Nutritional supplements remain a popular choice for patients seeking relief or prevention from a wide range of physical and mental disorders. Review of available literature finds support for some therapeutic uses, but flaws in study design (e.g., small sample sizes) and methodology (e.g., inadequate blinding and a lack of placebo control) limit the possibility of making strong recommendations. Quality-control issues also raise concerns about the safety of supplement use (see previous list). In addition, potential interactions with prescription drugs are another consideration (Table 1). By becoming more knowledgeable about the risks and benefits of nutritional supplements, psychiatrists can assist patients in making informed choices and avoiding unnecessary harm.
