About iHerb GBP
iHerb discount codes and voucher codes are listed above. What follows: what the site sells, what ordering from it involves for a UK customer, and what an iHerb discount code covers.
About iHerb
iHerb is a large international retailer of vitamins, supplements and natural health and beauty products, carrying well over a thousand brands from a central warehouse operation rather than manufacturing anything itself.
Its appeal in Britain is range and price. A great many American and specialist brands are either unavailable here or sold at a considerable markup, and iHerb is the usual route to them.
What they sell
Vitamins, minerals and herbal supplements, sports nutrition, probiotics and specialist formulations, alongside natural beauty, bath and body, groceries, baby products and household goods.
Own-brand ranges sit next to the named manufacturers, and the site carries an unusually deep back catalogue, including sizes and strengths that do not reach UK shelves.
Ordering from abroad
Understand the import position before the basket, because it is what decides the real price. Orders shipped into the UK from outside can attract VAT and, above a threshold, customs duty and a handling fee. Whether that is collected at checkout or on delivery depends on the order, and the site states which applies.
Supplement rules differ between countries. Doses and ingredients that are ordinary in the United States are sometimes restricted or not permitted here, and a parcel can be held or returned for that reason rather than any fault of the seller.
Check the expiry dates and the pack sizes. Buying a year's supply is where the saving is, and it only works if you will finish it in time.
Nothing sold here is a medicine, whatever a product page implies. They do not treat, prevent or cure anything. If you take prescribed medication, several common supplements interact with it, and a pharmacist will tell you in a minute whether yours does; anyone pregnant, breastfeeding or managing a diagnosis should ask a doctor first.
Using an iHerb discount code
Load the basket, enter the code ahead of the payment step, and read back the final figure with carriage and any import charge included. These appear as iHerb discount codes, voucher codes and promo codes.
Many of the offers here are limited by country or to new customers, and the site runs several at once that will not combine — a first-order code, an autoship reduction and a brand event, where only one applies. Test the total under each rather than assuming they stack.
