iHerb Customer Reviews

Great for lowering cortisol!

Posted by iHerb Customer on Dec 18, 2017 | Verified Purchase

I found this to be very helpful for lowering cortisol, especially before bed! Brings me nice sound sleep. (Note: cortisol that is too high or too low can both cause insomnia, so it's often a good idea to get a saliva cortisol test to see what your personal cortisol levels are. )

Thanks for your feedback!

Great product

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

My doctor recommended I take PS, and I tried this Jarrow brand (as they are the best!) It beat out the brand my doctor recommended - and digests easily. Very happy with this formula.

Thanks for your feedback!

It's good for me

Posted by iHerb Customer on Aug 27, 2017 | Verified Purchase

I take it with breakfast and lunch for around one month. And it is quite good for me because I feel that I think or calculate faster.

Thanks for your feedback!

brain fog be gone!

Posted by iHerb Customer on Aug 14, 2017 | Verified Purchase

I began having brain fog more and more regularly and hated that coffee didn't really help. I do feel quite a bit of difference after using this for a month. It really does help with mental clarity. I recently bought my 2nd bottle...I recommend it. No side effects that I can tell either.

Thanks for your feedback!
