Prebiotics
I am still taking them, it's been about 1.5 months. I do feel a little different, but still on Lexapro and do not really plan on coming off anytime soon (been on Celexa/Lexapro for 20+ years). I was just interested in some studies I read about and wanted to see what would happen.
I started using this for the first month and felt happier, but that was probably placebo effect - https://www.amazon.com/gp/product/B079H53D2B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Then I read a study about strands for depression/anxiety and found this, which I currently take. I personally felt better on the other one, but like I said I think it was placebo effect. I will take it for a few months and see what happens - https://www.amazon.com/gp/product/B00ZMO7UKW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Good luck.
