evidence
Performance evidence brief
Sodium bicarbonate
Useful for repeated high-intensity efforts and muscular endurance where acidosis limits output.
Headline Finding
Meta-analysis: endurance SMD 0.31-0.40; no clear strength effect.
Dose Context
Often 0.2-0.5 g/kg before performance; split dosing improves tolerability.
Important Caveat
High sodium load and gastrointestinal distress make it situational rather than casual daily use.

How To Read This Rating
The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
