Metformin produces a gene expression pattern closely aligned with long-term calorie restriction in mice, making it a promising calorie restriction mimetic candidate.

Metformin, a common diabetes drug, has been shown in mice to activate genes similar to those activated by calorie restriction. While this makes it a candidate for anti-aging benefits, the paper does not recommend it as a standalone longevity supplement for healthy humans without medical supervision, noting it is one of several candidates under investigation.

GoodSupportsHIGH confidence
In an impressive study in mice evaluating the potential of several candidate CRM using microarray profiling, Dhahbi et al. (2005) reported that the 8 weeks’ treatment with metformin produced a gene expression pattern that was closely aligned with long-term CR.

Why this rating

Based on microarray profiling in mice showing gene alignment with CR, which is strong mechanistic evidence, though lifespan data is not the primary focus of this specific quote.
