iHerb

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 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 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 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 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 the iHerb page above, then click through to iherb.com and check the current cashback rate in the rate table above.

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.

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 ships direct to Singapore from US warehouses with multiple carrier options at checkout, and delivery timing varies by carrier selection and order weight. Free shipping thresholds vary by carrier and order weight, so the current qualifying minimum is best confirmed at iHerb checkout. 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.

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.

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 current cashback rate is published in the rate table on the ShopBack iHerb page above, with upsized windows shown when active.

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 typically shows as pending in your ShopBack account within 48 hours of the transaction, then moves to confirmed after iHerb's return and validation window, usually within 60 to 90 days. Track status under the Orders tab in the ShopBack app or web account.
