The Claim

Daily oral sodium bicarbonate supplementation at 1.5–4.5 grams for two years in adult kidney transplant recipients with metabolic acidosis increases serum bicarbonate from 21.3 mmol/L to 23.0 mmol/L and raises blood pH from 7.37 to 7.39, resulting in correction of metabolic acidosis.

In plain English

In adults who have had a kidney transplant and have metabolic acidosis, taking 1.5 to 4.5 grams of sodium bicarbonate daily for two years increases blood bicarbonate levels from 21.3 to 23.0 mmol/L and raises blood pH from 7.37 to 7.39, correcting the acid-base imbalance.

See the scientific wording

In adult kidney transplant recipients with metabolic acidosis, daily oral sodium bicarbonate supplementation at 1.5–4.5 grams for two years increases serum bicarbonate from 21.3 mmol/L to 23.0 mmol/L and raises blood pH from 7.37 to 7.39, demonstrating effective correction of metabolic acidosis.

Why this might work

When someone takes sodium bicarbonate pills, the bicarbonate enters the bloodstream and binds to excess acid, making the blood less acidic and raising its pH.

What the research says

1 study
  1. Study: Sodium bicarbonate for kidney transplant recipients with metabolic acidosis in Switzerland: a multicentre, randomised, single-blind, placebo-controlled, phase 3 trial.

    Taking baking soda pills for two years raised the blood’s bicarbonate level and made it slightly less acidic in kidney transplant patients, just like the claim says. It didn’t stop their kidneys from getting worse, but that wasn’t what the claim was about.
