text: Physiologically, choline is critical for a number of functions across the life cycle which include wide-ranging roles in human metabolism from neurotransmitter synthesis to cell structure and methylation, with choline deficiency being linked to liver disease, offspring cognitive function and potential neurological disorders.7 8 Functionally choline in its oxidised form (the metabolite glycine betaine) contributes to S-adenosylmethionine synthesis – a chief methyl donor involved in DNA and histone methylation which play a central role in regulating gene expression and potentially modulating brain function.9 10 Choline also influences liver function, with shortfalls linked to defective lipoprotein metabolism, abnormal phospholipid synthesis and oxidative damage.11 Low oestrogen status (oestrogen catalyses phosphatidylcholine conversion to choline via the phosphatidylethanolamine-N-methyltransferase; PEMT enzyme) and genotype (eg, polymorphisms in the PEMT gene) can both alter choline dietary requirements.12
