"I cannot take this. It made me extremely dizzy to the point of falling. The product itself is good and no issues with the company. This is just one of those supplements I can't use. So I'm giving it 4 stars."

My son has intellectual disability and I homeschool him. After taking the supplements, learning and retaining information seems to be much easier for him! I haven’t changed anything else in his diet or routine, so it feels pretty obvious to me that it’s the supplements making a huge impact on his ability to learn. This is so exciting! I’ve started taking them too in hopes that they will help me also as my memory doesn’t seem to be as sharp as it used to be.nusa

I’ve been taking this Phosphatidylserine 300 mg supplement for a period of time now and wanted to give a thoughtful review based on real use rather than short-term expectations.First, from a practical standpoint, the capsules are small and easy to swallow, which matters more than people realize—especially if you already take other supplements. No taste issues, no stomach upset, and no problem staying consistent.From a technical and clinical perspective, phosphatidylserine (PS) is a phospholipid that plays a key role in cell membrane structure, particularly in neuronal cells. It’s commonly used for:cognitive support (memory, focus, word recall)stress response and cortisol regulationage-related cognitive declinesupporting communication between brain cellsThere’s research supporting its role in modulating cortisol, which is why it’s often used for stress management and mental fatigue, especially when taken consistently over time rather than expecting immediate effects.As for results, I’ve noticed slight but real improvements, mainly in mental clarity and day-to-day cognition. Nothing dramatic or overstimulating—and honestly, that’s a good thing. This doesn’t feel like a stimulant or a quick fix. The changes are subtle, steady, and cumulative, which is exactly how this type of supplement is supposed to work.I’m realistic about supplements like this: they’re not meant to produce overnight results. Because of that, I plan to continue using it for a few more months to see whether the improvements become more pronounced with longer use.So far, I’m satisfied with the quality, dosing, and tolerability. If you’re looking for a clinically supported cognitive and stress-support supplement and are willing to give it proper time, this is a solid option.jm

SLEEP! Blessed sleep! This supplement was mentioned on the Freakonomics radio program by a doctor for use in overcoming jet lag as it suppresses cortisol. Wow, have only used it a short time but it has really helped me fall asleep and more importantly, stay asleep!What Customers Talk About
