Dietary Supplement Testing Services

Trusted Laboratory Testing for Dietary Supplements

Quality and trust are the foundation of every supplement brand. Our testing services are designed to verify ingredient identity, confirm potency, detect contaminants, and ensure stability throughout your product’s shelf life.

We work with supplement developers, manufacturers, and contract formulators across North America, helping them achieve FDA 21 CFR Part 111 compliance, support GMP certification, and validate claims for global markets.

Common product types we test include:

• Capsules, tablets, and softgels
• Powders and drink mixes
• Gummies and chews
• Liquids, oils, and tinctures
• Functional foods and nutraceutical blends

What We Test

Our lab covers a full spectrum of dietary supplement categories, each requiring specific methods, instrumentation, and expertise.

Vitamins and Minerals

We perform quantitative analysis of active ingredients using validated HPLC, ICP-MS, and UV-Vis methods to confirm potency and label accuracy.

• Vitamin and mineral assay
• Heavy metals (As, Pb, Cd, Hg)
• Nutrient stability studies

Botanical and Herbal Supplements

We verify botanical identity and quality through HPTLC, DNA barcoding, and phytochemical profiling, ensuring purity and authenticity.

• Marker compound quantification (e.g., curcuminoids, ginsenosides)
• Pesticide and solvent residue testing
• Microbial and mycotoxin screening

Adaptogens, Mushrooms, and Nootropics

Adaptogenic and cognitive-support ingredients demand precise quantification to prove functional claims.

• Beta-glucans and polysaccharide profiling
• Active compound verification (e.g., cordycepin, bacosides, lion’s mane markers)
• Identity testing for raw and blended ingredients

Marine and Protein-Based Supplements

Whether you're formulating with collagen, omega oils, peptides, or amino acids, we use advanced analytical techniques to validate bioactive content and shelf stability, especially in moisture- or oxidation-sensitive products.

• Amino acid profiling via HPLC
• Protein content via Kjeldahl or Dumas methods
• Oxidative stability and rancidity (peroxide value, anisidine value)
• Heavy metals and microplastic screening in marine-derived ingredients

Superfoods and Nutrient Blends

For complex blends like greens powders, adaptogenic stacks, or antioxidant-rich formulas, we support both label compliance and adulterant screening to maintain safety and transparency.

• Nutritional panel verification
• Adulteration testing (e.g., synthetic additives, undisclosed stimulants)
• Microbial limits testing (TAMC, TYMC, pathogens)
• Shelf life and accelerated stability testing

Regulatory Compliance Support

Navigating the regulatory environment for supplements requires scientific precision and documentation clarity. We support both pre-market and post-market compliance across North American and international regulatory bodies.

Our lab supports compliance with:

• FDA 21 CFR Part 111 & 117 (Dietary Supplement GMPs and Food Safety)
• Health Canada NNHPD (Natural Health Product Regulations)
• USP, AOAC, and FCC testing standards
• Amazon, Walmart, and other major retailers' quality requirements
