The Claim

Sodium bicarbonate supplementation at 0.2 g/kg body weight does not significantly increase plasma markers of acute gastrointestinal injury (I-FABP) or endotoxemia (LBP, sCD14) during repeated sprints in 40°C heat among recreationally endurance-trained adults.

Source: Effect of sodium bicarbonate on performance and markers of kidney and gastrointestinal injury during repeated sprints in the heat.

Description
1 study reviewed
In plain English

Taking sodium bicarbonate at a dose of 0.2 grams per kilogram of body weight does not increase blood markers of gut damage or bacterial toxins during repeated sprinting in 40°C heat in adults with moderate endurance training.

See the scientific wording

Sodium bicarbonate supplementation at 0.2 g/kg body weight does not significantly increase plasma markers of acute gastrointestinal injury (I-FABP) or endotoxemia (LBP, sCD14) during repeated sprints in 40°C heat among recreationally endurance-trained adults, indicating it does not exacerbate gut barrier disruption under these conditions.

Why this might work

Taking sodium bicarbonate before intense exercise in hot weather neutralizes acid in the blood, which helps muscles work harder without damaging the gut lining or letting bacteria leak into the bloodstream.

What the research says

1 study
  1. Study: Effect of sodium bicarbonate on performance and markers of kidney and gastrointestinal injury during repeated sprints in the heat.

    Taking sodium bicarbonate before intense exercise in hot weather didn't make gut damage or bacterial leakage worse compared to not taking it — the study found no difference between the two groups.
