# Buying Protein Powder on iHerb: What You Need to Know

iHerb has become a major player in the supplement space. Their protein powder prices are often lower than Amazon, especially when you factor in their auto-ship discount. Here's what you need to know before buying.

## Why Consider iHerb for Protein Powder?

Most people default to Amazon for supplements. I did too, until I actually compared prices.

- Lower base prices: iHerb is typically $2-5 less than Amazon on the same products
- 10% auto-ship discount: Available immediately, stacks with sale prices
- Wide selection: Major brands plus niche options that Amazon doesn't stock
- International shipping: 150\+ countries
- Reliable stock: No third-party marketplace means fewer counterfeits

## The iHerb Auto-Ship Discount

iHerb's auto-ship program is their standout feature. It works like this:

- Set up recurring delivery every 1, 2, 3, 4, 5, or 6 months
- Get an extra 10% off your order
- The discount stacks with existing sale prices
- Cancel or modify anytime before your next order ships

This is where iHerb wins. Amazon's Subscribe & Save is only available on eligible products, and the discount varies. iHerb gives you the full 10% on day one, on everything.

## Pricing Comparison by Brand

On popular products, iHerb is usually cheaper:

- Optimum Nutrition Gold Standard: $3-5 less than Amazon
- Dymatize ISO 100: $4-6 less than Amazon
- NOW Foods Whey Protein: Often the cheapest option overall

## Things to Watch Out For

### Shipping Costs

iHerb offers free shipping on orders over a certain threshold \(varies by region\). Below that, shipping costs can add up. Always factor shipping into your total cost comparison.

### Import Fees \(International\)

If you're outside the US, some countries charge import duties on supplements. iHerb is upfront about these costs at checkout, but check your local regulations before ordering.

## Frequently Asked Questions

### Is iHerb legitimate?

Yes. iHerb started in 1996 and is now one of the largest online supplement retailers. They buy directly from manufacturers, so everything is sealed and fresh.

### Can you trust the quality?

iHerb sells authentic products from real brands. Amazon's third-party marketplace sometimes has counterfeits; iHerb doesn't have that problem. The protein powder from iHerb is the same product you'd get anywhere else.

### What's the return policy?

You have 60 days to return items. Unopened products get a full refund; opened products might get partial refund or store credit. Contact customer service if something arrives damaged or wrong.

### When are the sales?

iHerb runs sales around New Year's, summer, and Black Friday. They also have brand-specific discounts throughout the year. Sign up for emails if you want notifications.
