Does zinc supplementation improve quality of life and sleep in young women with PMS?
Zinc improved the physical aspects of quality of life significantly but overall quality of life improvement wasn't significantly better than placebo. Sleep quality showed a small improvement in the zinc group but it wasn't statistically significant.
What they did
A randomized, double-blind, placebo-controlled trial with 60 university women. Half took 30 mg of zinc daily and half took placebo for three months. Researchers measured quality of life and sleep quality before and after using standard questionnaires.
What they found
The zinc group's quality of life score increased by 9.185 ± 7.29 (p<0.001). Physical aspects of quality of life improved much more with zinc (+5.55 ± 3.71) than placebo (+0.13 ± 2.87, p<0.001). Sleep quality improved slightly in the zinc group but not significantly (p=0.07).
What it means for you
Zinc may help the physical aspects of quality of life in young women with PMS, but doesn't clearly help overall quality of life or sleep. The study was small and limited to university women, so results may not apply to all women with PMS.
