iHerb is one of the world’s largest online retailers for vitamins, supplements, and natural health products, shipping to over 180 countries from its California warehouses. This page covers how iHerb works, what’s worth buying, how to navigate returns, and how to reach customer support when something goes wrong.
Founded in 1996 and headquartered in Irvine, California, iHerb has grown from a small operation into a $2.9 billion business (fiscal 2025) serving 15 million customers worldwide. Its catalog spans over 50,000 products across thousands of brands – a scope that makes it a go-to source for health-conscious shoppers who want variety and competitive pricing in one place.
What is iHerb?
iHerb sells vitamins, minerals, supplements, sports nutrition, natural beauty, and health foods – all shipped directly from temperature-controlled warehouses in the United States. The company operates its own branded product line under the “iHerb Brands” label, alongside thousands of third-party brands. It supports 36 languages and 40 localized payment methods, which explains its strong customer base outside the US.
One of iHerb’s distinguishing features is its iTested quality program. Products carrying the iTested seal have been independently tested by accredited US laboratories for identity, purity, and potency. Test results are published online by batch, so you can look up the certificate of analysis for a specific product before buying. This level of transparency is uncommon in the supplement industry.
iHerb also runs an Autoship & Save subscription service. You set a recurring delivery schedule for products you buy regularly, lock in the lowest discounted price, and can pause, skip, or cancel at any time with no fees or penalties.
Is iHerb Legit and Safe?
iHerb is a legitimate, established retailer with a track record going back nearly 30 years. It holds an A+ rating from the Better Business Bureau (BBB) and has been BBB accredited since November 2023. On Trustpilot, iHerb scores 3.9 out of 5 from over 11,000 reviews (as of March 2026) – a solid but not exceptional score. The most common complaints involve delayed shipments, slow customer service responses, and occasional issues with return requests.
The iTested program adds a layer of accountability for iHerb brand products specifically. Independent laboratory testing means you’re not just taking the brand’s word for what’s in the bottle. For third-party brands, iHerb sources directly from manufacturers and claims to verify authenticity – though the same independent verification does not apply as it does to their own brand.
For safety-conscious shoppers, the main practical advice is to check the iTested seal on iHerb brand products, read customer reviews for specific items (iHerb only allows reviews from verified purchasers), and check the expiration date on delivery – some customers report receiving products close to expiry.
Product Variety and Quality
iHerb carries over 50,000 products across vitamins, minerals, herbal supplements, sports nutrition, beauty, personal care, baby products, pet health, and natural groceries. The range is wide – you can find mainstream US brands alongside smaller specialist labels that aren’t stocked in regular pharmacies or health stores. In fiscal 2025 alone, iHerb added more than 9,000 new products and 230 new brands to its catalog.
Product quality varies by brand, as with any large marketplace. iHerb brand products (California Gold Nutrition, Sports Research, and others) tend to be significantly cheaper than equivalent name brands and carry the iTested certification. For third-party brands, the usual supplement-shopping rules apply: look for products with USP, NSF, or other third-party certifications listed on the label.
Best Things to Buy on iHerb
Hair Care and Beauty
iHerb’s beauty and personal care section carries a wide range of natural hair care brands that are hard to find outside specialty health stores. Look for brands like Andalou Naturals, Acure, and Dessert Essence for shampoos, conditioners, and styling products without sulfates or parabens. Prices are typically 20-40% lower than equivalent products at Whole Foods or similar retailers.
Biotin supplements, collagen peptides, and hair growth vitamins are also popular on iHerb. The iHerb brand collagen peptides (California Gold Nutrition) are a particularly good value and carry the iTested certification.
Supplements
This is iHerb’s core strength. The supplement catalog covers everything from basic multivitamins and vitamin D to specialized stacks for sleep, stress, immunity, and gut health. iHerb brand supplements like California Gold Nutrition’s Vitamin D3, Omega-3, and Magnesium Glycinate are consistently well-reviewed and priced well below comparable products from national pharmacy chains.
For probiotics, iHerb’s refrigerated shipping options and controlled warehousing conditions make it a better option than buying from a general retailer where temperature control during transit is less reliable. Garden of Life, Jarrow Formulas, and Renew Life are consistently popular brands in this category.
Sports Nutrition
Sports Research, Optimum Nutrition, and Dymatize are well-represented on iHerb. The iHerb brand Sports Research line covers protein powders, creatine, BCAAs, and pre-workout supplements at prices that undercut most dedicated sports nutrition stores. Creatine monohydrate and whey protein from iHerb brand labels are among the highest-selling products on the site.
One tip for sports nutrition shoppers: the bulk sizes on iHerb generally offer better value per serving than the smaller containers, and Autoship & Save brings further savings if you buy the same products regularly.
How to Order on iHerb
Ordering on iHerb is straightforward. Create an account at iherb.com, browse by category or search by product name or brand. Product pages show full ingredient lists, serving sizes, certifications, and customer reviews – all verified from actual purchases. Add items to your cart, select your shipping preference, and check out.
iHerb accepts Visa, Mastercard, American Express, Discover, JCB, PayPal, Apple Pay, iDEAL, WeChat Pay, and AliPay (availability varies by country). Shipping costs and estimated delivery times are shown at checkout before you pay. You can also use the mobile app on iOS and Android, which offers exclusive discounts not always available on the website.
If you buy the same products regularly, set up Autoship & Save from any product page. This locks in the sale price permanently and handles delivery on your chosen schedule. Modify or cancel anytime through your account settings – there’s no minimum commitment.
iHerb Returns and Refunds
Most iHerb products are eligible for return within 30 days of the date you receive them. iHerb brand products have a more generous 90-day return window. Items must be returned in their original condition and packaging.
To start a return, log into your account and submit a return request through the help center at information.iherb.com. A support agent will review the request within 48 hours. If approved, you have 14 days to ship the package back. Store credit is typically issued within 24 hours of approval. Refunds to your original payment method take 7-10 business days within the US, or up to 35 days for international customers.
iHerb also offers a Triple Guarantee on iHerb brand products, covering product purity, freshness, and label accuracy. If a product fails to meet these standards, contact customer service directly.

The results – including the full certificate of analysis – are published online at iherb.com/info/itested, so you can verify what was in the specific batch you received.

Can I cancel an iHerb order after placing it?

Tips for Shopping on iHerb
- Look for the iTested seal on iHerb brand products – it means the batch was independently lab-tested and results are publicly available.
- Use Autoship & Save for any product you buy more than once – it locks in the sale price and handles reordering automatically with no minimum commitment.
- Download the iHerb app on iOS or Android for exclusive discounts not always shown on the website.
- Check the product’s expiration date in the listing before ordering – most listings show the estimated shelf life remaining at time of shipment.
- Sort reviews by “Most Recent” and filter to your country for the most relevant shipping and experience feedback.
- Use the live chat during weekday hours (6am-6pm PST) for the fastest resolution on order issues – written support can take longer.
- For returns, submit the request as soon as possible. The 30-day clock starts from the date you received the order, not the order date.
- Stack a promo code with Autoship & Save for the biggest discounts – first-time orders often qualify for an additional percentage off.
