Metformin may Slow Down Ageing, Lengthen Life Span

Metformin, the world's most widely used anti-diabetic drug, may actually slow down ageing and lengthen life span, a new study has found. In experiments reported in the journal iProceedings of the National Academy of Sciences/i, the researchers tease out the mechanism behind metformin's age-slowing effects: the drug causes an increase in the number of toxic oxygen molecules released in the cell and this, surprisingly, increases cell robustness and longevity ...
