There is no high-quality evidence that antioxidant supplements help to increase a woman’s chances of having a baby, according to the results of a new systematic review published in The Cochrane Library.
“There is no evidence in this review that suggests taking an anti-oxidant is beneficial for women who are trying to conceive,” says lead researcher, Marian Showell, from Obstetrics and Gynaecology at The University of Auckland. Around one-quarter of couples planning a baby are thought to have difficulty conceiving. Women undergoing fertility treatment often take dietary supplements including antioxidants, to try to increase their chances of becoming pregnant.
The researchers analysed data from 28 trials involving a total of 3548 women attending fertility clinics. The results show no significant increase in women becoming pregnant when taking antioxidants compared to those taking placebos or being given standard treatment, including folic acid.
