Third-Party Supplement Testing, Built Into Every NutraStar Batch
Retailers ask for it. Consumers expect it. And when a manufacturing partner can’t produce a current certificate of analysis on request, that gap becomes your problem, not theirs. At NutraStar, every batch across our supplement, sports nutrition, and functional food and beverage lines runs through cGMP-certified, FDA-registered, NSF-certified production with batch-by-batch third-party testing through our ISO 17025-accredited lab, and COAs are available on request per lot.
If you’re evaluating manufacturing partners and testing documentation is part of that decision, talk to our team about your formulation and timeline.
What Our Testing Program Actually Covers
“Third-party tested” gets used loosely across the industry, so here’s what it means when your product runs through NutraStar:
- Label claim verification: confirming your product contains what the label states, at the stated potency, on every batch
- Contaminant screening: heavy metals, microbial limits, and pesticide residues, tested independently of our internal QA process
- Identity testing: confirming raw materials are what they’re represented to be before they enter production
This runs in addition to, not instead of, our in-house QA: raw material identity checks, in-line fill and weight verification, and stability monitoring happen throughout the process. The third-party layer is the independent check on top, and it’s the documentation your retail partners and customers will ask to see.
Built for Brands That Need Retail-Ready Documentation
Major retailers and marketplaces increasingly require COAs, and in some categories, specific third-party certifications, before a SKU goes live. Brands working with manufacturers who test on a sampling basis, rather than every batch, are the ones who hit onboarding delays scrambling to produce documentation after the fact.
Because NutraStar tests every batch as standard practice, that documentation is already in place when your team needs it, whether for a retailer audit, a distributor request, or your own quality assurance program.
If your product is headed for sport or athlete-facing markets, banned-substance screening is part of the conversation too.
The Questions Brand Owners Ask Us Most
When brands are vetting NutraStar against their current or prospective manufacturer, these are the questions that come up:
- “Is every batch tested, or just a sample?” Every batch, standard.
- “Can I get a COA for a specific lot?” Yes, on request.
- “Which lab does the testing, and is it accredited?” NutraStar operates an ISO 17025-accredited in-house lab, in addition to our FDA-registered, NSF-certified manufacturing facility.
- “What’s actually tested for?” Label claim, contaminants, and identity as standard.
Switching Manufacturers Without Slowing Down
If your current manufacturer can’t answer these questions with specifics, or testing has become a recurring point of friction, that’s usually the sign it’s time to talk to a new partner, not a reason to accept the risk as the cost of doing business.
NutraStar works with brand owners at every stage, from first production run to national scale, without asking you to trade testing rigor for speed to market. Talk to our team about your formulation, your timeline, and what a switch would actually look like for your next run.
