If you want to know how to start a supplement business, the short answer is this: pick a narrow product idea, form the company, choose a manufacturer that follows FDA manufacturing rules, get your label and claims right, and set up payments that can handle a higher-risk product. Most new brands get the product side mostly right. They stumble on claims and payments, which is where launches stall.
This guide walks through each step in order, with a focus on the parts manufacturer guides usually skip: what card processors look at before they approve a supplement store, and how to build your website so it passes that review the first time.
Key takeaways
- FDA does not review supplements before they go on sale. Your company is responsible for the safety and labeling of what you sell.
- Any structure/function claim needs the FDA disclaimer and a notice to FDA within 30 days of first marketing.
- The FTC expects health claims to be backed by solid human clinical evidence, and testimonials don’t replace it.
- Payment processors treat supplements as higher risk. Plan for a full underwriting review, a possible reserve and close chargeback monitoring.
- Clean claims, clear subscription terms and a complete website make approval faster.
Step 1: Choose a focused product and customer
The brands that last usually start narrow. “Wellness gummies for everyone” is hard to market and hard to explain to an underwriter. “Unflavored creatine for women who lift” or “magnesium sleep blend for shift workers” gives you a clear customer, a clear ad message and a product catalog that is easy to review.
Before you order inventory, write down three things: who buys it, why they buy it from you instead of a big brand, and what you will say about it. That last point matters more than most founders expect. The words you plan to use in ads decide how much compliance work and payment scrutiny you will face later.
Some ingredients and product types draw extra attention from card networks and banks. Weight-loss, “testosterone” or sexual-enhancement positioning, and anything sold with free-trial offers are reviewed much more closely than a basic vitamin or protein line. If your idea sits in one of those areas, budget extra time for approval.
State law can add another layer. New York’s General Business Law section 391-oo bars selling weight-loss and muscle-building supplements to anyone under 18, and online sellers must ship those products with a delivery method that requires an adult signature and photo ID. If that is your niche, plan the age check and shipping cost before you set prices.
Step 2: Form the company and set up the basics
Form an LLC or corporation in your state so the business is separate from you personally. Then get an EIN. The IRS lets U.S.-based businesses apply for an EIN online for free, so never pay a third party for one.
Next, open a business bank account in the company’s name and keep every sale and expense in it. Underwriters will ask for business bank statements, and a clean account with no mixed personal spending makes your file much easier to approve. Get product liability insurance before you sell your first bottle. Many manufacturers and retailers also ask for proof of it.
- Register the LLC or corporation with your state.
- Get an EIN from the IRS.
- Open a business checking account in the company name.
- Buy product liability insurance.
- Check your state and city for any business license or sales tax registration you need.

Step 3: Pick a manufacturer that follows cGMP
Most new brands don’t build a factory. They work with a contract or private-label manufacturer. Whichever route you take, the manufacturer has to follow FDA’s current good manufacturing practice rules for dietary supplements (21 CFR Part 111). That rule covers anyone who manufactures, packages, labels or holds a dietary supplement, so it can apply to your company too if you do any of that work yourself.
When you compare manufacturers, ask for these before you sign:
- A certificate of analysis for each batch, showing identity, purity and strength testing.
- Their most recent third-party audit or inspection results.
- Minimum order quantities and lead times for your first run and reorders.
- Who owns the formula, and whether you can move production later.
- Whether they help with label review, or leave that entirely to you.
Keep these documents in one folder. Payment underwriters reviewing a nutraceutical merchant account often ask who makes the product and how quality is checked, and a ready answer shortens the review.
Step 4: Get your label and claims right
This is the step that decides how smooth everything else will be. FDA states that supplement firms are responsible for evaluating the safety and labeling of their products before marketing. There is no FDA approval stamp to lean on. FDA can take action against products that are adulterated or misbranded once they are on the market.
Structure/function claims
A structure/function claim describes how an ingredient supports normal body function, such as “supports restful sleep.” Under 21 CFR 101.93, you must notify FDA no later than 30 days after you first market a supplement with such a claim. The label must also carry this disclaimer: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
Claims that a product treats, cures or prevents a disease are drug claims, not supplement claims. They are also the fastest way to get a merchant application declined.
Advertising and testimonials
The FTC regulates what you say in ads, on social media and on your website. Its Health Products Compliance Guidance says health benefit claims generally need support from randomized, controlled human clinical testing. You are responsible for what your ads imply, not only what they state. Customer testimonials don’t count as proof, and any paid or gifted endorsement has to be clearly disclosed.
| Claim type | Example | What it means for you |
|---|---|---|
| Structure/function | “Supports healthy joints” | Allowed with substantiation, the FDA disclaimer and a 30-day notice to FDA |
| Disease claim | “Relieves arthritis pain” | Treated as a drug claim. Don’t use it on a supplement |
| Testimonial | “I lost 20 pounds in a month” | Implies typical results. Needs real evidence, and paid endorsements must be disclosed |
| Before-and-after photos | Side-by-side body images | Strong red flag for underwriters and ad platforms. Avoid at launch |
Step 5: Build a store that passes payment review
Card processors classify supplements as higher risk because the category has historically had more chargebacks, more subscription complaints and more claims problems than most retail. That doesn’t mean you can’t get approved. It means an underwriter will read your website line by line before they say yes. We cover the full process in our guide to getting a merchant account for a supplement business, but here is what to have live before you apply.
- Product pages with ingredient lists, the Supplement Facts panel and the FDA disclaimer wherever you make a structure/function claim.
- Clear pricing, including shipping and any subscription price, shown before checkout.
- Refund and return policy that is easy to find and easy to follow.
- Shipping policy with realistic delivery times and tracking.
- Terms of service and privacy policy.
- Real contact details: a business address, phone number and support email.
Decide where you will sell first
Your sales channel shapes your payment setup. On a marketplace, the marketplace runs the card payment and you live by its category rules. On your own store, you need your own merchant account and gateway, and an underwriter reviews your site. Wholesale to gyms or clinics usually runs on invoices instead. Most new brands launch on one channel, often their own site, and add others once reorders are steady.
If you sell on a hosted platform, check its own rules for supplements first. Some platforms’ built-in payment tools restrict certain supplement types. Our post on using a high-risk merchant account with Shopify explains how a dedicated account and gateway fit in.
Step 6: Set up payment processing for a supplement brand
A supplement store usually needs three pieces: a merchant account from a bank that accepts the category, a payment gateway that connects your checkout to that account, and tools to manage disputes. Many founders start on an all-in-one payment app and get shut down once sales pick up, because the app’s terms exclude their product. Applying for the right account at the start avoids frozen funds later.
Expect the underwriter to ask for:
- Your business formation documents and EIN.
- A government-issued ID for each owner.
- Recent business bank statements, and processing statements if you already sell.
- Product details and your manufacturer’s certificates of analysis.
- Your website URL with all policies live.
- Your expected monthly volume, average order size and subscription plans.
Our merchant account approval checklist lists every document in one place. Some approvals come with a rolling reserve, where a small share of each sale is held for a set period. That is common for new supplement brands with no processing history, and it usually comes down as you build a clean record.
Subscriptions and auto-ship
Auto-ship is great for repeat revenue, and it is also the most common source of supplement chargebacks. Section 4 of the Restore Online Shoppers’ Confidence Act (15 U.S.C. 8403) requires online sellers that use a negative option, such as auto-ship, to clearly disclose all material terms before collecting billing information, get the customer’s express informed consent before charging, and offer a simple way to stop recurring charges.Show the renewal price and schedule next to the buy button, send a reminder before each renewal and make cancelling simple. Our subscription billing risk checklist covers the details.
Step 7: Launch and keep chargebacks low
Card networks watch each merchant’s dispute rate, and going over their limits can lead to fines or a closed account. For a new supplement brand, the first 90 days set the tone. A few habits make a big difference:
- Use a billing descriptor customers will recognize on their card statement.
- Ship with tracking and send the tracking link right away.
- Answer support emails within one business day.
- Refund unhappy customers quickly instead of letting them call their bank.
- Review every chargeback reason code each week and fix the cause.
Our chargeback prevention guide goes deeper on dispute tools and response templates. If you also sell wholesale to gyms, clinics or retailers, adding ACH payment processing for B2B invoices can cut card fees on large orders.
How to start a supplement business: quick launch checklist
- ☐ Product idea and target customer written down
- ☐ LLC or corporation formed, EIN issued, business bank account open
- ☐ Product liability insurance in place
- ☐ cGMP-compliant manufacturer signed, certificates of analysis on file
- ☐ Labels reviewed, FDA disclaimer added to any structure/function claim
- ☐ Structure/function notice sent to FDA within 30 days of first sale
- ☐ Ads and testimonials checked against FTC guidance
- ☐ Website live with pricing, refund, shipping, terms, privacy and contact pages
- ☐ Merchant account and gateway approved for supplements

Common mistakes new supplement brands make
- Writing ads before checking claims. Re-shooting a campaign is cheaper than losing a merchant account.
- Launching with free-trial offers. They draw some of the closest scrutiny in payments. Start with straightforward pricing.
- Hiding subscription terms. Unclear auto-ship terms lead straight to disputes.
- Relying on a payment app whose terms exclude supplements. Read the terms or apply for a dedicated account.
- Applying before the website is finished. Missing policies or “coming soon” pages slow approval.

FAQ
How much does it cost to start a supplement company?
It depends mostly on your manufacturer’s minimum order, your packaging and your marketing budget. Company formation and an EIN are low cost, while the first production run and launch advertising are usually the largest expenses. Ask several manufacturers for quotes at your target order size before you set a budget.
Do I need FDA approval to sell supplements?
No. FDA does not approve supplements before they are sold. Your company is responsible for safety and accurate labeling, and some steps still apply, such as notifying FDA within 30 days when you use a structure/function claim.
Can I start a supplement business from home?
Yes, many brands run from home by using a contract manufacturer and a fulfillment partner. If you package, label or store products yourself, FDA’s manufacturing rules can apply to that work, so most home-based brands leave those steps to a compliant partner.
Why do payment processors treat supplements as high risk?
The category has a history of chargebacks, subscription complaints and misleading claims. Processors respond by reviewing websites closely and sometimes holding a reserve. A brand with clean claims, clear policies and simple subscription terms can still get approved.
When should I apply for a merchant account?
Apply once your website, product pages and policies are live, but before you start paid ads. That gives the underwriter everything they need and keeps you from building sales on a payment app that may later close your account.
