sed ALC, which is a patented conversion of one of my favorite nutrients, l-carnitine. I'll bet l-carnitine is just as effective, but the funds for studying this somewhat cheaper nutrient in side-by-side testing are not available, so there's no proof. ALC has more advertising behind it, but I'm not yet convinced it has advantages over l-carnitine. We're almost done, I promise (though you may have been done long ago). It's worth touching on just a few last agents. The first is actually a hormone, called pregnenolone, which has been studied pretty extensively, along with another hormone called DHEA, concerning the ability of these two agents to modulate chemical reactions involved in the storage and retrieval of memory. I tend to walk softly on hormones, as they can be powerful agents and can have a multitude of chores to do within the body. When I use them I like to use the ones that are farthest up the line of the hormone system, so the body has more chances to decide how to use the downstream products. For that reason I tend to prefer pregnenolone, if I had to choose, and I'd stay with low doses, like 3 milligrams every day to every other day, and only in those over 50. You should talk with your doc on this subject, as hormones can be wonderful agents, but they should be monitored. Vinpocetine is a natural extract from the periwinkle plant. There are many research papers, mostly from Europe, on both animals and humans concerning this product's ability to enhance memory function by affecting both microcirculation and production of ATP, the molecule that provides increased energy to cells. Most studies showed levels of up to 40 milligrams twice daily gave subjects the most improvement in both storing and recalling lists, well above placebo results, and with a high degree of safety (but of course ask your doc). Remember (!) that "acetylcholinesterase inhibitor" term? The last agent (I promise!) is a new one that's received a fair amount of...
