Review: Helps the memory! - This stuff is great! It's one of the few things that will cross the blood brain barrier, and keeps your memory all together! We had my mom on this for a long time, then she stopped swallowing her pills, so we pulled them from her (she would chew on them ... ick) and after that, we watched her go downhill quickly, sadly passing in the next year. When she was on them though, she was talking, answering, chatting, we could carry on conversations ... off them, we got nothing. As I'm semi-retired now myself, I have incorporated them in my routine and I can say it helps too!

## Questions & Answers

**Q: How many mg of ps100 do you get?  is it a 500mg capsule of 60% standardized ps100 = 300mg?  or is it a 300 mg capsule of 100% ps100?**
A: Here was the email I sent to the manufacturer: The bottle says standardized to 20%.  So there is actually only 60 mg of Phosphatidylserine per 300 mg serving?  I’ve never seen “standardized” on this particular supplement before.  

There reply: Yes you are correct. All Phosphatidylserine are standardized, ours is standardized to 20%.

I see this as a rip off compared to Jarrow, Doctor’s Best, and some of the other more reputable brands.

**Q: I'd like to see the first question answered as to the actual concentration of a serving, with or without standardization!**
A: I ordered PS directly from double woods and the label on that bottle says “from non-GMO soy, Standardized to 20%

**Q: " Testing is available by request". Does this mean testing results are available? Just curious about the quality control assay results.**
A: Hello,

Yep! Just send an email to support@doublewoodsupplements.com for all testing or other order related requestions.

### ⭐⭐⭐⭐⭐ Helps the memory!
*by B***S on December 29, 2025*

### ⭐⭐⭐⭐⭐ Good brain supplement.
*by W***S on January 15, 2026*

PhosphatidylSerine Supplement 300mg is noted to be a good brain / memory supplement. I've used them for more than a year and they seem to be working for me.

### ⭐⭐⭐⭐⭐ Well-Formulated, Easy to Take, Subtle Benefits So Far
*by T***Y on February 4, 2026*

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 regulation age-related cognitive decline supporting communication between brain cells There’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.
