My mother's memory has improved.

Thanks for your feedback!

Jarrow's a reliable brand

Posted by iHerb Customer on March 7 2018 | Verified Purchase

Recommended to me by a retired nurse, phosphatidyl-l-serine is not always easy to purchase, due to its cost. Holland and Barratt used to stock it but discontinued it in the UK. The soft-gels are particularly useful to me, for giving to my mother who has dementia. The gel capsules when pierced allow me to put the contents inside a chocolate, and get them down her! She has recovered to some extent from a stroke suffered at the age of 83 and her cognition improved. I think the help from the Jarrow capsules and constant attention from me, have helped her regain some of her capacity for speech and thought. She's now 90! I take the capsules myself as an insurance policy.

It is most difficult when your partner has Alzheimers, and you live in Australia but watch all the cutting edge information available on the Documentary Series in the U.S.A. You go to your GP and they think you are mad. Not knowing or not wanting to know about the cutting edge products or information, so you re-watch the series and take notes of all the great breakthroughs and try to implement yourself. Being a lay person and self diagnosing is probably the worst thing you can do. But what do you do when your loved one is on a health food regime not sick or taking any prescription meds exercise well etc. My husband is taking a multitude of "brain" meds, and I would love to tell you that Phosphatidylserine "PS100" by Jarrow is just the best thing since sliced bread, but I cannot. I know that the mix of health food type meds he is on now are halting the progression of the disease. He has been taking Phosphatidylserine now for over 2 years along with others. I would not remove it from his meds and other friends who have tried it (without Alzheimers ) said they were much sharper. It is a good product.

Thanks for your feedback!

Great for lowering cortisol!

Posted by iHerb Customer on December 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 September 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.
