Quick Answer
Stability Testing for dietary supplements involves analyzing product samples using validated scientific methods to verify safety, purity, potency, and regulatory compliance. Accredited labs like Qalitex use instrumentation such as HPLC, ICP-MS, and microbiology assays to generate Certificates of Analysis (COA) required by FDA, Amazon, and retail partners.
Why Supplements Need More Than an Expiry Date
Qalitex explains why a printed expiration date alone is insufficient — brands need comprehensive stability data to validate potency, safety, and label accuracy throughout a product's lifecycle.
Dietary supplements brands require specialized testing to ensure product safety, regulatory compliance, and consumer trust. Qalitex Laboratories provides stability testing specifically designed for the dietary supplements industry. Qalitex Laboratories specializes in dietary supplement stability testing that ensures your products remain safe, potent, and effective throughout their intended shelf life. Our testing services comply with FDA regulations, follow GMP standards, and support your product's market longevity. Our testing protocols are calibrated to the unique requirements of dietary supplements products, from raw material verification to finished goods release testing.
Stability Testing Tailored for Dietary supplements
The dietary supplements industry has specific testing requirements driven by FDA regulations, marketplace compliance (Amazon, retail), and consumer safety expectations. Qalitex designs testing panels specifically for dietary supplements products, ensuring you meet all applicable standards while optimizing your testing budget. Our scientists understand the unique matrices and formulation challenges of dietary supplements products.
What Is Stability Testing and Why It Matters
Stability testing evaluates how a dietary supplement performs under various environmental conditions — temperature, humidity, and light. We conduct both real-time and accelerated stability studies per ICH Q1A(R2) guidelines, assessing active ingredient potency, microbiological integrity, packaging durability, and organoleptic properties (color, odor, texture).
Shelf Life Testing
Shelf life testing defines how long a supplement remains both safe and effective, providing the data needed for accurate expiration dating. We simulate extended storage under real and accelerated conditions, testing at 0, 1, 3, 6, and 12 months, evaluating degradation of actives and risk of microbial growth.
Our Testing Process
We test a wide range of formats: tablets, capsules, softgels, powders, gummies, and liquids. Every study includes a protocol design phase, appropriate chamber conditions (ICH Zone I–IV), testing intervals, and a final stability report with CoA documentation suitable for FDA submission.

FAQ
Frequently Asked Questions
What stability testing do dietary supplements brands need?
Dietary supplements brands typically require identity testing, purity analysis, contaminant screening (heavy metals, pesticides, microbiology), and potency verification. Specific requirements depend on the product type, target market, and applicable regulations (FDA, FTC, state laws).
Do you provide COA reports for dietary supplements products?
Yes. Every test at Qalitex generates a detailed Certificate of Analysis (COA) that includes test methods, results, specifications, and pass/fail determinations. Our COAs are accepted by FDA, Amazon, retailers, and international regulatory bodies.
Is Qalitex Laboratories ISO 17025 accredited?
Yes. Qalitex Laboratories holds ISO/IEC 17025 accreditation, the international standard for testing and calibration laboratories. This ensures our methods, equipment, and quality systems meet the highest standards of accuracy and reliability.
What is your turnaround time?
Standard turnaround is 5–7 business days. Rush service with 48-hour turnaround is available for most test types. Contact us to discuss your timeline requirements.
What types of products do you test?
Qalitex tests dietary supplements (capsules, powders, gummies, liquids), cosmetics and personal care products, food and beverage items, botanical extracts, and raw materials. We serve brands, contract manufacturers, and Amazon FBA sellers.
How do I submit samples for testing?
Ship your samples to our Irvine or San Diego laboratory with a completed sample submission form. We provide prepaid shipping labels for qualifying orders. Results are delivered electronically via secure portal.
What is the difference between real-time and accelerated stability testing?
Real-time stability testing stores products under normal conditions and tests at intervals over months or years, while accelerated stability testing uses elevated temperature and humidity to predict shelf life faster. Qalitex performs both types per ICH Q1A(R2) guidelines.
