Study Finds Common Mineral Could Bring PMS Relief

Comstock/Thinkstock(NEW YORK) -- Women who suffer from premenstrual syndrome, or  PMS, know the physical and emotional symptoms can often be miserable. Now researchers say a common mineral may bring relief.

Many women take iron supplements to fight fatigue. A study reported in the American Journal of Epidemiology finds that an iron-rich diet can relieve the symptoms of PMS by up to 40 percent.
The researchers at the University of Massachusetts-Amherst started studying the total iron intake -- from both diet and supplements -- of some 3,000 women without PMS.
Over 10 years, a little more than 1,000 of them were diagnosed with PMS, while the others remained free of symptoms.
Those who took in over 20 milligrams a day of iron from plant-based sources and supplements reduced their risk for PMS, according to the study findings.
Scientists think the connection is that iron is needed to produce serotonin, a brain chemical involved in regulating moods.
