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.

Which vitamins and minerals does Qalitex test?
Qalitex tests all major fat-soluble vitamins (A, D, E, K1, K2) and water-soluble vitamins (C, B1, B2, B3, B5, B6, B7, B9, B12) using HPLC and UV-Vis methods, plus essential minerals (calcium, magnesium, zinc, iron, selenium, chromium, and more) by ICP-MS.
What are FDA label claim tolerances for vitamins?
The FDA sets specific tolerances for nutrient content vs. label claims per USP <905> uniformity standards. Qalitex performs label claim verification testing to ensure your supplement facts panel accurately reflects actual nutrient content and meets FDA enforcement standards.
Can Qalitex test vitamin potency at end of shelf life?
Yes, Qalitex provides potency testing at both time of manufacture and end of shelf life as part of stability studies. This is critical for vitamins that degrade over time, ensuring label claims remain accurate throughout the product's expiration date.
