Review: Great supplement - I had no side effects at all from this supplement. It can be hard to know if a supplement is working (at least for me) but my research shows that this is an excellent supplement to deal with stress and to help related to stress with weight loss. I feel more energetic since starting it and I think that my memory is also a bit better. My weight loss has continued to be 1-2 pounds a week (no increase) but then again, no gaining weight even though I had to stop working out due to bronchitis.
Review: Very good - These have helped immensely with concentration and clear thinking

## Questions & Answers

**Q: Any idea if phosphatidylserine complex can lower dhea-s as well as cortisol?**
A: My understanding is that phosphatidylserine (PS100) if for brain functions.  Memory etc.  I like to think it helps. Never used that brand Source Naturals; Used NOW and have the next bottle by PURE which is decidedly more expensive that the others. Hope you get what you pay for.  PURE is also supplied by a couple of Drs.

**Q: what is phosphatidyl serine matrix and how does it differ from phosphaatidyl serine?**
A: As you notice is a complex they add more components to it God bless.

**Q: Is this made in the usa, or china?**
A: Thanks a lot for that question.  I have been using Metabolic Maintenance PS100 and am hoping it is not made in china.

**Q: Is this a good substitute for the Interplexus Seriphos product**
A: This is the best ever. It takes effect quickly. It doesn't have any side effects to.

### ⭐⭐⭐⭐⭐ Good for brain fog

I’d suggest two gel caps a day for a couple of months, or until you notice a difference. Then taper down to one a day. Good product, works well.
