Equine supplement testing for manufacturers and product owners, planned around your formulation and label.

Supplement quality and stability

Price: Quote

Equine Supplement Quality Testing gives manufacturers and product owners analytical information about selected ingredients in their products. We develop a testing plan around the formulation, label claim and intended use of the results. Projects may include ingredient content, selected contaminants, microbiological quality and stability through storage.

How it's tested: product-specific HPLC, LC-MS, elemental or microbiological methods, chosen for each product.

Example projects

Each project is quoted per product; these are examples, not a fixed panel.

  • Vitamin E and vitamin A content, with the vitamin form defined
  • Mineral and electrolyte label verification using a defined analyte list
  • Glucosamine and MSM content in selected formulations
  • Selected botanical markers and targeted contaminants
  • Potency through storage and microbiological quality where relevant

A result for one marker does not establish complete botanical identity or absence of all prohibited substances. Ordinary achiral vitamin E analysis does not establish natural-versus-synthetic stereochemistry. Stability claims must match the products, packaging, storage conditions and time points actually studied.
