Recent studies indicate that Metformin may not increase lifespan in individuals with diabetes, contradicting previous findings. While initial data suggested a potential benefit in the first three years, the trend reversed after five years in comparison to a control group. Despite this, experts like Nia remain optimistic and emphasize the importance of evidence over hope. Proposed future research includes a randomized control trial in older non-diabetic individuals to better understand Metformin's effects on aging. Although the drug is FDA approved and considered safe, further studies are needed to clarify its impact on longevity.
