Rated 1 out of 5 by from Seriphos still old formula? Interplexus has released the new, new version which is the original formula everyone liked. Swanson was going to order the current version which includes the Phosphorylated serine, but this page makes it appear they stocked the one no one liked. I hope they will correct the page and/or mistake. The new bottle has a red triangle in the upper left corner of the label and contains no phosphatidyl serine.

Rated 1 out of 5 by from Formula Change Interplexus has recently changed formula and not to a better one. Basically they have dropped Phosphorylated Serine and now they are using Phosphatidylserine instead, which is not effective for me and many regular buyers. I'm not going to buy it with the new fomula because it does nothing for me, I hope interplexus change their mind and return back to something that wasn't broken as the new formula is.

Rated 5 out of 5 by from Works great for sleep I take this with rhodiola rosea and holy basil leaf. I take it at bedtime because I often wake up in the middle of th enight and can't get back to sleep. Since taking this I have noticed a dramatic increase in the quality of my sleep.
