The Claim
Sodium bicarbonate supplementation at 0.2 g/kg body weight has no significant effect on urinary biomarkers of acute kidney injury (IGFBP7×TIMP-2, IGFBP7, TIMP-2, NGAL) during repeated sprints in 40°C heat among recreationally endurance-trained adults, and does not alter the risk of acute kidney injury under these conditions.
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.
Taking sodium bicarbonate at a dose of 0.2 grams per kilogram of body weight does not change levels of specific urinary markers linked to acute kidney injury in endurance-trained adults performing repeated sprints in 40°C heat.
See the scientific wording
Sodium bicarbonate supplementation at 0.2 g/kg body weight does not significantly affect urinary markers of acute kidney injury (IGFBP7×TIMP-2, IGFBP7, TIMP-2, NGAL) during repeated sprints in 40°C heat among recreationally endurance-trained adults, indicating it does not reduce or increase AKI risk under these conditions.
Taking sodium bicarbonate before intense exercise in the heat makes the blood less acidic, which helps muscles work harder by removing acid faster. This does not change how the kidneys respond to the stress of exercise and heat, so the markers of kidney stress in the urine stay the same as when no supplement is taken.
What the research says
1 studyTaking sodium bicarbonate before hard exercise in hot weather didn’t change the kidney stress markers in the urine — so it neither helped nor hurt the kidneys during the workout.
