Updated Studies (2020–2026)

Peer-reviewed reviews and trials added in this rebuild. Original library abstracts follow.

2020–2024 PMS micronutrients. Calcium (about 1,000–1,200 mg/day) and magnesium have the most consistent PMS trial signals among minerals; effects are modest.

These products are not intended to diagnose, treat, cure, or prevent disease. Historic abstracts below are unchanged from the original MD's Choice library.

Added studies and reviews (1998–2026)

Short notes on later trials. Original library abstracts stay below.

Thys-Jacobs et al., NEJM 1998. 1200 mg elemental calcium reduced PMS symptom scores vs placebo. Still the landmark trial cited in later reviews (2010s).
