A 2025 case study published in *Cureus* demonstrated that L-arginine supplementation can lead to a significant, yet artificial, increase in serum creatinine levels. This is a key distinction for supplement users, as a high creatinine reading does not always mean poor kidney health.

Recent case studies and clinical reports have documented that taking L-arginine supplements can lead to a measurable increase in serum creatinine. This elevation, however, is often an 'artificial' increase caused by the supplement's metabolic process rather than a sign of true kidney dysfunction.
