I said to reduce ammonia levels not get rid of it.
"Lactulose inhibits bacterial ammonia production by acidifying the content of the bowel. It promotes growth of colonic flora. The growing biomass uses ammonia and nitrogen from amino acids to synthesise bacterial protein, which in turn inhibits protein degradation to NH3. Lactulose leads to less ammonia by inhibiting bacterial urea degradation and reduces colonic transit time... reducing the time available for ammonia production and expediting ammonia elimination."
"Lactulose reduces the presence of ammonia in the intestine by, on the one hand, the conversion of NH3 to NH4+ which low pH values promote, and, on the other hand, by suppressing ammonia-forming bacteria through bifidobacteria or lactobacillus. The fact that ammonia has a toxic effect on the brain explains the effect of lactulose as a therapeutic agent in cases of hepatic encephalopathy."
Anyway I just took 30ml of duphalac and I will keep the same dose 1x-2x a day. I can report the results if you want in a few days.
