Anti-diabetic drug slows aging and lengthens lifespan, animal study suggests

Researchers have provided new evidence that metformin, the world's most widely used anti-diabetic drug, slows aging and increases lifespan. Scientists teased 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 in the long term.
