!! - WARNING - !!  THIS NEW (MAY 2016) SERIPHOS IS NOTHING LIKE THE PREVOUS SERIPHOS!!
1 Star
!! - WARNING - !! THIS NEW (MAY 2016) SERIPHOS IS NOTHING LIKE THE PREVOUS SERIPHOS!!
The sole intent of this review is to inform buyers that NO REVIEW of Seriphos before May of 2016 should be considered valid for ANY Seriphos purchased and received after May of 2016. The product has changed dramatically and so must be reevaluated with a clean slate.(People have been asking whether they recently received the original or the updated Seriphos. The labels note a different substance -- Phosphorylated Serine versus Phosphatidylserine -- and show their ingredients. To help clarify this I have attached an annotated scan of both the original and new Seriphos formulations.)In the late spring of 2016, the original Interplexus Seriphos formulation was dramatically changed. Initial anecdotal reports have indicated that the new formulation may no longer be effective. (See the comments to this review and any other RECENT reviews.) Upon learning of a previous edition of this review, the medical director/owner of Interplexus contacted me (by phone from France) to explain the changes they have made. He is extremely proud of the quality, purity, and integrity of the sourcing of their new formulation's ingredients. Based upon what he said, the good news is that no one will need to worry about contamination from foreign substances, lead, aluminum, other heavy metals, etc. or the presence of non-nutritional excipients. But, unfortunately, the bad news is that that this new Seriphos does not appear to be nearly as effective as the original. :(Both public information and private communication indicate that this new Seriphos contains no serine phosphate (thus the original name Seriphos) but now, instead, contains a comparatively low amount of high quality phosphatidylserine (PS) combined with high quality anti-stress minerals. I HAD been recommending the ORIGINAL Seriphos as part of an effective sleep-promoting formula I designed (Google: "Healthy Sleep Formula" for details) but that recommendation has now been switched to Swanson Vitamin's much more expensive 300mg "triple strength" Phosphatidylserine while I search for a lower cost replacement for the original Seriphos.If you would be so kind, PLEASE vote this review up, indicating that it was useful to you, so it will be seen by others who may otherwise base their assumptions of THIS new Seriphos upon the very positive opinions of the ORIGINAL (now discontinued) Seriphos.Thanks very much!/Steve.
