Let's see what science has to say about the effectiveness of using zinc for these purposes.
Can zinc help you perform better cognitively?
In one study, increased zinc intake improved memory performance and reaction time scores in healthy schoolchildren .
In another study , 15mg zinc once a day had no beneficial effects on symptoms of ADHD, but 30mg zinc enabled patients to reduce amphetamine intake and still perform optimally.
To conclude, high dietary zinc intake or moderate doses of supplemented zinc may effectively enhance several aspects of cognitive performance, including memory, reaction time, and attention. However, the findings are preliminary and may not apply to healthy adults.
Can zinc help you feel better?
Women who took a multivitamin and 7mg zinc for 10 weeks were less angry and depressed than women who took only a multivitamin for 10 weeks .
In another study, 12-week supplementation with 30mg zinc decreased depression scores compared with placebo but only depressed people, not in non-depressed people . Based on this study, it appears plausible that zinc may work to bring people from a disturbed mood back to normal, but not improve mood in people who do not feel depressed.
To conclude, zinc may be an effective mood enhancer for healthy people. More research is needed before it can be known for sure.
