I want to try this for suppressing cortisol. For those of you who have used this for awhile, do you still think it’s a worwhile supplement? What is the most economical source? Seems like it would make a great stack with Powerdrive. Thanks.
If you have Trader Joe’s in your area you can buy 60 tablets of PS 100 (100 mg phosphatidylserine with 188 mg calcium) for around $23. Since my father is elderly and deteriorated mentally I used it for a long time because of its touted properties to maintain mental acuity but I’m not sure how well it blocked cortisol. I do use PowerDrive every day and feel it helps me mentally so I stopped using PS100 for economic reasons.
I would be interested to hear from anyone who has performed or seen a controlled study involving phosphatidylserine.
I believe Poliquin reccomended taking PS at 800mg per day.
