iHerb offers several ways to save on vitamins, supplements and wellness products. The lead offer is the 22% Off Immunity Support discount code, which is perfect if you are buying products to boost your immune health. This code cannot be combined with other offers, so you will need to choose your single best option at checkout.
For new customers on a first order: If you are shopping at iHerb for the first time, you have two first order options. The 20% Off Your First Order code gives you a solid saving on your initial purchase. However, if you are buying a larger first basket, compare this against the general 22% Off Immunity Support code to see which works better for your items. Neither can be stacked with other offers.
When buying supplements that experts take daily: The 20% off supplements experts take every day discount code, valid until 9 November, applies to general vitamins and minerals as well as formulas for joint support, immune health and athletic performance. On a €60 order of qualifying supplements, for example, you would save €12 and pay €48. This is worth checking if your cart focuses on these types of products.
For a basket over €51: The 10% Off Orders Over €51 code becomes available once you hit this threshold. On a €80 order, you would save €8, paying €72. Below €51, this code does not apply and you should look at the 15% or 22% codes instead.
For a larger basket over €71.68: The 10% Off Orders Over €71.68 code applies to orders at or above this minimum spend. On a €100 order, you would save €10, bringing your total to €90. Again, check this against the other percentage codes to see which leaves you paying less.
When shopping via the app: If you are a new iHerb app user, the 15% Off Your First App Order code gives you a saving across vitamins, supplements, bath and beauty, sports nutrition, grocery, baby and pet products. On a first app order of €70, you would save €10.50 and pay €59.50. There is also a 20% off supplements code for app purchases, valid until 3 November, which applies to the same range of products. On a €70 app order, this would save you €14 and cost €56. For your first app purchase, the 20% code is your better option if it applies to your items.
When browsing sale items: iHerb also runs automatic sales like Up to 60% Off Best-Selling Products, which apply without a code. These cannot be combined with discount codes. Check the final price after the sale markdown and compare it to what you would pay using a percentage off code on the full price to see which is lower.
For free delivery: Regardless of which offer you use, you will get Free Delivery on Orders Over €35 to the Republic of Ireland.
Our records show that iHerb listed 31 offers on our page in the 12 months to October 2026, including 23 codes. The biggest percentage code in that time was 30% off in September 2026, whilst a typical code offered 20% off. Our team tested 11 codes at checkout across 10 offers during this period. iHerb recently ran a 30% off code in September 2026 as part of its anniversary event, which beat every live offer, so it is worth checking back here or signing up to the Love Vouchers newsletter for when a stronger code returns.
Most iHerb discount codes and automatic sales cannot be combined with each other. Calculate the final price for each code that applies to your basket and items, then use whichever one leaves you with the lowest amount to pay.
