As with many of these highly priced “memory enhancing” products, claims for Procera AVH are based on flimsy folkloric anecdotes from ancient Chinese medicine and extrapolation from incomplete and inconclusive scientific studies.
The main “memory enhancing” components appear to be Vinpocetine, Huperzine A and acetyl-l-carnitine
This is found in any normal diet (including vegetarian). The highest amounts are found in red meat and dairy products although legumes, nuts, cereals and many fruits contain significant amounts. The precursor carnitine is biosynthesised primarily in the liver and kidneys from the amino acids lysine or methionine. A normal diet should give more than enough of this material without the need for supplements.
This is an alkaloid extracted from the periwinkle plant, Vinca minor. In 2003 a clinical trial on "older adults with memory problems" produced inconclusive results. Since vinpocetine is related to other Vinca alkaloids, Vincristine and Vinblastine, that are powerful anti-cancer agents which impair formation of microtubules, there is suspicion that this drug may have similar effects and should be used with extreme caution.
Huperzine A is an alkaloid found in the plant firmoss, Huperzia serrata. Although it has been used in China for centuries for the treatment of swelling, fever and blood disorders, there are no studies in the West showing memory enhancement. Clinical studies in China on early stage treatment of Alzheimer's disease show that huperzine A is comparably effective to the drugs currently on the market.
I’ve seen no evidence to suggest that Procera AVH can “detoxify” your brain any better than a glass of clean water! In fact, taking chemicals that go directly to the brain will introduce "toxins" to the brain. This claim is plain silly!
My conclusion about Procera AVH is that this product may have a marginal effect on memory but, like you, I very much doubt the claims made by the manufacturers.
