Choline Bitartrate

Choline bitartrate (CAS 87-67-2), also known as choline hydrogen tartrate, is the tartaric acid salt form of choline; it delivers bioavailable choline in nutritional and pharmaceutical applications.

Where is Choline Bitartrate used?

• Dietary supplements: active choline source in capsules, tablets and powdered blends for cognitive and liver health support
• Functional foods and fortified products
• Solid oral dosage forms where consistent choline content and low moisture uptake are critical to stability
• Personal care: humectant and emulsifying properties in skin conditioning formulations and leave-on products
• It is the form most commonly referenced in bulk ingredient sourcing and manufacturing.
• Anti-stress preparations.
• Infant nutrition.
• Multivitamin complexes.

Good to know: Preferred over more hygroscopic alternatives in dry formulations. Grades include USP, FCC, food-grade, BP and Ph. Eur.

Formulation notes
