A question we get in the pharmacy is what is Phosphatidylserine(PS) used for? First it's a long word to pronounce (say it 3 times fast)- and secondly its not well know to a lot of patients that we talk to. Phosphatidylserine (PS) is a member of the membrane phospholipids that can be found in the brain. So much so that several studies have done research to see if it helps with memory, stress, and other functions your brain has a role in. Imagine taking something every day and realizing you have a better memory, have less stress, and are sleeping a lot better! Several clinicians and scientists thought the same things and several studies have been undergoing way. One study I found interesting which you can find here ( http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966935/) and a interesting fact they found which I will post here.--- "However, in the subjects with relatively low score at baseline, the memory scores in PS treated groups were significantly increased against the baseline, while those of placebo group remained unchanged. This study showed that memory scores on testing data show it improved. Another studies shows improvement in emotional states (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4271139/) Personally I have seen patients transform their lives with this supplement. They feel less anxious, less stressed and are able to rest. Our brand of Phosphatidylserine is derived from sunflowers, the traditional extraction is taken from soybean. Stop by and we will be glad to give you more information or talk to you about your other supplement needs.
