Brief Summary

Multiple factors contribute to poor mental and cognitive health including well-balanced nutrition. This research project will aim to establish whether a the multivitamin Vitals+ is more effective in improving markers of health, well being and cognitive function, in healthy volunteers compared to placebo.

Participants will be screened through a phone call to ensure they meet the appropriate inclusion and exclusion criteria to enter the study before attending the clinic for tests to assess blood based vitamin and minerals levels, cognitive function, well-being questionnaires and tests to look at function of their gut barrier and activity of gut bacteria. They will then take the multi-vitamin or a placebo daily for 3 months before repeating the same tests in a second in person clinic appointment.
