FDA enforcement of dietary supplement manufacturing is changing pattern, not simply declining. Routine facility surveillance is shrinking while targeted, AI-driven enforcement is expanding. For brands choosing a contract manufacturer, this shift changes which questions matter most and which red flags carry more weight.
Our federal regulatory snapshot covers the broad 2026 regulatory environment. This guide goes deeper on one question: what do changes in FDA enforcement capacity mean when you are evaluating manufacturers?
Dietary supplement manufacturers must comply with 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements). This includes requirements for personnel, facilities, equipment, production, laboratory operations, and record-keeping.
What Changed in FDA's Enforcement Capacity
The FDA lost 3,859 employees in 2025 and another 473 in early 2026, according to OPM Federal Workforce Data reported by FoodNavigator-USA. The agency currently employs 16,602 staff. Within those cuts, approximately 170 workers came from the Office of Inspections and Investigations, the division responsible for on-the-ground facility oversight (SupplySide).
To put the inspection math in context: in FY2024, the FDA conducted 600 dietary supplement facility inspections (510 domestic, 90 foreign). That was up from approximately 500 in FY2023. But it still covered only about 5% of the estimated 10,000 to 12,000 registered facilities (SupplySide, citing FDA Director Cara Welch).
What this guide does not claim
Supplement-specific inspection data for FY2025 and FY2026 is not yet publicly available. The workforce cuts occurred in April 2025, mid-fiscal year. We do not know with certainty how the cuts will affect supplement facility inspections specifically. The 170 inspection staff figure comes from a trade publication, not directly from the FDA. We present what we can verify and flag what remains uncertain.
How Enforcement Is Changing, Not Just Shrinking
The headline numbers might suggest that fewer inspectors means fewer inspections across the board. The data tells a more nuanced story. In FY2025, the FDA actually conducted 694 more total inspections (across all product categories) than in FY2024 (Reed Smith analysis of FDA data). But food and cosmetics warning letters decreased from 148 in FY2024 to 93 in FY2025.
Two factors explain this apparent contradiction. First, the workforce reduction occurred in April 2025, so FY2025 numbers reflect only a partial year of reduced staffing. The full impact is expected in FY2026 data. Second, the FDA is actively shifting resources from routine surveillance toward risk-based targeting.
Elsa: FDA's AI-driven enforcement tool
In June 2025, the FDA launched an internal AI system called Elsa that analyzes adverse event reports, compliance data, Form 483FDA Warning LetterA formal FDA communication notifying a company of significant regulatory violations. observations, and historical inspection outcomes to prioritize high-risk facilities for inspection (Reed Smith). This means manufacturers with prior issues may face more focused scrutiny, not less. The gap is in detection at facilities that have not been flagged yet.
Meanwhile, new enforcement priorities are emerging even with fewer staff. Component identity testing violations were cited 66 times in 2024, up from zero in 2023 (cGMP Consulting). This signals that where the FDA does inspect, it is looking more carefully at specific cGMPcGMP (Current Good Manufacturing Practice)FDA's mandatory quality standards for supplement manufacturing facilities. requirements.
What This Means When Choosing a Manufacturer
Enforcement gaps test whether a manufacturer's quality systems are self-sustaining or externally driven. A manufacturer who maintains rigorous testing because it is the right thing to do operates the same way regardless of inspection frequency. A manufacturer who treats 21 CFR Part 11121 CFR Part 111The specific FDA regulation governing dietary supplement manufacturing practices. compliance as something to prepare for when an inspector is expected becomes a higher risk when inspectors visit less often.
These red flags carry more weight when routine oversight is declining:
- No third-party audit history. If the manufacturer has never been audited by anyone other than the FDA, their external accountability depends entirely on an agency now conducting fewer routine visits.
- Certifications lapsed or self-reported without renewal evidence. A GMP certificationcGMP (Current Good Manufacturing Practice)FDA's mandatory quality standards for supplement manufacturing facilities. that expired 18 months ago tells you more about a manufacturer than one that was just renewed.
- No documented quality agreementQuality AgreementA contract defining quality responsibilities between a brand and its contract manufacturer., or a vague one. When external oversight shrinks, the specificity of your contractual quality commitments becomes the primary enforcement mechanism.
- No prior FDA inspection on record. An estimated 95% of supplement facilities are not inspected in any given year. A manufacturer that has never been inspected has had no external compliance check at all.
- Poor Form 483FDA Warning LetterA formal FDA communication notifying a company of significant regulatory violations. response history. The FDA's Elsa system uses prior inspection outcomes to target future inspections. A manufacturer with unresolved 483 observations is both a compliance risk and more likely to face focused follow-up.

Verification Signals That Replace Missing Oversight
When government inspection frequency drops, the question becomes: what other external checks can verify that a manufacturer is following Part 11121 CFR Part 111The specific FDA regulation governing dietary supplement manufacturing practices. requirements? These four signals carry the most weight.
Third-party GMP audits
NSF International, the Natural Products Association (NPA), and SQF each run accredited audit programs for supplement facilities. NSF alone audits more supplement facilities annually than the FDA does (SupplySide). These audits verify different aspects of cGMP compliance and operate on fixed schedules, unlike the FDA's variable inspection timeline. For a breakdown of what each certification actually verifies, see our certification guide.
Certification currency
Ask when a certification was last renewed, not just whether it was ever obtained. A current certificate from a recognized body means an independent auditor visited the facility within the past 12 to 24 months and found it in compliance.
Batch-specific COAsCOA (Certificate of Analysis)A document reporting test results for a specific batch of ingredients or finished product.
Request Certificates of Analysis for your specific production batches from independent testing laboratories. Generic or templated COAs that are not tied to your actual product run provide limited assurance. For how to read and evaluate a COA, see our COA reading guide.
Quality agreement specificity
A quality agreement that specifies testing protocols, release criteria, deviation handling procedures, and on-site audit rights provides enforceable accountability. A vague agreement that references "applicable regulations" without specifics provides almost none. For what to include, see our quality agreement guide.
The FDA has signaled openness to a formal third-party audit program for supplement facilities but has not made a formal proposal. Until that happens, voluntary third-party audits remain the closest substitute for routine government inspection (SupplySide, citing FDA Director Cara Welch).
Regardless of FDA staffing, the 21 CFR Part 111 requirements remain legally enforceable. Fewer inspectors does not mean fewer legal obligations.
How Inventory Ready's Assessment Accounts for Enforcement Data
Our assessment method cross-references manufacturers against the FDA enforcement database and inspection classification records. When a manufacturer has unresolved warning letters or a pattern of adverse inspection outcomes, that information factors into our assessment. See our full assessment method for details.
