What Is Stability Testing for Supplements and Why It Matters
Stability testing evaluates how a dietary supplement performs under various environmental conditions, such as temperature, humidity, and light. It’s a key part of any supplement development and manufacturing program.
At Qalitex Laboratories, we conduct both real-time and accelerated stability studies, simulating different climates and storage scenarios based on ICH guidelines (ICH Q1A(R2)). These studies assess:
-
Active ingredient potency over time
-
Microbiological integrity
-
Packaging durability
-
Organoleptic properties (color, odor, texture)
We test a wide range of formats, including tablets, capsules, softgels, powders, gummies, and liquids.
For regulatory and safety purposes, our methods align with the FDA’s dietary supplement labeling guide and the USP dietary supplement standards.
Shelf Life Testing – Establishing Reliable Expiry Dates
Shelf life testing defines how long a supplement remains both safe and effective, providing the data needed for accurate expiration dating and quality assurance. It’s a critical component in product labeling and consumer trust.
Through shelf life testing, we:
-
Simulate extended storage under real and accelerated conditions
-
Perform periodic testing (e.g., at 0, 1, 3, 6, and 12 months)
-
Evaluate degradation of actives and risk of microbial growth
-
Assess packaging and ingredient interaction over time
