The benefits of metformin in attenuating the aging process are mainly associated with augmented autophagy, which is primarily mediated by AMPK, mammalian target of rapamycin (mTOR), NAD-dependent deacetylase sirtuin-1 (SIRT1), and insulin/IGF-1 signaling (IIS) pathways (Kim et al., 2011; Shi et al., 2012; Chen et al., 2016; Cuyas et al., 2018 . The obvious problem is that, unlike animals under investigative experimentation, humans cannot endure this degree of starvation for any significant length of time. Zhang H. Wang C. C. Liu G. H.

According to the United Nations, the number of people aged 60 years or over in the world is projected to be 1.4 billion in 2030 and 2.1 billion in 2050, hence this is a timely resource. Another vital player of vascular aging, which is positively regulated by HIF-1, is vascular endothelial growth factor (VEGF), a central mediator of angiogenesis.

Metformin is used at high doses (in the gram per day range), mediates cellular effects at rather elevated concentrations (typically in the ∼100 μM range), and influences all hallmarks of aging at multiple levels, including at the level of the intestinal microbiota (Kulkarni et al., 2020).

Benefits of Metformin in Attenuating the Hallmarks of Aging. Thus the development of sirtuin-activating compounds. A notable sirtuin-activating compound is resveratrol, originally isolated  from red wine and when concentrated (1000 fold), resveratrol produces effects similar to CR such as an increase in maximal lifespan, reduced inflammation, and delay in disease onset. In animal models of aging including the mouse, treatment with rapamycin extends the lifespan and delays the onset of age-related diseases.
