Vitamins We Test by Form

Water-Soluble Vitamins

B

Vitamin B

Forms
thiamine thiamine mononitrate riboflavin riboflavin-5′-phosphate niacin nicotinic acid niacinamide nicotinamide calcium pantothenate pantothenic acid pyridoxine pyridoxine HCl pyridoxal-5-phosphate folic acid folate biotin methylcobalamin cyanocobalamin
Matrices

powders, tablets, capsules, gummies, softgels, and water-based liquids

NOTE

We prep and test vitamin B12 in a dedicated dark room, since it’s highly light-sensitive.

C

Vitamin C

Forms
ascorbic acid sodium ascorbate calcium ascorbate magnesium ascorbate potassium ascorbate
Matrices

powders, tablets, capsules, gummies, softgels, and water-based liquids

NOTE

Vitamin C is highly sensitive to oxidation and formulation conditions, so method selection is critical for reliable results.

Validated Methods for Vitamin Quality Control

Get reproducible, defensible results across complex formulations. We validate each method for the specific vitamin and matrix, so your numbers hold up in an audit.

Matrix-appropriate extraction procedures
Validated quantitative methods
Routine system suitability verification
Automatic retesting of out-of-specification (OOS) results at no extra cost

That accuracy means fewer repeat submissions and fewer investigation delays.

Common Vitamin Questions

Why do I need to provide specifications?

Your specifications let us pick the right dilution so the vitamin concentration falls within the method’s validated measurement range. We can test without them, but that can mean a longer turnaround and a higher price.

Can one method cover every form of vitamin?

No. Vitamins exist in multiple chemical forms that behave differently across matrices, so no single method measures them all accurately. Reliable results come from vitamin-specific, matrix-appropriate methods.

Are vitamins on your ISO accreditation scope?

Yes. Every water-soluble and fat-soluble vitamin we test is on our ISO/IEC 17025:2017 accreditation scope.

What if my vitamin form isn’t on the list?

Request it. We validate new methods regularly, so a form that isn’t listed today may be available soon.
