I take L-Glutamine every day 
Be careful with the bone broth, as it’s very high histamine and very rich in glycine, of which the glycine can be converted into glutamate in the body.
Thanks Winter, noted on the bone broth, so far so good, but I will monitor

. How much l-glutamine are you taking if you don't mind me asking? I'm slowly upping my dose (at 1500mg currently, 500mg 3x a day between meals). I notice most "gut healing products" recommend 5000mg in a serving. didn't want to rock the boat with higher doses yet though.
I just recently FINALLY got rid of the benzo belly. This is how I did it......
by letting time pass.
It took 3 1/2 years for it to FINALLY go away.
Fortitude, thanks for the thoughts. Totally get it. So this is my 2nd taper. I successfully tapered off klonopin after a 2 year journey ending this past summer.
All my benzo belly went completely away when I was off the klonopin as you alluded to. I literally had zero stomach issues for about 4-5 months even towards the end of my taper. It was awesome! I still ate VERY healthy though because I had good habits built in from 2 years of dealing with benzos.
Now in my 2nd battle with klonopin/lexapro, I'm realizing that
FOR ME (and I emphasize
FOR ME, maybe not for others), my allergies are a key component of whats causing me so many of my "symptoms". I ALSO personally believe that mast cell activation and histamine sensitivity may have something MORE to do with my anxiety as well outside of the klonopin itself (a lot of things are becoming clearer with the more research and consultation I've been doing... we shall see though). So this thread has turned into more of a discussion on histamines and mast cell activation than "benzo belly" persay, I guess.
Of course, you are right, in the end,
we all just need to get off the benzos and let our body's heal. But I learned so much from my first taper, and
my 2nd taper has been so much easier due to supplementation that I learned from the first (magnesium/vitamin D/omega 3's have totally rid me of all my body aches/spasms and sleep issues from my first taper, what a win!!!). Was hoping to learn a bit more this 2nd time around. Anyway, that's the reason behind this journey and thread.
For others following and dealing with benzo belly, fortitude is of course correct, these symptoms will go away when you're clear of the benzos, could happen faster for some and slower for others, but yes, there is relief at the end of the tunnel for sure.
