Vitamin and Amino Acid Stability Studies

Contact us

Ensure label accuracy and shelf‑life claims with stability studies designed for food and supplement matrices. Eurofins Food Testing UK, working with our European vitamin competence centre in Denmark, provide real‑time and accelerated programmes for vitamins and amino acids; from study design and controlled storage to accredited analysis and clear reporting.

Why stability testing

Demonstrate that declared vitamin and amino acid levels are maintained through shelf-life
Understand the impact of temperature, humidity, light and time on product potency
Optimise formulation, packaging and overage strategy to meet end‑of‑life label targets

Study design & conditions*

Study conditions and acceptance criteria are agreed case‑by‑case to reflect your product category and market

Climate‑controlled storage using chambers aligned to ICH‑guideline style conditions
Typical long‑term (example): 25 °C / 65% RH; accelerated: 40 °C / 75% RH; other conditions available on request
Flexible schedules: common pulls at T0, 1, 3, 6, 9, 12 months, with options to 18, 24 and 36+ months

What we test

Vitamins; water‑ and fat‑soluble panels tailored to the product (e.g., beverages, cereals, supplements)
Amino acids; essential and non‑essential profiles appropriate to the matrix

Note: Analytical results represent total nutrient content; they cannot distinguish between naturally occurring and added sources.

Methods & reporting

Quantification by fit‑for‑purpose methods (e.g., HPLC/LC‑MS/MS/GC‑MS) selected for the analyte and matrix; ISO 17025 accredited where available
Results have the option of being issued in label‑ready formats for UK/EU nutrition use
Optional statistical summaries (e.g., trend charts) and interpretation aligned to your acceptance criteria

Sample management & retention

Storage of a wide range of products (soft drinks, cereals, supplements and more) for programmes of up to 3+ years
Post‑analysis retention: samples held frozen for up to 12 months to enable re‑testing where needed

Good practice tips

Provide full product information up front (formulation, packaging, target shelf-life and label claims)
Run duplicate (or triplicate) determinations at each time point for greater confidence
Reference prior test codes/batches to support continuity of evidence and trending

Comprehensive shelf-life services

Our Consultancy & Risk Management team designs and delivers end-to-end shelf-life programmes, bringing study design, accredited testing and practical guidance together so products stay safe, compliant and on-spec from launch to end-of-life.
