Are zinc and antioxidant levels different in women with PMS?
Yes. Women with PMS have lower zinc and antioxidant levels than women without PMS. Antioxidant levels appear linked to diet, particularly intake of antioxidant-rich foods.
What they did
Researchers studied 110 university students aged 18-28 (48 with PMS, 62 without). They measured blood zinc and antioxidant levels and assessed diet using 24-hour dietary recall.
What they found
Women with PMS had lower serum zinc (11.67±6.42 µmol/L vs. 28.04±31.40 µmol/L in those without PMS). They also had lower antioxidant capacity (1.47±0.10 vs. 1.60±0.42 mmol/L) and higher body mass index (23.73±3.44 vs. 22.30±2.71 kg/m²). Women with PMS had lower intake of fiber, omega-3 fats, and vitamins E, B1, B2, B6, C, folate, and magnesium. Antioxidant levels were positively linked to dietary antioxidant and omega-3 fat intake.
What it means for you
Lower mineral and antioxidant levels in women with PMS appear linked to lower intake of certain nutrients in their diet. However, all participants were young university students, so findings may not apply to women of different ages.
