A seven-year study, recently published in the Journal of the American Medical Association (JAMA), claims that pregnancy supplements, taken by many women in order to boost their babies’ IQs are a waste of money.
The study was executed by the academics from South Australian Health and Medical Research Institute in Adelaide. The research included 543 women in Australia. Half of them were given supplements containing DHA for the last half of their pregnancy. Other women took dummy pills.
The scientists followed their children for 7 months and carried out tests on their development when they were 18 months old, 4 years old and then 7 years old. The researchers didn’t find any difference between their general intelligence, language skills, or overall level of IQ.
