Thread rating:  |
Bob Travis - 30 Oct 2005 23:38 GMT An elderly friend whom I frequently see at the library told me a-lipoic acid was good for diabetics. He said someone called Lester Pasternak wrote a lot on the subject. I was diagnosed with diabetes almost two years ago and this was the first I heard of it. I am wondering why the attending or the residents at our local clinic didn't tell me about this and that it could work better for diabetic neuropathy foot problems than magnetic insoles or prescription drugs. Why didn't they tell me about this study I found when searching PubMed this evening? Heck, they didn't even tell me about magnetic insoles. I found that on my own too.
I only have one actual question -- see my last paragraph. The rest of my post is one abstract and a bunch of rhetoric (perhaps mild flaming -- if so, sorry, but as many of you know numb feet are no fun).
Treatment of symptomatic diabetic polyneuropathy with the antioxidant a-lipoic acid: a meta-analysis
Diabetic Medicine Volume 21 Issue 2 Page 114 - February 2004 doi:10.1111/j.1464-5491.2004.01109.x D. Ziegler, H. Nowak*, P. Kempler, P. Vargha and P. A. Low§
Abstract
Aims: To determine the efficacy and safety of 600 mg of a-lipoic acid given intravenously over 3 weeks in diabetic patients with symptomatic polyneuropathy.
Methods: We searched the database of VIATRIS GmbH, Frankfurt, Germany, for clinical trials of a-lipoic acid according to the following prerequisites: randomized, double-masked, placebo-controlled, parallel-group trial using a-lipoic acid infusions of 600 mg i.v. per day for 3 weeks, except for weekends, in diabetic patients with positive sensory symptoms of polyneuropathy which were scored by the Total Symptom Score (TSS) in the feet on a daily basis. Four trials (ALADIN I, ALADIN III, SYDNEY, NATHAN II) comprised n = 1258 patients (a-lipoic acid n = 716; placebo n = 542) met these eligibility criteria and were included in a meta-analysis based on the intention-to-treat principle. Primary analysis involved a comparison of the differences in TSS from baseline to the end of i.v. Treatment between the groups treated with a-lipoic acid or placebo. Secondary analyses included daily changes in TSS, responder rates ( 50% improvement in TSS), individual TSS components, Neuropathy Impairment Score (NIS), NIS of the lower limbs (NIS-LL), individual NIS-LL components, and the rates of adverse events.
Results: After 3 weeks the relative difference in favour of a-lipoic acid vs. placebo was 24.1% (13.5, 33.4) (geometric mean with 95% confidence interval) for TSS and 16.0% (5.7, 25.2) for NIS-LL. The responder rates were 52.7% in patients treated with a-lipoic acid and 36.9% in those on placebo (P < 0.05). On a daily basis there was a continuous increase in the magnitude of TSS improvement in favour of a-lipoic acid vs. placebo which was noted first after 8 days of treatment. Among the individual components of the TSS, pain, burning, and numbness decreased in favour of a-lipoic acid compared with placebo, while among the NIS-LL components pin-prick and touch-pressure sensation as well as ankle reflexes were improved in favour of a-lipoic acid after 3 weeks. The rates of adverse events did not differ between the groups.
Conclusions: The results of this meta-analysis provide evidence that treatment with a-lipoic acid (600 mg/day i.v.) over 3 weeks is safe and significantly improves both positive neuropathic symptoms and neuropathic deficits to a clinically meaningful degree in diabetic patients with symptomatic polyneuropathy.

I am also wondering why the Rexall bottles of a-lipoic acid (200 mg) say to only take 200 mg per day when this abstract says take 600 mg per day? Not only that but I also read Vitamin E supplementation could help and my medical advisors did not tell me about it either. It seems that in these days of Googling you have to do everything yourself if you want any options other than what they are willing to tell you. If they know you are diabetic and they know you have neuropathies why do they just operate from the standpoint of knowledge they already have instead of researching your case individually? Isn't that why cashiers at a fast food joint make minimum wage and doctors can make $200 per hour or more? Don't they get paid more because they have more knowledge than the average person and you expect them to do their best for you to justify the high fees they charge? Otherwise I could just go to the library and have a reference librarian research my problems or just do as I did and research it myself.
Do a lot of diabetics who post here find the knowledge of many in the medical professions isn't much better than their own, especially if they are excellent web searchers and can pose succinct questions to the newsgroups?
My only genuine question for the group, however, is whether anyone else ever heard of using a-lipoic acid to treat diabetic neuropathy and does the dose have to be intravenous as was the case in this study?

People in this group have mentioned using it for that purpose. You can get time released capsules, also some take Evening primrose oil along with it. 600mg/day of ALA, I'm not sure how much EPO. First, you need to keep your BGs pretty low or it may not help, here's how: http://www.alt-support-diabetes.org/Newly%20Diagnosed.htm

Quite a few people have found that the 600 mg dose of ALA is helpful for neuropathy.
However, the other thing that has been proven to improve neuropathy in controlled trials is keeping blood sugar levels as low as possible. There's good evidence that post-meal blood sugar levels over 140 mg/dl damage the nerves and that keeping blood sugars at near normal levels can help them recover.
It's also worth noting that when nerves recover from numbness, they will hurt, so sometimes the early stages of neuropathic healing feel like it is getting worse.
So you might try a two pronged approach--lowering your post meal blood sugars to under 140 mg/dl at all times and taking the ALA. ALA combined with damagingly high blood sugar levels probably won't help all that much as the damage will be continuing.

The idea was originally based on medical research conducted in Germany, where ALA is commonly prescribed for DPN.
Here is a website which explains why. It was written by Stan Angilley, who has been a poster to this newsgroup. The site is a little long in the tooth now, but still the basis for my personal regimen.

If you choose to do further research on ALA, you may get more hits by substituting the name it is more commonly called in Europe, thioctic acid.

morrisolder@earthlink.net - 31 Oct 2005 03:58 GMT Hi Bob,
I was diagnosed after finally going to a doctor when neuropathy was making my life miserable. I knew nothing about diabetes or neuropathy until that moment, but like you I googled on neuropathy and then on "alpha lipoic acid and neuropathy." What appealed to me about it was that as opposed to everything else out there for treating nueropathy, this was the only thing that seemed to address the cause of neuropathy rather than the symptoms. ALA, and of course, lowering your blood sugar.
My doctor did not have any objection, so I started taking tha ALA, at 600 mgs per day orally, and my neuropathy did 95% reverse itself. No more pain, burning, itching, dead legs, fidgeting, restless legs--I have occasional numbness and cold feet now. I certainly can't say for sure that it was the ALA that accomplisehd that, because at the same time I brought down my A1c from 11.4 to 5.0 and have held it there for the last couple of years, although I am fairly certain that I have not kept my post prandials under 140 at all times. So it could be either or both of these things in my case. But I do know other people who have equal control of their blood sugar who are still bothered by the neuropathy in a big way, and I do know others who have taken ALA with very good results. (By know I mean that we have all posted to threads on the subject elsewhere). And other posters have said it did not help them.
As you have noticed ALA is commonly prescribed in Europe for neuropathy but not here. One reason is that it has not been approved by the FDA. Nobody has subjected it to a battery of long-term double-blind studies and presented it to the FDA for a license to distribute it. This is because these tests are expensive and there is no patent on ALA--anyone can make and distribute it. So spending the money on testing will not gurarntee a profit on it. Unfortunately that is the way our system works--even though the internet is full of studies that show that it does work!
Another claim for ALA is that it will lower blood sugar. In my experience this did not work for me. When I started and stopped and started it again, there was no real change in my blood sugar. But for that use I think the recommendation was 200 mg per day, which is probably why the Rexall bottle says that amount. And I have seen posts saying that some bottles say that diabetics should not take ALA. This could be because of the fear of being sued because someone's blood sugar, carefully controlled with insulin, might go hypo if they introduce a new factor that pushes it lower.
As to your "rhetoric or mild flaming" on doctors, it seems to me we need them to prescribe things we could not otherwise get, and we need their knowledge to point us in the right direction when our experience is insufficient to know where to go. Before diagnosis I didn't know diabetes from a whole in the wall, but my doctor recognized the symptoms immediately--even if he didn't know about ALA. Once we are pointed in the right direction, however, it can only help us to search as far and wide as we can, to learn as much as we can, because if we expect a doctor to know everything about what is ailing us, as well as everything about what is ailing all of their other patients, there will be times when we will be disappointed.

> Do a lot of diabetics who post here find the knowledge of many in the > medical professions isn't much better than their own, especially if they are > excellent web searchers and can pose succinct questions to the newsgroups? Yep. I did have one Dr. tell me to take Evening Primrose Oil, 2,000 mg twice daily for neuropathy. That really seems to help. I've tried ALA off and on and don't notice that it does anything for me.
> My only genuine question for the group, however, is whether anyone else ever > heard of using a-lipoic acid to treat diabetic neuropathy and does the dose > have to be intravenous as was the case in this study? I've heard of it. I've taken it in pill form. Don't know about intravenous. I also tried vitamin B intravenous. Seemed to help the first time, but then not after that.

Used alpha-Lipoic Acid (ALA) , 600mg/day , slow release from iHerb , for about 6 month Did not do much :(
Found out thet there may be two related problems : 1) periferal neuropathy 2)Peripheral Vascular Disease (PVD) or Peripheral Artery Desease (PAD) or Raynaud's disease or Critical Leg Ischemia
Both are caused by high blood glucose

See this link , posted by Quentin Grady : http://www.lapinskas.com and http://www.lapinskas.com/publications/3679.ppt
Started Evening Primrose Oil (EPO) a week ago No I am on 600mg/day ALA and 2000mg/day EPO Now for the first time I can clearly feel some relief :)
So.... ALA is reported to help for periferal neuropathy EPO is reported to help for Peripheral Vascular Disease
The active ingredient in EPO is believed to be gamma linoleic acid , however , the primrose oil does more than the pure substance AND there is a much higer effect if the EPO is taken together with ALA see the link to the power point presentation above.
If you Google for evening primrose oil and alpha lipoic cid you will find a large number of posts. for me there were a lot of helpfull ones by Quentin Grady

Bob Travis - 31 Oct 2005 19:17 GMT Hi Gysde,
So many good responses to my post here, good and bad results with a-lipoic (which I suppose I should have expected, but didn't; despite the article's reporting only a 24% success rate; when I saw that it looked like 100% to me), but you mention a couple of factors I had been hoping I wouldn't need to take into account, especially the second related problems you mention: circulatory. I used tobacco products until New Years Eve, 2000, and one reason I quit was due to periodontal disease. Another reason I quit was fear of oral cancer since I had been using such products since 1967. The third reason was knowledge of problems tobacco users have with something called Buerger's Disease which can cause many problems including foot numbness (http://www.wrongdiagnosis.com/b/buergers_disease/glossary.htm). For what it's worth I will be 55 this Friday.
Bottom line -- I haven't used tobacco for nearly five years. My A1Cs were 6.1 most recently -- the medical clinic staff said anything below 7 was not dangerous. I take Lantus 24 units once a day if my BG is running high, but only once every few days if ginseng, chromium piccolinate, cinnamon, a-lipoic, and Klonopin (along with moderation in diet and exercise) seems to be keeping it under control -- usually testing at less than 180 two hours after a meal and usually less than 130 anytime before a meal, and 100 to 120 when I wake up or even lower if I took my nutritional supplements the night before or 24 units of Lantus. I also keep Novolin-R on hand for BG highs but these rarely happen any more since I watch my diet a LOT better than ever before (though I know I have a ways to go -- now well over a year since diagnosis -- so I rarely doubt take Novolin any more than once often a month now, though for a time I was taking it once or twice a day (in addition to Lantus).
But I am posting now because while the foot numbness is annoying, it is not yet truly dehabilitating; nonetheless, but I would like to change my pill regimen so I have even better luck than I've been having.
I would love to thanks everyone who has offered a response but I will need to make more time for posting more replies later on. Thanks again, Gysde, and everyone else (Jenny, J.C., Morris, Julie, and Annette -- God, Annette, what a compendium of info. Will need to reread yours and everyone elses replies before I write again.

>I used tobacco products until New Years Eve, 2000, and one >reason I quit was due to periodontal disease. So did I - and I had perio for 20 years before that. No-one ever mentioned a link. I had a dramatic improvement within six months of quitting in may 2001. <snip>
>My A1Cs were 6.1 most recently -- the medical clinic staff said anything below 7 was not dangerous. It won't hurt them at all:-)
6.1 ain't bad compared to the average - but under 5 is better. More importantly, I found a much more direct relationship between my post-prandial BGS and my periodontal health than the A1c. My second dramatic reduction in perio problems came from following Jennifer's "test, test, test" advice - even before it showed up in better A1c.

Those would be scary numbers for me - and I suspect they may be part of the reason for your other problems, despite your "good" A1c. My present A1c has crept up higher than yours (so I started metformin)- but I get very annoyed with myself if I exceed 7.8(140) at one hour and I do a full review of the menu if it's over 6.5(115) at two hours.

And this link to see what you can do to correct it: http://www.alt-support-diabetes.org/NewlyDiagnosed.htm
I know you aren't newly diagnosed, but the recommendations remain the same - I know you watch your diet, but are you looking for the right things? <snip>
>But I am posting now because while the foot numbness is annoying, it is not >yet truly dehabilitating; nonetheless, but I would like to change my pill >regimen so I have even better luck than I've been having. I resisted meds for a long time. For type 2 I see them as an aid to the correct diet and exercise regimen, not as an alternative. Even the best modern medications won't cover for the wrong way of eating and lifestyle in the long term, and they will work far more effectively if the basic platform is sound.
I am not criticising your current diet and exercise - it may be the best possible for you - but the numbers you quoted imply otherwise.
Take whatever supplements you feel may help - personally, I think you'll improve things much more if you read the "test, test, test" advice and put it into practice.
Cheers, Alan, T2, Australia.

Thanks for refreshing my memory. It has been a long time since I visited EPO in combination Vit C and in combination with lipoic acid. I remembered that the combination worked but had forgotten the pathways. One of the great virtues of alt.support.diabetes is that we remind one another to revisit things we had considered and since past on from. As we learn more we are better able to appreciate the significance of other facts such as the various pathways involved and their implications for diabetics. Little details come into clear focus such as sorbitol not crossing membranes and hence the vital importance of decreasing its production by A. controlling glucose levels and B. ensuring one's diet is rich in alpha reductase inhibitors, eg quercetin from onions or the Japanese herb, Perilla Fruitescens, (purple perilla).

Slip of the pen or do you mean aldose reductase inhibitors , or are they just the same ?? I did not know that Quercetin is one from onions or Japanese herb, Perilla Fruitescens, (purple perilla)
I found that the sorbitol pathway can be inhibited by Aldose Reductase Inhibitors and that a number of substances were tested by the pharmaceutical companies with mixed succes . Some had very bad side effects. There seems to be much more about aldose reductase. I found a recent review :
Endocrine Reviews 26 (3): 380-392 Copyright © 2005 by The Endocrine Society
Role of Aldose Reductase and Oxidative Damage in Diabetes and the Consequent Potential for Therapeutic Options
Aldose reductase (AR) is widely expressed aldehyde-metabolizing enzyme. The reduction of glucose by the AR-catalyzed polyol pathway has been linked to the development of secondary diabetic complications. Although treatment with AR inhibitors has been shown to prevent tissue injury in animal models of diabetes, the clinical efficacy of these drugs remains to be established. Recent studies suggest that glucose may be an incidental substrate of AR, which appears to be more adept in catalyzing the reduction of a wide range of aldehydes generated from lipid peroxidation. Moreover, inhibition of the enzyme has been shown to increase inflammation-induced vascular oxidative stress and prevent myocardial protection associated with the late phase of ischemic preconditioning. On the basis of these studies, several investigators have ascribed an important antioxidant role to the enzyme. Additionally, ongoing work indicates that AR is a critical component of intracellular signaling, and inhibition of the enzyme prevents high glucose-, cytokine-, or growth factor-induced activation of protein kinase C and nuclear factor--binding protein. Thus, treatment with AR inhibitors prevents vascular smooth muscle cell growth and endothelial cell apoptosis in culture and inflammation and restenosis in vivo. Additional studies indicate that the antioxidant and signaling roles of AR are interlinked and that AR regulates protein kinase C and nuclear factor-B via redox-sensitive mechanisms. These data underscore the need for reevaluating anti-AR interventions for the treatment of diabetic complications. Potentially, the development of newer drugs that selectively inhibit ARmediated glucose metabolism and signaling, without affecting aldehyde detoxification, may be useful in preventing inflammation associated with the development of diabetic complications, particularly micro- and macrovascular diseases.
The combination of Alpha Lipoic Acid with Evening Primrose Oil is more effctive than the mono therapy , this seems also be true for the combination with an Aldose Reductase Inhibitor :
Exp Diabesity Res. 2004 Apr-Jun;5(2):123-35.
Effect of fidarestat and alpha-lipoic acid on diabetes-induced epineurial arteriole vascular dysfunction.
In the present study, the authors examined whether treating streptozotocin-induced diabetic rats with the combination of alpha-lipoic acid and fidarestat, an aldose reductase inhibitor, can promote the formation of dihydrolipoic acid in diabetic animals and thereby enhance the efficacy of alpha-lipoic acid as monotherapy toward preventing diabetic vascular and neural dysfunction.
These studies suggest that combination therapy consisting of alpha-lipoic acid and fidarestat may be more efficacious in preventing diabetes-induced vascular and neural dysfunction in peripheral tissue compared to monotherapy, which requires higher doses to be equally effective. The effect of this combination therapy may in part be due to the increased production and/or level of dihydrolipoic acid.

Some had very bad side effects. One strategizes when one doesn't know the definitive answer. My strategy has been to minimise risk by adopting remedies based on foods that have been eaten by a sizeable population for a long period of time. Onions and purple perilla fit this definition.

He said someone called Lester Pasternak wrote a lot [quoted text clipped - 9 lines] > post is one abstract and a bunch of rhetoric (perhaps mild flaming -- if so, > sorry, but as many of you know numb feet are no fun). Hi there Bob,
As others have pointed out, there are quiet a few reasons why no-one had told you much about these kinds of treatments for diabetic neuropathy, one of the main ones being that quite a few of the "helps" are classified as supplements in the US and some other countries. Doctors may recommend them, but cannot prescribe them as medicines. It simply isn't legal (or safe in many cases).
Others are in the border-line area, for example the magnetic sole treatment. It is very difficult to do double-blind studies to determine if the benefits are from the placebo affect or genuine, medically sound and repeatable improvements. This particular problem, (amongst others), is discussed in this article from Medscape; http://www.medscape.com/viewprogram/3342 From Medscape General MedicineT Advances in Diabetes for the Millennium: New Treatments for Diabetic Neuropathies CME Author: Aaron I. Vinik, MD, PhD, FCP, FACP
" There are a number of treatments for neuropathy that are based on limited observations, for example, magnets. Although it is difficult to refute the power of magnetism, it is almost impossible to test the efficacy in a double-blind, placebo-controlled manner. One only has to use a compass to discover whether you are in the active or placebo group."
I suggest that you join Medscape, it is a free and reliable source of much information regarding studies and research on medicallly related matters. The biggest danger is from scams that purport to do all kinds of wonderful things, without any medically proven basis at all. Do seek out legitimate research and properly conducted scientific trials before trusting your body (or your wallet) to scientifically unsubstantiated claims. Including any advice from posters to this group, including me!
BUT do keep in mind that the experience of this group's sufferers supports legitimate medical advice that the best and primary help for treating neuropathy and/or other diabetic compications is to gain really good control of your blood glucose levels. That means an A1c under 6%, for example.
Here are a few sites and discussions by members of this group regarding helps for Diabetic Neurapathy that you may wish to read and consider.
http://www.medscape.com/viewarticle/496746 Supplemental Carnitine May Be Helpful in Diabetic Neuropathy Laurie Barclay, MD
http://www.medscape.com/viewarticle/491972 Aldose Reductase Inhibitor Decreases Nerve Sorbitol Accumulation
These extracts are taken from a post by Quentin Grady, a member of the group, and very knowledgable person regarding metabolic processes and dietary sources of some helpful substances. This quote discusses the role of aldose reductase inhibitors in reducing diabetic complication in the eyes, but applies generally to the same problem elsewhere in the body.
"1. Control blood glucose tightly.
2. Glucose in the eye can be converted to sorbitol by an enzyme called aldose reductase. (Re) ...... aldose reductase inhibitors. Onion is an excellent source of biologically available Quercetin. Quercetin saves the day and stops aldose reductase from converting glucose to Sorbitol. It doesn't matter if you fry up the onion in a pan on a camp fire, Quercetin can take it just don't pour it down the drain.
3. Taurine keeps sorbitol boxed up with osmotic pressure. Taurine is an amino acid found in fish especially shellfish and fish hearts etc, meat that hasn't been over-cooked. Eat some green lipped mussels or sardines. Steak that gallops onto your plate has more taurine than one grilled to death.
This next quote from Quentin I now repeat in total, since it bears on neuropathy in particular. Basically it is discussing the studies that indicate that combining Vit C with Gamma Linolenic Acid,(GLA), (found in Evening Primrose Oil (EPO), borage seed oil, or black current seed oil), on an empty stomach, may be of benefit.
"Evening Primrose Oil and Neuropathy
In general terms we know the GLA in evening primrose improves nerve conduction and GLA works better if used in conjunction with alpha lipoic acid. GLA is a little unusual for an omega-6 oil in that it is anti-inflammatory.
There is also a trick to making GLA more effective. When GLA is taken with Vit C without food the Vit C (ascorbic acid) and GLA form ascorbyl-GLA. Now I don't know if you can take GLA and Vit C on an empty stomach but I guess you could soon find out. Secondly I have no idea, apart from general principles, that GLA would work with gastroparesis in the same way it works with other neuropathy.
I've included an abstract which gives some reference to the increased efficacy of ascorbyl-GLA over GLA.

Studies in streptozotocin-induced diabetic rats show that nerve conduction velocity (NCV) and blood flow deficits are corrected by treatment with vasodilator drugs, with angiotensin II and endothelin-1 antagonists being particularly important. The AT1 antagonist ZD7155 also prevents diabetic deficits in regeneration following nerve damage, indicating that hypoperfusion is an important limitation for nerve repair. Metabolic changes include high polyol pathway flux, increased advanced glycosylation, elevated oxidative stress, and impaired omega-6 essential fatty acid metabolism. Aldose reductase inhibitors (ARIs) restore NCV via their effects on perfusion. ARI action probably depends on blocking the conversion of glucose to sorbitol, thus preventing depletion of vasa nervorum glutathione, an important endogenous free radical scavenger. Free radicals cause vascular endothelium damage and reduced nitric oxide vasodilation. Inhibition of advanced glycosylation and autoxidation (autoxidative glycosylation), major sources of free radicals, by aminoguanidine or transition metal chelators, corrects neurovascular dysfunction. Evening primrose oil supplies gamma-linolenic acid (GLA) to improve vasodilator eicosanoid synthesis in diabetes, correcting nerve blood flow and NCV deficits. Interactions between some of these mechanisms have therapeutic implications. Thus, combined ARI and evening primrose oil treatment produced a 10-fold amplification of NCV and blood flow responses. Similarly, GLA effects are markedly enhanced when given in combination with ascorbate as ascorbyl-GLA. Thus, metabolic abnormalities combine to produce deleterious changes in nerve perfusion that make a major contribution to the etiology of diabetic neuropathy. The potential importance of multi-action therapy is stressed.

Finally, there are indications that deficiencies in Vitamin B12 may be involved, and ingesting more of this member of the B group or it's sources "may" be helpful in helping to restore nerve function. This is because B12 is very much involved in nerve tissue health and growth generally.
One site that gives a fairly good overall discussion of Vitamin B12 can be found at; http://www.diet-and-health.net/Nutrients/Cobalamin.html Cobalamin (vitamin B12)
Good to see you getting into researching and finding your own solutions!
And regarding your question re intravenous vs oral treatments, many studies inject the substance of interest in order to be sure of the actual circulating amounts and their affect in the course of the study. Ingestion may not provide such accurate data, since people's digestion and absorbtion may vary, and cannot be relied on to produce reliable and repeatable data.

what is sorbitol and do I want it or not. and is taurine therefore a good guy? by keeping sorbital boxed up?
I have a tendency to eat shellfish with preference and prefer raw meat (no really), so I am good.
Is the taurine in all those things like red bull good for me too then?

Are all those propel waters and red bull any good as a supplement.
I know i feel better if I am drinking it (not just immediate impact, but for several days)

>> 3. Taurine keeps sorbitol boxed up with osmotic pressure. > >could you PLEASE explain this better. G'day G'day Marika,
Sure. Sorbitol is formed in the eye when the eye has been flooded with excess glucose. The flow of glucose into the eyes isn't regulated by insulin. If the level is high in the blood then it floods into the eye. In the cells in the eye it can be reduced to sorbitol.
Every NASTY pathway for damage to the eye features Sorbitol. If there was no sorbitol then the complex paths to nastiness would be blocked. The winning strategy is to prevent sorbitol formation in the eye.
Many reaction in the body are controlled by enzymes. Without enzymes the reaction slow to a virtual stop. The enzyme required to reduce glucose to sorbitol is called aldose reductase enzyme. That seems a bit confusing. How did aldose get into the picture?
Well glucose is an aldose sugar. Its just a classification thing. About half of all simple sugars are aldose sugars and the rest are ketose sugars. If the aldose enzyme is inhibited then sorbitol will not build up in the eye and lead to all that nastiness we wish to avoid. Quercetin, a substance found in a bioavailable form in onions etc happens to provide some inhibition of the aldose reductase enzyme.
Raw onions may make us weep on the outside but they protect our eyes from the inside. It doesn't matter whether the onion is cooked or not so long as we don't let the quercetin go down the drain if we boil them.
>what is sorbitol and do I want it or not. Sorbitol is a bad hat. We don't want it in places.
>and is taurine therefore a good guy? Taurine is a good guy.
>by keeping sorbital boxed up? It keeps the osmotic pressures normal in the eye. Osmotic pressure is what keep juicy things all nice and plump. Without the taurine leakage can occur. That is not good in itself. As I see it, it also helps prevent sorbitol spreading its influence.
Hope this explanation helps.

1000mg of taurine per 250ml can. A significant source. Too bad there's also 80mg of caffeine, about the same as two very large or very strong cups of coffee.
Somehow I doubt they'll be coming out with a caffeine-free version. First time I saw sugar free was last night, that's what drew my eye to the stuff in the first place.
Vicki ps - who is Lester Mosley?

Wow... And a sugar-free version! I actually like caffeine (it does not bother my BG's) so I think I might just try that!
Thanks!

We get sugar free V here. It has about 100 mg of caffeine and 700 mg of taurine per bottle.

Colleen - 01 Nov 2005 20:03 GMT I think it tastes awful. Chemical. Buy one can somewhere first to see if you like it.
I'll stick with eating right and drinking mega strong coffee. c
Today is roasting day at the coffee roaster a few blocks from our house. Neighborhood smells like one huge espresso! c

Hey, it's expensive! It's sold here only by the single can and there's a host of warnings about the caffeine. I get more than enough caffeine with all the black coffee I drink, I sure don't need more.
I don't even know if taurine is available as a supplement here. I've never had interest except to make sure cats are getting adequate amounts. They are, there's minimum amounts in commercial cat foods to ensure kitty's good health.
The first reference to taurine I remember was when my first cat was a kitten. I read an article about some stunned people that tried to feed their cats vegetarian diets. Can you imagine?!

Chris J. - 01 Nov 2005 23:16 GMT >I think it tastes awful. Chemical. Buy one can somewhere first to see if >you like it. I tried one of the non-sugar free (this was pre Dx!) and didn't like the taste of it either. I wasn't thinking about the taste, but the Taurine. I also like Caffeine on long drives, when hot coffee isn't an option, and I have one coming up soon. I will try just one, though, thanks!
