An explosion of convincing animal studies further supports benfotiamine's remarkable benefits. Benfotiamine has now been shown to counteract AGE-related toxicity on endothelial cells, (43) to relieve inflammatory and neuropathic (nerve-induced) pain in both diabetic and non-diabetic rats, (44) and to alleviate diabetes-induced oxidative damage to brain tissue. (45) Interestingly, benfotiamine's protective effect on brain tissue is produced by mechanisms that seem to be unrelated to AGE formation, opening the door to even greater benefits in this area!
There is clearly no doubt that benfotiamine has proven itself in laboratory studies, and research is now yielding convincing evidence from human trials as well. Dramatic results are flowing in from top-level researchers around the world, demonstrating that benfotiamine's potent AGE/RAGE inhibition translates directly into measurable benefits for humans.

Supplements might be generally useless for lengthening Maximum lifespan, but that's a figure of merit that I don't care about. I care about mean lifespan, because that is far more likely to have an impact on my own lifespan. I also don't care about how supplements do or don't affect animals that are perfectly husbanded, because I am not perfectly husbanded. My diet is imperfect and, like Mick Jagger, I got nasty habits. (I take tea at three...) The evidence that certain supplements can improve the health, and thus increase mean lifespan, of typical humans is overwhelming. There's a real danger here of conflating things like vitamin D and Magnesium with the latest whacko herb because they all fall under the broad heading of "supplements".
Does it do anything for healthy, non-diabetic humans, in vivo? I'm 100% unimpressed by in vitro work. We already know it does good things for diabetics. Most of us are not diabetic. The decision to use it or not use it should turn on evidence of benefit in healthy humans vs. likelyhood of harm. Hormoneman, it sounds like you own a benfotiamine company.
This sounds somewhat contradictory. If it is beneficial in diabetics, it might also be in subclinical conditions.
Mean lifespan means your genetic lifespan minus all the deletive expletive happening to you in a lifetime.

I do value critical discourse, but I sense a murky line between eristic and dialectic (not in your posts). As was stated before, it's also an issue of potential gains and losses. E.g. light-heartedly dismissing the benefits of exercise (see post) is what disturbed me a bit.

Yes, that happens in a place like this... We try to steer things in the direction of logic and evidence. I think Michael was trying to stay in that mode in the linked post. I wouldn't say he was light-heartedly dismissing exercise, but that he was sticking pretty tightly to the evidence with a single-minded focus on lifespan rather than a broader look at quality of life. I'm really more interested in quality of life than quantity, though I like the idea of quantity as well. I just don't want it for its own sake. The quality has to be there too.I do value critical discourse, but I sense a murky line between eristic and dialectic (not in your posts).

Why should it? And why should you or any other healthy person suffer from untreated subclinical diabetes in the first place? (pre-diabetes is a serious condition and should be managed IAC) Taking methotrexate or taxol for cancer prevention is not a good idea either, evne though they help cancer patients.
That's what I thought before actually reading most of his posts. You couldn't be more mistaken, though. I suggest just take a look at his regimen, titled "pills, pills..." for a reason. And you couldn't be more mistaken about "listening to your body" (sorry if I despise this term, but it's quack speech). We have to listen to science: mechanstic plausibility, in vitro evidence (ok, only sometimes), observational trials, RCTs in differing population but not gut feeling!Michael seems very quick to bash out on everything but CR.

A max. increase in life span will be always (or, almost) followed by an increase in quality, but not necessarily the other way round. The decrease in quality of life is a function of intrinsic aging anyway.
Unfortunately he's right about exercise. I also wish he wasn't.

Hmm, just wanted to get my point across, but as silence is usually interpreted as consent, can't let that slip.
Supporting one's own agenda is often just a matter of picking the right studies or interpreting them accordingly, thus quite void of meaning. So getting to know your supplements (gut feeling - more quack speech?), what's good and bad for you, is very valid.
The 1-2 years michael referred to are old figures, i recall some physician admitting the numbers were far too conservative. (Will post the article if i find it, for what it's worth.)

You either get to know your supplements through science or you kill yourself.

I don't think that is the point at all to be honest. We know that exercise is a great way to 'stay young' compared to everything else we have (which is next to nothing), but it still sucks.

I doubt any form of practical CR, or any supplement (dubious) will extend ones life by much more than 5 to 10 years. Exercise might help you get more out of those years, and reduce the chance of early death... but it is unlikely to extend maximal life span.

The confusion stems from Benfotiamine's (and thiamine of course) ability to turn on the genes responsible for producing Transketolase -- there are 3 of them: TKT, TKTL1, TKTL2. Only one of these has been shown to be activated in cancer: TKTL1. In cancer, the gene gets mutated so that it constantly produces a high level of Transketolase which helps the cancer cell create as much ribose as it can from glucose, thereby providing an energy source to replicate and spread. So on the surface this seems dangerous until you realize that it doesn't mean anything unless 1.) there is a huge supply of unused glucose in the blood and 2.) the healthy cells aren't using it so that the cancer has an advantage (if every cell has Transketolase turned on, there isn't any advantage given to the cancer because it can't outproduce the healthy cells.)
So a recipe for runaway cancer with TKTL1 turned on would be very high blood sugar (like in a diabetic) and very low thiamine available to the rest of the cells. Raising the thiamine level would likely reduce the cancer's advantage, as would a low carb, low calorie diet. In addition, there are substances that are known to switch off TKTL1 like genistein from beans and soy.
For our purposes of life extension, you should already be practicing a low calorie, low glycemic diet. Adding benfotiame will help turn on all 3 of the genes mentioned above in all cells and keep you processing what low blood sugar you have though a pathway that causes the least number of methylgloxal and AGEs to develop. We want healthy stem cells, long telemeres, accurate macrophages, energetic mitochondria etc, and we want them to have the upper hand over malignant cells.

Fructose Induces Transketolase Flux to Promote Pancreatic Cancer Growth
http://cancerres.aac...70/15/6368.full
Carbohydrate metabolism via glycolysis and the tricarboxylic acid cycle is pivotal for cancer growth, and increased refined carbohydrate consumption adversely affects cancer survival. Traditionally, glucose and fructose have been considered as interchangeable monosaccharide substrates that are similarly metabolized, and little attention has been given to sugars other than glucose. However, fructose intake has increased dramatically in recent decades and cellular uptake of glucose and fructose uses distinct transporters. Here, we report that fructose provides an alternative substrate to induce pancreatic cancer cell proliferation. Importantly, fructose and glucose metabolism are quite different; in comparison with glucose, fructose induces thiamine-dependent transketolase flux and is preferentially metabolized via the nonoxidative pentose phosphate pathway to synthesize nucleic acids and increase uric acid production. These findings show that cancer cells can readily metabolize fructose to increase proliferation. They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth.

A popular vitamin supplement is being advertised with claims that are demonstrably untrue, as revealed by research published in the open access journal BMC Pharmacology.
Benfotiamine is a synthetic derivative of thiamine (vitamin B1). It is marketed heavily as a dietary supplement using a selection of unsubstantiated, 'not-quite-medical' claims that tend to characterize this field. A large part of this campaign has been built around the belief that benfotiamine is lipid-soluble and, therefore, more physiologically active. Scientific research led by Dr Lucien Bettendorff of the Center for Cellular and Molecular Neurobiology at the University of Liège, Belgium, has entirely disproved these claims.
A severe deficiency of thiamine is known to cause weight loss, emotional disturbances, impaired sensory perception, weakness and pain in the limbs, and periods of irregular heart rate. Deficiencies can occur as a result of alcoholism or malnutrition. As thiamine itself is very poorly absorbed by the body, it must be taken in as various precursor forms. This research shows that benfotiamine may not be as effective in this regard as has been claimed, in particular concerning its ability to raise effective thiamine levels in the central nervous system.
According to Bettendorff, "We suspect that those companies selling benfotiamine have poisoned much of the recent literature in an attempt to bestow it with properties that it does not have". Benfotiamine has been previously shown to prevent several diabetic complications in experimental animal models. The researchers carried out experiments in mice in which benfotiamine was administered using several different techniques and the resulting levels of thiamine were measured in various parts of the body. Contrary to other claims about its solubility, the results show that benfotiamine is only sparingly soluble in water under physiological conditions and cannot be dissolved in octanol or oils.
Due to the wide-reaching nature of the false claims about this supplement, it was important to the authors that their work be published in BMC Pharmacology as it is an open access journal that makes research freely available.

I'm taking Benfotiamine from more than 12 year BUT I'm diabetic type 1 and I know that with Benfotiamine I managed to cure a beginning of polyneuropathy
I managed to cure hypertension and after 30 years of illness I am still in good health despite a glycated hemoglobin always between 7 and 8.
But I think that isn't useful for someone who is in good health.

I'm actually interested in taking Benfotiamine... I see that it poses little to no risk of cancer from what I have read. I provided the article playing the devil's advocate. It's really easy to want something to be so true that we ignore anything that might appose our assumptions. I have been researching a number of AGE-breakers and this is one that seems to be viable. I love to hear reports like yours. Your English is fine.

When pondering the risk/reward of benfotiamine, I can't help but think, why accept any risk if traditional thiamine supplements might give the reward without the risk.
From what I've read, the problem with simple thiamine supplementation is that no mater how much you take, there is never more than one or two milligrams absorbed in a given dose. I'm rather fond of alcohol, and also consume quite a lot of antithiamine / thiaminase factors like polyphenols in tea & coffee.
My work-around for this dilemma is to take thiamine several times per day with meals that do not include antithiamine / thiaminase factors. Simple thiamine tablets typically contain 100mg of thiamine. When I tried these, I found they gave me an unusual body odor if I took this dose more than once a day. I cut the 100mg tabs into quarters, & take a quarter tab several times per day. You can get a pill cutter at any pharmacy (don't try this with a knife!)
As I take supplements with each meal, this presented no additional effort, other than cutting the tabs into quarters every morning, and avoiding taking them with meals when I will be consuming coffee or tea. Alcohol is not antithiamine/thiaminase, but simply increases physiological need/utilization, so taking thiamine with dinner/alcohol is not a problem, & helps prevent depletion from alcohol.
I feel I'm getting the best of both worlds, bumping thiamine slightly several times per day, without consuming the questionably hazardous form.
