The Claim

The current evidence base for sodium bicarbonate's ergogenic effect is limited by severe underrepresentation of female participants (only 16% of subjects), which prevents reliable conclusions about its efficacy or safety in women.

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.

Description
1 study reviewed
In plain English

Most studies on sodium bicarbonate as a performance enhancer have included very few women, so it is not possible to know whether it works safely for women based on current data.

See the scientific wording

The current evidence base for sodium bicarbonate’s ergogenic effect is limited by severe underrepresentation of female participants (only 16% of subjects), preventing reliable conclusions about its efficacy or safety in women.

Why this might work

When someone takes sodium bicarbonate, it increases a substance in the blood that neutralizes acid built up in muscles during hard exercise. This lets the muscles keep working harder for longer before getting tired. But this effect is stronger in men than in women, and because most studies used men, it is unclear if women get the same benefit or face different risks.

    Most of the people in the studies on baking soda and running were men, so we don’t really know if it works the same way or is just as safe for women. The study confirms that women were barely included, making it hard to say if baking soda helps them too.
