The Claim

In adult kidney transplant recipients with metabolic acidosis, oral sodium bicarbonate supplementation at 1.5–4.5 grams daily for two years has no increased risk of serious adverse events compared to placebo, with similar rates of adverse events and three deaths occurring in each group.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In adults who received a kidney transplant and have metabolic acidosis, taking 1.5–4.5 grams of sodium bicarbonate daily for two years does not lead to more serious side effects or deaths than taking a placebo.

See the scientific wording

In adult kidney transplant recipients with metabolic acidosis, oral sodium bicarbonate supplementation at 1.5–4.5 grams daily for two years does not increase the risk of serious adverse events compared to placebo, with similar rates of adverse events and three deaths occurring in each group.

Why this might work

Taking sodium bicarbonate pills neutralizes excess acid in the blood, keeping the body's pH stable. This prevents the body from activating stress pathways that could damage organs or cause dangerous complications. The kidneys and lungs handle the extra sodium and bicarbonate without overload, so no harmful side effects happen.

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

    This study gave kidney transplant patients either baking soda pills or fake pills for two years and found that both groups had the same number of serious health problems and deaths. So, baking soda didn’t make things worse.
