US Merchant Account for Nutraceutical Merchants Selling supplements like Collagen Peptides, Omega-3s, and Probiotics: Regulatory Requirements Explained

If you operate an e-commerce nutraceutical business in the United States selling collagen peptides, Omega-3s, and probiotics, securing a US merchant account and Merchant ID requires compliance with payment processing standards and the US’s regulatory framework for dietary supplements. These products—collagen peptides (for skin, joint, and bone health), Omega-3s (for heart and brain health), and probiotics (for gut health)—are classified as dietary supplements under US law, subject to specific regulations but less stringent than pharmaceuticals. However, their online sale involves high-risk considerations due to consumer expectations, marketing restrictions, and fraud potential as of August 05, 2025. This section outlines the regulatory requirements for these nutraceuticals in the US, the pre-qualification process for a merchant account, and what e-commerce businesses need to prepare.

Regulatory Status of supplements likeCollagen Peptides, Omega-3s, and Probiotics in the US

Collagen peptides, Omega-3s (typically derived from fish oil or algae), and probiotics (live microbial cultures) are regulated as dietary supplements under the Dietary Supplement Health and Education Act of 1994 (DSHEA, 21 U.S.C. § 321(ff)), administered by the U.S. Food and Drug Administration (FDA). Unlike pharmaceuticals, dietary supplements do not require pre-market approval, but they must comply with specific safety, labeling, and marketing regulations enforced by the FDA and the Federal Trade Commission (FTC).

The regulatory framework includes:

• Safety and Manufacturing: Under DSHEA, manufacturers are responsible for ensuring product safety before marketing. Current Good Manufacturing Practices (cGMPs, 21 CFR Part 111) mandate quality control, testing, and documentation for dietary supplements, including collagen peptides, Omega-3s, and probiotics, to ensure purity and absence of contaminants (e.g., heavy metals in fish oil or microbial contamination in probiotics).
• Labeling: Compliance with 21 CFR Part 101 requires labels to include a “Supplement Facts” panel, listing ingredients, serving size, and no therapeutic claims (e.g., “cures arthritis” or “prevents heart disease”). Claims must be limited to “structure/function” statements (e.g., “supports joint health”) with an FDA disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”
• Marketing Restrictions: The FTC enforces truthful advertising under the FTC Act (15 U.S.C. § 45), prohibiting misleading health claims. Substantiation with competent and reliable scientific evidence is required for claims about collagen (e.g., skin elasticity), Omega-3s (e.g., cardiovascular support), or probiotics (e.g., gut health), per FDA guidance.

These products are not classified as prescription drugs, simplifying their sale compared to pharmaceuticals like Semaglutide. However, the FDA monitors adverse event reports via the Center for Food Safety and Applied Nutrition Adverse Event Reporting System (CAERS), and non-compliance (e.g., adulteration or misbranding) can lead to warning letters, recalls, or seizures under 21 U.S.C. § 342.

Pre-Qualification for a US Merchant Account with Collagen Peptides, Omega-3s, and Probiotics

For an e-commerce nutraceutical business selling collagen peptides, Omega-3s, and probiotics, pre-qualifying for a US merchant account involves meeting financial and regulatory criteria, with moderate to high-risk considerations due to the nutraceutical industry’s reputation for chargebacks and regulatory scrutiny. Payment processors like PpsRX, which handle high-risk transactions, evaluate:

1. Business Legitimacy and Documentation

• Required Documents: Business registration (e.g., Employer Identification Number from the IRS, state business license), proof of address, and ideally certifications like NSF International or USP verification for supplement quality. Processors may request evidence of compliance with FDA cGMPs, such as third-party testing certificates for product purity.
• Challenge: Processors may scrutinize businesses lacking quality certifications or those with a history of consumer complaints, particularly if sourcing from unregulated suppliers.

2. High-Risk Classification

• Nutraceutical sales are considered high-risk due to:
  
  • Frequent chargebacks from customers disputing efficacy, especially for hyped products like collagen for anti-aging or probiotics for broad health claims.
  • Regulatory scrutiny from the FDA and FTC for misleading marketing, with enforcement actions (e.g., 2024 FTC crackdowns on unsubstantiated supplement claims).
  • E-commerce risks like card-not-present fraud, subscription-based billing disputes, and international sales.
• Processors assess transaction history, fraud prevention tools (e.g., Address Verification Service, CVV2), and risk mitigation strategies to determine eligibility.

3. E-Commerce and Nutraceutical Compliance

• Website Standards: The storefront must feature SSL encryption, clear terms of service, refund policies, and compliant product descriptions. Labels and marketing must adhere to DSHEA and FTC guidelines, avoiding therapeutic claims and including FDA disclaimers. The Electronic Fund Transfer Act (15 U.S.C. § 1693) governs subscription models, requiring clear consumer consent for recurring charges.
• Supply Chain Compliance: Products must be sourced from cGMP-compliant manufacturers, with documentation to prove safety and quality. Imports must comply with FDA requirements under 21 U.S.C. § 381, with the U.S. Customs Service detaining non-compliant shipments (e.g., contaminated Omega-3s).

4. Merchant ID Assignment

• Upon pre-qualification, a Merchant ID is issued for payment processing. For nutraceuticals, conditions like moderate reserve funds or transaction monitoring may apply to mitigate chargeback and fraud risks.

Preparing for a Merchant ID Application in the US

To apply for a Merchant ID through a processor like PpsRX, e-commerce nutraceutical businesses selling collagen peptides, Omega-3s, and probiotics should prepare:

• Business Records: Full documentation proving legal operation in the US, including an EIN and state business license.
• Regulatory Compliance: Evidence of cGMP compliance (e.g., Certificates of Analysis), third-party testing results, and DSHEA-compliant labeling/marketing materials.
• Sales Data: Estimates of monthly transaction volumes, ideally from prior supplement sales, to demonstrate financial stability.
• Banking Details: A US business bank account (e.g., with Bank of America or Wells Fargo) for fund deposits.
• E-Commerce Infrastructure: Proof of a compliant storefront with secure payment gateways, fraud prevention measures, and clear refund/subscription policies.

Processors may reject applications if the business uses misleading claims, lacks quality documentation, or has a history of high chargebacks, as these increase regulatory and financial risks.

Unique Challenges for supplements like Collagen Peptides, Omega-3s, and/or Probiotics in the US

The regulatory requirements for these nutraceuticals present specific challenges for e-commerce businesses:

• Marketing Restrictions: DSHEA and FTC rules limit claims to “structure/function” statements, requiring scientific substantiation. Overhyping benefits (e.g., collagen “reversing aging” or probiotics “curing IBS”) risks FDA warning letters or FTC fines, as seen in 2023-2024 enforcement cases.
• Quality Control: Contamination risks (e.g., heavy metals in Omega-3s or non-viable probiotics) require rigorous testing to avoid FDA recalls or consumer lawsuits, increasing operational costs.
• Subscription Models: Common in nutraceutical e-commerce, subscriptions invite chargeback risks if consumers feel misled, governed by the Consumer Financial Protection Act and FTC’s Negative Option Rule.

US’s Broader Nutraceutical Oversight

The FDA monitors dietary supplements via CAERS, investigating adverse events and issuing recalls for adulterated or misbranded products under 21 U.S.C. § 342. The FTC enforces advertising compliance, with penalties up to $50,120 per violation (adjusted for 2025) under the FTC Act. State consumer protection laws (e.g., California’s Unfair Competition Law) add oversight, while the Better Business Bureau and NABP monitor online practices. Non-compliance can lead to product seizures, injunctions, or reputational damage, impacting merchant account stability.

Conclusion

Securing a US merchant account for an e-commerce nutraceutical business selling collagen peptides, Omega-3s, and probiotics requires adherence to payment processing and FDA/FTC regulations. As dietary supplements, these products face fewer barriers than pharmaceuticals but demand compliance with DSHEA, cGMPs, and truthful marketing to mitigate high-risk status. Businesses must provide robust documentation and a compliant sales model to pre-qualify successfully.
