Your supplement brand is doing $200,000 a month. Revenue is clean, customers are real, and chargebacks are under 0.7%. But Stripe declined you. Square said no. PayPal terminated you without explanation.
This is the nutraceutical trap. Your business is legitimate—but payment processors see “supplement” or “nutraceutical” and immediately think compliance risk, FDA violations, unsubstantiated health claims, and high chargebacks. The difference between a supplement brand that processes smoothly and one that gets repeatedly declined comes down to understanding why processors are scared of your industry—and proving you’re not the reason they should be.
Why Nutraceuticals Are High-Risk (From a Processor’s Perspective)
FDA and Health Claims
The FDA doesn’t regulate supplements the way it regulates drugs. A drug must prove safety and efficacy before it can be sold. A supplement just has to list ingredients and ensure safe manufacturing. This gap creates compliance risk. If your supplement makes a health claim—“cures arthritis,” “eliminates depression”—the FDA can come after you. And if the processor facilitated those sales, the processor may become liable too.
Most processors don’t have the expertise to distinguish between legitimate and prohibited health claims. So they decline all supplement businesses. The ones who don’t decline often get hit with chargebacks because customers bought expecting clinical results, didn’t get them, and disputed the charge.
High Chargeback Rates
Supplements have a unique chargeback pattern. The product arrives. The customer receives it. But the customer doesn’t get the result they expected. Supplement efficacy varies wildly by person—one customer loses 10 pounds on a fat-burner, another loses nothing. The one who didn’t see results disputes the charge. Dispute rates for supplement subscriptions run 1.5–2.5%, compared to 0.3–0.5% for most ecommerce. That’s 3–5x higher than normal.
Marketing Claims That Look Like Health Claims
Supplement brands often market aggressively: “Transform your body in 30 days.” “Eliminate fatigue forever.” From a processor’s perspective, these can look like prohibited health claims and potential lawsuits. The safer play is to decline.
How to Get Approved: The Nutraceutical-Specific Playbook
Step 1: Separate Health Claims from Marketing Claims
Review your entire website—homepage, product pages, blog, emails, ads. Look for anything that could be interpreted as a health claim.
Prohibited language: Cures, treats, prevents, diagnoses, or mitigates any disease. Also avoid “scientifically proven,” “clinically tested,” “FDA approved.”
Allowed language: Supports, promotes, helps with, encourages. “Supports healthy weight management” is fine. “Cures obesity” is not.
Your underwriter will review this. Prohibited language means decline or mandatory revision before approval.
Step 2: Document Your Compliance
Create a compliance file showing: supplement facts labels, marketing claims (demonstrating they’re compliant), privacy policy and terms of service, customer refund policy, subscription cancellation process, and any third-party testing or certifications (GMP, NSF, etc.). This file is both your processor submission and your insurance that you’re actually compliant.
Step 3: Build a Compelling Chargeback Prevention Strategy
Your biggest liability is chargebacks. Your biggest opportunity is proving you can manage them. Create a chargeback prevention document covering:
- Clear product descriptions with individual results disclaimers on every page
- Easy refund policy: “30-day money-back guarantee. If you’re not satisfied for any reason, we’ll refund within 7 business days.” This massively reduces chargebacks—unhappy customers refund instead of dispute.
- One-click cancellation: No explanation required, no retention email, no friction. Just: “Your subscription has been canceled.”
- Pre-renewal emails with the cancellation link included and a clear statement of what they’re being charged
Chargebacks happen when customers don’t remember signing up or don’t know how to cancel. Remove both friction points and your chargeback ratio drops 30–50%.
Step 4: Document Your Customer Base
Supplement processors want to see real customers with real repeat purchases. Prepare your number of active customers, average customer lifetime value, repeat purchase rate, and customer acquisition source. This shows your business isn’t a flash-in-the-pan marketing stunt.
Step 5: Prepare Your Business and Tax Documents
Standard docs: business license, articles of incorporation, EIN, 6 months of bank statements, last year’s tax return, personal ID for all owners. Supplement-specific: proof of GMP-certified manufacturing, ingredient sourcing documentation, and any third-party testing results.
The Underwriting Conversation
When an underwriter reviews your application, they’re asking three questions: Are you making prohibited health claims? Are your chargebacks manageable? Is this a real business with real customers? Answer those three questions clearly with documentation and you’ve removed the processor’s main concerns.
What to Do if You’re Already Approved But at Risk
Watch for these warning signs: reserve percentage increasing without explanation, audit requests becoming more frequent, settlement times slowing, and chargeback notifications becoming more aggressive. If you see any of these, proactively reach out: “I want to make sure we’re on the same page about compliance. Here’s our updated chargeback prevention strategy. Is there anything else I should address?” Most processors appreciate the transparency.
