COA Testing That Verifies What You Promise
A Certificate of Analysis serves as proof your product meets the standards you claim. At Ayah Labs, we provide COA testing services that confirm identity, potency, purity, and microbial safety for supplements, topicals, botanicals, etc. Each certificate is backed by validated methods, traceable data, and regulatory-grade documentation.
Why COA Testing Is Essential
A properly issued COA is a cornerstone of product quality, trust, and compliance. Whether you’re launching a new formula or releasing a new batch, a valid COA supports transparency at every level.
Meet FDA and GMP requirements
Our COAs support compliance with FDA 21 CFR Part 111 and cGMP quality systems, making them essential for dietary supplements and regulated consumer products.
Comply with Amazon and retailer demands
Retailers increasingly demand third-party COAs for ingestibles, cosmetics, and wellness goods. Without one, listings can be removed or shipments delayed.
Back your label claims with real data
Potency tests verify that your product contains what it says it does. Nothing more, nothing less. That’s critical for brand credibility and consumer protection.
Identify contamination before it hits production
Our testing panels screen for common contaminants like heavy metals, microbes, and residual solvents, so problems are caught before they escalate.
Strengthen trust in B2B and private label partnerships
When your name is on the label but not the manufacturing, a COA provides traceable documentation that builds trust and reduces liability.
What’s Included in a Certificate of Analysis (COA)
Every COA we issue is built around your specific product and formulation. We don’t use generic templates, only validated results that reflect your batch, your claims, and your compliance needs.
Identity confirmation using validated analytical methods
We verify the material is what it claims to be, using techniques like HPTLC, FTIR, and DNA barcoding depending on the matrix and regulations.
Potency testing for actives and claims verification
From botanical extracts to vitamins and minerals, we quantify your active ingredients using HPLC, GC-MS, or UV-Vis, whichever method is most accurate for your product.
Purity and contaminant screening
We test for heavy metals via ICP-MS, residual solvents via GC, and optional pesticide or adulterant screening based on your category or market.
Microbial safety for regulatory compliance
Our COAs can include full microbial panels - TPC, yeast, mold, and pathogen screening (e.g., E. coli, Salmonella) - to meet FDA and ISO standards.
Physical parameters like pH, moisture, and viscosity
For liquids, powders, and topicals, we include relevant physical characteristics that affect product stability, usability, and compliance.
COA Testing by Product Category
Not all COAs serve the same purpose. We tailor our reports and testing panels based on the product category and end-use expectations.
- Supplements and nutraceuticals
- Cosmetics and personal care
- Food and botanical products
- Chemicals and industrial formulations
