iHerb is one of the world's largest online retailers of vitamins, supplements, natural beauty products, and health foods — with over 35,000 products from 1,200+ brands shipped to 185 countries. If you spend any money on supplements or natural wellness products, iHerb almost certainly sells them for less than your local health store.
But iHerb is also a platform with multiple discount mechanisms that most shoppers leave money on the table by not using. This guide breaks down every way to save more.
Why Shop on iHerb?
- Prices are typically 20–40% cheaper than UK or Australian health food stores for the same brands.
- Direct relationships with brands means fewer middlemen and lower prices.
- Brand-name products are authentic — iHerb has a strong anti-counterfeit policy.
- 35,000+ products including many not available in your home country.
- Shipping to 185 countries, with fast dispatch and reliable tracking.
The iHerb Rewards Programme
iHerb's loyalty programme gives you 10% back on purchases as iHerb Credit, which can be applied to future orders. This effectively means a 10% perpetual discount if you shop regularly. There is no minimum spend to earn or redeem credits — they apply automatically at checkout.
iHerb Credits expire after 60 days of account inactivity. If you're a periodic shopper, make sure to place a small order within 60 days to keep your credits alive.
Brand Deals: Up to 25% Off Selected Products
iHerb runs rotating 'Brand Deals' where specific product lines are discounted 15–25% for a limited time. These rotate weekly, so if your favourite supplement brand isn't on deal today, check back in a week or two. The deals section on the iHerb homepage is worth bookmarking.
Promo Codes and Discount Codes
iHerb regularly distributes discount codes through affiliate partners and email newsletters — typically 5–15% off your total order. These codes often stack on top of existing sale prices and Brand Deals, which is where the real savings compound.
The most reliable place to find active iHerb promo codes is deal aggregator sites like ours, as we actively maintain and verify codes. iHerb's own newsletter also sends exclusive codes to subscribers.
Bundle Packs Save More Per Unit
Many popular supplements on iHerb are available in bundle packs (e.g., buy 3, get 15% off). For products you use consistently — protein powder, vitamin D, omega-3, etc. — buying in bulk is almost always the smart move. The per-unit savings on bundle packs often exceed the loyalty credit discount.
Best Product Categories to Buy on iHerb
| Category | Typical Saving vs. Local Retail | Top Brands |
|---|---|---|
| Vitamins & minerals | 30–45% | NOW Foods, Solgar, Thorne |
| Protein powders | 20–35% | Optimum Nutrition, Garden of Life |
| Probiotics | 25–40% | Jarrow, Garden of Life, Renew Life |

Shipping Tips
- Most countries have a free shipping threshold — in the UK it's around £35, in Australia it's around A$50. Plan your orders to hit this.
- iHerb ships from US and EU warehouses. Products shipped from their European warehouse arrive faster (2–5 days) for UK and European customers.
- Check customs duty thresholds for your country — for very large orders, duties may apply and reduce your savings.
- iHerb's app often has exclusive app-only deals, so browse on mobile before finalising your cart.
The Stack: Combining All Discounts
The most powerful way to shop iHerb is to stack: start with a brand deal (15–25% off), apply a promo code (5–10% off), and earn 10% credits on the discounted total. On a £100 order, this could look like: £25 brand deal discount + £8 promo code = £67 order, then earn £6.70 in credits for next time. Effectively 33% off on a regular basis.
Final Thoughts
iHerb is genuinely excellent for anyone spending money on supplements, vitamins, or natural health products. The price gap vs. local health food stores is large and consistent. The key to maximising value is using the rewards programme, stacking promo codes with brand deals, and planning orders to hit free shipping thresholds.
