Stability Testing

Maintaining the quality, safety, and shelf life of dietary supplements is essential for protecting consumer trust and brand reputation. Stability testing verifies that products consistently deliver their intended benefits over time, even under real-world storage and transport conditions.

At Alfa Chemistry, we provide tailored stability testing services backed by decades of industry experience, helping brands meet the highest quality standards and regulatory expectations.

Why Stability Testing Matters for Dietary Supplements

Shelf Life Validation: Confirm that your products maintain potency, quality, and safety over time, supported by real-time and accelerated stability data.
Regulatory Compliance: Meet global regulatory requirements from agencies such as the FDA and EFSA with scientifically robust studies.
Product Consistency: Ensure stable appearance, taste, texture, and efficacy throughout the product's intended shelf life.

Frequently Asked Questions

How long does stability testing usually take?

Real-time stability testing typically covers the full intended shelf life of the product, such as 12–24 months. Accelerated testing can provide predictive results within 3–6 months, depending on the formulation and regulatory requirements.

What factors can affect the stability of a dietary supplement?

Key factors include the sensitivity of active ingredients (such as vitamins or probiotics), environmental conditions like temperature, humidity, and light, packaging materials, and interactions between formulation components.

How do packaging materials influence supplement stability?

Proper packaging protects products from moisture, oxygen, and light exposure. Stability testing often includes packaging compatibility assessments to help select optimal materials that maximize shelf life and preserve quality.

What types of supplements can Alfa Chemistry test?

We test a wide variety of dietary supplements, including multivitamins, herbal extracts, probiotics, functional foods, protein powders, and specialized nutraceutical formulations.
