NOW FoodsSupplements, Phosphatidyl Serine 100 mg with Phospholipid compound derived from Soy Lecithin, 120 Veg Capsules

Highly effective without side effects. Have reordered several times. A very natural your own energy type of improvement. Vitamin b1 (bentofimine). Also effective if you get the dose right. This is easier though. Creatine, NMN, various anti oxidants, various neurotransmitter precursors didn’t work well for me.

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.

This item was all that I expected it to be. Takes a little time, but it works.

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.

Nice

I find myself remembering better when I take this.

Seems to help out with stress, but seems to be out of stock often.

A highly trusted company. Worth the cost whatever the individual product.
