Apply the discount code (step by step)
- Open iherb.com and set your country to the United Kingdom so prices show in pounds and the ยฃ29 delivery threshold applies.
- Fill your basket, then check whether adding one more item takes you past ยฃ29 and removes the ยฃ3.99 delivery fee.
- Go to the checkout and look for the promo code box in the order summary on the right.
- Paste the code exactly as written and apply it, then watch the subtotal update, see the image below if you cannot spot the field.
- If you have Rewards Credits on your account, check whether they have been applied before you pick a payment method.
- Choose Global Air or a paid courier and place the order. Job done!

iHerb statistics
New iHerb codes appear roughly every week. The average iHerb discount is 18%, today's best of 20% holds up well.
Getting the price down at iHerb
The cheapest way to shop iHerb is rarely a one-off code. Standard delivery to the UK, sent as Global Air, is free once your basket passes ยฃ29, and ยฃ3.99 below that, so the first move is usually to top the order up rather than pay postage on a single tub of magnesium. On top of that sits Autoship and Save, the subscription option that discounts repeat orders by up to 10 per cent and ships free on recurring orders over ยฃ30.
What iHerb sells
The catalogue is built around supplements and natural health: vitamins, minerals, protein powders, herbal extracts, probiotics and omega oils, alongside natural beauty, sports nutrition, groceries and baby products. The range leans heavily on American and international brands that UK high street chemists do not stock, which is the main reason people order from here rather than locally.
Standing ways to save
- Free Global Air delivery over ยฃ29, with a ยฃ3.99 flat fee below that threshold.
- Autoship and Save for recurring orders, up to 10 per cent off and free delivery over ยฃ30.
- The Rewards programme, which pays 10 per cent in Rewards Credits when a new customer orders through your Rewards link or code and 5 per cent when an existing customer does.
- App-only promotions on supplements, which run separately from the website offers.
One practical note on the Rewards side: any credit sitting on your account is applied automatically to subscription orders before your chosen payment method, so it is worth checking the balance before assuming a payment amount. Global Air picks the fastest available carrier for you, which in the UK usually means Royal Mail, Evri or Amazon Shipping, and DHL Express and FedEx are offered as paid alternatives. For supplements shipped from within the UK, Raw Powders and Lily and Loaf avoid the wait, and Naturecan covers the CBD side.
