media accounts separately. Public social channels are useful for updates but should not be used to share account or payment details. Temporary product counts, customer counts, promotional Rewards rates and country-specific shipping discounts should remain on iHerb’s live site.
Customers should also verify expiration-sensitive or temperature-sensitive products promptly after delivery and report damage, leakage, missing seals or unexpectedly short shelf life through the authenticated order-support flow rather than disposing of the packaging before the issue is documented.
