The investigators are testing the efficacy of a multi-vitamin/mineral/omega-3 complex on psychological and physiological measures in pre-menopausal women (21-40 years old) over a 12-week period.~This study will be a double-blinded, placebo-controlled intervention. Briefly, subjects will be screened for inclusion criteria. Eligible subjects will then undergo a pre-testing battery (i.e., T1) and will then be randomly assigned to one of two groups including:~Experimental group (anticipated n=50)~Control group (anticipated n=50) Subjects will then consume 2 capsules per day for 12 weeks and perform a post-testing battery (i.e., T2) that includes tests performed during the pre-testing battery.~Main outcome (dependent) variables between treatments will include:~blood levels of various micronutrients (assessed from blood draws using mass spectrometry-based assays)~blood cell gene expression patterns (assessed from blood draws and real-time PCR assays)~mood (assessed via questionnaires) Blood and questionnaires will be collected prior to supplementation, and 12 weeks into supplementation.~Statistics used to assess differences between conditions over time will include two-way repeated measures ANOVAs. When significant group*time interactions are observed, the statistical model will be decomposed using LSD post hoc tests.
The investigators are examining how the daily consumption of a multi-vitamin/mineral supplement affects the following variables in 21-40 year old women:~blood levels of various micronutrients (assessed from blood draws using mass spectrometry-based assays)~blood cell gene expression patterns (assessed from blood draws and real-time PCR assays)~mood (assessed via questionnaires) Blood and questionnaires will be collected prior to supplementation, and 12 weeks into supplementation.
