It can't be predicted what mechanism is preferred by the body individually, at any given moment in
time; instead of using alkalizing minerals, it can, say, retain more of highly alkaline ammonia, from breaking down proteins, as acid
buffer, which could give to your sweat characteristic pungent smell; or it can use ammonia only after it runs out of alkalizing minerals, like calcium; note that buildup of ammonia can also result from
liver or renal dysfunction.
