> I wonder if it depends on what type of exercise one does? Is ammonia released more if it is aerobic or anearobic type of exercise?
In their report, Banister & Cameron (1990) wrote that ammonia is produced mostly from "fast-twitch muscle, particularly during intense (anaerobic) exercise." They cited evidence from four studies to support this statement. However, Banister & Cameron (1990) also reported that hyperoxia raises muscle and plasma ammonia levels, while "hypoxic acclimation" has been shown to reduce exercise-induced hyperammonamia during "submaximum exercise."
So, judging from the Banister & Cameron (1990) review article, it seems that the rapid "fast-twitch" muscle movements that are made during anaerobic exercise produce large amounts of ammonia over relatively short periods of time. However, the reduction in PO2 levels that results from anaerobic exercise appears to reduce ammonia. It might be the case that the metabolism that occurs in human muscles becomes anaerobic during periods of intense exercise as a way of compensating for the elevation in ammonia levels that follows rapid muscle movements, but I'm basically just speculating. Unfortunately, the evidence seems to be somewhat contradictory.

You're welcome. I hope that you notice some benefits from the taurine.
