Summary

Oral contraceptive pills significantly lower serum magnesium levels in women. Further research is needed to determine if magnesium supplementation is necessary for oral contraceptive users.

Area of Science:

  • Reproductive Endocrinology
  • Nutritional Biochemistry

Context:

  • Oral contraceptives (OCs) are widely used for family planning.
  • Hormonal fluctuations can impact micronutrient levels.
  • Previous studies noted similar effects with estrogen replacement therapy.

Purpose:

  • To investigate the impact of a combined oral contraceptive on serum magnesium levels.
  • To assess changes in serum magnesium over a 6-month period.

Summary:

  • A study of 32 women using an oral contraceptive (ethinyl estradiol 0.03 mg and levonorgestrel 0.15 mg) showed a decrease in serum magnesium.
  • Mean serum magnesium decreased from 0.82 mmol/l to 0.61 mmol/l over 6 months.
  • This effect mirrors changes observed during pregnancy and estrogen therapy.

Impact:

  • Highlights a potential biochemical consequence of oral contraceptive use.
  • Suggests a need for further investigation into routine magnesium supplementation for women on OCs.
  • Informs clinical practice regarding micronutrient status in women using hormonal contraception.
