Of course it does but the level you can get away with works better if it is potassium bicarbonate.
Potassium bicarbonate (KHCO₃) is not a common performance-enhancing agent in equine sports, and there is no established, widely accepted test protocol for detecting it in racing horses. Unlike sodium bicarbonate, potassium bicarbonate does not produce the same predictable blood gas changes, and its effects on pH and electrolyte balance are less studied in horses. This lack of a standardized detection method means that potassium bicarbonate is not typically monitored in the same way as sodium bicarbonate.
Why sodium bicarbonate is banned:
Detection: In horses, studies show that NaHCO₃ administration increases blood pH, HCO₃⁻, BE, and Na⁺, while lowering K⁺ and CaČ⁺
These changes can be measured in blood samples.
Regulation: Most racing bodies prohibit NaHCO₃ use close to competition due to its performance-enhancing potential and detectability.
Potassium bicarbonate in racing:
Not banned in the same way: Because there is no reliable, standardized test for KHCO₃, it is not routinely monitored in racing.
Possible performance effects: In theory, KHCO₃ could buffer acid similarly to NaHCO₃, but potassium is a major intracellular electrolyte, so large doses could disrupt nerve and muscle function. This makes it less likely to be used intentionally in racing.
Detection challenges: Without a validated analytical method, potassium bicarbonate would be difficult to detect in blood or urine samples.
In summary, sodium bicarbonate has a well-established test in blood gas analysis, while potassium bicarbonate does not, making it harder to detect and less likely to be regulated in the same way.
