At Qalitex Inc, we provide comprehensive dietary supplement testing to help ensure the safety, quality, and compliance of your products. Our state-of-the-art lab supports brands, manufacturers, and regulatory consultants across the globe. Whether you’re testing a new botanical extract like mallow root powder for digestion, a unique Lactobacillus fermentum strain probiotic capsule, or a new hempseed protein powder isolate, we offer accurate and timely results that meet FDA, Amazon, and international standards.
Why Dietary Supplement Testing Matters
Dietary supplements are regulated under the Dietary Supplement Health and Education Act (DSHEA) and must comply with Good Manufacturing Practices (cGMPs) as outlined by the FDA. Rigorous testing ensures your products are:
-
Safe for consumption
-
Free of microbial and chemical contaminants
-
Accurately labeled
-
Compliant with domestic and international regulations
Without reliable lab testing, supplement brands risk product recalls, import refusals, and consumer mistrust. Our lab helps mitigate those risks with fast, dependable testing services.
