iHerb Promo Codes and Discounts for October 2026

A promo code is a short word or a mix of letters and numbers that gives you a discount in the iHerb cart. There are two kinds:

• Promo codes. iHerb releases them for its sales. Each one has an end date, a list of countries and its own conditions: a minimum order, certain brands or categories, new customers only or app only.
• Referral codes. They belong to iHerb customers. A new customer who uses one gets 10% off their first order.

The quickest way to use a code is to click “Apply” next to it in the list above: iHerb opens with the code already in your cart. You can also enter it yourself (see below).

• On banners on the iHerb home page and category pages, and on the Sales & Offers page.
• In iHerb emails and app notifications. Turn them on under Communication Preferences in your account settings. Codes from emails are often personal and work only on the account they were sent to.
• From friends who shop on iHerb: they can share their referral code or link.
• In the list on this page. We collect public codes with their conditions and end dates and check them on iHerb automatically.

Some iHerb links already contain a code: open one and the code is added to your cart.

In the iHerb cart, find the “Apply promo code” field in the Order Summary, enter the code and select “Apply”. You need at least one item in your cart. If the code works, the order total updates right away.

It works the same way in the iHerb app.

In your cart, select “Remove” under the “Apply promo code” field. iHerb confirms that the discount is gone, and you can enter another code.

A referral code can’t be removed, but if you add a promo code with a bigger discount, iHerb uses that one instead.

New customers in many countries get 20% off their first order with NEW20, iHerb’s own welcome code. Other 20% codes come and go: usually for certain brands, sometimes for the whole order. When iHerb launches one, we add it to the list above.

No. iHerb applies one code per order. If you enter several codes, or a referral code and a promo code, iHerb keeps the one with the bigger discount.

Promo codes also don’t combine with other offers, such as specials or trial items: when several discounts could apply, iHerb gives you the biggest one. And even a code for the whole order may not cover some brands, so check the offer terms on iHerb.

Your referral code (iHerb calls it a Rewards code) and your personal link are on the Rewards Overview page in your account. When someone shops with them, you earn Rewards credit: 10% on a new customer’s order and 5% on a returning customer’s. The credit becomes available 35 days after their order.

New customers who use your code get 10% off their first order.
