Standalone side effects

Adverse effect signal1 papers
Overuse of sodium bicarbonate is reported to cause severe toxicity, including metabolic alkalosis and associated electrolyte imbalances such as hypokalemia and hypochloremia.human · unknown
Adverse effect signal1 papers
Rapid development of acute hypernatremia and subsequent central pontine myelinolysis (CPM) was reported following intravenous sodium bicarbonate therapy in a patient with distal renal tubular acidosis.human · unknown
Gastrointestinal side effects1 papers
Common side effects include bloating, nausea, vomiting, and abdominal pain, which may negatively impact performance but are generally low in incidence and severity.human · systematic-review

CAP can mitigate GI symptoms induced with SOL and should be ingested earlier to induce similar acid-base changes, and may be more ergogenic in those who experience severe GI distress with SOL, although this warrants further investigation.
