The study, led by clinician-scientist Heike Bischoff-Ferrari and geroscientist Steve Horvath, revealed that a combination of supplements, including omega-3 and vitamin D, can slow biological ageing by three to four months over a three-year period, especially when combined with exercise.

The study tested eight different supplement/exercise combinations on its subjects: omega-3 fatty acids (1,000 mg algae supplement) and/or vitamin D (2,000 IU) daily, and/or 30 min
