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?
