Nutraceutical & Supplement Testing Services

Specialized Analytical Support for Compliance, Safety, and Consumer Trust

In the modern supplement market, a label claim is only as strong as the data behind it. With increasing FDA oversight and a consumer base that demands total transparency, “standard” testing is no longer the benchmark – precision is.

At Phoslab Testing Laboratories, we provide the rigorous analytical framework necessary to move your products from the formulation stage to the retail shelf with absolute confidence. Whether you are producing complex botanicals, functional beverages, or high-potency powders, our laboratory delivers the defensible data required to protect your brand and your bottom line.

Why Quality Assurance is Your Strongest Competitive Advantage

The nutraceutical industry is currently defined by two things: rapid growth and tightening scrutiny. Manufacturers are no longer just fighting for shelf space; they are fighting to stay ahead of:

• Supply Chain Vulnerability: Verifying that raw materials from new suppliers actually contain what they claim.
• Regulatory Audits: Ensuring all data aligns with 21 CFR Part 111 (cGMP) requirements.
• Consumer Skepticism: Providing third-party validation that turns “marketing” into “proven fact.”

At Phoslab, we don’t just run samples; we help you turn compliance into a tool for market differentiation.

Comprehensive Supplement Testing Capabilities

We utilize advanced instrumentation (including HPLC, ICP-MS, and GC-MS) to provide a full suite of analytical services tailored to your specific matrix.

1. Potency & Active Ingredient Verification

We ensure your formulation matches your label. Over-formulation wastes money; under-formulation risks a Class I recall.

• Vitamins & Minerals: Full profiles including B-Complex, Fat-Soluble (A, D, E, K), and trace minerals.
• Specialty Actives: Amino acids, adaptogens, and botanical markers.

2. Contaminant & Purity Screening

Protect your brand from the heavy metals and residues that often hide in raw botanical sources.

• Heavy Metals: Low-level detection of Lead, Arsenic, Cadmium, and Mercury.
• Pesticide Residues: Comprehensive panels to ensure “Clean Label” compliance.
• Residual Solvents: Verification that extraction processes haven’t left harmful chemicals behind.

3. Microbiological Safety

Our micro-labs screen for pathogens that compromise product stability and consumer safety, helping you meet USP <2021> and <2022> standards.

• Total Aerobic Count, Yeast, and Mold.
• Pathogen screening (Salmonella, E. coli, S. aureus).

4. Stability & Shelf-Life Validation

Don’t guess on expiration dates. We conduct real-time and accelerated stability studies to track active ingredient degradation and packaging integrity over time.

Technical Support for Every Product Format

From traditional delivery systems to emerging functional food trends, we adapt our methods to your specific product matrix:

Format	Key Focus Area
Capsules & Tablets	Disintegration, dissolution, and potency.
Gummies & Softgels	Stability, thermal resistance, and active distribution.
Powders & Blends	Blend uniformity and particle size analysis.
Functional Liquids	Preservative efficacy and microbial stability.

The Phoslab Difference: More Than a Certificate of Analysis

Most labs send you a PDF and leave the interpretation to you. We take a consultative approach to laboratory science.

• Defensible Data: Our methods are validated and documented, making them ideal for regulatory reviews and retail qualification.
• Fast, Transparent Turnaround: We understand that your supply chain can’t wait. We provide clear timelines and stick to them.
• Technical Partnership: If a sample fails, we don’t just report it. We help you investigate the why so you can correct the issue at the source.

Verify Your Integrity. Protect Your Brand.
