Jarrow Formulas100 mg Phosphatidylserine (PS 100), Supports Brain Health, Soy Free, White, 60 Count

I like this supplement. It's very hard to tell when a supplement is working often times but I feel like with this one I can tell. I feel like I'm a little more focused and my memory is a little more on point when I take this. I like it.

These are magic pills. My family has tried multiple supplements for sleep aids and nothing ever works. But if I take 1-2 of these about an hour before bedtime I fall asleep well and stay asleep.

I just started the product but immediately could tell the sofríela were melted. A solid clump. May consider alternate product.

I have taken PS100 for years in hopes of reducing brain fog. I find Lions Mane to be far superior and have stopped taking this supplement. If I notice a decline in my acuity after stopping I will go back on it and update my review.

This product helps me to retain information.

This product should be taken with curcumin during the day and one taken by itself at night—so told to me in a health consultation.

This product is the best in the market.

No bad taste, never received a bad batch from Amazon. Have purchased many times. Excellent price for this product.

Great product

There are a ton of studies on this supplement and none show any major side effects. Taking this - I feel like I'm snorting some hard illegal drugs. My heart races and my hands get cold and clammy. I don't know what's in this bottle, but it's not the supplement as advertised.

I need to start. to do something for my memory. I don't want to get dementia.

Works well to help manage ADHD symptoms

as advertised

Item was delivered with all capsules clumped together in the plastic bottle. Exposed to high heat.

It seems to work for me
