Soybean-Derived vs. Bovine-Derived Phosphatidylserine

Phosphatidylserine is another supplement that has received a lot of attention in the past few years. There are a number of helpful benefits associated with it including an improved memory, mood, and a number of other cognitive functions. However, there seems to be a debate right now over which type of source makes for the best supplement. The two choices are soybean or bovine (cow) derived Phosphatidylserine. In order to make an informed decision, it is helpful to first know the benefits of this supplement.

What Is Phosphatidylserine?

This supplement is actually a natural ingredient or component of the membranes of living cells. This substance is found in the cell membrane of neurons (brain cells). Phosphatidylserine comprises as much as 10 percent of the lipid content of these cells. While it is possible to obtain this ingredient from food, we do not actually get very much this way. Average daily consumption is around 100 to 150 mg.

Phosphatidylserine Benefits:

This supplement is thought to regulate how brain cells work and process information. This is done by these membranes actually controlling which nutrients are used by the brain and which are passed out as waste products.

Another excellent benefit of this supplement is that it helps to improve communication between the various brain cells and hemispheres. This communication is thought to occur by increasing the number of receptors and increasing the production of Acetylcholine, a powerful neurotransmitter that plays a key role in memory formation, learning, and other cognitive functions.

While taking this supplement, memory is enhanced and so is the general speed of recall. Many users also report having much improved clarity and speed of thought. Attention span is increased and so are the abilities to concentrate and focus.

Phosphatidylserine Supplements: Bovine Or Soybean Derived?

In the past, most Phosphatidylserine was produced from bovine or cow sources. The raw ingredients were actually extracted from the brains of cows. Currently, most of the product on the market is soybean derived due to the FDA concerns about things like mad cow disease and other health issues. Almost all of the studies indicate the excellent benefits of this supplement were performed a few years ago using bovine derived sources.

There are some differences between the two sources. Bovine derived is usually attached to long chained polyunsaturated fatty acids (DHA or AA). The soybean derived variety is usually attached to saturated or monounsaturated fatty acids. While it does follow that many of the benefits should be similar, new studies need to be performed.

Using Nootropics for Motivation

Nootropic supplements are finding more and more uses in the area of brain enhancement. The term nootropic was originally coined in 1972 by Dr. Corneliu E. Giurgea and is derived from the Greek word “mind” and “to turn”- a fitting description of the alteration that these supplements can accomplish in the brain.

Nootropics can enhance memory, motivation, cognition, attention, alertness and more. Although the effect of each nootropics can help boost motivationsupplement will vary from person to person, there is always a common denominator.
The majority of the nootropics produce some form of motivation but let’s take a look at a few that have been especially noted to increase motivation:


Sulbutiamine is a derivative of Vitamin B1. Because of its ability to cross the blood barrier faster than Vitamin B1, this supplement is stronger in terms of effects. Like thiamine, sulbutiamine works by aiding in the biosynthesis of acetylcholine and GABA but has a faster absorption rate.

Benefits of sulbutiamine include improved memory and stimulation. It has been used by athletes as a legal performance enhancer. Sulbutiamine causes upregulation of the reticular-activating system in the brain, which is the center of arousal and motivation.

Dosage of sulbutiamine is reported to be 12.5mg/kg although this may vary. Side effects include nausea, skin rash, headaches and anxiety. Thankfully there are nootropics for anxiety.


Aniracetam is one of the most common racetams and is a cognitive enhancer known to enhance memory and concentration. It works by increasing communication between the left and right sides of the brain. This boost increases creativity, perception, and more. This supplement stimulates the function of neuronal receptors by means of glutamic acid which aids in the memorization process.

Aniracetam is usually stacked with choline in order to reduce the side effects that commonly occur with the use of aniracetam. Dosage of aniracetam is 1500mg taken twice a day in 750mg doses.


Vinpocetine is a cognitive enhancer that works by increasing the blood circulation in the brain. This increase in turn increases cellular efficiency. Additional benefits of vinpocetine include enhanced alertness and mood enhancement. Standard dosage of vinpocetine is 10mg taken three times a day.


When it comes to the search for nootropics for motivation, there are no hard rules. The fact remains that everyone reacts differently. It is noteworthy that supplements that have been considered to be good motivators, such as caffeine and amphetamines, can in fact have the opposite effect. According to a report, these stimulants do not actually raise motivation levels especially in individuals who are motivated.

With this in mind, one should carefully consider the nootropics taken for motivation—making the wrong choice can have negative effects. The aforementioned nootropics are what have been recommended by many.
