Description
Choline (CAS 62-49-7) is a water-soluble nutrient classified within the B-vitamin group, also known by the names Cholinum, Vitamin J, Lipotril, and Paresan. It carries no assigned E-code in the EU. Quantities in formulations are expressed in milligrams of choline base equivalents.
In animal feed and premix production, choline supports hepatic fat metabolism, preventing fatty liver syndrome in poultry and swine at supplementation rates typically ranging from 500 to 2,000 mg per kilogram of feed. In pharmaceutical and nutraceutical applications, it serves as a precursor to the neurotransmitter acetylcholine, making it relevant to cognitive health formulations.
Choline is available in grades conforming to FCC and Ph.Eur. standards, with choline chloride being the most common commercial form for feed applications and choline bitartrate used in food and pharmaceutical contexts. Supply falls under REACH registration requirements. Packaging formats typically include drums and IBCs for liquid grades.
