Genetic impairments in folate enzymes increase dependence on dietary choline for phosphatidylcholine production at the expense of betaine synthesis

This randomized controlled trial investigated how genetic variations in folate-metabolizing enzymes (MTHFR, MTR, MTRR, and MTHFD1) influence choline metabolism in women, assessing whether higher choline intake could mitigate these effects. Women with genetic impairments in folate metabolism showed increased reliance on dietary choline for phosphatidylcholine (PC) synthesis, reducing availability for

Nutritional genomics: defining the dietary requirement and effects of choline

This review article explores how genetic variations affect choline metabolism and dietary requirements. It highlights that men and postmenopausal women are more likely to experience liver or muscle dysfunction when deprived of dietary choline, while premenopausal women may resist choline deficiency due to estrogen-induced expression of the PEMT gene, which
