The Claim
Sodium bicarbonate supplementation increases anaerobic power by 21% and reduces fatigue by 37% in trained men during high-intensity exercise, and is associated with mild gastrointestinal discomfort.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In trained men performing high-intensity exercise, sodium bicarbonate supplementation increases anaerobic power by 21% and reduces fatigue by 37%, but causes mild gastrointestinal discomfort.
See the scientific wording
Sodium bicarbonate supplementation increases anaerobic power by 21% and reduces fatigue by 37% in trained men during high-intensity exercise, but is associated with mild gastrointestinal discomfort, suggesting it may enhance performance at the cost of tolerability.
Taking sodium bicarbonate increases the blood's ability to neutralize acid built up in muscles during intense exercise. This keeps the muscle environment from becoming too acidic, which allows the muscle fibers to keep contracting forcefully for longer. As a result, power output stays high and fatigue sets in later.
What the research says
1 studyThe study found that taking baking soda before intense exercise made trained men 21% more powerful and 37% less tired, just like the claim says—but it also gave them mild stomach upset. So yes, it works, but with a small downside.
