Great suff -works for me

Posted by iHerb Customer on Dec 15, 2017 | Verified Purchase

i find that this product definitely sharpens my brain after only one week of taking it. I am 67 and getting a bit vague but taking this puts me back on top cognitive form.

Thanks for your feedback!

Great Stuff - Overlooked for Sleep

Posted by mozzer on Jun 23, 2015 | Verified Purchase

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.
