What do you think its overall benefits are then, if not a particular benefit or set of benefits?  True, it is methylated resveratrol, but then codeine is methylated morphine.  I tried using the pterostilbene Swanson's used to sell and there was no changein my blood sugar.

The heartwood of the malabar kino tree is the richest source of pterostilbene according to the literature.  Maybe there is some in the bark.  (Now if it ware a Malomar tree that would be interesting. ...)

The Chinese botanical extract industry is much more developed than  India's.  China's highly publicized problems have been in other industries.  Not to say there aren't problems possible anywhere, and you can easily purchase counterfeit botanicals if you aren't careful-- but even Japan's sophisticated pharmaceutical industry had major problems with tryptophan and eosinophilia.  Indian herbal and botanical products are problematic, specifically heavey metal poisoning.  Spice extracts are another matter, but for the most part they are much less developed than China, with a fraction of the capacity.   

If you want high purity pterostilbene- - and I have doubts about every supplement claiming to contain pterostilbene -- then try http://www.alexis- biochemicals. com/Pterostilben e.5+M5a8173466db .0.html  .  It's kind of pricey, but it's the real thing. Or you could methylate resveratrol in your kitchen: http://tinyurl. com/pc2g72


Some of the lab work with pterostilbene looks promising, but there is still a problem of getting enough of it at reasonable cost forlarge animal studies.  At this point, resveratrol appears to have many if not most of the same properties, and there are several sources of proven quality available, with or without quercetin or luteolin or piperine or Tween-80.

"Pterostilbene is a stilbenoid chemically related to resveratrol. It is thought to be the key compound found predominantly in blueberries (as well as grapes) that exhibit anti-cancer, anti-hypercholesterolemi a, anti-hypertriglyceridemi a properties, as well as fight off and reverse cognitive decline. It is believed that the compound also has anti-diabetic properties." I use it for its overall benefits, not for one thing in particular. I believe the extract I'm seeking comes from the bark of the tree, while the ayurvedic product I ordered comes from the heartwood, which is used for diabetes. For all I know, I'll receive sawdust. It's a joke saying China has superior products to India. India has a thriving pharmaceutical industry that supplies the US and the rest of the world with many of its generic drugs  I've never heard of any scandals involving impurities in Indian products, although lead is always a concern in natural products from Asia. Some ayurvedic products are intentionally high in lead as an active ingredient, which is horrific, but that's another story. Chinese failures in quality control are numerous and infamous. You appear very knowledgeable about the situation. Do you know of another place where I can buy pterostibene? --- On Fri, 5/8/09, Max Watt <maxwatt2002@ yahoo.com> wrote: From: Max Watt <maxwatt2002@ yahoo.com> Subject: Re: [resveratrol- users] Re: Pterostilbene and pTerinol To: resveratrol- users@yahoogroup s.com Date: Friday, May 8, 2009, 9:29 PM Lawrence J Lemer  said: I will eventually save up for the NuMedica purchase. As for Malabar Kino (pterocarpus marsupium) being endangered, I don't make political statements like boycotting when my health is at stake. ---- The problem is not political correctness, the problem is that even the Chinese government will not allow use of the tree, which limits the availability of high quality extracts. The Chinese supply the bulk of such extracts.  Lobsons gets theirs from India or other parts of South Asia, the purity may not be the best, and it has not been a big hit in the supplement market.  The samples I've seen appear to be mostly sawdust.  There may be some concentrated extract mixed with this. I certainly hope so.  It had no effect on parameters such as blood sugar or blood lipids when I tried it a few years ago.   Pterostilbene is not as well researched or tested as other stilbenes or polyphenols.  What particular benefit do you hope to derive from this as a supplement?
