Phosphatidylserine soy version from doctor’s best brand.
Specifically mentioning the brand as other brand version may not give same cognitive results. It basically improves working memory. Especially it help to hold information in mind while doing activities thus it help to better ignore distractions. If test with working memory games like dual n back you can get a better score.
OCD is basically due to low working memory. For example If do one activity or think about something mind goes blank for every other thought, urge etc. So if some distraction come then that distraction disrupts the main activity and need to restart, redo and appear like OCD compulsion. Not every OCD is due to low working memory but if its the case then this supplement can be helpful to better manage OCD issues.
Its a stimulating supplement so need to take it earlier part of the day to avoid affecting night sleep.
