Vitamin & Mineral Testing Services
Quantitative analysis of vitamins and minerals for accurate label claim verification.
Vitamin and mineral testing quantifies the potency of fat-soluble vitamins (A, D, E, K), water-soluble vitamins (B-complex, C), and essential minerals (calcium, zinc, iron, selenium) in dietary supplements using HPLC, UV-Vis, and ICP-MS methods to verify label claim accuracy.
Vitamins and minerals are highly regulated in dietary supplements and foods. Qalitex Laboratories provides quantitative potency testing for all major vitamins and minerals, ensuring your label claims are accurate, FDA-compliant, and defensible in audits.
Vitamins We Test
We test fat-soluble vitamins (A, D, E, K1, K2) and water-soluble vitamins (C, B1 thiamine, B2 riboflavin, B3 niacin, B5 pantothenic acid, B6 pyridoxine, B7 biotin, B9 folate, B12 cobalamin) using HPLC, UV-Vis, and microbiological assay methods.
Minerals & Trace Elements
Using ICP-MS and ICP-OES, we quantify essential minerals including calcium, magnesium, zinc, iron, copper, selenium, chromium, manganese, and iodine. Results are compared against label claims and regulatory limits (USP, EU, and national standards).
Label Claim Compliance
We help brands stay compliant with FDA label claim tolerances (USP <905> for uniformity), ensuring supplement facts panels accurately reflect nutrient content. Critical for FDA enforcement defense, retailer audits, and Amazon listing compliance.
