iHerb

Shopping iHerb? Pick your items, then check out through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. For US-origin vitamin and supplement brands (California Gold Nutrition, Sports Research, NOW Foods, Optimum Nutrition, Solgar, Nature's Way, Doctor's Best), iHerb is typically the cheapest per-unit route into Singapore because it ships direct from US warehouses without a local distributor markup, and its Trial Prices, Weekly Specials and Rewards Credit lower everyday pricing. Local wellness retailers (Watsons, Guardian, GNC, Unichi at pharmacy counters) can undercut on Singapore-registered SKUs during their own promotions but rarely on the same US-origin brands.

The main differences are in how iHerb sells to Singapore: it is a US online retailer founded in 1996 that ships from its own logistics centres in the US, South Korea, Hong Kong and Saudi Arabia, and it sources directly from brands and authorised partners, with no third-party sellers. iHerb collects Singapore's 9% GST when you pay, so no courier bill follows, and when iHerb runs free shipping it applies above a minimum spend. Whether it beats a pharmacy price on a given product depends on the promotions running that week, so compare the final S$ total. Before you pay on sg.iherb.com, go through ShopBack so part of the order comes back as cash, which lowers the effective price.

In Singapore it depends on the product and the week, so compare the final S$ price for the same brand, size and count: iHerb collects Singapore GST when you pay and ships free above a minimum spend when that offer runs, while Guardian and Watsons let you buy the same day in store. iHerb is the one to check for brands that are not sold locally, and it blocks products Singapore Customs prohibits, such as DHEA. If iHerb wins, go through ShopBack Singapore before you pay on sg.iherb.com to earn Cashback.

When iHerb runs free shipping to Singapore, it applies once your order reaches the minimum spend shown on its Singapore shipping page and in your cart, so the way to get it is to combine what you need into one order above that line. Orders go by tracked couriers such as Ninja Van, Singapore Post, CJ Singapore Express and SF Express, each with its own order value and weight limit, and Singapore GST is collected when you pay. Free shipping and going through ShopBack before you pay work together: one cuts the delivery cost and the other lowers the effective price of the products.

Yes, iHerb is a long-established US retailer, founded in 1996 and serving customers in over 180 countries, and its Quality Promise says it works directly with brands and authorised partners with no third-party sellers. Brands must supply Certificates of Analysis for supplements, selected products are tested by accredited third-party labs under its iTested programme, stock is kept in climate-controlled GMP, ISO and NSF certified fulfilment centres, and product pages show exact expiry dates. For Singapore, iHerb collects GST when you pay and blocks items Singapore Customs prohibits. Order on sg.iherb.com after going through ShopBack, since ShopBack's iHerb terms count orders placed on that site and shipped to Singapore.

iHerb typically issues its own sitewide promo codes on rotation, with SG-facing minimum-spend codes running through the year and mid-year Carnival window codes during 7.7. Specific codes rotate. The current Cashback is shown on this page before you check out.

iHerb runs a Rewards Credit programme where new customers can apply a referral code at sign-up to unlock a first-order welcome credit, and referrers receive a share of qualifying-order value as store credit usable on future orders. Referral credit and iHerb's sitewide promo codes are applied at checkout on iherb.com. The current Cashback is shown on this page before you check out.

iHerb's Trial Prices (also referred to as Trial Products) are limited-time first-time discounted prices on selected brands or SKUs, designed to let shoppers try a new product at a lower entry price. Trial-priced items often do not accept a sitewide promo code. Trial-priced items can earn Cashback when you go through ShopBack Singapore before you pay, alongside regular-price items in the same cart.

iHerb typically participates in the 11.11 and 12.12 windows with sitewide sale coding, brand-spotlight discounts on California Gold Nutrition, Sports Research, NOW Foods and Optimum Nutrition, and eligible Weekly Specials on wellness staples (multivitamins, omega-3, collagen, protein powder). Depth varies year to year, and Trial Prices on individual SKUs may sit outside the sitewide code. Go through ShopBack Singapore on the iHerb page above before you pay to earn Cashback on the 11.11 or 12.12 price.

For per-serve pricing on whey and plant protein in Singapore, iHerb typically has the widest catalogue and the most competitive per-unit prices on US-origin brands (California Gold Nutrition whey isolate, Sports Research whey and plant blends, NOW Foods sports whey, Optimum Nutrition Gold Standard). Larger tubs deliver a lower per-serve cost, and Trial Prices on newer brands can undercut everyday pricing on a first purchase. Local sports-nutrition retailers can undercut on Singapore-registered SKUs during their own promotions. Route through ShopBack Singapore on the iHerb page above before clicking through to iherb.com.

For daily wellness vitamins (multivitamin, vitamin D3, B-complex, magnesium, omega-3 fish oil, probiotics), California Gold Nutrition and NOW Foods are typically the cheapest per-unit routes on iHerb for Singapore shoppers because they are in-house or long-tenure catalogue brands priced against everyday demand. Trial Prices on a first-time SKU can lower the entry price further, and adding a sitewide iHerb-issued code above its qualifying spend threshold reduces the checkout total on regular-price items. Activate ShopBack Singapore before clicking through to iherb.com.

The strongest value windows for iHerb Singapore are typically the 7.7 Mid-Year Carnival, 9.9, 11.11, Black Friday, 12.12 and end-of-year clearance, when sitewide iHerb-issued codes usually run alongside Weekly Specials and Rewards Credit. Between headline events, Weekly Specials refresh brand and SKU discounts on rotation, and Trial Prices offer first-time entry pricing on selected products throughout the year. For time-critical restocks, going through ShopBack Singapore first still lowers what you pay at non-sale prices.

iHerb has historically offered an Auto-Delivery mechanic that lets shoppers schedule repeat orders of daily wellness staples (multivitamin, vitamin D3, magnesium, omega-3, protein powder) at a lower recurring price than one-off ordering. Availability, discount and category eligibility vary by market and by product. For Cashback, place one-off orders on iherb.com after going through ShopBack Singapore.

iHerb's Rewards Credit is a merchant loyalty mechanic that returns a percentage of order value as store credit usable on future orders, and referred new customers unlock a first-order welcome credit at signup via a referral code applied at checkout. Rewards Credit is a merchant account benefit on iherb.com; the current Cashback is shown on the iHerb page on ShopBack Singapore before you check out.

iHerb is a US-based online retailer of vitamins, supplements, sports nutrition, beauty, personal care, baby, grocery and pet wellness products, founded in 1996. iHerb sells third-party brands (NOW Foods, Solgar, Nature's Way, Optimum Nutrition, Doctor's Best) alongside its own in-house labels California Gold Nutrition (CGN) and Sports Research, and ships direct to Singapore from temperature-controlled US warehouses. Buying through ShopBack Singapore earns Cashback on orders at iHerb's Trial Prices and Weekly Specials.

iHerb ships direct to Singapore from US warehouses with multiple carrier options at checkout, and delivery timing varies by carrier and order weight. Free shipping thresholds also vary by carrier and order weight, so the current qualifying minimum is best confirmed at iHerb checkout. Certain supplements, herbal products and ingredients may be restricted under Singapore Health Sciences Authority (HSA) rules, and goods imported to Singapore may attract GST and import treatment based on prevailing rules and order value. Activate ShopBack Singapore before clicking through to iherb.com.

To earn Cashback on iHerb Singapore, go through ShopBack Singapore before you pay and the Cashback goes to your ShopBack account: sign in, open the iHerb page and click through to sg.iherb.com to complete the purchase. The live rate is shown on this page, and when an upsize runs, the higher rate shows here too.

On your phone, open iHerb from the ShopBack app and finish the order there. For each restock, start again from ShopBack before you pay.

iHerb Cashback confirms in your ShopBack account after iHerb's return and validation window, within the tracking and confirmation times shown on this page. Track status under the Orders tab in the ShopBack app or web account.

Yes. iHerb has operated as a US-based online wellness retailer since 1996, sources directly from brand owners or authorised distributors, and ships to Singapore from temperature-controlled US warehouses. Certain supplements, herbal products and ingredients may be restricted under Singapore Health Sciences Authority (HSA) rules, and goods imported to Singapore may be subject to GST and import treatment based on prevailing rules and order value. Route through ShopBack Singapore before clicking through to iherb.com.

iHerb is a US online retailer founded in 1996 that sells vitamins, supplements, sports nutrition, beauty and K-beauty, personal care, grocery, baby and pet wellness products, shipping from nine fulfilment centres and inventory hubs to more than 180 countries, per sg.iherb.com. Singapore shoppers use sg.iherb.com, priced in SGD, with free shipping on orders over SG$30 (as listed on iHerb's site in October 2026). It carries third-party brands such as NOW Foods, Solgar, Optimum Nutrition and Doctor's Best alongside its own labels California Gold Nutrition and Sports Research. The ShopBack iHerb page lists the Cashback rate for orders placed on sg.iherb.com and shipped to Singapore.

Start from the iHerb page on ShopBack Singapore in the ShopBack app, on shopback.sg or via the browser extension, click through and complete the order on sg.iherb.com. The Cashback confirms once iHerb's return window has passed. Cashback applies to orders placed on sg.iherb.com and shipped to Singapore.

The ShopBack Singapore offer on iHerb has two parts. Cashback: at the live rate shown on the ShopBack iHerb page, paid after confirmation. Upsize: when an upsize runs, the higher rate shows on this page. No discounted iHerb gift card is sold by ShopBack Singapore.

On a S$150 supplements basket on sg.iherb.com, going through ShopBack Singapore before you pay makes your effective price S$150 minus the Cashback at the live rate on the ShopBack iHerb page, paid to your bank or PayNow after confirmation. Shipping is free because the order is over SG$30, the free-shipping threshold listed on iHerb's site in October 2026.

Sign in to ShopBack Singapore, open the iHerb page and click through to sg.iherb.com, then build your cart and pay there. Tracking and confirmation follow the times shown on this page. Start again from ShopBack for every new order.

Cashback on iHerb orders made through ShopBack Singapore confirms after iHerb's return window. Confirmed Cashback is withdrawn to a Singapore bank account or by PayNow from the ShopBack app.

Shopping iHerb? Pick your items, then check out through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. iHerb runs its own sitewide sale codes on sg.iherb.com, alongside Weekly Specials and brand discounts that apply automatically. The current Cashback is shown on this page before you check out.

Go through ShopBack Singapore before you pay, then shop iHerb's Weekly Specials and brand sale prices as usual; shipping is free over SG$30 (as listed on iHerb's site in October 2026). Trial Prices apply at product level, though a trial-priced item may not accept a code. Place one-off orders on sg.iherb.com.

iHerb's deepest windows are the mid-year 7.7 Carnival, 9.9, 11.11, Black Friday (27 November 2026), 12.12 and year-end clearance, when sitewide pricing tends to drop. Between events, Weekly Specials rotate brand discounts every week, so check before each planned restock. For a routine restock, going through ShopBack Singapore first lowers what you pay even at non-sale prices; see the Singapore 2026 sale calendar.

Pick iHerb for US-origin brands (California Gold Nutrition, NOW Foods, Solgar, Doctor's Best) and for per-unit price on large bottles, since there is no local distributor markup and shipping is free over SG$30 (as listed on iHerb's site in October 2026); expect a few days' wait. Pick Guardian or Watsons when you need it today, want a Singapore-registered label such as Blackmores or Swisse, or are using a member-day voucher on those brands. For a monthly multivitamin and vitamin D restock, iHerb usually wins on price; for a one-off urgent buy, the pharmacy wins. Check the rate on the ShopBack iHerb page, or on Guardian's ShopBack page, before paying.

Pick iHerb: the supplement range is deeper, free shipping starts at SG$30 versus Amazon SG's S$60 International Store threshold for non-Prime (as listed on each site in October 2026), returns run 30 days (90 on iHerb brands), and Cashback tracking and confirmation times are shown on this page. Pick Amazon SG when you are a Prime member bundling supplements with electronics or books, or when a specific brand is Amazon-exclusive. Both charge 9% GST at checkout and neither leaves a courier bill. Rates are on the ShopBack iHerb page and the Amazon page.

Pick iHerb when the brand is US-origin and you want it shipped sealed from iHerb's own warehouse with a 30-day return. Pick Shopee Mall or LazMall when the brand has an official Singapore store there (Blackmores, Swisse, Centrum) and a voucher day or free-shipping offer is running, or when you need delivery within two days. For Korean skincare specifically, Shopee and Lazada official brand stores usually match or beat iHerb. Compare the final price on each platform after Cashback; the iHerb rate is on the ShopBack iHerb page.

For US-origin supplements, iHerb is normally the cheapest per unit in Singapore because it ships direct from US warehouses with free shipping over SG$30 (as listed on iHerb's site in October 2026) and no local distributor margin, and its house brands California Gold Nutrition and Sports Research are priced below equivalent NOW or Solgar lines. Local pharmacies (Guardian, Watsons, GNC) undercut on Singapore-registered labels during member days but rarely on the same US brands. Add Cashback from ShopBack Singapore at the rate on the ShopBack iHerb page to the comparison; the breakdown is in our iHerb Singapore worth-it analysis.

For a daily routine (multivitamin, vitamin D3, B-complex, magnesium, zinc, vitamin C), California Gold Nutrition and NOW Foods are consistently the lowest per-capsule lines on iHerb, with Solgar and Thorne at the premium end. Buy the 180 or 360 count where it exists; the per-dose saving is larger than any code. HSA does not license health supplements for personal import, but they must not contain prohibited medicinal ingredients, and standard vitamins from these brands are routine imports.

Yes for price and range: fish oil (Sports Research, Nordic Naturals, California Gold Nutrition), probiotics (Garden of Life, Culturelle, Jarrow) and collagen (Vital Proteins, Sports Research) on iHerb are typically cheaper per serving than pharmacy equivalents in Singapore and ship from temperature-controlled warehouses. Probiotics that need refrigeration are a risk in transit in a tropical climate, so prefer shelf-stable strains. Free shipping over SG$30 (as listed on iHerb's site in October 2026) and 9% GST at checkout apply.

iHerb carries COSRX, Beauty of Joseon, Mizon, Some By Mi and US lines such as CeraVe and Thayers, with 9% GST at checkout and free shipping over SG$30 (as listed on iHerb's site in October 2026). Prices are competitive on US brands; on Korean brands, official stores on Shopee and Lazada often match or beat iHerb on voucher days, as covered in our COSRX vs Beauty of Joseon vs SKIN1004 snail mucin comparison. Returns need sealed packaging. For a deeper look, see Save on Beauty & Skincare.

iHerb's grocery aisle (protein bars, nut butters, chia, matcha, stevia, teas, Quest and RXBAR) is a common add-on to clear the SG$30 free-shipping threshold (as listed on iHerb's site in October 2026) and is often cheaper than the same imported brands at Cold Storage or Redmart. Food imports fall under Singapore Food Agency rules rather than HSA; packaged snacks and supplements are routine, while meat and dairy products are not.

iHerb sells kids' multivitamins, probiotics, baby skincare and feeding accessories, and these ship like any other order with free shipping over SG$30 (as listed on iHerb's site in October 2026) and 9% GST at checkout. Infant formula is a regulated food import in Singapore and some formulas cannot be shipped; iHerb removes unavailable items at checkout for a Singapore address. For diapers and formula, Amazon SG or Shopee Supermarket is the better route.

Yes, iHerb ships pet probiotics, joint support, calming chews and grooming products to Singapore. Pet health product imports fall under Animal and Veterinary Service rules, and iHerb hides items it cannot ship to Singapore. Pet food is not a strength of iHerb's range; Shopee or Lazada are better for bulk kibble.

iHerb's subscription (shown as Subscribe and Save on sg.iherb.com) gives a recurring discount in exchange for scheduled deliveries. One-off orders placed through ShopBack earn Cashback, so if you prefer Cashback, set your own reminder and reorder through ShopBack each time; if the subscription discount suits you better for an item, subscribe for that item. For a deeper look, see Save on iHerb.

iHerb Rewards is iHerb's own loyalty mechanic: a share of order value comes back as credit, and new customers can apply a referral code at signup for a first-order credit. It is separate from ShopBack Cashback, which is paid as cash when you go through ShopBack Singapore before you pay.

Yes. Trial Prices are limited first-time discounted prices on selected products on sg.iherb.com, applied on the product page rather than by code, and trial-priced items earn Cashback. A trial-priced item may not accept a further code, and iHerb limits trial quantities per account. Regular-price items in the same basket track normally.

As listed on sg.iherb.com in October 2026, shipping is free on orders over SG$30; below that a carrier fee shows at checkout and varies by weight. iHerb states that most of its orders worldwide arrive within 2 to 6 days, and the estimated date for your Singapore address appears at checkout before payment. Heavy protein tubs can move a parcel into a higher weight band or restrict carrier options.

Singapore's Health Sciences Authority does not license or pre-approve health supplements for import, manufacture or sale, so ordering vitamins, minerals, fish oil, probiotics or protein from iHerb for your own use needs no permit. What HSA does prohibit is supplements containing medicinal ingredients (for example steroids or substances controlled under the Poisons Act and Misuse of Drugs Act) and ingredients on its restricted list, and it sets limits on heavy metals and certain vitamin doses. Prescription medicines are a different category and cannot be freely ordered. iHerb hides products it cannot ship to a Singapore address, but you remain responsible for what you import.

Yes. Singapore applies GST to imported low-value goods (S$400 and below) as well as higher-value imports, under IRAS rules in force since 1 January 2023, and the rate has been 9% since 1 January 2024. GST-registered overseas sellers collect it at checkout rather than leaving a bill with the courier. On sg.iherb.com the tax line appears in the order summary before you pay.

As listed on sg.iherb.com/info/returns in October 2026: most products can be returned within 30 days of delivery and iHerb house brands (California Gold Nutrition, Sports Research and others) within 90 days; you submit the request from your Orders page, iHerb responds within 48 hours, and approved items must be sent back within 14 days. iHerb does not provide return labels for international orders, so return postage from Singapore is yours, and refunds take 7 to 10 business days to the original payment method. ShopBack Singapore confirms Cashback once iHerb's return window has passed, within the confirmation times shown on this page.

iHerb has sold health and wellness products online since 1996, sources from brand owners or authorised distributors, and ships to Singapore from its own temperature-controlled fulfilment centres, per sg.iherb.com. It publishes a 30-day return policy (90 days on house brands), accepts over 40 local payment methods across its markets and prices Singapore orders in SGD with 9% GST at checkout.

iHerb is the right pick when you want US-origin supplements, protein or clean-beauty brands at per-unit prices below Singapore pharmacies, when your basket clears the SG$30 free-shipping threshold (as listed on iHerb's site in October 2026), and when you can wait a few days. It is also the pick for mixed baskets (vitamins plus snacks plus skincare) that would otherwise be split across three stores. Start from the ShopBack iHerb page before you pay and earn Cashback at the rate shown.

Skip iHerb when you need the product today (Guardian, Watsons), when you want a Singapore-registered brand like Blackmores on a pharmacy member day, when you are buying house-brand whey in bulk (Myprotein sales usually win per serve), or when the item is infant formula or a refrigerated probiotic that may not travel well. For Korean skincare on a voucher day, Shopee official stores often beat iHerb. For everything else, go through the ShopBack iHerb page before you pay.

iHerb is often cheaper because it sells online only at global scale, shipping from nine fulfilment centres and inventory hubs to more than 180 countries, while shops in Singapore pay for physical stores, staff and local stock. It sources from brand owners and authorised distributors, ships free to Singapore on orders over SG$30 and collects the 9% GST when you pay, so no courier bill follows, per sg.iherb.com. It is not cheaper every time: a small order below the free-shipping threshold, a product that cannot be shipped to Singapore or something you need today can tip the balance to a local store, so compare the final total. Before you check out on iHerb, go through ShopBack. For a deeper look, read why iHerb is often cheaper.

For most iHerb orders, yes: going through ShopBack Singapore is an essential step before you check out, so you pay less on the same order. Open iHerb from this page, then build your cart and pay on sg.iherb.com. What comes back is cash, not points or iHerb Rewards credit, so it works like a discount on the order price after you pay. Check the live rate on this page.
