Choline bitartrate is a small molecular weight quaternary amine salt that readily dissociates in water. The benefit of choline salts is the rapid dissolution and availability in the body as free choline as opposed to bound forms, which need to go through several enzymatic steps before the availability of free choline. Choline bitartrate is used in many products, from infant formula to dietary supplements and fortified foods. It dissolves rapidly in the digestive system, providing the free choline needed to meet choline demands.??? ??
White cryst. powderBiological Functions
Choline Bitartrate is used by nerve cells to manufacture a chemical called acetylcholine, which effectively allows cells to communicate with each other. Choline is also heavily associated with neurological function and can help improve movement, coordination, and myofibril contraction.?? ??
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.????????? ?? ?? ? ???
