Clear and focused
I love the way this product helps me to be clear headed, focused and energized without any side effects during the day, but at night I am having a hard time sleeping. I tried taking it at different times, morning and at night, and it didn't help the insomnia issue, and I only took one pill per day. Maybe this supplement affects all people differently because other reviews say it helps them to sleep well. 🤷🏻♀️ Overall, I really like the feeling it gives me during the day. I will just have to take a mild sleep aid for at nighttime when I choose to take this product.

Life-Changing!!!
Update: I found that this is more effective for me when I take it at the same time as I take my DHA Fish Oil capsule. I am almost finished with my third bottle of NOW Phosphatidyl Serine (120 capsules each). I have always been a naturally high-strung person, and I have a tendency to internalize stress. I have tested as having very high cortisol, accompanied by low progesterone (called the "Progesterone Steal," by my Anatomy and Physiology Professor). I strongly suspect this is related to my fertility problems (dubbed "unexplained infertility by the clinic). Unfortunately, being a bucket of stress is not conducive to health in any area of life. Since I started taking this product, my stress levels are absolutely manageable. This is not a subtle effect; it's quite obvious when I have forgotten to take my pill (morning and night, and occasionally lunch time if it's a particularly stressful day). I become extremely edgy, and much more likely to snap at anything that goes wrong. This little pill has helped my marriage, and helped me to be a better mother. My husband has remarked multiple times on the difference in my mood between when I have taken a pill and when I haven't. I have also started ovulating again. (I do also take NOW DHA/EPA, along with my raw prenatal vitamins and folate.) If you have irritability and adrenaline issues, and trouble dealing with stress, I highly recommend you give this a try!

A good product, but needs to be taken with DHA or it will not be effective.
I started taking PS (phosphatydil serine) because I'd been suffering from a range of symptoms including brain fog, anxiety, confusion and depression, following an injury and a high stress event in my life. The stress apparently made my stress levels and cortisol levels shoot through the roof, leaving me stuck in "fight or flight" mode for several weeks. The first brand I tried was NOW. It was almost immediately helpful, particularly once I combined it with fish and krill oil. I believe this is because it's helped reign in my cortisol levels. It's one of the more effective brands, at least for me. More thoughts: 1) NOW has several types of PS: soy based, sunflower seed based, with choline/inositol, or with ginko biloba. The type I take is soy based and has added choline/inositol. In principle I don't like the idea of taking a soy based product. But for me, soy based PS has been more effective than the sunflower based PS products I've tried. 2) I have not found NOW PS, or any other brand of "pure PS," to be effective when taken alone. PS works best when taken with fish oil or krill oil which are high in DHA. This makes sense because the types of PS which showed such benefits in lab test years ago were extracted from cow's brains, which are, like human brains, naturally high in DHA. PS and DHA need to be taken at the same time. 4) Another PS product I like and recommend is the one called Sharpthought from Country Life --- a type of PS which has been complexed with DHA. It's more expensive than plain PS, but you don't have to take it with fish or krill, so it's not as much pricier as it might seem. See my review of it, also on Amazon. Good luck. If you're looking for a natural product to help reduce your cortisol levels, I hope you find something that helps.

I would love to hear what dose people are taking!
I have just started taking ONE 100 mg capsule about an hour before bed about a week ago as per a suggestion from my doctor. The first couple of nights I slept wonderfully and I had been having some difficultly getting a good nights sleep prior to that. I seemed to have more mental clarity as well. I felt like I had more energy after sleeping so well. However, I have not continued to feel as great as I did the first 1-3 days. I would love to hear how many capsules other people take that have success with this product. I am wondering about taking more than 1 capsule, as this product seems to have a stimulant like effect on people with mental clarity and energy, yet I am taking it before bed for better sleep. Most of the reviews show people are happy with this and it is helping them, but not many tell how many capsules they are taking for the results they have had.

Not labeled properly -- contains choline
I love NOW as a company, and use a lot of their products. I usually purchase ps100 by jarrow to help mitigate cortisol levels before bed during periods where fasting may be integrated into my health routine. I bought these instead, only to realize AFTER opening the bottle that it contains 100mg choline per serving -- indicated nowhere on the front label. While PS at 300-400mg before bed has a positive effect on sleep, high doses of choline before bed certainly does not, actually the opposite. I can't use these, wasted money.
