Could a simple supplement shield kidneys from disease?
NCT ID NCT06441435
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested whether adding AC-134, a dietary supplement, to a low-protein diet helps protect kidney function in people with chronic kidney disease. Researchers measured kidney function, protein in urine, and waste products in the blood of 100 adults aged 20-90 with stage 3-5 disease. The goal was to see if this combination could slow kidney damage and improve overall health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AC-134 (a dietary supplement) combined with a low-protein diet
- What this could lead to
- If it works, this could point toward a simple dietary supplement that helps slow kidney decline in chronic kidney disease patients.
- What could go wrong
- This is a small, completed trial with no phase designation, so results may not be conclusive. The supplement's benefits are uncertain and may not apply to all kidney disease patients.
