Prophets, thanks for posting that. Hopefully more research will follow.
Resv, at least in the 200-300mg range that I have tried it, did nothing to lower my BG. Other things I take (and do) can have an effect but thats another topic. Metformin does seems to work a little for me, but nothing drastic. So I am not sure how I will proceed yet, but a few things to note... I do recall reading a few years back that Metformin was found to lower risk of Alzheimer’s even without the addition of exogenous insulin. I'll see if I can find anything to back that up, but a quick Google finds:
http://www.foxnews.c...,203995,00.htmlDonald Miller, ScD from Boston University School of Public Health and colleagues report that people with diabetes treated with these medications [TDZs -yeah like the ones implicated in raising heart attack risks] had lower rates of Alzheimer’s disease than counterparts taking insulin. In fact, there were almost 20% fewer new cases of Alzheimer’s among people taking thiazolidinediones compared with people who took insulin. Similar results were found in a separate comparison between thiazolidinediones users and people starting Glucophage, another drug used to treat diabetes.
So not exactly what I'm looking for, but if that is true,
AND if the summation from the authors of the study you posted are also correct....
http://www.pnas.org/...106.short?rss=1Although insulin and metformin display opposing effects on Aβ generation, in combined use, metformin enhances insulin's effect in reducing Aβ levels. Our findings suggest a potentially harmful consequence of this widely prescribed antidiabetic drug when used as a monotherapy in elderly diabetic patients.
http://www.medscape....warticle/589647The upregulation of beta-amyloid generation by metformin in animal models of AD occurred at steady-state plasma levels at and even below those reported in diabetic patients.
Metformin is an insulin-sensitizing drug, and the researchers found that giving it together with insulin added to insulin's known ability to reduce beta-amyloid generation.
"Our data suggest that the potentially deleterious effects of metformin to AD patients may be avoided by using it in combination with insulin; the combination may result in a beneficial effect in treating both type 2 [diabetes mellitus] and in mitigating AD progression," the researchers write.
AD expert Michal S. Beeri, MD, from the Mount Sinai School of Medicine, in New York, told Medscape Psychiatry, "The report by Chen is very interesting and consistent with a study from our group showing that brains of diabetics who, when alive, received combination therapy (ie, insulin plus an insulin sensitizer) had 80% less neuritic plaques (1 of the hallmark lesions of AD).
Then it would seem likely/possible to me that if you already have higher levels of
endogenous insulin due to insulin resistance, common in type II diabetes, then the risk could be mitigated or at least lowered.
I have slightly elevated fasting insulin, and I'm taking Metformin to lower BG and for the possible cancer risk reduction (which is indeed elevated given my age, previous live style, and family history). Others, like gregandbeaker, that are using it with insulin injections, and perhaps those that know their ApoE ε4 allele status, might also find it worth the risk for now until more is known. Without any of those factors, and normal to low insulin, I likely would just drop it until more is known.
