Taking more Vitamin B, found in meat, beans and wholegrains, seems to significantly lower work-related stress.
These were the findings of a three-month trial, conducted by Con Stough, professor at Swimburne University of Technology, where participants were given a course of either high dose vitamin B supplements or a placebo.
"By lowering stress, we also lower the risk of health problems such as cardiovascular disease, depression and anxiety," Stough was quoted as saying by the journal Human Psychopharmacology.
Researchers assessed 60 participants against factors such as personality, work demands, mood, anxiety and strain and then re-evaluated them at 30 and 90 days, said Stough, according to a Swimburne statement.
"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," Stough said.
"On the other hand, those in the placebo group showed no significant change," he added.
"Vitamin B, which is found in whole unprocessed foods such as meat, beans and wholegrains, is integral to the synthesis of neurotransmitters critical to psychological wellbeing," he said.
"But the reality is that many people don't get enough Vitamin B from their diet, so they are turning to vitamin supplementation," added Stough.
