What does Sodium Bicarbonate do?

Alkalizing compound that buffers acid during intense exercise, modestly improving short-burst athletic performance.

Is Sodium Bicarbonate safe?

Can cause significant gastrointestinal distress (nausea, bloating, diarrhea) at performance doses of 0.3 g/kg — a well-documented side effect

Sodium Bicarbonate - Science-Based Research

What the Science Says

Sodium bicarbonate is a simple alkaline salt — the same compound as baking soda — that raises the pH of your blood and muscles. During high-intensity exercise, your muscles produce acid that causes fatigue; sodium bicarbonate acts as a buffer, soaking up that acid and delaying the burn. Studies show it can improve anaerobic performance and muscular endurance, and combining it with glycerol may also improve fluid retention before exercise. A typical dose used in research is 0.3 g per kilogram of body weight.

What It Doesn't Do

Won't help with endurance or aerobic sports in any meaningful way. Not a fat burner or weight loss aid. No evidence it builds muscle directly. The cancer-fighting claims you see online are based on very early animal and lab research — don't count on it as a cancer treatment. Won't replace medical care for serious conditions like hyponatremia or poisoning.

Moderate Evidence

Effective at: 0.3 g/kg body weight for performance (based on study doses)

Absorption & Bioavailability

Good — rapidly absorbed orally and quickly raises blood bicarbonate levels within 60–90 minutes of ingestion

Red Flags to Watch For

Can cause significant gastrointestinal distress (nausea, bloating, diarrhea) at performance doses of 0.3 g/kg — a well-documented side effect
High sodium content may be a concern for people with hypertension, heart disease, or kidney problems
Medical IV use (e.g., for hyponatremia or poisoning) is a clinical procedure — do not attempt at home
Transdermal and anti-cancer applications are experimental and not ready for consumer use
