Avoid Metformin For Longevity - Critical Side Effects! — Transcript
Full transcript
- 0:00if you are a non-diabetic who is taking
- 0:02metformin for longevity purposes I
- 0:04highly recommend you stop immediately
- 0:06hear me out and at the end of the video
- 0:07I'll share with you what to do instead
- 0:09metformin initially held great promise
- 0:12as a way to extend lifespan we had my
- 0:14starter published in 2008 showing a 37.8
- 0:17increase in lifespan and in 2014 we had
- 0:21an observational human study showing
- 0:22that diabetics who were taking metformin
- 0:24appeared to live 15 longer compared to
- 0:27non-diabetics since that initial promise
- 0:29though data has steadily trickled in
- 0:31suggesting that metformin for
- 0:33non-diabetics probably won't extend
- 0:35lifespan and actually we've got very
- 0:37good evidence now that it likely causes
- 0:39harm so let's go through everything step
- 0:42by step and then I'll share what to do
- 0:43instead starting with the 2008 paper
- 0:46showing a 37.8 increase in mice lifespan
- 0:49now these mice were shr mice and that
- 0:52stands for spontaneously hypertensive
- 0:54rats so these rats are genetically
- 0:56inbred and they develop high blood
- 0:58pressure so yes for genetically inbred
- 1:00mice who develop high blood pressure
- 1:02metformin is probably a great option but
- 1:04in 2016 the interventions testing
- 1:07program trialled normal mice in three
- 1:09separate Labs at the same time and
- 1:11Metformin did not extend lifespan so the
- 1:14pre-clinical my starter it doesn't
- 1:16really support the idea that metformin
- 1:18will extend lifespan okay but what about
- 1:20the human research well taking a closer
- 1:23look at that 2014 paper showing that
- 1:25diabetics who were taking metformin
- 1:26lived 15 percent longer this study is
- 1:29what's called an observational study
- 1:31it's looking in the rear view mirror
- 1:33this means that there's a lot of other
- 1:34factors that can skew the results but in
- 1:37October 2021 a prospective
- 1:39Interventional study was published so
- 1:41this is a study that actively made a
- 1:43change and therefore is higher up on the
- 1:45evidence pyramid compared to that 2014
- 1:48observational study the new study was
- 1:50part of the diabetes prevention program
- 1:52and it examined over 3 000 patients at
- 1:55high risk for type 2 diabetes so these
- 1:57were non-diabetics but they were
- 1:59overweight and had High fasting blood
- 2:01sugar levels half of them received
- 2:03metformin and the other half Placebo and
- 2:05over the 21-year follow-up period there
- 2:07was no significant differences in death
- 2:09rates cancer or heart disease so if
- 2:12metformin didn't provide any benefits
- 2:14for these high-risk individuals it's
- 2:16highly unlikely that metformin would
- 2:18provide any benefits for low-risk people
- 2:20overall then there's no clear benefit in
- 2:23either the my starter or the human data
- 2:25now I want to be clear not a day goes by
- 2:27at the clinic where I don't prescribe
- 2:29metformin for my pre-diabetic and type 2
- 2:31diabetic patients they absolutely should
- 2:34be on Metformin what I'm talking about
- 2:35here in this video is non-diabetics
- 2:38taking metformin for longevity purposes
- 2:40but you might be asking so what even if
- 2:43there isn't a clear benefit for
- 2:44non-diabetics to take Metformin what's
- 2:47the harm well this significant harm
- 2:49actually but before we get into that if
- 2:51you do want to accelerate your longevity
- 2:53journey and support the channel consider

- 3:16longevity research and answer questions
- 3:18proceeds go towards funding the
- 3:20rapamycin clinical study in 2019 a human
- 3:23study was published examining older
- 3:25adults at risk for developing type 2
- 3:27diabetes and they wanted to see what
- 3:29effect metformin would have on exercise
- 3:31performance over a 12-week period both
- 3:34groups performed aerobic exercise
- 3:35training and half of them took Placebo
- 3:38and the other half metformin but in the
- 3:40metformin group their VO2 max which is a
- 3:43measure of Fitness only went up by half
- 3:45compared to Placebo meaning that
- 3:47metformin significantly blunted the
- 3:49positive effects of exercise these
- 3:51findings were confirmed by a second
- 3:53study published in June 2022 showing
- 3:55that once again metformin reduced the
- 3:58VO2 max Improvement by half we've also
- 4:01got very good human research showing
- 4:03that metformin lowers testosterone
- 4:04levels in conclusion then the mice and
- 4:07human data don't show a clear benefit
- 4:09for non-diabetics instead we've got very
- 4:11good research showing that metformin
- 4:13blunts the positive effects of exercise
- 4:15and lowers testosterone levels at the
- 4:18end of the day though it's your health
- 4:19your decision I just think it's
- 4:21important that you're aware of this
- 4:23research followers of this channel will
- 4:25know that I used to take Metformin when
- 4:27I was initially sucked into the hype I
- 4:29made the decision to stop about one year
- 4:31ago and removed all of the videos that
- 4:33promoted metformin's use so you want to
- 4:35know what to do instead focus on diet
- 4:38exercise sleep socializing meditation
- 4:41and the occasional supplements such as
- 4:43creatine all of which I go through in
- 4:45this next video here a massive thank you
