The Claim

Ingestion of sodium bicarbonate in a carbohydrate hydrogel does not increase gastrointestinal symptoms in trained male cyclists during prolonged high-intensity cycling in hypoxia compared to traditional sodium bicarbonate formulations.

Description
1 study reviewed
In plain English

When trained male cyclists consume sodium bicarbonate mixed in a carbohydrate gel during intense exercise in low-oxygen conditions, they experience the same level of stomach discomfort as when they consume sodium bicarbonate in traditional forms.

See the scientific wording

Sodium bicarbonate ingestion in a carbohydrate hydrogel does not increase gastrointestinal symptoms in trained male cyclists during prolonged high-intensity cycling in hypoxia, suggesting this delivery method minimizes a key limitation of traditional sodium bicarbonate formulations.

Why this might work

Sodium bicarbonate is enclosed in a thick gel made of carbohydrates, which keeps it from mixing with stomach acid until it reaches the small intestine. This prevents the acid from reacting with the bicarbonate in the stomach, which stops the buildup of gas and fluid that normally causes stomach upset. As a result, the bicarbonate is absorbed smoothly into the blood without triggering nausea, bloating, or cramps.

  1. Study: The effect of sodium bicarbonate mini-tablets in a carbohydrate hydrogel on prolonged high-intensity cycling performance and metabolism in acute normobaric hypoxia

    When cyclists swallowed sodium bicarbonate in a gel, they didn’t feel more stomach upset than when they took a fake pill — meaning the gel form works just as well without the usual tummy problems.
