The Claim

In adults with chronic kidney disease stages 3–5 and metabolic acidosis, sodium citrate results in a 22% increase in serum bicarbonate levels over 12 months, compared to a 16% increase with sodium bicarbonate, leading to a greater reduction in systemic acid load and slower disease progression.

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 with advanced chronic kidney disease and metabolic acidosis, sodium citrate raises blood bicarbonate levels more than sodium bicarbonate over 12 months, resulting in a larger reduction of acid in the body and a slower decline in kidney function.

See the scientific wording

In adults with chronic kidney disease stages 3–5 and metabolic acidosis, sodium citrate leads to a 22% increase in serum bicarbonate levels over 12 months, compared to a 16% increase with sodium bicarbonate, suggesting a more robust correction of acid-base imbalance, which may slow disease progression by reducing systemic acid load.

Why this might work

Sodium citrate is absorbed from the gut and converted into bicarbonate in the liver, which enters the blood to neutralize excess acid. This slow release avoids stomach irritation caused by immediate bicarbonate release, leading to more stable and effective correction of acid levels.

  1. Study: A Comparison of Sodium Citrate and Sodium Bicarbonate's Safety and Effectiveness in Treating Metabolic Acidosis in Patients with Chronic Renal Disease

    In people with advanced kidney disease and low blood bicarbonate, the study found that sodium citrate raised bicarbonate levels more than sodium bicarbonate did over a year, and it caused fewer stomach problems too.
