The study, by researchers from Queen Margaret University in Edinburgh, involved 58 volunteers aged between 21 and 64.
By the end of the fortnight both sexes had seen ‘significantly increased’ testosterone levels.
For men this affects traits such as facial hair, a deep voice and greater sexual urges.
It is also produced in female adrenal glands and ovaries, raising a woman’s sex drive and strengthening bones and muscles.
As a side effect, increased testosterone can help raise mood and memory and even relieve stress such as ‘pre-match nerves’ or stage fright, said the study.
Previous research on pomegranate juice has found it full of antioxidants which can help ward off heart diseases and help blood circulation.
The superfood’s ingredients also help fight various forms of cancer, alleviate the symptoms of osteoarthritis and cure stomach upsets and even conjunctivitis.
The Edinburgh research measured testosterone levels, blood pressure and, using a scientific scale, levels of 11 emotions including fear, sadness, guilt, shyness and self-assurance.
Testosterone levels increased between 16 percent and 30 percent among the subjects, while blood pressure plummeted.
They also found that positive emotions rose and negative feelings fell.
