Great Stuff - Overlooked for Sleep

Posted by mozzer on Jun 23, 2015

My experience with PS is that 300mg or 400mg before bed with some magnesium is a powerful sleep stack. PS is also a well known brain health ingredient, take with fish oil, ALCAR, bacopa, or Alpha-GPC. I use 1 cap at a time during the day but in combination with DHA and Alpha GPC, I find myself much more verbal and upbeat.

very good

Posted by Reviewer2525926 on Sep 04, 2014

I use this sometimes when I'm very tired or stressed, because it makes me much more calmer, balanced and it clears my head. However, it's too expensive for me to take 2-3 times a day, which I would really like to do. It's really very good.

I opened the capsule tried the contents. It tasted rancid! I thought I would finish then as they were expensive. The next time the taste was very rancid and bitter. In the bin. Other brands are good. NOT Doctors Best!
