Choline is a vital nutrient essential for maintaining liver, neurological, hematological, and skeletal muscle balance. It serves as a precursor in the biosynthesis of membrane phospholipids, like phosphatidylcholine, which aid in cell signaling and membrane transport, and is also a precursor to the neurotransmitter acetylcholine. Choline is crucial for hepatic lipid transport. In animal studies, perinatal administration of choline (18.8 mg/kg) has been shown to enhance cognitive function impaired by prenatal alcohol exposure in rats. Additionally, choline (13 mg/animal per day) improves motor coordination and addresses behavioral issues in a mouse model of Rett syndrome, and mitigates recognition memory deficits caused by early-life iron deficiency in rats when provided in drinking water at 5 ppm. Low choline intake is linked to muscle wasting, and dietary choline (1,000 mg/kg) boosts leg and breast muscle protein content in broiler chickens.
