The Claim
In elite rugby players, administration of sodium bicarbonate at a dose of 0.3 g/kg as a single bolus 90 minutes before training is associated with gastrointestinal distress that reduces the net practical benefit of the intervention.
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.
Elite rugby players who take 0.3 grams of sodium bicarbonate per kilogram of body weight 90 minutes before training experience gastrointestinal distress that diminishes the overall usefulness of this supplement.
See the scientific wording
In elite rugby players, the standard sodium bicarbonate dose of 0.3 g/kg administered as a single bolus 90 minutes before training is associated with gastrointestinal distress that may outweigh any potential ergogenic benefit, suggesting this delivery method is not practical for this population.
When a large dose of baking soda is swallowed, it pulls water into the gut and creates a sudden change in acidity, which stretches the intestines and slows down their movement. This causes bloating, cramps, gas, and the urgent need to use the bathroom.
What the research says
1 studyRugby players who took a big dose of baking soda before training didn’t get any stronger or less tired, but they did get way more stomach pain, gas, and cramps — and it got worse as they played. So the side effects were real and bad, with no upside.
