Just updating ya'll on something VERY important!
I had a problem taking this plus an antibiotic, it litterally felt like my stomach was BURNING from HELL! Please check with your doc on all your meds while taking this! I am fine now but NEVER went through nothing like that before it was very painful! The antibiotic I took was Doxycycline for a throat infection from a bad cold, and laryngitis!
I stopped all use of everything including l-cysteine for several days , and stopped that antibiotics and got pro-biotics and just gave everything a chance to settle down , I am fine and have continued my use of l-cysteine now. But dont want anyone else to go through what I went through, and although I am not 'TOTALY' sure, I do think it was a combo of both the antibiotic and this sulphur amino acid that ultimately caused the issue
