If you’re planning to launch a supplement brand, you’re stepping into one of the most profitable markets in the world — but also one of the most regulated.
The global supplement industry is projected to surpass $350 billion by 2028 (source: Fortune Business Insights), and every major manufacturer and brand owner plays by one essential rule: compliance.
Getting your licenses right from the start can mean the difference between building a lasting brand or facing FDA warnings, state fines, or even a shutdown.
Here’s everything you need to know about what licenses and certifications you need to legally sell supplements in the U.S. — plus what to consider if you plan to expand internationally or use AI tools in your operations.
1. FDA Compliance and GMP Regulations
Let’s clear up one of the biggest misconceptions: the FDA does not “approve” dietary supplements before they go to market. Instead, the Food and Drug Administration (FDA) monitors them after launch for safety, labeling accuracy, and compliance with manufacturing practices.
If you’re manufacturing supplements (even through a contract manufacturer), you must comply with the FDA’s Good Manufacturing Practices (GMPs) under 21 CFR Part 111. These rules cover everything from ingredient sourcing and quality testing to packaging and labeling.
What this means for your business:
- Your products must be made in an FDA-registered, GMP-certified facility.
- Every batch must be traceable and tested for purity and potency.
- Labels must comply with FDA structure-function claim rules — meaning you can’t make disease treatment or cure claims.
Key takeaway: You don’t need a “license” from the FDA, but you do need to follow FDA laws and be inspection-ready at any time.

2. State Business License (LLC or Corporation)
No matter how small your operation, you’ll need a general business license in your state.
Register your business as an LLC or corporation to legally operate, collect revenue, and pay taxes. This also gives you liability protection — a must in the supplement industry.
Where to apply:
Visit your state’s Department of State or Secretary of State website. Most applications take under 15 minutes and cost between $50–$300.
Pro tip: Registering as an LLC also helps build brand legitimacy for future partnerships, distributors, or investors.
3. Health Department Permits (If You Manufacture In-House)
If you plan to manufacture or package supplements yourself, your facility will likely need approval from your local health department.
Health departments inspect your workspace to ensure it meets sanitation, temperature control, and contamination prevention standards — especially if you’re handling powders, liquids, or food-grade materials.
If you use a GMP-certified contract manufacturer, this requirement usually falls on them, not you.
Key takeaway:
Check with your county or city health department before producing or packaging any supplement in-house.
4. Seller’s Permit or Reseller’s Permit
If you’re selling directly to consumers (online or in-store), most states require a seller’s permit so you can collect and remit sales tax.
If you’re buying wholesale supplements to resell, you’ll also need a reseller’s permit, which allows you to purchase products tax-free from suppliers.
Example:
- Seller’s permit: You sell your supplement line online and collect sales tax from U.S. customers.
- Reseller’s permit: You buy products from another manufacturer and resell them under your own label.
Where to apply:
Your state’s Department of Revenue website.

5. Trademark and Brand Protection
While not technically a “license,” a trademark is one of the smartest legal steps you can take as a supplement entrepreneur.
Trademarking your brand name, logo, and key product names protects you from copycats and counterfeiters — a growing problem in the wellness industry.
How to apply:
File through the U.S. Patent and Trademark Office (USPTO).
Bonus tip: Many supplement founders skip this step early on, only to face brand conflicts when scaling. File it once, and your brand stays legally protected nationwide.
6. International Sales and Export Regulations
Planning to sell globally? You’ll need to adapt your packaging, formulation, and claims to meet each country’s rules.
Here’s a quick breakdown:
- European Union: Supplements are regulated as food products, requiring precise labeling and ingredient limits (source).
- Canada: Products must comply with Natural Health Products (NHP) regulations and obtain a product license (source).
- Australia: Supplements are considered complementary medicines under the Therapeutic Goods Administration (TGA) and may require pre-market approval.
Key takeaway:
If you sell internationally, hire a compliance consultant familiar with that region’s food and drug laws.
7. AI and Regulatory Automation Tools (New 2026 Trend)
AI is changing how supplement companies handle compliance and operations.
From automated label audits to AI-driven GMP documentation, digital tools are helping supplement businesses stay compliant faster and with fewer errors.
Popular tools include:
- RegASK (regask.com) – AI compliance tool for tracking regulatory changes worldwide.
- FoodChain ID AI (foodchainid.com) – automates ingredient documentation and GMP records for supplement manufacturers.
Why it matters:
AI can help startups scale safely without missing compliance deadlines or manual updates — saving both time and costly penalties.

No. The FDA doesn’t issue a license, but you must comply with 21 CFR Part 111 GMP standards and FDA labeling rules.

Yes, if you use a third-party GMP-certified manufacturer. You’ll still need a general business license and possibly a seller’s permit depending on your state.
Q: What are the FDA label requirements?
Every label must include:

- A disclaimer if you make structure-function claims (“This statement has not been evaluated by the FDA…”)
