If all the would-be mothers are thinking of taking DHA supplements hoping to boost their child's IQ, they should keep the thought aside. In latest findings from a study published in Tuesday's edition of the Journal of the American Medical Association (JAMA), researchers found that providing DHA to a baby while it is in the mother's womb does not increase their IQ levels as compared to the babies who do not get the supplement. The study was originally conducted in 2010, 2011 and 2012 when researchers in Australia enlisted 2,399 pregnant women to participate in a clinical trial. The women were divided into two groups, one of which was given capsules that comprised of 800mg of DHA per day and the others were given a placebo that did not contain DHA but had vegetable oil in it. The results of the follow up IQ test -- the Wechsler Abbreviated Scale of Intelligence, Second Edition, was conducted to assess the benefits of DHA supplements on IQ levels of 7 year olds.
