Each iHerb code below is listed for Singapore or for all countries. Tap a code to copy it, then paste it into the Promo code field in your iHerb cart. iHerb accepts one promo code per order, so pick the one that gives the lowest final total in SGD for your basket. The guide under the list explains how to choose.
How to use an iHerb promo code in Singapore
Tap a code to copy it, then add your products on iHerb Singapore and open the cart. Paste the iHerb coupon code into the Promo code field and press Apply: the discount appears in the order summary. When more than one code is eligible, iHerb keeps the one that saves more. Check the final amount in SGD, including shipping, before you pay.
Which iHerb discount code is best for your basket
First price the items you actually need. A code with no minimum spend usually beats a bigger percentage with a threshold when the basket is small. If a code requires a minimum spend, calculate how much more you must add and whether those products are genuinely useful. Test the two strongest codes in the cart and keep the one with the lower delivered total.
iHerb coupon for your first order
New customers get the largest discounts: first-order iHerb coupons are listed separately above. They work only on the first order of a new account. Returning customers should use a code for the whole order instead. The iHerb app voucher applies only when you check out in the iHerb app.
What an iHerb voucher does not cover
Promo codes cannot be combined with Trial items, Super Deals, automatic site promotions or iHerb exclusive brands. Since March 2026 the discount from a single iHerb promo code is capped at US$50 per order. Brand codes, such as those for Doctor's Best or Metagenics, reduce only the price of that brand's products.
Final Singapore checkout check
Confirm that the site is set to Singapore and SGD, the delivery address is correct, and the displayed shipping method suits your order. Check product quantity, best-by date for clearance items, and the final payable amount before placing the order. Health products deserve an extra label and suitability check; a discount is never a reason to buy more than you need.
Work out whether a minimum spend helps
Imagine a basket of US$42 and an iHerb discount code that starts at US$60. Adding a US$18 product to receive 10% off still means paying more than you planned. If the added product was already on next month's list and keeps well, that may be reasonable. If it was chosen only to qualify, the code has increased your spending. Run the same calculation for a free-shipping threshold, using the final checkout totals.
If an iHerb code does not work
Check the code's minimum spend and whether it is for new customers only. Remove Trial items and Super Deals from the cart, because they block promo codes. Make sure the site is set to Singapore: a code issued for another country will be rejected. Codes marked two-time use stop working after the second order on the same account. Then try the next code on the list.
Make repeat orders intentional
For items bought regularly, compare the Subscribe & Save price with a one-off order that uses a promo code before the next shipment is processed. Your use rate may change, and a product that was good value last season may no longer be the right size. If you try a new supplement or skincare item, begin with a sensible quantity and read the ingredient and usage information.
Common questions
Is there a working iHerb promo code for Singapore right now?
Yes. Every code on this page is listed for Singapore or for all countries, and the list is checked regularly. Codes that stop working are removed.
What is the difference between an iHerb coupon, discount code and voucher?
On iHerb they are the same thing: a promo code entered in the Promo code field of the cart. Some codes cover the whole order, others only a first order, the app or one brand.
Can I use two iHerb promo codes on one order?
No. Only one promo code applies per order. If you enter a promo code and a Rewards code, iHerb keeps the one that gives the bigger discount.
Why did my iHerb code not reduce the price?
Check the minimum spend and customer eligibility. Trial items, Super Deals, site promotions and iHerb exclusive brands are excluded, and the discount is capped at US$50 per order.
Should I add an item just to reach the minimum spend?
Only when you would buy the extra item anyway. Compare the final totals with and without it.
Pick the iHerb code that gives the lowest final total in SGD, not the biggest percentage.
