Yes.
On any given day I can feel euphoric and attribute it something that actually has nothing to do with it. 
I have no objective or subjective reason to believe taurine is doing anything for me

They analyzed long-running data from past human, mice, and monkey studies, finding that taurine levels didn’t change much over time and widely varied between individual animals. The results suggest that taurine isn’t a good marker for age and throw into doubt the idea that it can prolong healthy aging.
Unless you’re in the business of storytelling, whether a factor increases/decreases with age is irrelevant.
The only question we should be concerned with regarding taurine supplementation is: does it increases lifespan (and/or some other measure of good health/healthspan) relative to a control group. It did that in mice relative to long-lived controls, although they weren’t genetically heterogenous. It also showed some healthspan benefits in primates as well.
Nobody was getting excited about taurine because it allegedly declined with age, it was because of the promising RCT results. So while this new paper provides valuable information about taurine’s value as a longevity biomarker, it’s a red herring with respect to taurine’s value as a longevity supplement.

Yes but the fact that Taurine declines with age in mice was a finding that made sense that supplementing with Taurine might make up for a deficiency as they aged. If that is true, and it doesn’t decline with age in humans then it may mean that we shouldn’t expect the mouse result to translate to humans.

The new paper also found an age-dependent increase in taurine levels for female C57BL/6J mice (male levels unchanged). This is the same mice strain that lived longer with taurine supplementation and where taurine levels were (perhaps erroneously) suggested to decline with age.

Could this be applied to a lot of what we talk about on this forum? Especially if the studies is done on worms or flies?

Yes, worms are particularly bad as their adult somatic cells don’t divide. However, much that normally I would not bother with any tests on worms there are times that it is useful.
In a sense people are trying to find out how cars work by seeing how far they drive in particular circumstances. It is to some extent useful, but not the best approach.

@KarlT Yes, agree with John. Rapamycin is pretty unique in that it targets a very conserved pathway so the fly and worm data adds support to its relevance in aging. I wouldn’t think anything of it unless there was mouse data and even then I’d want to see it backed up in non-human primates. All that takes time but I consider longevity data in non-mammals intriguing at best.

Can give you that… based on the information that taurine is not an anti-aging supplement because we have what we need… ok. I eat lots of meat… steak every other day. So for me meat every day… and an egg for breakfast most days.
But, I think the benefit is in that your bones are dissolving and reforming… where as we age the dissolving is not equal to rebuilding process… and leads to osteopenia… and osteoporosis.
For me, the added taurine took me from osteopenia to normal in a year’s use… 1 teaspoon in my coffee each morning.
In 1.5 years I can recheck for free… covered by insurance. And, see what changes occurred… good or bad.

Here is a compact mini review of the health benefits of taurine published in scientific papers (from consensus.ai):
“Taurine is a naturally occurring amino acid often used as a supplement, with research exploring its potential to improve various aspects of health. The evidence for taurine supplementation improving health is promising, especially for metabolic, cardiovascular, and aging-related outcomes, but most robust effects are seen in animal studies and select human populations. Large, long-term clinical trials in humans are still needed to confirm broad health benefits.
Metabolic and Cardiovascular Health
Blood Lipids and Glycemic Control: Taurine supplementation (especially at 3g/day) significantly improves triglycerides, total cholesterol, fasting insulin, and glycemic markers in overweight and obese adults, with stronger effects in those with obesity or metabolic dysfunction (Sun et al., 2024; Guan & Miao, 2020; Bae et al., 2022).
Blood Pressure: Meta-analyses show taurine can lower both systolic and diastolic blood pressure in people with liver or metabolic issues (Guan & Miao, 2020; Yamori et al., 2010; Santulli et al., 2023).
Obesity and BMI: Some studies report modest reductions in BMI and body weight, particularly in overweight individuals, but effects are not consistent across all populations (Sun et al., 2024; Guan & Miao, 2020).
Aging and Longevity
Animal Studies: Taurine supplementation extends lifespan and healthspan in mice, monkeys, and worms, improving bone, muscle, immune, and metabolic health, and reducing markers of aging such as DNA damage and inflammation (Singh et al., 2023; McGaunn & Baur, 2023; Santulli et al., 2023).
Human Data: Lower taurine levels are associated with age-related diseases, but direct evidence for anti-aging effects in humans is lacking; clinical trials are recommended (Singh et al., 2023; McGaunn & Baur, 2023; Santulli et al., 2023).
Other Health Effects
Cognitive and Physical Function in Elderly: Taurine, especially when combined with exercise, may reduce inflammation and improve physical fitness in older adults, though cognitive benefits are less clear (Chupel et al., 2021).
Cardiovascular Disease Prevention: Epidemiological studies link higher taurine intake with lower cardiovascular risk and mortality (Yamori et al., 2010; Santulli et al., 2023).
Conclusion
Taurine supplementation shows clear benefits for metabolic and cardiovascular health in at-risk populations and strong anti-aging effects in animal models. While early human data are encouraging, especially for metabolic and cardiovascular markers, more large-scale, long-term human trials are needed to confirm its broader health and longevity benefits.

If you get enough taurine in your diet, you may not need to supplement (Diet is a type of supplementation). If you are deficient or metabolically unhealthy, taurine provides a great deal of benefit. I’d say most elderly people do not get enough taurine. So, yes, taurine is beneficial for life extension.
However, if you test the effects of taurine on 20-40 y.o, healthy individuals to see if there are any benefits, you probably aren’t going to see much.

This right here.
I thought outcomes are what we are supposed to focus on? The mice and monkeys lived longer when fed a taurine diet comparable to 3-6g in a human. All this study tells us is that we might have gotten the mechanism wrong.

Anti-ageing effects of popular supplement taurine challenged
Massive study finds limited connection between ageing and taurine levels in people, monkeys and mice.
Research suggests that blood levels of the amino acid taurine might not be as closely linked to ageing as previous research had suggested. Led by scientists at the US National Institute on Aging (NIA) in Baltimore, Maryland, the study casts doubt on the use of taurine as an ageing biomarker — something that could be measured to help determine a person’s health status — and on its use as a dietary supplement to stave off the effects of ageing1.
“We clearly show that there’s no need for taurine supplementation as long as you have a healthy diet,” says Rafael de Cabo, a gerontologist at the NIA. The results were published today in Science.
Scientists not involved in the research highlight the rigour of the analysis, which looked at taurine levels in hundreds of humans over time, as well as in rhesus monkeys (Macaca mulatta) and mice. “Taurine levels were not decreasing [with age] and are not related to any abnormality that they could see in this very good longitudinal study,” says geneticist Nir Barzilai, director of the Institute for Aging Research at Albert Einstein College of Medicine in New York City. Nevertheless, the study looked only at natural taurine levels in the body, and not at whether supplements have any benefits. “That’s something that has yet to be tested,” he says.

Is taurine an aging biomarker?
Editor’s summary
Some studies (including work published in 2023 by Singh et al.) have indicated that taurine concentrations decline with age, and supplementation has been suggested to improve both healthspan and lifespan. Fernandez et al. now report results in mice, nonhuman primates, and three distinct large human cohorts studied longitudinally (i.e., with repeated measurements of the same individuals) that yield a more complex picture. The authors found large interindividual variation in circulating taurine concentrations and an increase in taurine concentrations for most cohorts during adult life. There was also no clear association of taurine concentrations with measures of health status. Thus, the possible beneficial effects of taurine supplementation are likely to depend on a range of variables and individual context. —L. Bryan Ray

How many Americans can say this?
Also, taurine-supplemented mice showed a dramatic decrease in senescent cell load in later life. OK, I agree that taurine may not be a good biomarker for aging, but I believe it has remarkable health benefits for those who are elderly and deficient. I also assume that most older people are deficient in taurine due to their diet.
For me, I’m going to continue taking taurine. It has a lot of possible upsides related to triglycerides, insulin sensitivity, senescent cell load, and cardiovascular benefits. It’s cheap as chips and it has no downside that I can tell. Worst case, I am making expensive excrement.

There’s an interesting pattern here, that we also have seen with other substances.
For exemple, Baylor human study showed that elderly men had much lower glutathione levels than young men, and supplementing with GlyNac improved many aspects of their health. However, later Nestle – that actually sells a Glynac product – published a study that there were no Glutathione level difference between younger and older men. Baylor’s older cohort were all overweight or even obese, which might explain the difference more strikingly than age.
It is also said the NAD+ levels decrease with age. While this seems to be true on average, when you look at a scatter plot chart, you see these levels are all over the place, they vary greatly individually, and many older folks have quite high NAD+ levels, that are a lot higher than those of some young people.
So this, simply said, might explaine why NMN/NR, Glynac, and possibly also Taurine appear to have great effects on some, but none on others. Maybe some people are more gullible and readily believe and report placebo effects. But maybe some people – whatever their age – are indeed NAD+, Glutathione or Taurine deficient and should thus supplement.
As far as concerned, I’ve taken Taurine (at quite a high dose, around 3g-5g) for quite some time and have never noticed an effect. I’ve taken Glynac for short periods, but at quite a low dose (500mg each), and have noticed nothing. Taking 300mg of NR has produced the noticeable effect in me that I never get hangovers. So I continued taking it, even if I don’t intend to get drunk every day, but it seems to prove to me that NR does something positive to my metabolism (detoxifying), that could also work in other ways. Charle Brenner said that 300mg NR works like an “antivirus” software, you don’t notice it, but it reparis problems when they arrive.
So maybe it’s just that I’m neither taurine nor glutathione deficient, but that I drink too much…
But supplement should be much more individualized, just like vitamins that are lifesaving if you have a serious deficiency (Vitamin C for scorbut, Niacin for Pellagra), but useless and potentially even dangerous if you don’t.
