Focus treatment on the patient’s predominant symptoms, whether they are physical, psychological, or mixed.
A case-control study nested within the Nurses’ Health Study II cohort showed that a high intake of both dietary calcium and vitamin D prevented the development of PMS in women ages 27 to 44.15 B vitamins, such as thiamine and riboflavin, from food sources have been associated with a lower risk of PMS.16 A variety of older clinical studies showed benefit from aerobic exercise on PMS symptoms,17-19 but a newer cross-sectional study of young adult women found no association between physical activity and the prevalence of PMS.20 Acupuncture has demonstrated efficacy for the treatment of the physical symptoms of PMS and PMDD, but more rigorous studies are needed.21,22 Cognitive behavioral therapy has been studied as a treatment, but data to support this approach are limited so it cannot be recommended at this time.23
Make the most of supplements—especially calcium
Calcium is the nutritional supplement with the most evidence to support its use to relieve symptoms of PMS and PMDD (TABLE 221,22,24-45). Research indicates that disturbances in calcium regulation and calcium deficiency may be responsible for various premenstrual symptoms. One study showed that, compared with placebo, women who took 1200 mg/d calcium carbonate for 3 menstrual cycles had a 48% decrease in both somatic and affective symptoms.24 Another trial demonstrated improvement in PMS symptoms of early tiredness, appetite changes, and depression with calcium therapy.25
Pyridoxine (vitamin B6) has potential benefit in treating PMS due to its ability to increase levels ofserotonin, norepinephrine, histamine, dopamine, and taurine.26 An older systematic review showed benefit for symptoms associated with PMS, but the authors concluded that larger randomized controlled trials (RCTs) were needed before definitive recommendations could be made.27
Chasteberry. A number of studies have evaluated the effect of vitex agnus castus (VAC), commonly referred to as chasteberry, on PMS and PMDD symptoms. The exact mechanism of VAC is unknown, but in vitro studies show binding of VAC extracts to dopamine-2 receptors and opioid receptors, and an affinity for estrogen receptors.28
A recent meta-analysis concluded that VAC extracts are not superior to selective serotonin reuptake inhibitors (SSRIs) or oral contraceptives (OCs) for PMS/PMDD.28 The authors suggested a possible benefit of VAC compared with placebo or other nutritional supplements; however, the studies supporting its use are limited by small sample size and potential bias.
