iherb.com
iHerb.com is a large global online store for vitamins, supplements, beauty products, groceries, personal care items, and other health and wellness products.
What is iHerb.com used for?
iHerb.com helps people buy health and wellness products online from many well-known brands in one place.
The company started in California in 1996 and has grown from a small online supplement business into a major international retailer.
Its catalog now includes more than 50,000 products from over 2,000 brands.
Popular categories include vitamins, minerals, sports nutrition, skincare, bath products, healthy foods, baby care, and pet products.
This wide range makes iHerb useful for shoppers who would otherwise need to visit several specialist stores.
How big is iHerb today?
According to the company's corporate website, iHerb serves customers across more than 180 countries.
The platform supports many languages, currencies, payment methods, and international shipping options.
iHerb also says it has more than 16 million active customers and over 60 million customer product reviews.
The business reported $2.9 billion in net sales for fiscal 2025, which was 19 percent higher than the previous year.
It also fulfilled more than 44 million orders during that year.
In January 2026, iHerb expanded its U.S. business by acquiring Vitacost from Kroger.
Does iHerb sell products from third-party sellers?
One important difference between iHerb and large marketplaces is that iHerb says products on its site are sold and shipped by iHerb rather than unknown third-party marketplace sellers.
The company's About page says products come from brands and authorized distributors.
This model can make product sourcing easier to understand than on marketplaces where dozens of independent merchants may sell the same item.
It is especially relevant for supplements and skincare because buyers often care about authenticity, storage, freshness, and expiration dates.
How does iHerb handle product quality?
iHerb introduced its Quality Promise in 2026 to put more attention on sourcing, product documentation, storage, and testing.
The company says its products are supported by quality information that can include Certificates of Analysis.
It also operates climate-controlled fulfillment facilities that follow standards such as GMP, ISO, or NSF requirements depending on the facility.
Some products receive additional independent testing, although shoppers should not assume every product has been tested in exactly the same way.
These controls are useful trust signals, but they do not replace advice from a doctor when a supplement may affect a health condition or medicine.
Are iHerb reviews useful?
iHerb says its product reviews come from customers who actually ordered the reviewed products.
That gives shoppers a large pool of real-world comments about things such as taste, packaging, texture, size, and everyday use.
Still, customer reviews should not be treated as medical evidence because one person's experience does not prove that a supplement will work for someone else.
Independent feedback is also mixed rather than perfect.
At the time of this review, Trustpilot's iHerb page shows thousands of reviews, with many shoppers praising product choice and pricing while some report problems involving delivery, cancelled orders, returns, or customer support.
Is iHerb always cheaper than local stores?
iHerb often runs coupons, brand promotions, quantity discounts, and seasonal sales, but the listed product price is only part of the real cost.
International shoppers should compare the final checkout total with local prices because shipping, tax, customs charges, and currency conversion can change the result.
Import rules can also limit which supplements or quantities may enter a country.
The company's shipping information is therefore worth checking before placing a large international order.
A product that looks cheap on its page may become less attractive once every delivery cost is included.
What happens if you need a refund?
Under the current iHerb return policy, most products bought through iHerb.com or its app have a 30-day return window.
Eligible iHerb-brand products have a longer 90-day window when purchased directly through the site or app.
International customers should note that prepaid return labels are generally not provided for international returns.
Refund processing can also take longer for international orders than for domestic U.S. purchases.
Who is iHerb.com best for?
iHerb.com makes the most sense for shoppers who want a very large wellness catalog, access to international brands, verified-purchase reviews, and one checkout for several product categories.
Its biggest advantage is not simply low prices but the combination of selection, direct retail control, global fulfillment, and detailed product information.
Its main weakness is that international buying can become more complicated when shipping rules, customs, taxes, and returns are involved.
For that reason, the smartest way to use iHerb is to compare the final delivered price, check local import rules, read the ingredient label, and confirm that the product fits your actual needs before paying.
