“…Self-help approaches include exercise (Daly, 2009), dietary modifications, and use of supplements in the luteal phase of the menstrual cycle. Possible dietary modifications include reducing consumption of alcohol, caffeine, and sugar (Cunningham, Yonkers, O'Brien, & Eriksson, 2009;Rossignol & Bonnlander, 1990) and increasing complex carbohydrate intake (Sayegh, Schiff, Wurtman, Spiers, McDermott, & Wurtman, 1995). Supplements may include vitamin B6 (e.g., Wyatt, Dimmock, Jones, Shaughn O'Brien, 1999) and calcium (e.g., Thys-Jacobs, Starkey, Bernstein, & Tian, 1998), of which the latter has been acknowledged as showing some promise as a non-pharmacological potential treatment for PMDD (Rapkin & Lewis, 2013).…”
