A dietary ingredient derived from a melon, which is rich in antioxidant superoxide dismutase enzymes, could relieve stress, according to a study.
In the double-blind, randomised, placebo-controlled trial, researchers found that the supplement decreased the signs and symptoms of perceived stress and fatigue in healthy volunteers.
For the study, Marie-Anne Milesi from Seppic, France, worked with a team of researchers to evaluate its anti-stress effects in 70 volunteers.
Volunteers who received inactive starch capsules showed a strong placebo effect.
However, the improvements seen in the supplement group were significantly greater, especially after 28 days.
"The placebo effect was only present during the first 7 days of supplementation and not beyond. It will be interesting to confirm these effects and better understand the action of antioxidants on stress in further studies with a larger number of volunteers and a longer duration," said Milesi.
The study has been published in BioMed Central's open access Nutrition Journal.
