5 Mechanisms of Anti-Aging, Science Explained.

[@keng7758]

You have a very engaging, informative content, voice and style. Great channel! Btw, based on a new video from Dr. Brad Stanfield, I’m dropping Metformin but will continue with Berberine to lower my slightly elevated blood glucose level. I had talked my doctor into prescribing Metformin but she was right. I don’t need it and the impact it had on exercise performance and testosterone helped me decide to drop it. Good look to you!

[@Physionic]

Kind of you, Ken. Thank you. I need to re-investigate metformin. I appreciate you sharing - thank you!

[@deborahhall9744]

When you investigate Metformin please also investigate Berberine -- it has some adverse effects too. A comparison of the two with pros and cons would be helpful@@Physionic

I am mostly concerned with increasing healthspan. I am 61 and still work as a surgical tech. Have to be fast, strong and work 12 to 16 hour shifts. Thank you for your videos. I hope to omprove me gait stability and speed. Also grip strength. Much appreciated!

[@triatct]

At 63 I am very interested in a longer lifespan! At least staying healthy and active as long as possible. I just recently became obsessed with healthy lifestyle. I have been doing keto for 3 years and lost 60 pounds. I guess that's calorie restriction! I have tried different vitamins and minerals as an experiment. None seem to be noticeable to me but Ir recently since starting GLYNAC supplements and have noticed better sleep and wake up feeling clear headed and more alert. Hope that continues.

[@Physionic]

I've been really interested in your experience with GlyNAC - that seems to fit the data from the study analysis I did (I think you shared your experience there, too). Thanks for sharing!

[@K_F_fox]

After I lost a good deal of weight, even though my BMI was in excess of 26, I started experiencing skinny shaming and loss of friendships due to my insistence on maintaining the practice of "energy restriction." I'm wondering if using that branding, actually saying "energy restriction" instead of "caloric restriction" does help avoid triggering people. I've recently been told that describing my diet to doctors as "a euglycemic diet" will make my life much easier than calling it "ketogenic" or "high fat/low carb," but I haven't had the chance to try that yet.

[@Physionic]

Tell 'em to kick rocks, Kaiden. Congratulations on your success - you deserve every praise. Creative way to get around it, though - 'euglycemic diet', haha - I like it!

[@ciaranryan7303]

Barberine has been shown to be as effective at controlling blood sugar as methformin and also activates AMPK so could be a good alternative especially as in most countries methformin is only available on prescription. "Aging associated decline in intrinsic capacity" has been classed as a disease by WHO but I imagine my doctor would need a lot of convincing. 😅

[@homesignup]

Super! Thanks so much for the major anti-aging summary and mechanisms and love the pics!! Metformin is the only one I would take out because newer studies appear to show it doesn't extend lifespan in humans (though it appears to extend lifespan in yeast, worms, mice). It's great for diabetics though. I prefer berberine. I definitely do believe in calorie/energy restriction though. Fab video!🤩

[@Physionic]

I’ll have to look into it, then. Thanks for bringing it on my radar, Talia. As always. :)

[@keng7758]

@@Physionic Agree that Metformin is now regarded as not recommended unless you have diabetes or pre-diabetes. Per Dr. Brad Stanfields KZbin channel today, Metformin has been shown to reduce the effectiveness of exercise (particularly VO2 Max) and also seems to decrease testosterone. I had asked my Dr. to prescribe it and she did as I’m slightly over the line towards pre diabetes but now I’m stopping it as I now exercise regularly and will take Berberine instead. Great channel!

[@keng7758]

@@Krunch2020 Dr. Brad Stanfield is a legitimate MD in New Zealand. He also spends a great deal of his time to read published papers on the effectiveness of various medications and supplements. As he has said that he prescribes Metformin to his diabetic patients. That said, he also comments on the drawbacks of Metformin. Metformin is dirt cheap (so there is no profit in It for Pharma) so there are no large scale human studies that are currently being done on it for longevity purposes. Check your facts before you spout off please.

metformin impaired my father's kidney function seriously as he used it for over 5 years. His kidney function is now restored after being off metformin for several months.

[@tonyprice2256]

I will live as long as i can by consuming natural real foods. I am currently 66 and use absolutely no pharmaceutical products - prescribed or over the counter for any reason whatsoever. I also see no need to visit any medical doctors anytime soon at least. None of them have ever helped me reverse any of the chronic health conditions i used to have for decades, and none of them have a clue regarding basic nutrition. They are not trained to heal anything. They are only trained to manage and 'treat' chronic health conditions with pharmaceutical solutions. That is not good enough in my opinion.

[@Leto2ndAtreides]

It’s true that most are specialized. So sometimes you need to do your own research and then find the right type. I think we’re 20-ish years from fairly good age reversal tech… Would be sad to die before having a chance to be young again.

[@glorytoukraine619]

If you live in North America, you have to take all these supplements and vitamins to really eat close to "natural." Unfortunately, the food there lacks a huge amount of nutrients, unlike in Europe.

Functional med doctors focus on root cause. AI is smarter than doctors and will help us manage our health. Our bodies need supplements to fight the aging process. Food is the best medicine if you can find quality Whole Foods which is near impossible

Fantastic video, Nic! By the way, on "natural remedies" to senescence cells, I've seen this article recently that you may be interested (in case you haven't checked it yet). It argues that a substance in grape seeds is even more potent than Fisetin (a summary is extended data/fig. 1).

That's fascinating. I wonder why there was so much difference between animals. Maybe just a small sample size?

[@RosenetTV]

Hi there. First and foremost, very interesting content on your channel, you've drawn me in! Question about Berberine compared to Metformin. Dr. Sinclair has noted that Berberine works similarly to Metformin. I cannot get Metformin here with out a prescription, so I am taking Berberine instead. Any insights on Berberine in this context? Also plan to try the glyNAC combo starting this month.

[@bill9989]

I have a very basic question: I am 74 years old (yikes!!!!), non diabetic male, and have been taking metformin for almost 2 years. However, given that metformin harms or perhaps stresses the mitochondria, am I too old for it? Is my mitochondria too old and infirm to tolerate and improve from that induced stress?

[@joeschnur4632]

Check out the Kaufman protocol. Sandra ranks many compounds on cell health

[@Leto2ndAtreides]

I tried Fisetin + Quercetin. It did seem to improve my skin for a while but that was as far as I could tell in terms of obvious results. It also suffers from being difficult to absorb unless it’s in a fat absorbed form or something. Quercetin + Dasatinib probably also deserves more attention… I assume that there have been more studies.

I've been both eating turmeric, combined with black pepper, for years, and taking turmeric capsules with piperin for several months. I've been doing this because I heard, years ago, that curcumin was a powerful anti-cancer, neuro-protective (anti-Alzheimer's), has a powerful anti-inflammatory properties and now, also a senolytic. Is fisatin as mutifaceted as curcumin?

Okay, I have a difficult question: from my research, it seems Creatine upregulates both mTor and AMPK. Isn't that at oddes with each other? Also seems to decrease blood sugar levels and other stuff. Could belong on this list?

I thought that most senescent Cells are senescent because there Epigenome has changed to a point they not function like they should or they run out of telomeres.

You’re right. They reprogram through the epigenome changes. The genome itself doesn’t change.

[@donaldhenderson1870]

I take rapamycin but it does increase glyconucleogenisis. My blood glucose goes up around 10 mg/dL after taking rapamycin for several days. Its half life in your body is about 4 days and should only be taken every 10-14 days. Unfortunately, the FDA makes it hard to get. Metformin has failed thus far to extend lifespan in human studies and leads to decreases in muscle mass and aerobic performance. It also upsets my stomach something terribly. If you take rapamycin you don’t need chronic caloric restriction, however cycling between excess and deficiency on a daily of weekly basis will delivers the benefits of AMPK.

[@BillyRubinIII]

I'm interested in Rapa, I have ME/CFS and heard it can help, have you noticed any increase in energy? Am worried about sides like mouth ulcers (I already suffer with them) or loss of muscle mass? How long have you been taking it?

Can you please explain the seemingly dependent relationship between mTOR and Rapamycin? Since the "TOR" in mTOR stands for "Target Of Rapamycin", it seems logical that Rapamycin was discovered first and that the only thing known about mTOR is that it is Rapamycin's complement. Are both of my assumptions wrong or simplistic?
