91 adults experiencing heightened anxiety or stress 2–3 months following the earthquake in Christchurch were recruited to take part in this study. They were randomised to take 3 different nutritional supplements containing high levels of B vitamins as well as other nutrients indicated for cognitive health. All treatment groups experienced significant declines in psychological symptoms as well as a greater improvement in mood, anxiety and energy.
This is one of many studies showing the positive effects of optimal nutrition in managing mental health symptoms. What is being most significantly highlighted by academics is that adopting nutritional supplementation for the therapeutic treatment of mental health disorders is also very inexpensive and safe. The risk of side effects is very little, which is highlighted by the research undertaken thus far. This further underlines how micronutrient supplementation can be an easy and useful tool to adopt as an intervention for public health authorities.
