Review: Healing my nervous system - I was researching how to heal my nervous system and increase cognitive function. In my research I found that PhosphatidylSerine along with Magnesium L-Threonate would help me. I’ve been taking them together for over 2 weeks now and I definitely feel the difference! My memory recall is much faster, I don’t have brain fog anymore, and I’m more focused. My energy has increased and my body wakes up on its on without an alarm clock. Of course, check with your doctor first, but I highly recommend it!
Review: Well-Formulated, Easy to Take, Subtle Benefits So Far - 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.

## 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.

Used everyyday will be using this to help w quality sleep.. also regarding this brand have switched about half of my supplemts this brand not disappointed. In AM.. Kanna, great start but not for everyday use. Also from double wood … other brands worked but not as strong and twice price
