'Save your money': no evidence brain health supplements work, say experts

Worldwide panel says it cannot recommend healthy people take 'memory supplements'

Dietary supplements such as vitamins do nothing to boost brain health and are simply a waste of money for healthy people, experts have said.

According to figures from the US, sales of so-called "memory supplements" doubled between 2006 and 2015, reaching a value of $643m, while more than a quarter of adults over the age of 50 in the US regularly take supplements in an attempt to keep their brain in good health.
