FDA Warns Protein Powder Brands Over Nitrogen-Spiking Practices

The FDA issued a warning letter to protein supplement brands using non-protein nitrogen compounds to artificially inflate protein label claims — an issue detectable only through amino acid profile testing.

Looking for reliable protein & peptide testing near your location? Qalitex Laboratories operates two ISO 17025 accredited facilities in Southern California — Irvine and San Diego — serving brands nationwide with fast, accurate testing. Accurate protein and amino acid testing is critical for sports nutrition, meal replacement, and protein supplement brands. Qalitex Laboratories provides HPLC-based amino acid analysis and protein quantification methods that go beyond the Kjeldahl/Dumas total nitrogen approach to deliver true protein and individual amino acid data. Whether you need testing for dietary supplements, cosmetics, food products, or Amazon FBA compliance, our labs provide 48-hour turnaround with detailed Certificates of Analysis.

Why Choose Qalitex for Protein & Peptide Testing Near You

Qalitex Laboratories is one of the leading ISO 17025 accredited testing labs in Southern California, with facilities in both Irvine and San Diego. Our proximity to major metropolitan areas shipping hubs means faster sample receipt and quicker results. We combine state-of-the-art instrumentation (HPLC, ICP-MS, GC-MS, LC-MS/MS) with experienced scientists to deliver accurate, regulatory-ready results.

Amino Acid Profile Testing

We provide complete amino acid profiling (AAA) using HPLC with pre-column derivatization, covering all essential and non-essential amino acids. This allows verification of label claims for BCAA content (leucine, isoleucine, valine) and total amino acid spectrum.

Protein Content Quantification

We use Kjeldahl, Dumas, and HPLC methods to determine total protein content, verifiable to label claims. For collagen and hydrolyzed proteins, we apply hydroxyproline-based methods to distinguish true protein from non-protein nitrogen sources.

Adulteration & Spiking Detection

Protein spiking — adding low-cost amino acids to inflate nitrogen readings — is a known industry problem. Our comprehensive amino acid profiling detects unusual enrichment of specific amino acids, protecting your brand and customers from adulterated raw materials.
