iHerb is a global online retailer specializing in vitamins, dietary supplements, sports nutrition, beauty, personal care, grocery products, and other health and wellness essentials.
Founded in 1996, the company has developed an extensive catalog featuring thousands of products from established international brands, alongside its own collection of private-label products.
For shoppers, iHerb offers a convenient way to compare nutritional supplements, personal care products, and everyday wellness items in one online store. Its product range covers everything from basic vitamins and minerals to protein powders, probiotics, skincare, natural grocery products, and pet supplies.
But shopping for health and wellness products requires more than comparing prices. Customers should understand product labels, ingredients, serving sizes, quality documentation, import restrictions, and return conditions before placing an order.
This guide explores what iHerb offers, how its shopping experience works, and what customers should consider before buying.
Editorial note: This article evaluates iHerb as an online retailer based on publicly available company information and policies. CatchOffers has not independently tested the products sold on the platform. Product quality, suitability, and performance vary by brand and individual item.
What Is iHerb?
iHerb is an online health and wellness retailer founded in Pasadena, California, in 1996. The company is currently headquartered in Irvine, California, and serves customers across international markets.
According to its official website, iHerb offers more than 50,000 products from over 2,000 brands and serves customers in more than 180 countries.
Its main product categories include:
- Vitamins and dietary supplements.
- Sports nutrition and fitness products.
- Beauty and skincare.
- Bath and personal care.
- Grocery and natural food products.
- Baby and children’s products.
- Home and pet supplies.
One important distinction is that iHerb operates as a retailer rather than a conventional third-party marketplace.
The company states that products are sold and shipped directly by iHerb, rather than by independent third-party sellers. It also says it sources products from brands and authorized distributors.
This centralized retail model gives iHerb greater control over order fulfillment and product handling than a marketplace where different sellers manage their own inventory and shipping.
However, shoppers should still evaluate each product and manufacturer individually. A large retail selection does not mean every item has undergone the same independent testing or carries identical quality certifications.
What Can You Buy at iHerb?
iHerb organizes its catalog into several major categories, allowing customers to browse by product type, brand, ingredient, lifestyle, or shopping need.
1. Vitamins and Dietary Supplements
Supplements are one of iHerb’s core product categories.
The selection includes products such as:
Vitamins
- Vitamin C.
- Vitamin D.
- Vitamin E.
- Vitamin K.
- B-complex vitamins.
- Multivitamins.
- Formulas for different age groups.
Minerals
- Magnesium.
- Calcium.
- Zinc.
- Iron.
- Selenium.
- Other mineral formulas.
Herbal and plant-based supplements
- Turmeric and curcumin.
- Ashwagandha.
- Milk thistle.
- Elderberry.
- Herbal blends.
- Adaptogens.
Specialized supplement categories
- Omega-3 and fish oil.
- Probiotics.
- Digestive enzymes.
- Collagen.
- CoQ10.
- Antioxidants.
- Sleep and relaxation products.
- Hair, skin, and nail supplements.
Customers can compare products by ingredient, dosage, serving size, capsule count, formulation, and manufacturer.
When shopping for supplements, reading the Supplement Facts panel is especially important. Two products with similar names may contain different ingredient forms, concentrations, serving sizes, or additional ingredients.
A higher dosage is not automatically better, and a product’s marketing claims should not replace professional health advice.
2. Sports Nutrition
iHerb also offers a broad selection of sports nutrition products for people interested in exercise, fitness, and athletic performance.
Common categories include:
- Whey protein.
- Plant-based protein.
- Casein protein.
- Mass gainers.
- Creatine.
- BCAAs and essential amino acids.
- Pre-workout formulas.
- Electrolytes and hydration products.
- Protein bars and sports snacks.
- Recovery products.
Protein products come in different formulations, flavors, serving sizes, and ingredient combinations.
For example, whey protein and plant-based protein are not interchangeable for every shopper. People may choose between them based on dietary preferences, allergies, digestion, nutritional requirements, and taste.
Creatine products also vary in formulation and serving instructions. Customers should check the specific product label rather than assume every product under the creatine category has the same composition.
3. Beauty and Skincare
Beyond supplements, iHerb offers beauty and personal care products from a range of established and emerging brands.
The beauty selection may include:
- Facial cleansers.
- Moisturizers.
- Serums and facial treatments.
- Sunscreen.
- Face masks.
- Body care.
- Hair care.
- Natural and botanical skincare.
- Beauty accessories.
This category allows shoppers to purchase skincare alongside supplements and other wellness essentials.
When comparing beauty products, review the ingredients, product instructions, skin compatibility information, packaging size, and any relevant warnings.
Customers with sensitive skin or known allergies should pay particular attention to ingredient lists and patch-testing recommendations.
4. Bath and Personal Care
The Bath & Personal Care section includes everyday products for hygiene and body care.
Examples include:
- Body washes and shower products.
- Bar soaps.
- Body lotions.
- Hand creams.
- Body oils.
- Essential oils.
- Deodorants.
- Oral care.
- Haircare products.
- Personal hygiene items.
The category includes products from multiple brands and price ranges, making it useful for customers who want to consolidate different household purchases into one order.
5. Grocery and Natural Food Products
iHerb also sells grocery products, snacks, and specialty food items.
Depending on the destination market and current inventory, shoppers may find:
- Nuts and seeds.
- Dried fruit.
- Healthy snacks.
- Protein bars.
- Natural sweeteners.
- Tea and beverages.
- Organic food products.
- Specialty dietary foods.
- Baking ingredients.
This category is particularly useful for shoppers who want to combine supplement purchases with selected pantry and snack items.
Food products should still be reviewed for allergens, ingredients, storage instructions, and country-specific import restrictions.
6. Baby, Kids, Home, and Pet Products
The catalog extends beyond personal supplements and beauty products.
Other sections include:
Baby & Kids
- Selected baby care products.
- Children’s personal care.
- Family-related wellness items.
- Products designed for different age groups.
Home
- Selected household products.
- Natural cleaning and home care items.
- Everyday lifestyle essentials.
Pets
- Pet grooming products.
- Pet supplements.
- Cat and dog food and treats.
- Pet health and care products.
Availability varies by destination and product restrictions. Customers should check the delivery options for each item before adding it to an international order.
iHerb-Owned Brands
Although iHerb primarily operates as a multi-brand retailer, it also owns several product labels.
Its official website identifies the following brands:
California Gold Nutrition
California Gold Nutrition is iHerb’s flagship owned brand, focusing on supplements and wellness products.
Its catalog includes products across categories such as vitamins, minerals, fish oil, probiotics, collagen, and other nutritional formulas.
The brand is particularly visible across iHerb’s supplement range.
Mild By Nature
Mild By Nature offers products in areas such as personal care, beauty, and everyday wellness.
Its range includes selected products for customers interested in personal care and lifestyle essentials.
Idealove
Idealove is an iHerb-owned beauty and skincare brand.
Its products are positioned around skincare and personal care routines.
Vitacost
Vitacost is another brand within iHerb’s portfolio, associated with vitamins, supplements, and wellness products.
These owned brands provide iHerb with a product portfolio beyond its role as a distributor of third-party brands.
It is still important to compare individual products rather than assume all products from an owned brand have identical ingredients, testing procedures, or performance.
iHerb iTested: What Does the Quality Verification Program Mean?
Product quality is especially important when purchasing supplements online.
iHerb operates an independent testing program called iTested.
According to the company, selected products from its exclusive iHerb-owned brands undergo testing by independent third-party laboratories. These tests can verify factors such as:
- Ingredient identity.
- Ingredient potency.
- Purity.
- Label accuracy.
- Other product-specific quality parameters.
iHerb states that customers can view the applicable Certificate of Analysis (COA) on participating product pages.
This is useful because a Certificate of Analysis provides more specific information than a general marketing statement about product quality.
However, there is an important distinction: iTested applies to selected products, not automatically to every item sold on iHerb.
Customers should check the individual product page to see whether an iTested designation and relevant documentation are available.
The program should also not be confused with a universal regulatory approval or a guarantee that a supplement is suitable for every person.
For a particular product, the most useful information is the actual testing documentation, ingredient declaration, manufacturer information, and applicable quality standards.
How to Choose Products on iHerb
With thousands of products available, choosing the right item can be challenging.
The following checks can help make the shopping process more practical.
Step 1: Check the Supplement Facts or Ingredients Panel
Start with the product label.
For supplements, review:
- Active ingredients.
- Amount per serving.
- Recommended serving size.
- Number of servings per container.
- Other ingredients.
- Allergen information.
- Manufacturer instructions and warnings.
For skincare and personal care, review the full ingredient list and usage directions.
Step 2: Compare Similar Formulations
Products with similar names may have different formulations.
For example, magnesium supplements can use different forms, and protein powders may differ in their protein sources and added ingredients.
Compare the actual composition and serving size rather than relying on the headline product name.
Step 3: Review Product Documentation
Check whether the manufacturer provides a Certificate of Analysis, third-party testing documentation, certifications, or other supporting information.
If a product carries the iTested designation, review the relevant documentation on its product page.
Do not assume that certifications or testing claims from one product apply to the entire brand.
Step 4: Check Expiration or Best-By Information
iHerb states that expiration or best-by dates are displayed on product pages where applicable.
This is particularly relevant for supplements, packaged food, and products that may be stored for extended periods.
Customers should review the displayed date and consider how quickly they can reasonably use the product after delivery.
Step 5: Consider Brand Reputation and Customer Feedback
Customer reviews can help identify common shopping experiences, product preferences, taste feedback, packaging issues, and other practical details.
However, reviews are individual experiences rather than clinical evidence.
Positive customer feedback does not establish that a supplement treats a medical condition, and negative feedback does not automatically mean a product is defective.
Step 6: Consider Your Personal Requirements
A supplement that is suitable for one person may not be appropriate for another.
People who are pregnant, breastfeeding, taking medication, managing an existing medical condition, or considering supplements for children should consult a qualified healthcare professional before starting a new product.
iHerb Quality and Product Handling
iHerb states that its fulfillment network uses climate-controlled facilities designed to help preserve product freshness and quality.
The company reports operating nine climate-controlled fulfillment centers and inventory hubs across the United States, Asia, and the Middle East.
It also states that these facilities hold relevant industry registrations and GMP or ISO compliance credentials.
For shoppers, controlled storage can be an important consideration when buying products that may be sensitive to heat, humidity, or storage conditions.
However, facility standards should not be interpreted as proof that every individual item has been independently certified or tested.
For specific products, buyers should review the manufacturer information, product documentation, storage instructions, and testing details available on the product page.
iHerb Rewards Program
iHerb offers a Rewards program that allows eligible customers to earn Rewards Credit through referrals and approved product reviews.
This is different from a conventional loyalty program that automatically awards points for every dollar spent.
The program includes several earning opportunities:
Referral rewards
Customers can share a personalized Rewards link or code with eligible referrals. The published program terms currently describe 10% Rewards Credit for qualifying new-customer orders and 5% for qualifying returning-customer orders.
Product reviews
Eligible approved product reviews can also earn Rewards Credit. The current program FAQ states that participants can earn $1 per eligible approved review, subject to an annual limit and review requirements.
Expiration
Standard Rewards Credits earned from referrals and reviews have a 30-day validity period after issuance under the policy effective June 1, 2026. Promotional credits may have different terms.
It is important to read the current program rules because earning rates, approval conditions, and expiration dates can change.
The Rewards program is intended for customer referrals and is not a substitute for the separate iHerb Affiliate Program for publishers.
iHerb Shipping and International Delivery
iHerb serves international customers and operates regionalized storefronts with country-specific currencies, languages, payment methods, and shipping arrangements.
However, international delivery is not identical in every country.
Shipping availability can depend on:
- Destination country.
- Product category.
- Product ingredients or transportation restrictions.
- Local customs requirements.
- Import permits and regulations.
- Courier availability.
- Order value and package restrictions.
Customers should select their destination country before shopping and review the shipping information displayed for that market.
Important Update for Vietnam
At the time this guide was prepared, the Vietnamese iHerb website displayed the notice:
“Shipping to Vietnam is Temporarily Unavailable.”
The Vietnam shipping information page still displayed SF Express and certain shipping and customs details, while older shopping guidance referred to a free-shipping threshold.
Because the current page displays a temporary shipping suspension, older delivery methods and free-shipping information should not be treated as confirmation that new orders can currently be shipped to Vietnam.
Customers in Vietnam should check the live destination page and checkout availability before planning a purchase.
When service resumes, shipping costs, delivery estimates, product restrictions, and customs requirements should be confirmed using the details displayed at that time.

iHerb Returns and Refunds
iHerb provides an online return and refund process, but return periods and conditions vary by product category and purchase channel.
Its published policy currently describes:
| Product type | Return window when purchased directly from iHerb |
|---|---|
| Most products | 30 days |
| Eligible iHerb-owned-brand products | 90 days |
The extended 90-day period applies to qualifying iHerb-owned-brand products purchased directly through iHerb.com or its app. Purchases through other platforms have different terms.
How to Request a Return
The return process generally involves:
- Sign in to the iHerb account.
- Open the Orders page.
- Select Refunds/Returns for the relevant order.
- Choose the product and submit the request.
- Follow the instructions provided after the request is reviewed.
Submitting a request does not guarantee approval. iHerb reviews requests individually and may require additional information or product documentation.
Some cases may be resolved using photographs without requiring the customer to ship the product back. Customers should wait for the official return instructions before discarding or sending anything.
International Return Conditions
International returns have additional limitations.
iHerb states that:
- Prepaid return labels are not provided for international orders.
- Customers are responsible for international return shipping costs.
- Refund amounts may differ because of return postage, exchange rates, handling, or customs fees.
- Some unclaimed or refused shipments may be destroyed by carriers and cannot be refunded.
The company also states that international refunds to the original payment method can take up to 35 days to appear.
Customers outside the United States should consider these conditions before ordering products that may be difficult or expensive to return.
Read the complete iHerb Returns & Refunds Policy for current details.
iHerb Advantages and Limitations
Potential Advantages
Large product selection: iHerb offers thousands of wellness, supplement, beauty, personal care, and grocery products across multiple brands.
Multi-brand shopping: Customers can compare products from different manufacturers in one retail environment.
Direct retail fulfillment: iHerb states that orders are sold and shipped directly by the company rather than independent marketplace sellers.
Dedicated owned brands: California Gold Nutrition, Mild By Nature, Idealove, and Vitacost provide additional product options.
Selected independent testing: The iTested program provides supporting documentation for participating products.
International reach: iHerb operates regional storefronts and has served customers across a large number of countries, although individual destinations may experience service restrictions.
Points to Consider
Product suitability varies: A product’s ingredients, dosage, formulation, and manufacturer matter more than the general reputation of the retailer.
Not every item is independently tested: The iTested program applies to selected products, so customers should verify testing information individually.
International shipping is destination-specific: Some countries may have product restrictions, customs requirements, or temporary shipping suspensions.
International returns can be expensive: Customers are responsible for return shipping, and prepaid labels are not available for international orders.
Rewards have restrictions: Referral credits and review rewards are subject to eligibility requirements and expiration rules.
Is iHerb Worth Considering?
iHerb is worth considering for customers who want to compare vitamins, dietary supplements, sports nutrition, skincare, personal care, grocery products, and other wellness essentials from multiple brands.
Its main strength is the breadth of its catalog combined with a centralized retail and fulfillment model.
The iHerb-owned brand portfolio and selected iTested products provide additional options for shoppers who want to review product documentation before purchasing.
However, customers should not assume that all supplements have the same quality, formulation, or suitability simply because they are sold on the same platform.
Read product labels carefully, compare ingredient amounts and serving sizes, review available testing documentation, and seek professional advice when necessary.
International shoppers should also verify current shipping availability and return conditions for their destination before placing an order.
For customers in an eligible delivery market, iHerb provides a broad online shopping destination for health, nutrition, beauty, and everyday wellness products.
