Vitamin B6 and magnesium.

J Eisinger, J Dagorn

    Magnesium
    |January 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    High doses of vitamin B6 (pyridoxine) increased erythrocyte magnesium but not intestinal absorption. Very high doses are inadvisable due to neurological risks, warranting further study on lower doses.

    Area of Science:

    • Biochemistry
    • Human Physiology
    • Nutritional Science

    Background:

    • Vitamin B6 (pyridoxine) plays a role in various metabolic processes.
    • Magnesium is an essential mineral crucial for numerous bodily functions.
    • The interaction between vitamin B6 and magnesium levels requires further elucidation.

    Purpose of the Study:

    • To investigate the effect of varying vitamin B6 doses on erythrocyte magnesium levels.
    • To assess the impact of vitamin B6 on magnesium intestinal absorption.
    • To evaluate the safety and efficacy of different vitamin B6 dosages.

    Main Methods:

    • Administration of vitamin B6 at doses of 1 g, 1.5 g/day for 2-7 weeks.
    • Magnesium balance studies with vitamin B6 doses of 500 mg, 1,000 mg, and 1,500 mg/day for 8 days.

  • Monitoring of erythrocyte magnesium levels and intestinal magnesium absorption.

    • Main Results:

    • Only high doses (1.5 g/day) of vitamin B6 significantly increased erythrocyte magnesium.
    • Vitamin B6 doses of 1 g/day or less did not affect intestinal magnesium absorption.
    • Neurological complications were observed in subjects taking 2 g/day of pyridoxine.

    Conclusions:

    • High-dose vitamin B6 may influence erythrocyte magnesium but not intestinal absorption.
    • Very high vitamin B6 doses (≥2 g/day) pose neurological risks and should be avoided.
    • Further research on long-term effects and leukocyte magnesium with lower vitamin B6 doses is recommended.
