The nutraceutical industry is booming—but with increased growth comes increased scrutiny. Regulatory bodies, retailers, and consumers alike demand high-quality, scientifically validated products. This is where a nutraceutical testing lab becomes essential.
If you’re a supplement brand, contract manufacturer, or private labeler, working with a qualified lab like Qalitex helps ensure product safety, label accuracy, and regulatory compliance. In this guide, we break down the key services you should expect from a top-tier nutraceutical testing lab and how to choose one that will support your long-term success.
What Is a Nutraceutical Testing Lab?
A nutraceutical testing lab is a specialized facility that performs scientific analyses on dietary supplements, functional foods, herbal products, and other health-focused ingestibles. These labs verify:
- Ingredient identity and concentration
- Microbial contamination
- Heavy metal content
- Stability and shelf-life
- Label claim accuracy
At Qalitex, we go beyond compliance by offering consultative support, rapid turnaround, and custom testing panels tailored to your formulation.
Core Services Offered by Nutraceutical Testing Labs
1. Identity Testing
Verifies the presence of active ingredients and herbal components using advanced techniques like HPLC, FTIR, and DNA barcoding.
2. Potency Testing
Confirms that label claims (e.g., “500 mg of Vitamin C”) are accurate and within allowable ranges.
3. Purity and Contaminant Testing
Screens for:
- Heavy metals (Lead, Mercury, Arsenic, Cadmium)
- Microbial contaminants (E. coli, Salmonella, Yeast, Mold)
- Pesticide residues
- Residual solvents
Qalitex uses validated methods like ICP-MS and GC-MS for sensitive detection of impurities.
4. Stability and Shelf-Life Studies
Determine how long your product remains safe and effective under various storage conditions. These studies are crucial for expiration dating and retailer acceptance.
5. Disintegration and Dissolution Testing
Ensures tablets and capsules break down properly for optimal bioavailability.
6. Allergen and Banned Substance Testing
Confirm the absence of allergens (e.g., gluten, soy, dairy) or substances restricted by governing bodies like WADA or NSF International.
