title: Blood magnesium constancy with vitamin B-6 supplementation in pre- and post-menopausal women.
abstract: Plasma and erythrocyte (RBC) magnesium was unchanged in ten premenopausal and seven postmenopausal subjects during the 48-day controlled study where vitamin B-6 intake was either 2.3 mg or supplemented to 10.4 mg per day. Dietary magnesium was kept at 240 to 270 mg per day throughout. All subjects were within reported normal ranges during all experimental periods for plasma and RBC magnesium. These results suggest that at usual intakes, vitamin B-6 does not influence the levels of plasma and RBC magnesium in normal women.
