06 Jul 2020 --- There is little evidence that vitamin, mineral and fish oil supplements protect against non-communicable diseases (NCD) despite increasing purchases from healthy people. This is according to an analysis published in the British Medicine Journal, which calls for further research to assess the long-term effects of supplements on the health of the general population and in individuals with specific nutritional needs, including those from low- and middle-income countries. These efforts, coupled with the integration of new research approaches, will better inform clinical practice and public health policies.
