Vitamins analysis
Vitamin testing for foods, supplements and fortified products
We measure fat-soluble and water-soluble vitamins in foods, beverages, nutraceuticals and fortified products, so the vitamin claims on your label are accurate and your fortification meets the standard.
Vitamin testing lab
What is vitamin analysis?
Vitamin analysis is the laboratory measurement of individual vitamins, such as A, B-complex, C, D, E and K, in a food, beverage or supplement, to verify label claims, fortification levels and nutritional quality.
Accurate Universal Laboratories Pvt. Ltd. tests vitamins in nutraceuticals, dietary supplements, fortified foods, infant and health foods, dairy products and beverages. Vitamins are separated and measured by HPLC, with LC-MS/MS used where very low levels must be measured.
Results support nutritional labelling, fortification compliance, product development and stability studies.
Launching a fortified or supplement product?
Verify vitamin content before your label goes to print.
Importance of vitamin analysis
Ensuring nutritional accuracy and product quality
Vitamins degrade with heat, light, oxygen and time. Testing confirms the amount on your label is really in the product, from the day it is made to the end of its shelf life.

FAQs
Vitamins Analysis: common questions
What is vitamin analysis?
It is the laboratory measurement of individual vitamins in a food, beverage or supplement to verify label claims, fortification levels and nutritional quality.
Which vitamins can you test?
We test fat-soluble vitamins A, D, E and K and water-soluble vitamins including vitamin C and the B-complex vitamins. Tell us the vitamins on your label and we will confirm the panel.
Which method is used for vitamin testing?
Vitamins are extracted with methods suited to each one and measured by HPLC. LC-MS/MS is used where vitamins are present at very low levels, such as vitamin D or B12.
Why do vitamin levels fall during storage?
Many vitamins are sensitive to heat, light, oxygen and moisture, so levels can drop over the shelf life. Manufacturers often add an overage and confirm it with a stability study.
Do fortified foods need vitamin testing?
Yes. Fortified foods such as oil, milk, flour and rice must contain the vitamins at the levels set by FSSAI's fortification standards, and testing is how that is verified.
How much does vitamin testing cost?
The cost depends on the number of vitamins and the product type. Share your requirement and we will send an itemised quotation.
Is Accurate Universal Laboratories accredited for this testing?
Yes. Our Ahmedabad laboratory is accredited by NABL to ISO/IEC 17025:2017 (certificate TC-5021) and our Rajkot laboratory under certificate TC-7988. The tests and products covered are listed in our scope of accreditation, and we confirm whether your parameters are within scope before testing.
