Re: [GRG] Aspirin, Metformin: first two human geroprotectors with high credential

Hello, please find a further response (that did not go through) from Michael Rae:


On aspirin, please see:… and references.On
metformin in Edouard’s message below: please refer to the linked post, not only the extract quoted below.See also, in normal, healthy mice (unlike all the Anisimov  studies, eg):”

Here is the answer from Michael Rae (empirically I understand it is Ok to transfer): indicated, I haven’t read the actual paper myself: I’m going off of the abstract and this statistics prof’s summary. Based on that, I
don’t think there’s any way to productively mine this specific report.If you really wanted an answer, you’d need a large linked health registry analysis lke the ones that many Nordic countries have and of which the UK has at least one, in which all members of a
large cohort are systematically tracked for health outcomes over time, to get actual life expectancy data combined with unbiased medication use records.However, at this point the rodent data suggest to me that this is not a productive use of anyone’s time or
research budget. Metformin is a healthier drug than any other if you have diabetes or metabolic syndrome; there’s no real reason to think it’s of any use to normoglycemics, or even that it’s
better in prediaabetes than diet and exercise.It is also pretty well-established that aspirin does not lower total mortality in people without previous MI or stroke, despite
its apparent benefit in reducing colon and possibly some other cancer incidence rates, particularly in susceptible populations.

Myself, I am surprised
to conclude so rapidly, but empirically Michael is right even when it surprises 😉 so I am planning to look at the two papers [1][2] in details before saying anything more about the topic (at least I will improve specific understandings on the nuances that make all the difference) and would be happy if a few others want to do the same :

[1] Estimates of benefits and harms of prophylactic use of aspirin in the general population.

[2] Can people with type 2 diabetes live longer than those without? A comparison of mortality in people initiated with metformin or sulphonylurea monotherapy and matched, non-diabetic controls
