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.

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.
