Lobsons International, Inc markets pTerinol, pterocarpus marsupium extract,
which is 25% pure pterostilbene. I still have a small supply of Swanson's 30 mg.
capsules. NuMedica markets Resveratin, a Xymogen product, for about $60.00 for
60 62.5 mg capsules, with 15 mg of resveratrol added.

The website at Xymogen is a bit discouraging:

You have to order it through their doctor or another, presumably with additional
fees. They prohibit discounting.

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.

pTerinol will eventually be available through another source, as Lobson's is
anxious to sell their product and interest in pterostilbene is increasing.
Hopefully newer and better sources of
pterostilbene will be found or they'll start methylating resveratrol in a
laboratory. That's not a difficult process, but it might be very expensive,
given that resveratrol itself isn't cheap.

Other natural analogues of resveratrol exist and some are more powerful than the
original chemical. Chemists are synthesizing new analogues as we speak. The
future looks bright if we live long enough.
I'm 58.

Vitacost sells a 100 mg capsule at a very good price, by the way.

It makes it hard to get raw material. Other sources have too little to be worth
extracting, and there is no market driven motivation to go the chemical route.
