Why Dissolution Testing Matters for Supplement Brands

At SREKE, we know that dissolution testing is not just a regulatory checkbox—it is a fundamental predictor of product performance and consumer trust. For supplement brands, the rate and extent to which an active ingredient dissolves directly influences bioavailability, consistency, and ultimately, the efficacy your customers experience.

We follow USP <711> Dissolution and Ph. Eur. 2.9.3 standards, which are recognized globally by the FDA and EFSA for evaluating solid oral dosage forms. Our GMP-certified facility in Guangzhou integrates dissolution testing into every batch release protocol, ensuring that each tablet or capsule meets predefined specifications before it reaches your market.

Without rigorous dissolution control, even a perfectly formulated product can underperform. We help brand owners avoid costly recalls, regulatory delays, and reputational damage by embedding quality assurance into the manufacturing process from day one.

Key Manufacturing Considerations at SREKE

Dissolution Method Development & Validation

Our in-house R&D team develops method-specific dissolution profiles tailored to your formulation’s unique characteristics. We optimize parameters such as medium composition, rotation speed, and sampling intervals to ensure discriminatory testing that reflects in vivo performance. All methods are validated per ICH Q2(R1) guidelines for accuracy, precision, specificity, and robustness.

Excipient Selection & Compression Parameters

We carefully select pharmaceutical-grade excipients that support consistent disintegration and dissolution. Factors like binder type, disintegrant concentration, and compression force are meticulously controlled to prevent capping, lamination, or variable dissolution rates. Our tablets are manufactured under ISO 9001 and HACCP-certified conditions, with in-process checks at critical stages.

Capsule Shell & Fill Technology

For hard gelatin and vegetarian capsules, we evaluate shell composition, opacity, and seal integrity. Our filling lines are calibrated to deliver precise fill weights, and we conduct dissolution testing on both capsule contents and whole units when required by your specification. We comply with FDA 21 CFR Part 111 for dietary supplement GMPs and EFSA requirements for novel ingredients.

Coating & Delayed-Release Systems

When enteric or sustained-release coatings are needed, we validate dissolution profiles under simulated gastric and intestinal conditions. Our coating processes are monitored for weight gain, hardness, and film integrity, ensuring batch-to-batch consistency that meets your label claims.

• Regulatory Harmonization: Brands targeting multiple markets benefit from manufacturers who adhere to USP, Ph. Eur., and FDA GMP simultaneously, reducing duplication and compliance costs.
• Technology Integration: Advanced dissolution apparatuses and real-time release testing are becoming standard, enabling faster batch release and continuous improvement.

We invest in continuous training and equipment upgrades to keep our capabilities at the forefront, ensuring your brand can leverage these opportunities with confidence.

Frequently Asked Questions

What is dissolution testing, and why is it essential for tablets and capsules?

Dissolution testing measures how quickly and completely an active ingredient is released from its dosage form into solution. It is essential because it correlates with bioavailability and ensures that each batch delivers consistent potency, supporting product efficacy and regulatory compliance.

What standards does SREKE follow for dissolution testing?

We adhere to USP <711>, Ph. Eur. 2.9.3, and FDA guidance for dietary supplement GMPs (21 CFR Part 111). Our methods are validated per ICH Q2(R1), and we can align testing with EFSA requirements for European markets.

How does dissolution testing impact product efficacy?

If a tablet or capsule dissolves too slowly or incompletely, the active ingredient may not be adequately absorbed, reducing the supplement’s effectiveness. Our testing ensures that dissolution profiles meet your label claims, supporting the health benefits your brand promises.

Can SREKE help with formulation development?

Yes. Our R&D team assists with ingredient selection, excipient compatibility, and dosage form design. We conduct pre-production dissolution studies to optimize formulations for your target market and performance goals.

What are typical MOQs and lead times?

MOQs vary by product type and packaging; we offer flexible options for both emerging and established brands. Lead times depend on formulation complexity, testing requirements, and order volume, but we provide estimated timelines during consultation and strive for efficiency without compromising quality.

Do you provide compliance documentation?

Absolutely. We supply batch records, certificates of analysis (COAs), GMP compliance statements, and regulatory support documents. Our processes are designed to meet FDA, EFSA, and other international standards, simplifying your market entry.

How does SREKE ensure quality control throughout production?

Our Guangzhou facility is GMP-certified and follows ISO 9001 and HACCP principles. We implement in-process checks, raw material testing, and finished product dissolution validation at every stage, ensuring consistent quality from start to finish.
