Any idea if phosphatidylserine complex can lower dhea-s as well as cortisol?

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.

what is phosphatidyl serine matrix and how does it differ from phosphaatidyl serine?

As you notice is a complex they add more components to it God bless.

Is this made in the usa, or china?

Thanks a lot for that question. I have been using Metabolic Maintenance PS100 and am hoping it is not made in china.

Is this a good substitute for the Interplexus Seriphos product

This is the best ever. It takes effect quickly. It doesn't have any side effects to.
