Complete iHerb Guide

The major supplement platform: Now Foods, California Gold, Solgar, discount codes, Subscribe savings, and Taiwan import rules

iHerb is one of the world's largest supplement and natural-products retailers

Founded in 1996, iHerb carries tens of thousands of products and ships to many countries. It can ship directly to Taiwan, but freight can be higher for small orders. This guide explains discount codes, Brand Rewards, personal-use TFDA rules, and practical savings tactics.

Why Use iHerb?

  • Large catalog: supplements, natural foods, personal care, and beauty products
  • Transparent unit pricing: many products show per-serving cost
  • Authenticity control: iHerb sells through its own platform rather than open third-party marketplace listings
  • Direct Taiwan shipping: available for many products with 5 to 10 day delivery windows
  • Chinese interface and Taiwan payment support: easier than many U.S. supplement stores
  • Price gap: often 30% to 50% below Taiwan pharmacy or retail pricing

Discount-code System Explained

Four iHerb Discount Types

Types: discount code / referral code / Brand Rewards / Subscribe

Summary: iHerb discounts can stack in some cases, and strong promotion periods can save 25% to 30% or more.

Four Discount Types

  1. New-customer first-order discount: usually a fixed amount or percentage for the first order
  2. Referral code: the buyer receives a discount and the referrer receives credit
  3. Brand Rewards: credits earned from eligible purchases for later use
  4. Subscribe savings: recurring products can receive an extra discount on scheduled orders

Stacking Examples

  • New customer: new-customer offer + referral code + Brand Rewards credit can create strong first-order savings
  • Promotion season: Brand Rewards + Subscribe + limited-time brand promotions can make larger replenishment orders worthwhile
  • Daily or weekly spotlight: selected brands may receive deeper short-term discounts
Discount-code caution

Some products or brands do not accept discount codes or Brand Rewards. Always verify the final discount in the cart before checkout.

Five Money-saving Tips

1. Combine Subscribe savings with Brand Rewards

Recurring products can receive extra savings, and Brand Rewards credits can reduce future orders. Cancel or adjust subscriptions before the next billing cycle if needed.

2. Use iHerb promotion windows

Weekly spotlight brands, end-of-season sales, Black Friday, and iHerb anniversary promotions can produce the deepest discounts.

3. Consolidate to hit efficient freight thresholds

Combine enough items to spread freight cost, but keep quantities within personal-use and customs-safe ranges.

4. Use referral codes properly

New buyers can use a referral code, then receive their own code for later referrals. Confirm the discount appears before payment.

5. Buy larger bottle sizes when consumption is steady

NOW Foods 250-count bottles or 5 lb protein tubs usually have lower per-serving cost than small sizes. Do not overbuy products with short shelf life.

Seven iHerb Consolidation Steps

1List your supplement needs

Write down monthly-use supplements, estimate a reasonable six-month household quantity, and set a budget before shopping.

2Choose iHerb and apply discounts

Use iHerb.com, apply a valid referral or new-customer code, and confirm Brand Rewards or subscription discounts.

3Choose direct shipping or consolidation

Use direct shipping for small trial orders. Use consolidation for larger multi-item purchases, repeat orders, or combined Amazon U.S. purchases.

4Use the Oregon warehouse for consolidation

Ship U.S. orders to the Oregon warehouse and combine with Amazon U.S., Costco, GNC, or other items where appropriate.

5Inspect after warehouse arrival

Confirm product names, quantities, and expiration dates. Check again for TFDA-restricted ingredients such as hormones or CBD.

6Complete EZWay declaration

Declare as supplements or food with accurate value and personal-use quantity. See the supplement import guide for details.

7Clear customs and deliver

Duty can vary by classification, and 5% business tax may apply. Food and supplement inspection risk depends on ingredient and quantity.

iHerb FAQ

Q1. Is iHerb direct shipping to Taiwan cheap?
It depends on order value. Small orders can lose their price advantage because freight is too high. Larger orders that qualify for direct-shipping promotions can still be cheaper than Taiwan retail. For multi-store or repeat orders, U.S. consolidation may produce better freight efficiency.
Q2. How do I use iHerb discount codes effectively?
Stack eligible discounts where possible: new-customer offers, referral codes, Brand Rewards, Subscribe savings, and limited-time brand promotions. Some products are excluded, so check the cart total before payment.
Q3. Can I import melatonin from iHerb?
Melatonin is treated as a prescription medicine in Taiwan, so it is high risk. Small personal-use quantities may sometimes pass, but the safer recommendation is to avoid importing it unless you have proper medical and import documentation.
Q4. Can I import a 5 lb tub of protein powder?
Yes, but protein powder is generally treated as food rather than a bottled supplement. Keep the quantity reasonable for personal use, watch the total food weight allowance, and avoid formulas containing prohibited stimulant or steroid-like ingredients.
Q5. iHerb vs. Amazon U.S. vs. Costco: which is cheaper?
iHerb is best for broad specialty supplement selection and premium brands. Amazon U.S. can win during Prime Day or Subscribe & Save promotions. Costco U.S. is strongest for large-format value items such as Kirkland fish oil and CoQ10. Compare per-serving cost and shipping together.
Q6. Do iHerb shipments to Taiwan require tax?
Tax depends on value and product classification. Direct shipments may include some customs handling in the checkout flow. Consolidated shipments are declared through the forwarding route, with duty and 5% business tax calculated when applicable. Declare honestly and avoid commercial-looking quantities.
