Benefits

Calcium is not only essential for bone, muscle, nerve, and heart health, but it also plays a significant role in supporting mood and alleviating symptoms of PMS and PMDD. Clinical studies have shown that Calcium supplementation can reduce mood swings, irritability, and anxiety linked to PMS by up to 48%, thanks to its influence on stabilising neurotransmitter activity in the brain during the menstrual cycle.Beyond its mood-enhancing effects, calcium has been found to alleviate other common PMS symptoms such as bloating, fatigue, swelling, breast pain, and backaches. Research indicates that Calcium supplementation can also help reduce the intensity of these symptoms by 30-50% in many individuals. Its ability to regulate the hormonal shifts that occur during the menstrual cycle makes it a key nutrient for comprehensive hormonal health.

Evidence

  • A systematic review of 14 studies (8 interventional, 6 observational) found that women with PMS have lower serum calcium levels and that calcium supplementation significantly reduces both the incidence and severity of PMS symptoms, underscoring a protective role for calcium in PMS management.
  • A randomised crossover trial of calcium carbonate on women with PMS showed 73% of women had fewer symptoms after 3
    months.
    Calcium eased low mood, bloating, and pain before menstruation, and also reduced menstrual cramps.
