priced well, and supposed to help with cognition. I haven't noticed much of a difference, I suspect it is very subtle. great ingredients, not much filler. good size for the price and jarrow is a dependable brand that has consistent quality. good dosage, I like that its soft gel so easier to swallow.

Nothing I buy ever works, but this one did!! Due to my PTSD, I've always had high cortisol levels, and I'm prone to stress and the physical and emotional consequences of being on high alert all of the time. I saw a significant increase in my energy levels, with no dips. I wake up at 6 a.m. and go to bed at 10 p.m. with no energy dips, I sleep well all night, and I am more calmer overall. With my time, I can accomplish a lot more. People with elevated cortisol levels owing to mental illness, high stress lives, or other factors should take this supplement.

This has definitely helped my sleep, gave me some weird dreams at the start but that is due to your body getting into deeper REM sleep. Also it did give me a slight stomach upset but that went away. I did start on a big dose of 300mg with a meal at night. Bottle size makes it last longer, no after taste. This is a high quality supplement.

Great for brain health. I just feel sharper when I have two of those first thing in the morning. If I go three days without taking them I can tell the difference. Maybe its placebo, but then if so the placebo effect has been working for well over 3 years and this item is on my subscribe and save list.

PS100 contains a high quality ingredient, Phosphatidylserine. The major benefit of this ingredient is in its ability to improve mental performance, attention and memory. It's very important that FDA approved claims that state Phosphatidylserine “may reduce the risk of dementia and cognitive dysfunction in the elderly. The product's taste is good, the dosage and size of PS100 is as required.

If you are anxious and lose your calm all the time - these pills are for you. From the first sight it seems like they have no effect. But then you suddenly realize, that things that made you nuts are ok now, and you are not so nervous and sleep better. Recommend

I take this dietary supplement almost on a regular basis. I can take a break for a maximum of 2 months. With him, you somehow perceive criticism more easily, you react more calmly to stressful situations. Working capacity increases, attention is switched from subject to subject faster. As for me, the drug has a cumulative effect. I recommend

I think these are excellent for your memory and brain power. It has helped me to concentrate more and retain information. Would recommend to anyone in an executive role or over 65s.
