Vitamins & Minerals Testing Services

Testing Services for Vitamins, Minerals, and Micronutrients

At Ayah Labs, we provide accurate, ISO/IEC 17025–aligned testing for vitamins, minerals, and other micronutrients in dietary supplements, fortified foods, and functional beverages.

Whether you’re validating a multivitamin, quantifying mineral chelates, or verifying a Nutrition Facts panel, our lab ensures every result is traceable, reproducible, and regulatory-compliant.

We work with brands, formulators, and manufacturers to ensure nutrient claims are backed by data before, during, and after production.

Common product types we test include:

• Single-ingredient supplements
• Multivitamin and multimineral blends
• Fortified foods and beverages
• Liposomal and encapsulated nutrient products
• Powder mixes and chewable/gummy formats

What We Test

Micronutrient testing is about precision, stability, and formulation compatibility. We tailor our methods to meet the specific challenges of each product type and matrix.

Single-Ingredient Vitamin and Mineral Products

Single-nutrient supplements must consistently meet label claims while remaining stable across their shelf life.

Multivitamin and Multimineral Supplements

Multis require panel testing across a broad range of nutrients, often with overlapping chemical properties.

Fortified and Functional Foods

In functional foods, micronutrient accuracy affects both efficacy and regulatory compliance. We test for correct fortification levels in diverse food matrices.

Specialty Micronutrients and Chelates

Innovative delivery forms, like chelated minerals or liposomal vitamins, require specialized testing methods for accuracy and validation.

Our Testing Capabilities

Our lab combines classical techniques with advanced instrumentation to provide consistent, reproducible data across vitamin and mineral product types.

Potency Testing

• HPLC, ICP-MS, and UV-Vis analysis of essential nutrients
• Vitamins A, B1–B12, C, D2/D3, E, K
• Minerals: calcium, magnesium, iron, zinc, selenium, iodine, and more

Stability Testing

• Accelerated and real-time shelf life studies
• Light, temperature, and oxidative stress conditions
• Time-point tracking of nutrient degradation

Contaminant Testing

• Heavy metals: lead, arsenic, cadmium, mercury (ICP-MS)
• Microbial safety: TAMC, TYMC, pathogens
• Residual solvents, pesticide residues

Label Compliance Testing

• Verification of % Daily Value (%DV) for nutrition panels
• Overages analysis to support label rounding and claim safety margins
• U.S. FDA and Canadian NNHPD format compliance

Custom Method Development

• Tailored assays for novel delivery forms and matrices
• Cross-method validation packages with full documentation

Regulatory Compliance Support

Our testing and documentation help clients meet regulatory expectations across North America and global markets.

We support compliance with:

• FDA 21 CFR Part 111 & 101 (supplement GMPs and labeling)
• Health Canada NNHPD guidelines for licensed products
• USP and AOAC-referenced test methods
• Retail and marketplace submission support (Amazon, GNC, natural health stores)
• Claim substantiation and formulation documentation for international expansion

Why Partner with Ayah Labs for Vitamin & Mineral Testing

Testing micronutrients demands more than generic lab work. It takes precision, validated methods, and formulation-aware support. Here's why clients trust us:

• Validated methods for precision and traceability — We use USP, AOAC, and in-house-validated methods tailored to your product’s format and matrix, delivering data that holds up under regulatory scrutiny.
• Deep experience with complex blends and overages — Whether it’s a densely packed multivitamin or a fortified drink mix, we know how to separate and quantify overlapping nutrients, even at low or unstable concentrations.
• End-to-end support from formulation to finished goods — We assist with R&D sampling, regulatory review, and retail submission, making sure your product is backed by solid science at every step.
• Real-time and accelerated shelf life capabilities — Monitor nutrient degradation across time and stress conditions with confidence using controlled stability protocols.
• Documentation that meets regulatory and marketplace needs — Our results are formatted for FDA audits, NNHPD submissions, and e-commerce onboarding. No surprises, just clarity.
