[TheSomeBody]

so i am thinking that ritalin ruined my microbioms, my gut isnt the same, it gets better every day but suddenly things that where fine for me are now really painfull. lactos was fine, then it made me stomach pain , now i am eating small amount every day so i am fine with it . 2 days ago i at lots of soy beans and till now i have stomach pain , not so strong but still feeling it .
what probiotics i can take to get normal microbiom?
