According to study leader Professor Con Stough, at the beginning of the trial the researchers assessed sixty participants against factors such as personality, work demands, mood, anxiety and strain, and then re-evaluated them at 30 and 90 days.
“At the end of the three-month period, those in the Vitamin B group reported much lower levels of work stress than they did at the beginning of the trial,” he said. “In fact, participants experienced an almost 20 per cent improvement in stress levels.
“On the other hand, those in the placebo group showed no significant change.”
