Supplement companies don’t usually lose their merchant accounts because the whole business is a problem. They lose them over one ingredient in one product, one claim on one landing page, or one trial offer that drove too many disputes.
The Merchant Guru places supplement and nutraceutical brands with acquiring banks that understand them, and reviews your products, claims, and offers before underwriting does, so the issues that shut accounts down get fixed first.
No hidden fees. No long-term contracts. Just a straight read on your supplement processing options.

It’s one of the most common calls we get from supplement brands. Don’t wait on the form. Call us and we’ll walk through what triggered it and what your options are.
Supplements are legal, popular, and profitable. Processors still treat them as high risk for four reasons:
One overpromising claim can draw FDA or FTC attention, and the bank processing the sale shares that exposure.
Some ingredients sold as supplements are unlawful, unapproved drugs, or controlled substances.
Free trial and auto-ship programs drive the disputes card brands monitor most closely.
“It didn’t work” is one of the most common reasons supplement customers dispute a charge.
The good news: supplement brands with clean ingredient lists, compliant claims, and clear offers are very placeable. Most of what gets a supplement account shut down can be fixed before you ever apply.
Acquiring banks and their monitoring vendors regularly scan merchant websites, marketplace listings, and product labels. With many processors, one flagged ingredient in one product can freeze payouts or close an account, often with no warning at all. We built our process to keep that from happening to you.
We Reach Out
We tell you which product was flagged and why, before anything gets shut off.
You Choose the Fix
Pull the SKU, update the label or listing, or reformulate. You decide what works for your business.
We Work With the Bank
We document the change and walk the acquirer through it, so the issue is closed out properly.
You Keep Processing
The rest of your catalog keeps selling while the one product gets sorted out.
What we catch upfront: a brand with 40 clean products plans to add a pre-workout from a new contract manufacturer. The label lists DMHA, an ingredient the FDA has called adulterated in supplements. We flag it during underwriting, before it ever goes live, so the rest of the catalog is never put at risk.
Proprietary blends make this harder. If an underwriter can’t see what’s in a blend, they assume the worst. Full ingredient disclosure on your labels and product pages helps your file.
This isn’t a complete list, and acquirer policies vary. But these are the ingredients that most often stall supplement applications or trigger account reviews.
| Ingredient | Why It’s Flagged | Processor View |
|---|---|---|
| DMAA | The FDA does not consider it a lawful dietary ingredient | Usually declined |
| DMHA | FDA warning letters in 2019 called supplements containing it adulterated | Usually declined |
| Sildenafil & tadalafil (Viagra, Cialis) | Prescription drugs, not supplements. The FDA regularly finds them hidden in “male enhancement” products. Sold with a valid prescription through a licensed telehealth or pharmacy model, they can be placed. See telemedicine merchant accounts | Separate category |
| Testosterone & TRT | A prescription-only controlled substance, never a supplement. Doctor-prescribed TRT programs are underwritten as telehealth. See telemedicine merchant accounts | Separate category |
| Tianeptine | An unapproved drug the FDA has repeatedly warned consumers about | Usually declined |
| SARMs | Unapproved drugs, not supplements, even when sold as “research chemicals” | Usually declined |
| Ephedra (ephedrine alkaloids) | Banned from supplements by the FDA in 2004 | Usually declined |
| 7-OH (7-hydroxymitragynine) | The FDA recommended scheduling in 2025, and the DEA announced plans to temporarily place it in Schedule I in July 2026 | Usually declined |
| Kratom & kava | Legal federally but restricted in some states. See kratom and kava merchant accounts | Separate category |
| CBD | The FDA says it can’t be sold as a dietary supplement. See CBD merchant accounts | Separate category |
| High-stimulant fat burners & yohimbe | Safety warnings and aggressive weight loss marketing | Case by case |
| Nootropic stacks | Depends entirely on the ingredient list | Case by case |
One processor’s “no” can be another processor’s “yes.” Each acquiring bank decides which ingredients and products it will accept, and they don’t all use the same rulebook.
Some acquirers use LegitScript’s product and ingredient data as their baseline.
Others build their own risk lists or use a different monitoring vendor.
Let us look first. Send us your product list and we’ll go through it SKU by SKU, flag any ingredients or products that might be difficult to place, and match you with the processors most likely to accept your full catalog, before anything is submitted.
Regulatory status changes. This is general information, not legal advice. Confirm your formulations with qualified regulatory counsel.
Under the Dietary Supplement Health and Education Act (DSHEA), supplements can make structure/function claims but not disease claims. The FTC adds its own rule on top: every claim needs competent and reliable scientific evidence behind it.
| Generally Allowed | Higher Risk | Not Allowed for Supplements |
|---|---|---|
| “Supports healthy joints” | “Clinically proven to boost testosterone 300%” | “Relieves arthritis pain” |
| “Helps maintain energy levels” | “Lose 30 pounds in 30 days” | “Treats ADHD” |
| “Supports immune function” | “Doctor recommended” without proof | “Prevents colds and flu” |
| “Promotes restful sleep” | Before-and-after photos with atypical results | “Lowers blood pressure” |
Why your processor cares: underwriters read your website the way a regulator would. Disease claims are one of the top reasons supplement applications are declined. We flag risky language before your file goes in.
Your merchant account is responsible for every page that sells your product, not just your own website. Underwriters and monitoring vendors look at:
Running free trials or auto-ship? Those come with their own Visa and Mastercard rules. See our continuity and negative option billing page.
Here’s how the most common supplement disputes map to Visa dispute conditions.
| Visa Condition | Typical Supplement Trigger | How to Prevent It |
|---|---|---|
| 13.3 Not as Described | “It didn’t work” or the results didn’t match the ad | Realistic claims, accurate ads, and a clear refund policy |
| 13.2 Cancelled Recurring | Auto-ship kept billing after the customer thought they cancelled | Easy online cancellation and confirmation emails |
| 13.5 Misrepresentation | “I didn’t know it was a subscription” | Clear trial terms, separate consent, and 7-day reminders |
| 10.4 Card-Absent Fraud | Stolen cards on low-cost trial offers | AVS, CVV, 3D Secure, and velocity limits |
| 13.1 Not Received | Lost or delayed shipments | Tracking numbers and delivery confirmation |

Selling on subscription? Many supplement brands can now offer recurring Apple Pay and Google Pay billing, set up so renewals keep working when customers change phones.
Supplement files are won on preparation. Here’s what acquiring banks may ask for.
Each category gets reviewed a little differently. Here’s what acquirers focus on.
Protein, pre-workouts, and recovery products.
Underwriters look at: stimulant ingredients and performance claims.
Fat burners, appetite support, and meal replacements.
Underwriters look at: weight loss claims, before-and-after photos, and trial offers.
Daily vitamins, minerals, and general wellness.
Underwriters look at: immune and health claims, and subscription terms.
Focus, sleep, and stress support.
Underwriters look at: every ingredient in the stack, and mental health claims.
Products made by contract manufacturers.
Underwriters look at: manufacturer quality, label accuracy, and COAs.
B2B distribution and multichannel sellers.
Underwriters look at: reseller listings and invoice sizes. Large invoices may fit eCheck and ACH.
Have these ready and most supplement files move quickly:
Things that help: full ingredient disclosure, compliant claims, third-party testing, and clear refund terms.
Things that raise flags: watch-list ingredients, disease claims, hidden trial terms, and unreviewed affiliate pages.

The supplement brands I talk to are almost never trying to cut corners. They added a product their manufacturer recommended, or an affiliate wrote a landing page they never saw, and suddenly their whole account was frozen.
That’s why I start with your product list and your website, not just your application. Fixing one ingredient or one claim up front is a lot easier than recovering from a shutdown.
If you want a straight read on your setup, even if the answer is “you’re fine where you are,” give me a call.

Health claims, regulated ingredients, free trial and auto-ship offers, and high refund and dispute rates all add risk for the bank.
Yes. Banks and monitoring vendors scan your website and listings. If one product contains a flagged ingredient or makes a disease claim, the bank can hold funds or close the entire account, not just that product.
Common ones include DMAA, DMHA, tianeptine, SARMs, ephedra, and 7-OH. Kratom and CBD are usually handled as separate categories. Prescription products like sildenafil, tadalafil, and testosterone can’t be sold as supplements, but doctor-prescribed telehealth programs can be placed. Acquirer policies vary, so we review your full ingredient list before you apply.
No. Some processors use LegitScript’s product and ingredient data as their baseline, while others use their own internal risk lists or a different monitoring vendor. A product one bank declines may be accepted by another. We review your product list SKU by SKU and match you with processors most likely to accept your full catalog.
Yes, when it’s prescribed by a licensed provider. Sildenafil, tadalafil, and testosterone are prescription drugs, so they can’t be sold as supplements. Telehealth and pharmacy businesses that sell them with a valid prescription are underwritten differently. See our telemedicine merchant accounts page for details.
A structure/function claim describes how a product supports the body, like “supports healthy joints.” A disease claim says it treats, cures, or prevents a condition, like “relieves arthritis pain.” Supplements can make the first kind with the FDA disclaimer, but not the second.
Yes. The FTC requires competent and reliable scientific evidence for health claims, and claims to treat serious diseases need randomized, controlled clinical trials. Unsupported claims are a top reason supplement applications are declined.
Yes, with the right setup. Trials and auto-ship carry extra Visa and Mastercard rules, including checkout disclosures and reminders. See our continuity and negative option billing page for details.
Some supplement brands start there, but aggregators often restrict certain ingredients, claims, and trial offers, and accounts can be frozen without warning. A dedicated supplement merchant account is underwritten for your products from the start.
Many are coded 5499, miscellaneous food stores. Continuity offers may use 5968. Some acquirers use other codes depending on the products, so we confirm the right fit for your account.
Business documents, owner ID, bank statements, a full product list with labels, manufacturer details, any third-party testing, your website with policies, and processing history if you have it.
No, and be wary of anyone who does. Nobody can guarantee an underwriting decision. What we can do is build your file the way supplement underwriters want to see it, before it ever reaches them.
Get a supplement merchant account built to last. Sports nutrition, wellness, weight management, and private label brands, placed with banks that understand your products.
Fast decisions for qualified businesses. No setup fees. No long-term contracts. No hidden fees.
