How to Use the iHerb Coupon Code
The code box lives on the Cart page, not on Checkout — that’s tripped up plenty of people over the years, so it’s worth calling out directly. Click the shopping cart icon in the top right of iherb.com, find the coupon code field there, and enter TBV598. This code is meant for new customers; if you’ve ordered from iHerb before, it may not apply.
The easiest route is skipping the manual entry entirely: click here (or the image above) and the referral code rides along with you automatically.
One honest note: iHerb frequently runs its own public sitewide promo codes — seasonal sales, category discounts, first-order codes posted on their homepage or social channels — and those sometimes beat what a referral code like ours offers. It’s worth a quick look at iherb.com before you check out, in case there’s a better public deal running right now.

A Few Iherb Staples Worth Checking Out
There’s too much on iHerb to list, but a few categories consistently show up in our own cart: magnesium and calcium supplements, natural soaps, organic olive oil, raw honey, and pantry basics like whole-wheat pasta. The code applies across all of it, so it’s worth browsing broadly rather than sticking to one category.

Once you’ve placed an order, iHerb gives you your own personal referral code to share with friends and family — you’ll find it in your account after your first purchase. Referring friends earns you rewards credit that can be applied to future orders. Exact reward amounts and cash-out terms are set by iHerb and can change, so check your account’s Rewards page for the current numbers rather than relying on any figure we could print here.
What Is iHerb?
iHerb is a global online retailer for supplements, vitamins, herbal products, natural foods, and personal care items, shipping to customers in well over 100 countries. It’s one of the larger players in the space — you’ll usually find the same supplement available across several different brands, so there’s real room for comparison shopping within a single checkout.
iHerb also runs its own loyalty program, iHerb Rewards, separate from referral codes like TBV598. According to iHerb’s own numbers, the program paid out over $98 million in customer credits in 2025 across nearly 4 million reward-funded orders — it’s an active, well-used part of how the site works, not a legacy feature.
Frequently Asked Questions
Where do I enter the iHerb coupon code?
On the Cart page, not Checkout. Click the shopping cart icon at the top of iherb.com to find the code field, or just use our link and skip typing it in.
How much does TBV598 save me?
At last check, referral codes like this one take 10% off iHerb’s own house brands and 5% off everything else. iHerb adjusts promotions fairly often, so treat that as a solid baseline rather than a guarantee.
Does this code work for existing customers?
Referral codes are aimed at new customers. If you’ve ordered from iHerb before, it may not apply — check your account’s Rewards page for offers aimed at returning shoppers instead.
Is there a minimum order size?
Historically no — the code has applied even to small orders, occasionally leaving you paying little beyond shipping. Since iHerb changes cart rules from time to time, confirm the discount actually applied before you pay.
When was this page last checked?
We verified the TBV598 code, the /out/iherb/ link, and iHerb’s Rewards program details directly on iherb.com in July 2026.
