Choline chloride is the most widely used - and most economical - form of choline for supplementing diets. It is added as an important nutrient in poultry, pig and other animal feeds.

Generally classified as a B-complex vitamin (referred to as vitamin B4 in some publications), choline influences the metabolism of carotene and vitamin A in animals. It is in fact an essential component for ensuring the proper functioning of the nervous system. Choline plays a vital role in a number of different ways:  
1. By building and maintaining cell structures
2. By forming acetylcholine for the transmission of impulses
3. By preventing perosis in poultry
4. By building lecithin

Apart from promoting the fat metabolism in the liver (the so-called lipotropic action), choline is also a methyl group source used for transforming homocysteine into the essential amino acid methionine.
