Looking to boost your memory and concentration? You're better off eating oily fish twice a week than popping expensive herbal pills or fish oil supplements, according to a consumer survey.
Australian consumer group Choice tested several supplements and found that two weekly servings of fish rich in omega-3 fatty acids, such as sardines and salmon, can boost brain function as much as or more than pills containing ginkgo biloba, brahmi and fish oil.
Fish oil supplements were also found to contain less of the maximum daily dietary target of omega-3.
"Supplements or herbal products are not the smart option. But eating more fish certainly is," Choice spokesman Christopher Zinn said in a statement.
