Dissolution Testing for Tablets & Capsules | SREKE Supplement Manufacturing Guide

Why Dissolution Testing Matters for Supplement Brands

At SREKE, we understand that dissolution testing is a critical quality control step for any tablet or capsule manufacturer. This test measures how quickly and completely an active ingredient is released from its dosage form under controlled conditions. For supplement brands, dissolution performance directly impacts bioavailability—meaning the amount of nutrient your body can actually absorb and use.

Without proper dissolution testing, even premium formulations may underperform in real-world use. Regulatory bodies including the FDA and EFSA require manufacturers to validate that their products release actives as intended. At SREKE, our GMP-certified facility in Guangzhou performs dissolution testing on every batch using USP apparatus methods, ensuring consistency and compliance.

We help brand owners avoid costly recalls, formulation failures, and regulatory delays by building dissolution verification into our development process from day one. Our team works with you to select the right dissolution media, apparatus, and testing parameters based on your product's specific formulation.

Key Manufacturing Considerations at SREKE

Dissolution Testing Standards We Follow

Our quality assurance protocols align with USP <711> Dissolution and USP <701> Disintegration standards. We also comply with FDA 21 CFR Part 111 (cGMP for dietary supplements) and ISO 22000 food safety management requirements. These frameworks ensure that our dissolution testing methods are scientifically valid and internationally recognized.

Equipment and Methodology

At SREKE, we utilize calibrated dissolution testing systems from leading manufacturers including Electrolab and Varian. Our lab is equipped for paddle (USP Apparatus 2) and basket (USP Apparatus 1) methods, with temperature control maintained at 37 ± 0.5°C. We test in appropriate dissolution media—typically 0.1N HCl, phosphate buffer, or simulated gastric fluids—selected based on your formulation's solubility profile.

Factors Affecting Dissolution Performance

Several formulation variables influence dissolution rates, and our R&D team considers each during development:

  • Particle size reduction: Micronized ingredients dissolve faster due to increased surface area
  • Excipient selection: Binders, disintegrants, and lubricants can accelerate or retard release
  • Compression force: Higher tablet hardness may slow dissolution
  • Coating thickness: Enteric or film coatings require specific pH-dependent testing
  • Capsule shell composition: Gelatin vs. HPMC shells affect disintegration time

Compliance and Documentation

Every dissolution test at SREKE generates documented results that become part of your product's technical file. We provide Certificates of Analysis (CoA), stability data, and batch records that support regulatory submissions in the US, EU, and Asia-Pacific markets. Our documentation meets FDA cGMP record-keeping requirements and EFSA novel food compliance standards.

How SREKE Helps You Get to Market Faster

Understanding dissolution requirements early in development prevents costly reformulation later. At SREKE, we integrate dissolution testing into our product development timeline from the outset. Our experienced formulators select ingredients and processing methods that optimize release profiles while maintaining stability and shelf life.

We offer flexible minimum order quantities (MOQs) starting at 5,000 units for private label products and 10,000 units for custom formulations. Lead times typically range from 4-8 weeks depending on complexity, with expedited options available for urgent launches.

Our Support Includes:

  • Formulation optimization for target dissolution profiles
  • Stability testing under ICH guidelines (25°C/60% RH and 30°C/75% RH)
  • Packaging recommendations that protect product integrity
  • Regulatory documentation for FDA, EFSA, and health authority submissions
  • Ongoing quality monitoring throughout production

Industry Trends and Market Opportunities

The global dietary supplement market continues to grow, with tablets and capsules remaining the most popular dosage forms. According to industry data, the tablet segment alone represents over 35% of global supplement sales. Brands are increasingly prioritizing products with verified bioavailability, making dissolution testing a competitive differentiator.

Clean Label and Natural Ingredients

Consumers demand transparent, clean-label formulations. At SREKE, we develop dissolution-optimized formulas using GRAS (Generally Recognized as Safe) ingredients and natural colorants. Our R&D team ensures these ingredients maintain consistent release profiles without synthetic additives.

Personalized Nutrition and Custom Formats

The rise of personalized supplementation has increased demand for specialized dissolution profiles. We support custom release technologies including immediate release, sustained release, and delayed release formulations. Our facility can produce products in various strengths and sizes to meet specific brand requirements.

Global Market Expansion

As brands expand internationally, dissolution testing becomes essential for regulatory compliance in multiple markets. SREKE's documentation supports FDA registration, EU Novel Food authorization, and ASEAN regulatory submissions. We stay current with evolving requirements from health authorities worldwide.

Frequently Asked Questions

What is the typical dissolution testing timeline?

At SREKE, standard dissolution testing takes 2-4 hours per batch, including sample preparation and analysis. For new product development, we typically run multiple test cycles during formulation optimization, which may extend the timeline to 2-3 weeks for complete method validation.

Do you test both tablets and capsules?

Yes. We perform dissolution testing on all solid oral dosage forms including tablets, hard capsules, and softgels. Each dosage form requires specific testing parameters. Tablets are tested using USP Apparatus 1 or 2, while capsules may require disintegration testing before dissolution analysis.

How do you handle difficult-to-dissolve ingredients?

For poorly soluble actives, we employ several strategies including micronization, solid dispersion technology, and surfactant-based formulations. Our R&D team conducts solubility screening and dissolution method development to ensure adequate bioavailability. We document all approaches in your product specifications.

What documentation do you provide for regulatory compliance?

We supply comprehensive documentation including Certificates of Analysis, dissolution test reports, stability data, GMP compliance certificates, and batch production records. Our documents meet FDA 21 CFR Part 111 requirements and support EFSA novel food applications. We can also provide additional testing per your market's specific regulations.

Can you help with private label products?

Absolutely. SREKE offers both OEM and ODM services for private label supplement brands. We maintain a library of proven formulations with established dissolution profiles, allowing faster time-to-market. For custom formulations, our team develops and validates dissolution methods specific to your product requirements.

What are your MOQ and lead time requirements?

Our standard MOQ is 5,000 units for private label products and 10,000 units for custom formulations. Production lead times range from 4-8 weeks depending on product complexity and packaging requirements. Rush production is available for urgent launches at additional cost.
