An omega-3 dose a day could slow ageing process, ‘healthspan’ trial finds

Daily gram of essential fatty acid leads to three to four months rejuvenation of biological age' over three years

A daily dose of omega-3 oils may slow the ageing process, according to a major clinical trial of interventions that aim to extend humans' healthspan - the number of years spent in good health before a decline in old age.

Healthy older people who took one gram of the essential fatty acid for three years were found to have aged three months less than others on the trial, as measured by biological markers. Additional vitamin D and regular exercise boosted the effect to nearly four months, researchers found.
