I see I made the video in June, 2023, so I would have been 50. But if I had waited a month or two I would have been 51. I didn’t look for the month of the video when I wrote that.
I was essentially 51, but not quite…

The reason I am including Taurine is because I generate scar tissue (internal)
My body tries to protect me from foreign objects like knee replacement parts, and generates dysregulated fibrotic tissue that restricts range of motion and causes severe SEVERE pain.
Guess what?
Taurine is anti-fibrotic
Good for all
Of you who may end up with fibrosis I heart, lung, or liver tissue. Important to know.
Rapamycun used to cover heart stents to protect them from generating the same tiype of fibrosis
That is actually why I was interested in Rapamycin in the first place - to help me with the fibrotic tissue I generate - called “ Arthrofibrosis”. Now I learn that Taurine is also a help - you can bet I will be taking it!!!

A lot of that fibrosis can contain senescent cells as well. So, yes, both taurine and Rapamycin should help with that!
A main driver of fibrotic disease is cellular senescence, a state in which cells lose the ability to divide, alter their function, and secrete various pro-inflammatory and bioreactive molecules collectively called the senescence-associated secretory phenotype (SASP) (Hernandez-Segura et al, 2018).
Cellular senescence, p21, and the path to fibrosis - PMC).
We argue that targeting senescent cells , with senolytics or senomorphs, is a viable therapeutic target in fibrotic diseases which remain largely intractable.

Thank you for your Taurine information above!! It’s surprising how helpful it is when looked into. I should not have been surprised by the Arthrofibrosis following my first knee replacement. I had experienced a number of fibrotic related type problems when I was younger: Endometriosis, frozen shoulder, and fibrocystic breast disease. An enterprising doctor here in town learned there was practically no iodine in the soil around the Great Lakes, so he conducted a study. When he provided me (and other subjects) with iodine (I think it was the atomic form, but I’m not sure) after about a year, my Endometriosis and my fibrocystic breast disease became much more normal. Unfortunately, he died of cancer, and his work was not promoted by other doctors. After that knee replacement experience, I have included iodine in my supplement list. That is helping with this revision, I think. Thank you again!!! I read all of that information very carefully.

Started taking Taurine a few months ago, and in spite of not being able to weight bear for a sustained period (knee revision surgery 3 months ago), my bone density test showed improvement, even though I have mostly forgotten my Residronate because it’s only once a week. Interesting test result!!

Not very long, so I’m posting it in full.
GPT-4o mini. The prompt was: “please compare osmotic properties of taurine and creatine in the human body”
| Property |
Taurine |
Creatine |
| Osmotic Function |
Acts as an osmolyte, helping to stabilize cell membranes and protect against osmotic stress. |
Functions as an osmolyte, particularly in muscle cells, aiding in hydration and cellular function. |
| Concentration |
Found in high concentrations in the heart, brain, and skeletal muscle. |
Primarily concentrated in muscle tissue, with smaller amounts in the brain and other tissues. |
| Mechanism of Action |
Stabilizes proteins and cellular structures, influencing ion transport and cell volume regulation. |
Increases ATP availability, which can influence osmotic balance and hydration in muscle cells. |
| Physiological Role |
Involved in bile salt formation, neurotransmission, and antioxidant defense. |
Plays a crucial role in energy metabolism, particularly during high-intensity exercise. |
| Hydration Effects |
Contributes to cellular hydration and may help prevent dehydration during stress. |
Enhances water retention in muscle cells, promoting increased muscle volume and performance. |
| Impact on Osmotic Pressure |
Helps maintain osmotic balance in cells, particularly under stress conditions. |
Affects osmotic pressure by increasing intracellular water content, which can enhance muscle performance. |
Taurine and creatine both exhibit osmotic properties that are vital for cellular function, particularly in muscle and brain tissues.
Taurine
Taurine acts as an osmolyte, stabilizing cell membranes and protecting cells from osmotic stress. It is particularly concentrated in the heart and brain, where it plays roles in neurotransmission and antioxidant defense. Taurine helps maintain osmotic balance, especially during stress, contributing to cellular hydration.
Creatine
Creatine, on the other hand, is primarily known for its role in energy metabolism. It increases the availability of ATP, which is crucial during high-intensity exercise. Creatine also influences osmotic balance by promoting water retention in muscle cells, enhancing muscle volume and performance.
Both compounds are essential for maintaining osmotic balance and cellular function, but they serve different primary roles in the body.

lol, who said this
And I don’t get the ‘OmG iTs taKInG uP sPAcE!’ complaint. (Well, if you are on dial-up, maybe I do.) Apparently some people are severely put upon by scrolling.
Anyway, if the last hold-out is on board, sell everything.
Oh, yes, I was awaiting your attention when I posted this, I’m glad to see that I anticipated your very predictable MO and here you are right on schedule. And I apologize for having made you wait anxiously for so long before obliging, I know it’s been a long wait, but here you go. Alas, you didn’t notice my explanation about the reason for posting as it relates to readability vs walls of text. Posting anything that is short and to the point here is an equivalent of quoting - when we post a study for example, we post a short quotation (if very short, in full), not the entirety of the study, we put a convenient link for the latter. Now you’re welcome to wait until I post walls of text from AI - that way you can assure yourself a good date with “never” before saying “who said this”.
I do wonder though why you decided to post your highly anticipated faux “gotcha”, not in the dedicated thread that I created specifically to discuss this issue (note: discuss with community, not attempt to dictate, which for some reason you took umbrage with), and instead put in this completely OT noise in the taurine thread - however, I don’t want you to feel unnoticed, so here’s my acknowledgment right after your comment. Enjoy!

Stanfield still believes in Taurine as do I.
According to Stanfield, it seems to help metabolic health. I also believe it reduces senescent cells. Both effects are worth taking this cheap amino acid.

I decided to go back and read what the author who designed the 2023 said here in this string of tweets.
Linking it again: https://x.com/vijayyadavlab/status/1934680200521904443?s=46
From what it sounds like, they deliberately depleted the animals of taurine so they could be deficient, and then supplemented them with taurine. Therefore, they lived 10-12% longer.
The new study says taurine doesn’t decline with aging.
Therefore, it makes sense that it would only increase lifespan in whoever is deficient, but many of us might not be deficient at any point in our lives.
Am I understanding this correctly?

The paper that showed increased lifespan with taurine supplementation in mice used “normal”/wild-type C57BL/6J mice for their lifespan study. Normal in quotations because using genetically homogenous mice makes their results less robust—this could be strain rather than species-dependent results, although the lifespan increase in both males and females is evidence against that.
They also studied taurine transporter-deficient mice in this paper, so that’s probably what you’re referring to. The primates used in their study were also normal though.
The new study says taurine doesn’t decline with aging.
Tbh the paper suggesting taurine isn’t a reliable biomarker of aging is much ado about nothing and not worthy of a publication in Science. Changes in aging aren’t always damaging, some of them are adaptive and beneficial. Hypothetically speaking, taurine could skyrocket in aging and supplementing it might still improve outcomes, which is why it’s imperative to actually do the RCTs.

I went to message the scientist and I got an AI response from Grok clarifying what he meant (AI is truly insane, btw). So perhaps I am wrong and misinterpreted what he meant.
“No, that’s not what I meant in my explanation of the 2025 study from Rafael de Cabo and colleagues (which builds critically on the 2023 taurine research). Let me clarify the details from both studies to address your question directly.
The 2023 study you’re likely referring to (published in Science and led by Vijay Yadav, with de Cabo as a co-author) observed that taurine levels naturally decline with age in mice, monkeys, and humans. To test if this age-related drop contributes to aging, researchers supplemented middle-aged mice (starting at 14 months old) with taurine at a dose that raised their blood levels back to those seen in young mice. This wasn’t done by intentionally depleting the animals of taurine first to create an artificial deficiency—instead, the control group received a standard diet, and their taurine levels followed the typical age-related decline (about 80% lower in old vs. young mice). The supplemented group showed a 10-12% increase in median lifespan and up to 25% longer life expectancy at 28 months, along with improvements in health markers like reduced inflammation and better bone density. All mice started from a baseline of normal (non-deficient) taurine levels for their age; the supplementation simply prevented or reversed the natural age-linked drop.
You’re right that this could explain some of the lifespan extension: correcting a naturally occurring deficiency (due to aging) might boost health and longevity in a way that’s harder to replicate if taurine levels aren’t dropping in the first place. However, the study also tested taurine in worms and monkeys without engineered deficiencies, and it improved healthspan (e.g., better exercise capacity in monkeys) and lifespan (in worms), suggesting benefits beyond just fixing a shortfall. That said, the 2025 de Cabo-led study (also in Science) challenges the idea of taurine decline as a universal aging driver or biomarker. Using longitudinal data from humans, monkeys, and mice on normal diets, they found taurine levels often stayed stable or even increased with age—and individual fluctuations were bigger than any age trends. This implies the 2023 benefits might be context-specific (e.g., in strains or conditions where decline does happen) rather than a broad anti-aging fix.
In short, no intentional depletion occurred in the 2023 animals; the effects stemmed from countering a real, age-driven decline. But the newer work suggests we shouldn’t overhype taurine supplements for everyone, as human data is still limited and inconsistent. If you’re considering supplementation, it’s worth discussing with a doctor, especially since a healthy diet often provides enough taurine.”

I agree that the outcome is what matters and I did allude to that earlier in the thread. I was just confused by the wording of this part of his tweet
“To find out whether changes in taurine levels affect health (or not) we accelerated taurine deficiency in animal models. Taurine deficient animals became unhealthy in many respects and lived for less time.”
That part led me to think they intentionally induced a taurine deficiency. The wording was confusing.
