I’ve been taking Phosphatidyl Serine, 400 mg, 120 Capsules for a few weeks now, and I can definitely notice the benefits. My mental clarity and focus have improved, and I feel more alert throughout the day. It’s especially helpful when I need to concentrate for long hours or manage stress.

Strong

This is really strong supplement and you might feel over excitement as a side effect. Try to take only one capsule a day for a week and only if it feels ok take two a day.

I notice some clear benefits - these supplements are calming and bring down cortisol levels. And I tend to trust this brand’s quality and have yet to be disappointed. Also, there’s is no issue with the size of the capsules. What I do want to warn, though, is that these can lower your immunity so keep that in mind when you’re figuring out the dosage. Less is more here.

Very good and cheap

It is a very good product and the price is very affordable. From scientific research the dosage you need to take 3 pills per day, size is not so small so fi you have a problem with big caps maybe could be a problem but the product is a very great one and, compare with prices on the market is one of the best deal one can afford! Benefit are clearly states by research and has no taste. Ingredient are ok and there is anything bad inside. Very very good quality product and strongly suggested.

Stress Stopper!

If you go through rough patches in life or need something that helps take the edge off, you should give PSP a try. Although I would say even half a dose is pretty effective, and the full 400 mg dose may sedate you a bit too much. Trial and error!

Brain health

I really like Nutricost brand. They are on the cutting edge of nutritional science. Do your own research though. The dosage giving 3 months makes it quality purchase. Quality ingredients take it to the next level. The benefits of brain health are immense. Size of caps easy to swallow.

Vitamin C mega dose

I am trying vitamin c mega dose and i found 500mg dosage and size quite convenient as I prefer to spread it throughout the day as it is supposed to be of greater benefit than taking a higher dosage one or two times a day. It is a good quality product at a very reasonable price.

Great for focus and mental clarity!

Phosphatidylserine helps improve my focus, memory, and overall mental clarity, especially during busy or stressful days. The capsules are easy to take and gentle on the stomach. I appreciate that it’s made with quality ingredients and delivers consistent results. A great supplement for supporting brain health and cognitive performance naturally!

Stress reduction

Phosphatidylserine is a common phospholipid that regulates cortisol, which basically means that it helps managing stress. I work in a high pace office job and this supplement is part of my nervous system support. Great product, perfect value for the price. Ingredient list is clean, nutricost makes great quality products. One bottle is enough for 2-4 months.

Great

I already tried this ingredient before in another supplement, where one capsule was half the dosage of capsule provided here. So as of recently, I take one capsule of this supplement daily. Size is normal, taste neutral, my nerves feel fine, and that's about it regarding general qualities and benefits.
