iHerb

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 stack against 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. Activate ShopBack Singapore on this page, check the rate shown, then click through to iherb.com.

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, and the current ShopBack-featured code is shown on the iHerb page above. iHerb's own official codes are generally safer for ShopBack cashback tracking than third-party voucher codes, though stackability with Trial Prices and Weekly Specials varies by product. Activate ShopBack Singapore before clicking through to iherb.com and verify tracking after checkout.

iHerb runs a Rewards Credit program where new customers can apply a referral code at signup 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 typically applied at checkout on iherb.com; ShopBack Singapore cashback is a separate affiliate claim that lives outside iHerb's own account and can layer on top of an eligible order. Activate ShopBack Singapore on the iHerb page above before clicking through and verify tracking after checkout.

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 typically restrict stacking with sitewide promo codes and may not qualify for the same affiliate cashback treatment as regular-price items on iHerb, so stackability with ShopBack Singapore cashback is not guaranteed on trial line items. Regular-price items in the same cart usually track normally. Activate ShopBack Singapore before clicking through to iherb.com and verify tracking after checkout.

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 stacking-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. Route through ShopBack Singapore on the iHerb page above before checkout to earn cashback on top of 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 stacking 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 stack against 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, current-rate ShopBack Singapore cashback on the iHerb page above already offsets non-sale pricing.

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 rate and category eligibility vary by market and by product, and Auto-Delivery is a merchant-side subscription that typically applies before checkout price adjustments. Stackability with ShopBack Singapore cashback varies by promotion. Activate ShopBack Singapore before clicking through to iherb.com and verify tracking after checkout.

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; ShopBack Singapore cashback is a separate affiliate claim that layers on top of eligible orders and does not consume Rewards Credit. Stacking Rewards Credit, an iHerb-issued sitewide code and ShopBack cashback is a common pattern, though eligibility varies by product. Activate ShopBack Singapore before clicking through.

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 adds cashback on top of iHerb's own Rewards Credit, 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.

iHerb ships direct to Singapore from US warehouses with multiple carrier options at checkout, and delivery timing varies by carrier selection and order weight.

To earn cashback on iHerb Singapore, sign in to ShopBack Singapore, open the iHerb merchant page above and click through to iherb.com. Complete the purchase in the same browser session without switching to third-party coupon sites, and avoid pasting unsupported voucher codes at checkout since they can break tracking. iHerb-issued sitewide codes shown on the ShopBack iHerb page are generally safer for tracking than third-party codes. The cashback rate is shown on this page, and when an upsize runs, the higher rate shows on this page.

iHerb's own promotions (sitewide codes, Weekly Specials, Rewards Credit) and ShopBack Singapore cashback may be stackable on eligible orders, with cashback applied to the paid amount after any iHerb-issued discount. Stackability with Trial Prices varies since trial-priced SKUs often restrict promo-code stacking and may not qualify for the same affiliate treatment as regular-price items. Third-party voucher codes can break tracking. Activate ShopBack Singapore on the iHerb page above before clicking through and verify tracking after checkout.

For Singapore shoppers, the safest tracked route on mobile is the ShopBack Singapore app's in-app browser. Open ShopBack, tap the iHerb tile on the iHerb merchant page, and complete the order inside the same in-app browser session rather than hopping into the standalone iHerb app, since app-to-app deeplinks can strip affiliate parameters and break cashback tracking. Bookmarking iherb.com and returning through ShopBack for each restock keeps the click-through attribution intact on repeat wellness orders.

iHerb cashback shows as pending in your ShopBack account and moves to confirmed 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 fresh, and complete the order on sg.iherb.com in that session without applying iHerb Rewards credit, a referral code or any promo code that is not listed on ShopBack. The order shows as Pending in ShopBack and moves to Confirmed once iHerb's return window has passed, within the tracking and confirmation times shown on this page. Only orders placed on sg.iherb.com and shipped to Singapore qualify; orders placed inside the iHerb app do not.

The ShopBack Singapore offer on iHerb has three parts. Cashback: current, at the rate shown on the ShopBack iHerb page, paid after confirmation at day 40. Codes: ShopBack-featured iHerb codes are listed on this page, and because ShopBack lists them they stack with cashback. Upsize: when an upsize runs, the higher rate shows on this page, and upsizes tend to recur around 11.11 and 12.12. No discounted iHerb gift card is sold by ShopBack Singapore.

Take a S$150 supplements basket on sg.iherb.com. Apply a code featured on this page, for example one worth S$6 off a supplements order, and the subtotal drops to S$144. At the rate shown on the ShopBack iHerb page (a 5% example), cashback is S$7.20 on S$144, so the effective price is S$136.80, paid to your bank or PayNow after confirmation. Cashback is calculated on the product subtotal after discount and excludes GST, shipping and fees. 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, note any codes featured on this page, and click through to sg.iherb.com. Build your cart and pay in that session, using only the ShopBack-listed code, with no iHerb Rewards credit or referral code applied and without switching to the iHerb app. Tracking and confirmation follow the times shown on this page. Repeat the click-through for every new order.

Some iHerb orders do not earn cashback, including orders using iHerb Rewards, referral codes or promo codes not featured on ShopBack; the full list is in the Terms and exclusions section on this page. Orders must be placed on sg.iherb.com and shipped to Singapore. Rejected, cancelled, refunded, exchanged or returned orders also lose their cashback.

iHerb orders made through ShopBack Singapore show as Pending and then Confirmed within the tracking and confirmation times shown on this page, with confirmation following iHerb's return window. Confirmed cashback is withdrawn to a Singapore bank account or by PayNow from the ShopBack app. Exchange-rate movements can shift the tracked amount slightly, and a returned or refunded order is voided.

Yes. Per the Terms and exclusions section on this page, orders containing iHerb Rewards or promo codes not featured on ShopBack, and any store credit redemption, do not earn cashback, so applying Rewards credit, a friend's referral code or a code from a coupon site means the order will not earn cashback. iHerb's Weekly Specials, Trial Prices and on-site brand discounts do not void cashback because nothing is typed in; neither do the codes featured on this page. Decide per order: spend Rewards credit on one order without ShopBack, or earn cashback at the rate on the ShopBack iHerb page on another.

The ShopBack iHerb page features iHerb codes that stack with cashback, and the codes featured on this page show each code's discount and minimum spend. Both stack with cashback because ShopBack lists them. iHerb's own sitewide sale codes seen on sg.iherb.com or elsewhere are not listed on ShopBack and void cashback if used, as do referral codes and Rewards credit. Weekly Specials and brand discounts apply automatically and stack.

The stack that works is: an iHerb Weekly Special or brand sale price, plus one of the codes featured on this page, plus ShopBack cashback at the rate on the ShopBack iHerb page, with free shipping over SG$30 (as listed on iHerb's site in October 2026). Trial Prices apply at product level and do not block cashback, though a trial-priced item may not accept a code. What breaks the stack is iHerb Rewards credit, referral codes, non-ShopBack codes, Autoship and Save, or ordering in the iHerb app.

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 and ShopBack upsizes overlap. Between events, Weekly Specials rotate brand discounts every week and the codes featured on this page refresh over time, so check this page before each planned restock. For a routine restock, cashback at the rate on the ShopBack iHerb page already offsets non-sale pricing; 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 stacking 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 and the pharmacy'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 stack 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 after each platform's ShopBack-listed voucher; 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 the codes featured on this page and cashback 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. Vitamins earn cashback at the rate on the ShopBack iHerb page.

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; these categories earn cashback at the rate on the ShopBack iHerb page.

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. Beauty earns cashback at the rate on the ShopBack iHerb page; 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. Grocery earns cashback at the rate on the ShopBack iHerb page.

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. Baby items earn cashback at the rate on the ShopBack iHerb page.

Yes, iHerb ships pet probiotics, joint support, calming chews and grooming products to Singapore, and they earn cashback at the rate on the ShopBack iHerb page. 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.

No. The ShopBack iHerb page lists Autoship and Save orders in its Terms and exclusions section. iHerb's subscription (shown as Subscribe and Save on sg.iherb.com) gives a recurring discount in exchange for scheduled deliveries, but those orders do not track. If cashback matters more than the subscription discount, set your own reminder and reorder manually through ShopBack each time with a code featured on this page; if the subscription discount is larger than the cashback at the rate shown, subscribe and skip ShopBack 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. Because ShopBack's iHerb terms exclude any order containing iHerb Rewards or promo codes and any store credit redemption, Rewards and ShopBack do not stack on the same order. You can still earn Rewards credit on an order placed through ShopBack as long as you do not apply credit or a referral code to it; spend the credit later on a separate order. Rates are on the ShopBack iHerb page.

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, so they do not trigger the promo-code exclusion and the order can still earn cashback at the rate on the ShopBack iHerb page. 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.

No. ShopBack's iHerb exclusions name iHerb Rewards and promo codes in the three-letters-plus-numbers referral format, so an order with a referral code applied will be rejected for cashback. If you are new to iHerb, decide which is worth more on your first order: the referral welcome credit, or cashback at the rate shown on the ShopBack iHerb page plus a code featured on this page. On larger first orders the ShopBack route usually comes out ahead; on small ones the referral credit may.

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. Shipping fees are excluded from cashback, which is paid on the product subtotal at the rate on the ShopBack iHerb page.

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. Cashback on eligible orders is at the rate on the ShopBack iHerb page.

Yes. Singapore applies 9% 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 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. ShopBack cashback is calculated on the product subtotal excluding GST, shipping and fees, at the rate on the ShopBack iHerb page.

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. A refunded or returned order loses its ShopBack cashback, which is why confirmation waits until 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. ShopBack Singapore has listed iHerb as a cashback merchant for years; the rate and exclusions are shown on this page.

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), when you can wait a few days, and when you are not planning to spend iHerb Rewards credit on that order. 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, apply IHERB20 or IHERB6 if your spend qualifies, 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), when you want to spend Rewards credit or a referral code (that order cannot earn cashback), 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. Everything else, route through the ShopBack iHerb page.

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 always cheaper: 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 and check the live rate on this page. read more

For most iHerb orders, yes: going through ShopBack 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 in the same session. What comes back is cash, not points or iHerb Rewards credit, so it works like a discount on the order price after you pay. Use only the codes featured on this page, since Rewards credit, referral codes and outside codes stop the order from earning, and check the live rate on this page.
