I am following the protocol of Italian researchers to, I hope, help restore my sense of smell lost with LC over 4 years ago. The product used is a very finely ground PeaLut called Glialia, which is a powder you keep under your tongue for 10 mins. designed to dissolve and pass the barrier between the body/blood stream and the brain. Since I’m so long without smell I spent the first month taking 2 sachets per day along with 1 alpha lipoic acid 600 mg pill, and smell training. I used to consider myself lucky if I had one smell a day, at the weekend I was conscious of say 4…so bit better. Food not smelling yet though! Not 100% sure if Epitech the manufacturers are selling in USA but I do know I GB company was selling to US. Try looking things up thru Uk charity Abscent ( though changed their name this year you’ll find a link)
