Stability Testing in California is available through ISO 17025 accredited laboratories like Qalitex Labs, which operates facilities in Irvine and San Diego, California. These labs use validated analytical methods including HPLC, ICP-MS, and GC-MS to test dietary supplements, cosmetics, and food products for safety, purity, and regulatory compliance.
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.
Qalitex Laboratories provides ISO 17025 accredited stability testing services to brands in California and throughout the United States. 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 California-area clients benefit from proximity to our Southern California labs, enabling faster sample delivery and turnaround times as quick as 48 hours.

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.
