Choline bitartrate
Description
Choline bitartrate (CAS 87-67-2), also known as choline hydrogen tartrate, is the tartaric acid salt form of choline used to deliver bioavailable choline in nutritional and pharmaceutical applications.
It functions as a stable, solid-form choline source preferred over more hygroscopic alternatives in dry formulations. Choline tartrate is the form most commonly referenced in bulk ingredient sourcing and manufacturing.
In dietary supplements, it serves as the active choline source in capsules, tablets, and powdered blends targeting cognitive and liver health support. Food manufacturers incorporate it into functional foods and fortified products.
Pharmaceutical formulators use it in solid oral dosage forms where consistent choline content and low moisture uptake are critical to product stability. This ensures long-term efficacy in various medical applications.
In personal care, its humectant and emulsifying properties support use in skin conditioning formulations and leave-on products. It provides versatile benefits across multiple industrial and consumer sectors.
Choline bitartrate is supplied as a white crystalline powder in both standard and anhydrous grades. Common specifications include USP, FCC, and food-grade, with BP and Ph. Eur. grades available.
Bulk packaging typically ranges from kilogram quantities up to multi-tonne lots to accommodate both R&D and commercial-scale production. This flexibility meets the needs of diverse global supply chains.
