Thiamine

Thiamine, also called vitamin B1, is a water-soluble vitamin used in nutritional ingredient formulations. Commercial thiamine preparations must be identified by their chemical form and composition, rather than by the vitamin name alone.

Thiamine hydrochloride and thiamine mononitrate are different ingredient forms. Their molecular composition and handling characteristics differ, so they should not be substituted without reviewing the specification and formulation calculations. Diluted or encapsulated preparations require additional composition information.

For purchasing, confirm the vitamin assay, reporting basis and any carrier ingredients. Processing temperature, acidity and the surrounding formulation can affect stability. Evaluate the chosen preparation under the actual manufacturing and storage conditions.

Request a grade-specific technical sheet and lot certificate, including identity, assay and relevant impurity controls. Calculate vitamin contribution from the documented assay rather than the total mass of a preparation. Follow the packaging and storage instructions for the supplied form.
