Improved sleep quality
52 people found this helpful
An excellent working drug! Phosphatidylserine enhances mental concentration, memory, mood, and sleep. I take one capsule daily with ubiquinone and benfotiamine, along with amino acids and B vitamins to restore my nervous system. They are small, soft capsules, easy to swallow. The drug clearly works; my sleep quality improved significantly. Previously, I needed 8-9 hours for a good night's sleep, but now 6-7 hours suffices. I'm very pleased with the result and will continue purchasing it. This product truly deserves attention. Stay healthy!

Mental clarity achieved

This has genuinely helped me sleep better while also lowering my cortisol levels in the evening. It brings mental clarity, too. Although it's somewhat pricey, I find IHerb offers the most reasonable prices for it.

Better sleep quality
14 people found this helpful
After switching to PS-100 upon a herbalist's suggestion due to concerns with Ginkgo Biloba, I now enjoy the same mental clarity and, notably, better sleep! It's an unexpected bonus, as I was unaware of this benefit initially. I've been taking it for around three months and have noticed significant changes.

Lowered cortisol levels
9 people found this helpful
I've been using this for improved sleep and noticed a difference in lowering my cortisol levels. It’s essential to take at least 200 mg to see results. I’m gradually increasing it to 300 mg. I strongly recommend this to anyone seeking better quality sleep while avoiding electronic devices before bed.

Deep undisturbed sleep
5 people found this helpful
Previously, I tried a soy-free version of phosphatidylserine by Jarrow brand. Taking it before bed provided a deeply restorative sleep reminiscent of childhood—no interruptions or dreams. I’m unsure about its impact on memory, but it indeed promotes restful sleep and enhances mood. Be cautious with timing, as it can induce sluggishness if taken too late.

Significant sleep improvement
1 people found this helpful
Helps reduce cortisol and improve sleep! When combined with basil and L-theanine, it soothes and enhances the deep phase of sleep. Since drinking 300 mg three times a day, my sleep with phosphatidylserine has significantly improved, apparently really reducing evening cortisol.

I take it in the evening, and it certainly assists my mind in relaxing and ceasing to contemplate all the things I must do. I get to sleep quicker and enjoy better sleep throughout the night.

Sleep regulation
1 people found this helpful
This means for regulating sleep was prescribed by my nutritionist to take 1 tablet an hour before bedtime. It effectively helps with sleep regulation, as I stopped taking melatonin, which previously caused disruptions.
