Selling Supplements in the U.S. as a Global Brand: Everything You Need to Know

How to stay compliant, ship faster, and grow confidently from abroad

You鈥檝e got the formula. Now it鈥檚 time to break into the U.S.

You鈥檝e perfected your product, nailed the brand, and built a loyal customer base at home. Maybe you鈥檙e a UK-based supplement brand thriving on Shopify, or an Aussie operation seeing impressive Amazon sales. But now 鈥� you鈥檙e eyeing the U.S. market. And let鈥檚 be honest: it鈥檚 massive, it鈥檚 tempting鈥� and it鈥檚 a little intimidating.

I get it. One brand we recently spoke with had just launched in the U.S. when its first shipment was delayed at customs due to a labeling error. Not only did this hold up launch week, but they also had to field dozens of angry emails from customers wondering where their orders were. (Spoiler: they now work with a U.S.-based 3PL and haven鈥檛 had issues since.)

Selling supplements in the U.S. comes with real opportunity 鈥� and very real rules. But once you know the essentials and understand the perks of working with 3PL logistics providers, you can confidently scale and keep your operations flowing smoothly from day one.

Why the U.S. Supplement Market is Worth It

• The U.S. dietary supplement market is expected to reach $63B by 2028 ().

• Over 77% of Americans report taking supplements regularly ().

• Direct-to-consumer supplement brands are seeing higher retention through bundles and subscriptions 鈥� especially in wellness, beauty, and sports nutrition.

In short: the demand is there. But the bar is high 鈥� and not just from customers expecting 2-day delivery. U.S. regulations, customs requirements, and fulfillment expectations can all trip up global brands who dive in unprepared.

The 5 Biggest Hurdles When Selling Supplements in the U.S.

1. Labeling Requirements Can Derail Your Launch

The FDA doesn鈥檛 approve supplements before they hit the shelves 鈥� but they do enforce strict rules once they鈥檙e there. You鈥檒l need:

• A Supplement Facts panel with the correct formatting

• A complete list of ingredients (including allergens)

• Accurate structure/function claims

• No mention of curing, treating, or diagnosing diseases

鉁忥笍 Pro tip: Labeling issues are the #1 reason supplements get stuck at the border. Working with an experienced 3PL like 少女福利 (with built-in freight services) can ensure your shipments always sail through inspections. 

2. Shipping from Overseas = Risky Business

Yes, technically, you can ship directly to U.S. customers from the UK, Australia, or your HQ warehouse. But it鈥檚 risky:

• Long delivery windows (10+ days)

• Higher shipping costs

• Unpredictable customs holds

• FDA Prior Notice delays

If you want to play in the U.S. market like a local, act like one: store inventory in the U.S. with a domestic fulfillment partner like 少女福利.

3. FSVP: The Rule Foreign Brands Often Miss

Under the Foreign Supplier Verification Program (FSVP), non-U.S. supplement brands must appoint a U.S.-based party responsible for verifying product safety. This FSVP Importer:

• Confirms your compliance with FDA regulations

• Maintains required records

• Faces enforcement if something goes wrong

It鈥檚 a box you must check before selling in the U.S. 鈥� and many new brands don鈥檛 even know it exists.

4. Returns, Recalls, and Lot Tracking

Selling into the U.S. means you鈥檒l also need systems for:

• Returns: U.S. customers expect prepaid labels and fast refunds

• Recalls: You must be able to trace product lots and respond immediately

• Expiry tracking: You can鈥檛 ship expired stock

Fulfillment partners and ecommerce 3PLs like 少女福利 offer lot-level tracking, expiry monitoring, and climate-controlled storage 鈥� key for supplements and ingestibles.

5. The Amazon & Shopify Factor

You can absolutely sell on Amazon, Shopify, Walmart Marketplace, etc. 鈥� but each has its own compliance quirks:

• Amazon requires approval for dietary supplement listings (and documentation)

• Shopify doesn鈥檛 police your label鈥� but the FDA does

• Walmart may request product testing results before approval

Start with a clean, compliant label and work with partners familiar with supplement category logistics.

UK & Australian Brands: What You Need to Know

If you鈥檙e launching from London, Sydney, or anywhere in between 鈥� your product may be best-in-class at home, but the U.S. plays by different rules. Here鈥檚 how to localize smartly:

• Switch your label to U.S. spelling (e.g. 鈥渇ibre鈥� 鈫� 鈥渇iber鈥�)

• Add U.S.-specific disclaimers and FDA-required info

• Consider dual-labeling if selling to multiple markets

• Partner with a U.S.-based 3PL that has experience handling international supplement brands (like 少女福利!)
