sodium bicarbonate works very well at high doses (I forget
offhand). It also gives most people what they euphemistically
described as gastric upset (translate as: explosive diarrhea).
loading with dibasic sodium phosphate works too. 4 g/day for 4
days or 8 g the day before a competition. Twinlab used to make
a product (forget the name and it had a few other things that
might help) that contained it, dunno if they still do.
Cytomax, a drink used by endurance weenies, contains
polylactates that the manufacturer claims lowers lactic acid
levels but no study I'm aware of has ever demonstrated that
it does jack squat in this regards (cyclists still swear by
the stuff).
