The formulation is sold under the Natural Factors– brand. This is a company with over 60 years of experience. The producer claims to use only raw materials raised on their certified-organic farmlands located somewhere in North America. The soil quality is also one of the company–s best assets, as they are abundant in natural organic matter, making the use of fertilizers unnecessary.
Natural Factors PS Phosphatidylserine is advertised to provide a highly absorbable form of PS extracted from sunflower lecithin. This is an herbal remedy, unlike the first PS supplements that used animal based Phosphatidylserine that was extracted from cows– brain cells. The use of animal PS has been banned many years ago due to a concern of mad-cow–s disease transmission to humans. Natural Factors formula features 100mg of Phosphatidylserine in a soy-free product. Soy is known as a highly allergenic product, so this is probably why the company chose sunflower as the source of their raw material. The sunflower lecithin used comes from a non-GMO source.
PS supplements are very popular at this time, particularly because cognitive decline affects a large part of the elderly population. Alzheimer–s is one form of cognitive decline that manifests through irreversible memory impairment and finding an effective treatment has become a major concern of medical doctors all over the world. Despite these efforts, so far results are not optimistic.
Natural Factors PS Phosphatidylserine , contains the following ingredients: Natural Factors PS Phosphatidylserine contains the following ingredients: (Helianthus annuus) (seed), and Phosphatidylserine. Also contains naturally occurring Phosphatidylcholine (PC), Phosphatidylinositol (PI), and Phosphatidylethanolamine (PE).
PS is the main active chemical in this supplement. A few other active nutrients have resulted from the manufacturing process such as: Phosphatidylcholine, Phosphatidylinositol, Phosphatidylethanolamine, but the main focus remains on Phosphatidylserine. This chemical is naturally occurring in all human cell membranes, including brain cells. The scope of each membrane is to filter the nutrients and facilitate proper cell communication and cell growth.
In time, PS levels within brain cells decrease and this is considered one of the main reasons of memory lapses occurrence and decline of short-term memory. Without the right amount of PS (among other nutrients) the neurons (brain cells) are not able to communicate correctly, and some information may be lost along the way. Scientists believe that by restoring PS levels they will manage to reduce memory loss and restore optimal transmission between neurons.
The major concern with dietary supplements is that they are often not scientifically proven. It is also the case of PS based products where clinical trials are not considered to be conducted in a manner that is consistent with generally recognized scientific procedures. FDA does not approve PS products as standard treatments of cognitive dysfunction including Alzheimer–s disease. However we decided to consult consumer testimonials available online on the web-sites of the retailers currently selling the formula. While they are not very numerous (1-2 hundred reviews), most of them reflect the positive outcomes experienced by taking this supplement. Satisfied users report improved sleeping patterns, reduced brain fogginess, enhanced focus capacity, and reduced Cortisol build-up (in people who suffer from certain conditions).

- The formula is not scientifically proven as effective through specific clinical trials
- PS is a controversial substance and the herbal sourced PS are not as researched as animal based Phosphatidylserine
The main problem when it comes to nutritional supplement like Natural Factors PS Phosphatidylserine is the lack of clinical evidence. To some extent, researchers have recognized the benefits of PS and its role in brain cell communication, but synthetic forms such as this are not always considered the best source for replenishing the levels of PS within the body.
Most of the scientists are skeptic that many of the chemicals used within these supplements are not able to cross the blood brain barrier, making them ineffective brain supplements. At this time researchers are fervently looking for Alzheimer–s disease cures, a lethal neurodegenerative condition that affects memory of the elder, making them nonfunctional human beings and ending their lives too early.
PS is used in the treatment also, but results are inconsistent. The improvements noticed in some cases proved to be only of short-term and only on patients suffering from mild symptoms. However, healthy individuals who have used PS supplements seem to have noticed improvements in various cognitive areas, so it might not be a totally useless approach in maintaining cognitive health in generally healthy people.
