Phosphatidylserine supplement

Several studies in the past in Europe have evaluated the role of oral BC-phosphatidylserine administration in both animals and humans. In general, the results have shown positive benefits in terms of mind and memory enhancement. However, we need to keep a very important point in mind. The studies with phosphatidylserine have used bovine cortex as the source. Can we assume that the results with soy-derived phosphatidylserine would be similar?
   No, we can't. phosphatidylserine consists of serine attached to fatty acids. The serine molecule in phosphatidylserine found in cow brain is attached mostly to long chained polyunsaturated fatty acids such as DHA or AA (arachidonic acid). In addition, the cow brain extract is not pure phosphatidylserine. It most likely contains other brain components such as sphingolipids, sphingomyelins, and other brain constituents, which may have led to improvements in brain function. For obvious reasons--potential viruses present in cow brain --we should not be using the cow brain extract of phosphatidylserine. The phosphatidylserine in soy is basically serine attached to saturated on monounsaturated fatty acids, along with other fats from soy, which are chemically very different than the fats found in cow brain. Hence, we are basically comparing apples to oranges. It is medically and scientifically improper to use the results of studies done with phosphatidylserine from cow brain and thus claim that soy derived phosphatidylserine is also effective.

Mind Power Rx - Formulated by Ray Sahelian, M.D.

Mind Power Rx is a sophisticated cognitive formula. It combines a delicate balance of brain circulation agents and neurotransmitter precursors with powerful natural brain chemicals that support:

• Memory and Mood
• Mental clarity
• Concentration 
• Alertness & Focus


Why buy all the individual herbs and nutrients separately -- at great expense -- when you can buy this excellent combination? The herbs in Mind Power Rx include: Ashwagandha, Bacopa, Fo-Ti, Ginkgo biloba, Ginseng, Mucuna pruriens, and Reishi.  The nutrients and vitamins in Mind Power Rx include Acetyl-l-carnitine, Carnitine, Carnosine, Choline, DMAE, Inositol, Methylcobalamin, Pantothenic acid, Trimethylglycine, Tyrosine, and Vinpocetine.

   There have been two studies published recently using soy derived phosphatidylserine. The results are mixed. See below.

Phosphatidylserine Summary
There are so many other effective mind boosters that have good scientific support that phosphatidylserine, at this time, is low on my list, particularly since it is also very expensive. I like several other Mind Boosters including acetyl-l-carnitine, DMAE, cdp-choline, and SAM-e.

Phosphatidylserine and glinkgo biloba research
Acute cognitive effects of standardised Ginkgo biloba extract complexed with phosphatidylserine.
Hum Psychopharmacol. 2007 Jun;22(4):199-210. Kennedy DO, Haskell CF, Mauri PL, Scholey AB. Human Cognitive Neuroscience Unit, Division of Psychology, University of Northumbria, UK.
The current study aimed to assess the comparative cognitive and mood effects of a low dose of ginkgo biloba extract and products complexing the same extract with either phosphatidylserine or phosphatidylcholine. Twenty-eight healthy young participants received 120 mg ginkgo biloba extract, 120 mg ginkgo biloba extract complexed with phosphatidylserine (Virtiva), 120 mg ginkgo biloba extract complexed with phosphatidylcholine and a matching placebo, on separate days 7 days apart. In keeping with previous research utilising the same methodology, 120 mg of ginkgo biloba extract was not associated with markedly improved performance on the primary outcomes. However, administration of ginkgo biloba extract complexed with phosphatidylserine resulted both in improved secondary memory performance and significantly increased speed of memory task performance across all of the post-dose testing sessions. Complexation with phosphatidylserine appears to potentiate the cognitive effects associated with a low dose of ginkgo biloba extract.
